P2p routing

I have 7 flexrio cards 5 7965 and 2 7961 and am heavily using P2P streaming to transfer data between them. The chassis is a PXIe-1065. Having enable all the P2P connections is there anyway of knowing which of the links go by the backplane switches and which have to use the host PC?

The P2P connections should all take a direct (or the most direct) route to each other:
From looking at this diagram, I can say that P2P connections on boards 9-14 should route through the chassis' PCIe Switch and should therefore communicate at expected P2P speeds.
A P2P connection to a card in slot 7 or 8 will be entirely dependent on the architecture of the controller. In addition to this, if multiple streams are transferred through the same switch then the 800 MB/s maximum transfer speed will be distributed (Two simultaneous transfers using four cards should mean that you experience a transfer rate slightly below 400 MB/s). Does this fit with the pattern of data rates you are experiencing?

  • VPN -- Point to Point Connection Routing.

    The VPN is up and running between Site C and Site A. No problem there.
    I can ping 10.2.24.1 from Site A P2P Router.
    But I cannot ping from Site B P2P Router. The ping times out.
    I have the following routes on 3 routers,
    Site A P2P Router: ip route 10.2.24.0 255.255.255.0 172.16.5.3
    Site B P2P Router:  ip route 10.2.24.0 255.255.255.0 172.16.5.3
    Site B Router Gateway:  ip route 10.2.24.0 255.255.255.0 172.16.5.3
    When i start a ping from 172.20.3.0/24 network, Site C see the ping coming from 172.20.3.0 network and sends out a reply. But I never get a reply and i get a request timed out.
    My task is that i should be able to ping Site C from any machine at Site B

    Your next hops should be 1 away unless you are running a dynamic routing protocol.
    Change:-
    Site B P2P Router:  ip route 10.2.24.0 255.255.255.0 172.16.5.3 change to
    ip route 10.2.24.0 255.255.255.0 172.16.1.5
    Site B Router Gateway:  ip route 10.2.24.0 255.255.255.0 172.16.5.3 change to
    ip route 10.2.24.0 255.255.255.0 172.20.3.2
    And ensure the correct IP subnets are part of the interesting traffic acl and the no-nat acl.

  • P2P Blocking is disabled in cisco 881 W router

    Hi
    We are facing an issue with the communication between wireless clients in same subnet .These users are not able to ping each other in cisco 881 W wireless router.
    But we can do in this router to disable this P2P blocking.  

    Well I would use a static on the AP, but if you depending on IOS dhcp to be reliable, then maybe you need to setup a Mac reservation for the AP. It would be after to just set a static on the AP. Since you know your environment will grow, it might be better that you start setting them to static. IOS dhcp isn't 100% reliable as you have already experienced.

  • Does Stratus/RTMFP support P2P behind the same NAT/Router?

    Does Stratus/RTMFP support peers behind the same NAT/Router?
    (such that both peers have the same public IP address)
    That is: if two computers (each running Flash) are behind the same NAT, and connect to Stratus to get peerID;
    do we expect they can connect p2p?
    Or will each one get/see just the public IP address:port of the other?
    My initial tests indicate that this scenario fails [ICMP Destination Unreachable (port unreachable)]
    Is this just a limitation of my local router? does this work for others?
    Does Status expect the local router to detect/decode/resolve this situation?
    If the solution requires 10.1 groups, is there support to detect/diagnose when/if the peer is on the same LAN?

    Thanks for the info, sounds like RTMFP supports this, and hopefully the AFP code does the right thing.
    [so, officially, the original question is answered]
    Note: In one instance, i'm running two browsers on the same host,
    so even the inner/LAN addresses would be the same. Therefore, if A sends to B's inner/LAN address,
    the [Windows] OS network layer *should* recognize that and 'hairpin' without leaving the host, or crossing the firewall.
    (I say "should" because Unix generally does that, but I'll have to check to see about Windoze).
    [And such packets are probably invisible to Wireshark also, so how do i verify what's happening?
    oh sure, just reconfigure to boot Linux... ]
    So glad you explained that the client tries all three pathways; if it works as you say,
    then I can probably ignore the ICMP error from the local router (or, as you say, teach it to do the hairpin).
    Can you confirm that P2P will work between browsers (say Chrome to Firefox) on a single Windows host?
    [I really want to know if I'm failing because of network configuration or application code/error;
    at this point, I am able to correctly exchange the peerIds, and start the NetSteam.play,
    but the two sides do not appear to be exchanging audio/video]

  • Blocking p2p on router 877

    Hi,
    Can anyone suggest how can I effectively block p2p traffic like Ares, Limewire or other with Cisco IOS 12.4(6) or higher? I tried NBAR but I guess there is no PDLM available for Ares for instance.
    Many thanks for any suggestions.
    Remi

    Hi,
    to block p2p traffic you need to block all ports except these you really need.
    For example block all ports except http, https, smtp, pop3, dns.
    Becouse some of the p2p applications use port 80 to connect there is an options in firewall(classic or Zone-Based Policy Firewall) called protocol-violation and port-missue!
    This options prevent non-HTTP traffic over port 80.
    For Zone-Based Firewall reffer to this link:

  • Wrt54gs loses internet connection when using P2P Ares

    I have a wrt54gs v5 and I've installed the latest firmware and reset back to factory then reconfigured.  Whenever Ares is started all other computers (wired or wireless) lose their inet connection.  Within 2-5 minutes of stopping Ares everything starts working again. I've checked Ares and it's set to am max of 10 connections. 
    I've hooked up my old befsx41 and it works fine but I need the wireless.  Both of these are talking to a befcmu10 cable modem.  I've never had problems with linksys before but from what I'm seeing on the forums the wrt54xxx doesn't seem to be of the same quality as the oldser stuff. Anyone know of any specific versions that fix this?
    (Mod Note: Edited for guideline compliance. Thanks!)
    Message Edited by Maximus on 07-04-2007 02:13 PM

    Since your BEF works with P2P, why don't you simply convert your WRT into a WAP (wireless access point).  This way you will use the wireless of the WRT, while using the BEF to handle all the routing chores.
    To do this, setup the BEF as your primary router.
    Then wire one computer to port 1 (not the Internet port) on the WRT.  (Note:  Disconnect everything else from the WRT at this time.)
    Then in the WRT do the following:
    Turn off the DHCP server.
    Set the "Local IP address" to 192.168.1.2  (assuming no other device on your network is using this fixed LAN IP address, and assuming the BEF is set to use the 192.168.1.x  address space.)
    Save your settings.  Power down the WRT.
    Next, connect any numbered port on the WRT to any numbered port on the BEF.  Do not connect anything to the Internet port on the WRT.
    The BEF will control your router settings (DHCP server, port forwarding, etc.)
    The WRT will control your wireless settings.
    Please let me know whether this setup allows your P2P to work properly.

  • Report a bug, if this problem is not solved, p2p of rtmfp will not be of much use

    Recently, we have several clients on a p2p application, but we use the development version to test, two-way voice and video connection is not successful, several customers of the network environment is as follows:
    First of all, there is no firewall;
    These networks have in common is:
    After an optical access, the subnet with a lot of routers, one by one, and some series, some parallel, some in series and then parallel, and some in parallel then in series, in short, they can be online, and then not the same segment of the computer, p2p connection is not successful, and other computer connection is not successful, and some also use the vpn.
    Analogy: 192.168.5.10 and 192.168.10.10 to connect not, 192.168.5.10 and 192.168.5.11 is ok, is 192.168.5.10 may be outside the network of other computers can connect to, but 192.168.10.10 possible and other computers outside the network connections are not.
    Hope you solve this problem as soon as possible, because rtmfp too expensive, otherwise p2p applications, are generally large companies (schools, government) affordable, and their networks are very complex, they do not take, you will no client .
    My English is not very good, google translation
    I gave you a bug report so long, how did not care for me ah;
    This forum nobody, or you did not test this bug, you do not have time to correct this bug;
    Either we modify not the flash player platform to the bottom of things, I will not give you advice.
    In fact, standing on a technical point of view to think that I have is to use a socket network communication can be OK, network barrier, it is not.
    But would like the user's perspective, I can be normal to the Internet, other p2p communications software, I can, on this thing, impossible, it is this software not work, so that this bug is that we must solve the .
    I am very concerned about this issue every day and came to see nobody replies, I think this problem, I think, to solve this problem, you can proceed in two ways:
    1.dns
    I think it may be able to solve this problem, dynamic dns,
    The idea is: to allow users to connect to the server, the user computer first upd listener (that is, iis services), then farid + domain to form a secondary domain name server dynamically to resolve the domain name to the user's computer, in a timely manner to refresh dns.
    In this way, the user's computer, there is a fixed identity.
    2 gateway
    From users within the LAN to solve this problem, it can only proceed from the gateway.
    For example, to use arp and other means to get to the router, where each segment ip then ip, similar to the route command to specify more than one gateway to the user's computer may be able to solve this problem.
    In theory, these two methods may be feasible.
    We also expect a new solution, I do not know Daoxing not
    Speak before this program, take a look at our test for RTMFP p2p network topology, and the test results (explain, test, do not open the firewall and router are not set up static routing).
    Computer A, computer B - "router A -" server S
    The above NetConnection.Connect.Success 95% NetStream.Connect.Success 5% NetStream.Connect.Fail
    Computer A - "Router A - servers S" - routers B - Computer B
    Above, NetConnection.Connect.Success, NetStream.Connect.Success
    Computer A - "Router A - servers S" - router B - routers C - Computer B

    Above NetConnection.Connect.Success, 100% NetStream.Connect.Fail
    See the above test results, is not very bad, the key is FMS4.5 sell 450,000 RMB in China, their own software does not do a good job, but also to sell such a high price in China, a man named QQ. The above test environment, all 100% NetConnection.Connect.Success 100% NetStream.Connect.Success, free, QQ has more than 100 million users, QQ companies rely on advertising to make money game.
    Seems to digress, huh, huh.
    The test results, 100% NetConnection.Connect.Success, and NetStream.Connect.Fail the main reason is because the route connected in series or more than two or two and then caused.
    From a technical perspective, as a packet travels through a number of the NAT router default all packets can be out, new packets can not be into the second layer of the router caused.
    Find the reason, we think of a countermeasure to solve this problem from the software itself.
    The last case of the above test environment, for example:
    When computer A and server S NetConnection.Connect.Success computer B with the server the S NetConnection.Connect.Success, computer A to Router D sends an upd packets, not because the router can only broadcast the data packet to computer B, so 100 % NetStream.Connect.Fail.
    The 100% NetConnection.Connect.Success, if we can NetStream.Connect, and NetConnection.Connect connected together, is not can be 100% NetStream.Connect.Success?
    In other words, no matter what circumstances, computer A and computer B can and server S connection is successful, the other way round, that is, the server S and the Computer A or Computer B can connect.
    We can not let the computer A or computer B, pretending to server S (In theory, called NAT, technically speaking, is to modify the source ip of the packet header and source Mac server S, and parity), the router not in the NAT, and other communications.

    Hi Mr. Wog,
    My guess is that once you see an estimate for replacement for hundreds of dollars, those scratches won't look too bad anymore. There are products to cover the outer casing, and some people put stickers on, or even paint (I don't recommend either, but ymmv). Good luck.

  • I want to set up my router for Peer To Peer connection.

    I recently started playing a new game that requires Peer to Peer connection, and I lag a lot when I log in, so I was wonder what options I would have to check, How to enable/disable options to optimize my gaming connection.
    What kind of router I have is MI424-WR Rev. E Actiontec. Or something along that line.. I was researching what to do and it had a lot to do with DMZ, Ports, and firewall. But any help would be appreciated.
    Im off for tonight so I wont be able to check the post until like 9 hours from now. Goodnight
    Oh if you need to know what game it is for some odd reason its Dungeon Fighters Online, or http://dungeonfighter.nexon.net/
    I like arcade style games.
    Oh and my brother connects to this router to and i want him to keep internet so none of the options can interfear with his internet connection.

    I took a quick look at the www site for the game, but did not see anything definite from the vendor on what port(s) the game uses. 
    You would need to set up you gaming machine with a Static TCP/IP Address and configure the Verizon Router with Port Forwarding of the ports used by the game.  I would ONLY set it up in the DMZ if all else fails.
    Note that the Verizon Router has a small NAT Table which may effect your ability to play a P2P game for extended periods of time.

  • About Flash P2P live streaming from non-webcam sources

    Hello, I am a university student. Our lab is attempting to work on a p2p live streaming using flash p2p features. The media source is not from a webcam but a file from a certain server, which is not directly supported by any of the 4 methods flash player offers(posting, direct routing , object replication,and multicast.) As some of the forum threads mentioned, our method is to use NetStream.publish() a stream and use send("callbackname", data)  to all subscribers that have joined in a NetGroup. So we can use p2p transmission. Now here are our questions:
    1. We know from MAX 2009 that flash p2p camera video multicasting implements pull-push mechanism inside which makes full use of p2p features like buffer map exchange. If we use NetStream.send() API to send non-webcam source data, will it also make use of this pull-push mechanism to spread data among all peers(subscribers) with proper data exchange?
    or more detailedly,
    I saw the P2P Gaming Libs at flashrealtime.com. It uses DIRECT_CONNECTIONS when creating publish-used NetStream in order to send data with lowest latency. My question is if I do not use DIRECT_CONNECTIONS, than when the NetGroup grow large (1000), will those peers that are not direct neighbors to the publisher in the same group relay data to each other using pull-push via buffer map?
    2. I have written a sample app and use send() to deliver data only (NetStream.bufferTime = 0) without camera video and audio. When the publisher sends the data  in a "for()" stantence for 20 times, the subscribers can only receive about 8 of them. But when I set a timer and periodically send them(e.g., 500ms), the subscribers can receive them correctly. My questions are: Is the packet loss caused by UDP unreliability? Can this be solved by setting the NetStream.dataReliable = ture? Can this totally be solved by setting a timer? How to set the delaytime property in timer? Are all data sent are orderedly received?
    I'm very appreciated if you can answer my questions? thanks.

    1. NetStream.send() data is delivered in the order it was sent, whether in client-server, DIRECT_CONNECTIONS, or multicast mode.
    2. the lowest latency will be achieved with DIRECT_CONNECTIONS.  however, that isn't scalable to large numbers of recipients.  the P2P multicast system trades low latency for scalability.
    3. there are no plans to support a natural NetStream streaming source that's not a camera/microphone.  Flash Media Server can perform that function.
    4. you should never need to implement "bitmap exchange"; the object replication system handles all the communication needed to accomplish its function. typically you will divide a file into segments, giving each one an index number. object replication uses ranges internally, so the index numbers should be contiguous.  nodes that have indices use NetGroup.addHaveObjects().  nodes that want indices they don't have use NetGroup.addWantObjects().  nodes that have objects will send them to nodes that want the objects.  when a node receives an object, it's automatically removed from its "want" set; once the node decides the object is acceptable, it adds it to its "have" set, at which point it can answer requests from other nodes who still "want" it.  eventually every node will have all the pieces and not want any.  for an example, please see Tom Krcha's articles on using object replication:
       http://www.flashrealtime.com/file-share-object-replication-flash-p2p/
       http://www.flashrealtime.com/video-on-demand-over-p2p-in-flash-player-101-with-object-repl ication/
    5. please see Tom Krcha's articles.  for VOD you will probably want to use the "LOWEST_FIRST" replication strategy, as that may allow you to start playing earlier.  for general file replication you'll get better sharing if you use RAREST_FIRST.

  • Is it better to use router port versus vlan member port?

    Hi CSC,
    This is more of a philosophical or "best practices" question.
    I have a Cisco 3550 at the home office. Connected to the 3550 is a number of branch offices by way of T1 circuits or VDSL modems. They all come to the home office, where we have a central internet connection and server farm for our entire organization.
    Except for one special case branch office, we don't forsee the need for appearances of the  home office vlan at the branch office sites. In that case, we bring it  into a trunk port at the home office, and at the special case branch office we have a dell 3024  switch and tag some ports as vlan 18 (the home office) or vlan 27 (the  special case branch office).
    We also do not forsee a need for the vlan from one branch office to appear at another branch office.
    They are all (except for the special case mentioned above) currently configured something like this:
    interface FastEthernet0/1
    description home office
    switchport access vlan 18
    switchport mode access
    interface FastEthernet0/2
    description t1 to branch office 1
    switchport access vlan 19
    switchport mode access
    interface Vlan18
    description subnet for home office
    ip address 192.168.18.1 255.255.255.0
    interface Vlan19
    description subnet for branch office 1
    ip address 192.168.19.1 255.255.255.0
    Is it better, in terms of reduced network complexity or performance on my 3550, to do something like this instead?
    That is, to make the interfaces router ports as opposed to vlan member ports?
    Of course, if we ever DID need to have appearances of the home office vlan at branch office sites, or appearances of one branch office's vlan at another branch office, we would lose that flexibility.
    interface FastEthernet0/1
    description home office
    switchport access vlan 18
      switchport mode access
    interface FastEthernet0/2
    description t1 to branch office 1
    ip address 192.168.19.1 255.255.255.0
    interface Vlan18
    description subnet for home office
    ip address 192.168.18.1 255.255.255.0
    no vlan 19

    Hello,
    In my opinion there is no 100% right answer here. I think it depends also about network forecast. I'll try to add here some thoughts:
    - if you use trunk interfaces from home to branch and SVI for L3 connection, in terms of scalability is much easier to expand (you have now only one p2p L3 link, but in future you'll need another one; if the port is a trunk one, you just configure another SVI interface, allow vlan on trunk and your good to go)
    - trunk interfaces involve more configuration (L2 interface and SVI L3 interface)
    - if you add in the home office another switch to existing one, and for some reason you have misconfiguration in STP / VTP, then you can run into problems like loops, vlan database modification (e.g. VTP server mode and the new added switch has a higher revision number than existing one)
    - L3 physical interfaces are easier to configure and less complex, but in case you want to scale to additional p2p link will be harder
    - L3 configuration is easier to troubleshoot as you avoid the L2 complexity
    - in terms of packet exchange a L3 interface will exchange less packets than a L2 trunk with SVI (I'm talking here about control traffic, not user traffic)
    - with L2 trunk you can have other problems like if somebody is "smart enough" to add a new switch into the existing switch (if you have a switch there) at the branch location; imagine that the new switch due to misconfigurated STP became root bridge; you have a large STP domain.
    As I said, there is no good or bad approach. You have to guide yourself about forecasts in your network. For example if you know that a branch location will not be extended in the next 2 years, then go ahead with L3 interface and that's it. On the other hands if you have doubts you can add for another location L2 trunk with SVI. You can mix this two solution to obtain the best results for your network characteristics.
    Cheers,
    Calin

  • Eigrp routes doesn't refresh when neighbor down

    hi guys, need some tips for troubleshooting an ongoing issue, but can't do the changes anymore untill next call and yes the issue is still ongoing.
                           WAN1 <--------------------------------------------------------------------------------------------> WAN2
                               |                                                                                                                                       |  
                       metro ethernet ME-3600X-A  <----> ME-3600X-B  <----->  ME-3600X-C<----> c3560v2
    I have 3 metro ethernet switches and a c3560v2 switch connected as above. The WAN1 redistributes all routes to ME-3600X-A's eigrp and WAN2 redistributes all routes to c3560v2 's eigrp and these two propagates all their eigrp routes to ME-3600X-B and ME-3600X-C  which are in the same eigrp AS. And all link/connections are point-to-point.
    Now, when the link between ME-3600X-B  <----> ME-3600X-C is physically disconnected, the ME-3600X-C's eigrp still points the route(s) to the ME-3600X-B's p2p ip as its next-hop - which is down(neighborship between them goes down, but still the routes doesn't refresh/rebuild). However, switch c3560v2 has route to the same network learnt from WAN2.
    Wonder why, need inputs please? Thanks.

  • Configuring Frame-Relay and the Frame-Relay Switch To Participate in WAN Routing

    Hey,
    My WAN in my voice lab is currently functional between all of my routers HQ, BR1, and BR1 with full-mesh connectivity.  I am using my PSTN router for the frame-relay switching as is shown in the attached configs.  I have used the connect commands for the PVC routing logic.  
    connect HQ-BR1 Serial0/3/0 101 Serial0/2/0 201 
    connect HQ-BR2 Serial0/3/0 102 Serial0/2/1 301 
    connect BR1-BR2 Serial0/2/0 202 Serial0/2/1 302 
    My question concerns the possibility of getting the PSTN router to participate in the WAN and the OSPF routing process?  The connect command tells how the PVCs are to be connected and pass through the PSTN router.  Is there anyway to do it so that a PVC connects to the PSTN router itself?
    I would specifically like to create a connection between the HQ and PSTN router over the WAN.  If anyone has any insight on this I would really appreciate it.
    Thank you.

    Hello Adam,
    you don't need to do FR switching.
    You just need to configure a back to back PVC associated to a p2p subinterface under PSTN router interface se0/3/0 and HQ:se0/1/0. the new PVC can be 103 on both sides
    PSTN
    interface ser0/3/0.103 point-to-point
    ip address 10.1.13.1 255.255.255.0
    frame-relay interface-dlci 103
    HQ
    interface ser0/1/0.103 point-to-point
    ip address 10.1.13.1 255.255.255.0
    frame-relay interface-dlci 103
    note: I was able to do this using the older syntax frame-relay route under interface configuration on frame relay switch. I would expect to work for you too with newer syntax connect.
    Hope to help

  • Router drops connection

    Hi, I have a WRT300N that acts as a router/DHCP in a small home network. I have a p2p program, DC++, which requires port forwarding to work correctly. I have setup this in the router, port 1412 and the computer ip address to forward to. The problem is that the router drops connection to internet now and then, with 1-2 hrs. intervals which disconnects all hubs and downloads/uploads in DC++. Very annoying indeed. This has never happened with previous routers including a 3com and a Zyxel, so it has to be something with the WRT300N. What can cause this? I'm not sure what information to send with this message, so it's better if you tell me what you need. Thanks in advance, Mattias Sarling

    hi... try upgrading latest firmware on the router, go to www.linksys.com/download and download the latest firmware for the router, after upgrading firmware on the router, reset the router back to factory default settings and reconfigure it according to ISP settings, reduce MTU to 1458, try reducing connection on p2p program... also you can enable QoS to manage bandwidth.

  • Linksys and P2P problems?

    Hi all,
    I'm aware of the problems (or firmware bug) with Linksys routers and P2P software, where too many connections crash the router. I had a WRT54G v2 sometime ago and had to reboot the router twice weekly, before it died.
    Well time has come for me to get a new wi-fi router for my Wii.
    Have the problems been fixed yet concerning the mentioned bug with newer firmware, or should I get a router from another manufacturer.
    I can't believe that a networking company, as Cisco would allow such a bug to exist for so long.
    Thx 

    Access the setup page of the router by launching an
    Browser and type on the address bar, 192.168.1.1 and press enter. When
    it prompts for the username and password, leave the username field
    empty and provide password as "admin" (Without quotes)
    click on ok.
    On the main setup page the ""Internet Connection Type"" should be
    on ""Obtain IP Automatically - DHCP “. Click on the Save Settings
    button.
    Now click on the sub tab ""MAC address clone"".
    - Click on enable
    Click Clone & click save settings
    Check WAN Ip on Status page of router ....
    If getting Valid Ip .... try going online
    If you are getting Ip - 192.168.1.X ...change the LAN Ip to 192.168.2.1 ....Power cycle for 3-4 minutes ...
    Try going online
    If still not working ...use Internet Connection type as PPPOE .... Use Username & Password provided by Service Provider ....
    Click save settings....
    Look for WAN IP address again under status page ....
    Try going online ......
