MPLS VS POINT TO POINT

I need a document explaining the advantages and disadvantages of converting point to point connectivity to
MPLS and the plan / suggestion to overcome the disadvantages

Hi,
The answer depends on your requirements.
QoS (here: queueing) is a per interface feature and the encapsulation does not change much. The methods will also be the same (LLQ/CBWFQ).
A MPLS VPN solution offers some advantages, when connectivity between many sites is required AND many customers with overlapping IP addresses are present.
It allows a SP to setup a shared backbone resulting in lower costs per customer.
Depending on your requirements either solution could be best for your network.

MPLS vs Point-to-Point over Citrix Performance Difference

We run Citrix at our remote locations. We have two circuits at each location. One is a point to point for backup and the other is an MPLS circuit that is our primary. Both circuits are T-1 speeds.
We have all thin clients at our remote locations. When communication goes through the point to point circuit it utilizes much more bandwidth. Maybe 1.2 Mbps on average but when we communication through the MPLS circuit only 800 Kbps of bandwith is actually being used.
Can anyone explain this? I was thinking that maybe MPLS does a faster job of switching the packets across the WAN and that the Citrix does not need to use as much bandwidth because of this. This analyis was completed across all of our sites and in each case Citrix uses more bandwidth on a point-to-point vs an MPLS circuit. I have not had any users complain when accessing either ciruits.
What do you think is causing this?

Hi,
I fully agree with Swaroop. Being an instructor teaching many MPLS classes I was frequently confronted with the opinion MPLS is "faster" as it is "switching". This is not true and I always countered this - provocantly - stating that MPLS is reducing throughput, so it is slower! What I mean writing this: given a certain topology for IP forwarding and turning on MPLS on it will increase the overhead (additional overhead by adding labels) and thus reduce end to end IP throughput. The lookup is done by the same algorithm (CEF) at wire speeds for IPv4 and labeled packets - there is no speed gain for either technology.
Do not get me wrong, this does not mean MPLS is "bad" and in fact the difference between pure IPv4 forwarding and MPLS forwarding is marginal and most likely irrelevant for any real environment. The advantages of MPLS are plenty and thus a marginal throughput difference is not the most important thing to consider.
I guess the idea of "switching is faster than routing" stems from the fact that there were times, when IPv4 forwarding ("routing") was done in CPU, thus was slow, whereas L2 forwarding ("switching") was done in hardware and thus was faster. It dates back to those days where we used AGS+ (an old router, which is EOS, EOL and most likely even EOeBay ;-) and f.e. Cat5000.
Now coming back to the observed behaviour in the original post there might be some reasons to explain it:
1) different L2 overhead as pointed out by Swaroop, especially as I would assume rather small average packetsizes.
2) Additional traffic on the P2P link not sent through the MPLS cloud - check your routing, if it is exactly the same for both links.
3) Measurement artefacts - as Swaroop pointed out. Is the load interval the same for both interfaces? I would rather use a packet analyzer than only go for a "show interface" to get precise values.
Hope this helps!

Link Redundancy Mpls primary on ethernet & point to point secoundary leaseline on serial

hi i am having one link mpls with internet (primary) (e0/0)-10.1.1.1 and secound link point to point serial (s0/0) i want to do redundancy between two links
but problem is mpls link never shows down . so if mpls fails then my point to point should be up please Find Attach file.
can i get confuration according to my e.g. drawing
as per my knowledge ip sla track command is thier but i dont know exact command.

Hi,
You are right...You should use IP SLA to track the primary link (ISP side IP)....
Try these...
track 125 ip sla 10 reachability
delay down 15 up 10
ip sla 10
icmp-echo 4.2.2.2 (change this with the exact IP) source-interface Dialer1
threshold 40
If it doesn't work, just tewak some parameters..Some the methodilogy remain same..
Good Luck !!!!

Why we choose mpls over point to point only because it is cheap

I need a document explaining the advantages and disadvantages of converting point to point connectivity to MPLS and the plan / suggestion to overcome the disadvantages

Hi,
Converting a network that consists of point-to-point links to run MPLS can have benefits. This is regardless of the type of links you have in the network.
One starting point could be this one:
http://en.wikipedia.org/wiki/Multiprotocol_Label_Switching
The big benefit that comes with deploying MPLS in your network is the ability to run the MPLS applications. Here are the most important ones:
-MPLS VPN - Layer 3 (with multicast)
-MPLS VPN - Layer 2 - point-to-point or point-to-multipoint
-MPLS Traffic Engineering - point-to-point or point-to-multipoint
Each of these have their benefits, while running over a one common network : an IP network with MPLS enabled.
The most important benefits are:
L3 VPN : obviously gives you seperated VPNs, with the possibility of overlapping IP subnets
extreme easy provisioning of layer 3 VPNs
L2 VPN: supports transporting most supported layer 2 protocols, even protocols with clocking information
MPLS TE: steering of traffic through the network and extremely fast traffic protection
These are just the most important ones.
All of these applications run on one common network, while before MPLS, one needed to have multiple carrying networks (e.g. one Frame-Relay network, one ATM network, one IP network) in order to provide all the same functionality.

Design Help with MPLS/BGP and Point to Point VPNs using OSPF as backup

I need some advice on the configuration I want to implement. Basically we have a MPLS cloud using BGP. We are using OSPF for internal routing. Everything is working fine. Now we want to add a Point to Point VPN using new Cisco ASA's for a backup path at all of our remote locations. We want it to be on standby. I want to use OSPF for this. Miami and LA are datacenters. I want the VPN's to go into both datacenters if possible running OSPF for backups. I have a feeling this will be very tricky. I also wanted to use floating routes. Now I know I get the VPN's up and running using OSPF with no problem. Here are my questions:
But being that I am using different areas, will OSPF through the VPN work correctly? I have the Cisco PDF on setting this up but it looks like they are using the same, AREA0, in the example.
Can I get both VPN's to work with no problems? Or will it be too much of a pain?
What would you guys suggest?
Thanks.

We are implementing the same solution, and was only able to make this work using HSRP one router for the MPLS connection and one for the VPN tunnel. I opened a TAC case and the tech couldn't get it to work either. I was able to establish the Lan-2-lan tunnel but triggering the route update was the problem. We ended up pulling our ASA5505's out and putting in 1841 routers.

Can I use my Time Capsule with a point to point antenna?

We have a building about 400 feet away that I would like to install wireless cameras. Can I use a point to point antenna with our time capsule or is there a better option?

The Time Capsule is too hard to get into. You can do this but the end result will be rather messy and for an expensive unit like the TC that is a waste.
Get a unit made for this job.. you only need a WAP..

IPv6 Addressing Point to Point Links in the enterprise

For an enterprise, it doesn't seem to make sense to use Global addressing for point to point, transit-only links and loopbacks.
Link-local only addressing breaks debugging tools like traceroute, DNS, etc.
Is Unique Local the correct choice for this?
I've searched quite a bit and I've not found a lot of discussion about scope selection for point to point links. Some RFCs such as 6164 imply Global scope vs Unique Local scope usage is a preference. Most discussions of point to point addressing focus on bit length. I'm assuming this means design concerns are agnostic toward scope selection.
Is anyone aware of documentation I've missed or have any recommendations in this area?
If ULA was the correct choice, address hierarchy might look like this:
DataNetwork1 -- Router1 -- ULA.1.1 -- Link -- ULA1.2 -- Agg Router -- Core
DataNetwork2 -- Router2 -- ULA.2.1 -- Link -- ULA2.2 -- Agg Router /
DataNetwork3 -- Router3 -- ULA.3.1 -- Link -- ULA3.2 -- Agg Router /
The network core would have summarized entries for DataNetwork[1|2|3] and ULA[1|2|3]. IE, there would be a Global hierarchy and a ULA hierarchy.

Scott,
Let me break this down into some categories for you.
Address selection:
I believe that best practice is to use Global Unicast Addressing everywhere (coupled with a proper security policy at your edge). ULA was a compromise for Site Local never being properly defined and whilst it can be used in the same way as GUA I don't believe it is worth it. Irrespective of what you use (GUA or ULA), subject to your security and routing policy traceroute will work from both ends (e.g. you tracing out, someone tracing in)
Address masking:
The general rule of thumb is that you allocate /64s to eveything and then mask down to the appropriate mask for the function you are expecting (P.S. Forget everything you learnt about IPv4 address conservation). If you are using /127 masks then in theory every p2p link in your network is either a 0 (::) or a 1 (::1)
e.g.
traceroute HostB:
1     2001:1234:abcd:1::1
2     2001:1234:abcd:2::1
3     2001:1234:abcd:3::1
4     2001::4:10
The only exception to this is loopbacks, you can sequentially allocate /128s from the same /64 block
NOTE: /127 support is recent and may not be supported by some vendors, in this case use /126 masking (same as you would use /30s in IPv4)
If you have a /48 ( a normal enterise allocation) or larger then this should not be an issue ( you have access to 65536 x /64s) the only reason you would consider ULA for infrastructure numbering is because you have a small IPv6 pool. I would still argue you should get more IPv6 addresses than use ULA.
I hope this helps
Cheers

Turns out the mistake was not adding a mask to the subnet. Ex:
Router_2(config_router)# network 192.168.0.0 0.0.255.255
Router_2(config_router)# network 172.27.0.0 0.0.255.255
Doing that on both routers made the hosts capable of pinging each other.
Thanks for the tips everyone

How do I get routing data from the Map App (powered by TomTom) so I can display the point-to-point annotations (turn-by-turn navigation) without leaving my own application.

I have a tableView displaying a list of contacts from a Cloud Database. After selecting a contact, I push to a programmatically created MKMapView. Then I display the initial region (the view) that includes the users current location (starting point) and their selected destination (end point).
Now I want to display annotations (as described in the Location Awareness Programming Guide) that displays polylines which will represent the turn-by-turn navigation IN MY OWN APPLICATION, and not in the Map App currently used in IOS6.
Due to licensing and its becoming depricated in IOS 6, I do not want to get routing data from the Google Maps API. How do I get routing data from the IOS 6 Map App (powered by TomTom) so I can display the point-to-point annotations (turn-by-turn navigation) without leaving my own application?
I checked out Stack Overflow and other forums which basically left me with the impression that this is not possible. I also checked out the TomTom iPhone Mobile SDK User Guide from the TomTom Developer Portal and am still confused. It must be possible to retrieve routes, since the Map App can display turn-by-turn directions. How can I retrieve turn-by-turn data that I may display as a route within my own application?

Thanks Michael. Apologies for the slow reply I was away for a bit (holiday blitz at work and visiting family madness etc.etc.) back now, I set both options you requested to "never " and retried the CMS software with no change.
I do have progress of a sort though, as a test I took a separate test PC and put a clean install of Win7 on and loaded up the CMS software (it worked perfectly) and then took the version of ole32.dll off that machine and put it onto the computer I had built
for her (using Linux) and...
got a new error code. Darn I was so sure I had found a clever solution this time lol.
Anyway now when the CMS fails it gives me a similar error but the offending module is "ntdll.dll" sooo... I tried taking the "working" version of ntdll.dll from the test box and moving it over (making sure to back up the existing ones
first so I could put them back if needed) to her new PC and the PC would not boot.
It seems to want the original versions of a few Dynamic Link Libraries and if I could somehow give it those while not breaking Win7 it should theoretically work seeing as it no longer errors with ole32.dll.
ntdll.dll however seems necessary for Win7 to boot.
So what I am wondering now is:
Is there some way to have both versions of the DLL file in the system32 folder (bypassing the "cannot have two files with the exact same name in the same folder" thing) or rename the original DLL's something else and somehow make the CMS look for
the new named versions so the system has the updated DLL's it needs to boot/run and the CMS has the old ones it wants to run or is there someway to have a self contained install of the CMS, say on a USB flash drive and give it it's own E:/windows/system32/needed
dll's path to the files it needs?
Willing to try any other options or settings you may have come up with as well.
Thanks again for your reply and my apologies for not answering sooner.

Broadcast and point to point server in the same port

I'm trying to set up a system where I can send point to point messages via sockets to certain ips, send broadcast messages to every pc in the network, and also be able to listen for point to point messages and broadcast messages, all in the same port. I've been able to establish a point to point connection using the Socket class to send the message, and using the ServerSocket class to listen for messages, but I can't seem to get broadcasting to work.
I read somewhere that for broadcasting one should use the DatagramSocket class. The problem is i'm not sure which ip i'm supposed to specify when I send the message. Also, do I need a special listener to listen for broadcast messages, or will the ServerSocket listener work for that?
This is what I have for the broadcasting part:
String msg = myId;
DatagramSocket sendSocket;
sendSocket = new DatagramSocket(Constants.COM_PORT); // 4567
InetAddress group = InetAddress.getByName(Constants.BROADCAST_ADDR); // "192.168.1.1"
DatagramPacket dp = new DatagramPacket(msg.getBytes(), msg.getBytes().length, group, Constants.COM_PORT);
sendSocket.send(dp);
sendSocket.close();
Thanks in advance
Diego

It worth mentioning that UDP/broadcast and robust do go together easily.
- UDP does not guarantee delivery. i.e. messages can be dropped and you won't be told. Lost packets are not retransmitted either.
- UDP can fragment packets if larger than 532 bytes long.
- UDP packets can arrive out of order (though I have never seen this myself)
If your receiver is under load/busy it can miss many packets if its buffers overflow.

Calculating BPM using either Peak Detection point by point or FFT

Hi Guys
Im new to Labview and have absolutely no idea on programming and stuff. Im doing a project on Heart Rate monitor.
I'm using labview to read the analog input to an Arduino Mini. In my attached VI im using Peak Detection Point by point to calculate the BPM but it doesnt seem to work. I took references from several VIs to arrive at my VI.
My instructor told me I could try using FFT to calculate the BPM as well but Im not sure how to carry it out in Labview.
Hope you guys can help me with this.
Thanks alot!

Ok, we have some problems here.
1. The Data Bits property is the number bits for a single character that is being transmitted. You should not use that. Since you are using an Arduino, it should be sending the termination character. So just tell the VISA Read to read maximum number of bytes you expect from a single message or just some large number (like 25). The VISA Read will stop reading the port when it encounters the termination character.
2. The String Subset is not doing anything. Just remove it.
3. You should move your Wait to be outside of the case structure. As is currently written, if you are not taking readings you will use up all of your CPU.
4. You should have labels for all of your controls and indicators.
5. Your time calculation is completely wrong. You want to subtract the time of the previous peak from the current peak. I recommend you use a Feedback Node to do this.
Here's a slightly cleaned up version of your code.

XY graph : Plot point by point

hi my intention is to plot in a XY graph point by point. Meaning for eg: I want to plot a scatter plot.
First I check if the array element satisfies a certain condition (let's say if it lies between 1 to 5) if So I want to plot in red color, else I want to check another condition (let's say lies between 5 to 10) and then plot in blue color and so on.
First I check for the condition and link it to a case structure such that each case structure will contain the corresponding plot color but it doesnt seem to be working.
Kindly guide me with this.
thanks!!
Solved!
Go to Solution.

Hi Chathuri,
If you want to plot a scatter plot, you can do this by editing the properties of the XY graph. Righ-click on the X-Y Graph object and click on Properties.This will bring up the property viewer. If you then go to the Plots tab, you should see a screen similar to the one shown as an attachement. The fourth column from the left sets the display type and if you click the top diagram, you will display individual data points. I have circled this in the attached diagram. You will also need to set the tick markers to display. You can do this if you set the third column from the left.
Hope this helps,

How to make an acquired array of data work with point-by-point functions

Hello everyone,
I am working on a LabVIEW project using the Measurement Computing PCI-DAS6402/16 board. I am attempting to use point-by-point analysis with data acquired from the board, but I am having some difficulty. I am currently only able to acquire an array of data and not just a single point of data per scan. So, I was wondering if i) anybody possibly had any knowledge/experience using this particular board and getting it to be compatable with point-by-point VIs or ii) if anybody possibly knows anyway to convert an array of acquired data to work with point-by-point VIs in a hard realtime application. Thanks

Hi Pat
I just can tell you how you can use the pt-by-pt functions. As you said you have an array of data. To use the pt-by-pt functions, you need the single datapoints. So the only way is to use a loop to get the single elements and pass them to the pt-by-pt functions.
I've attache a simple example.
If this is the right way for you concerning processor and memory load, execution speed etc. I can't tell you.
Hope this helps.
