Ethernet over WDM and SDH

How do we manage ethernet circuits over WDM and SDH transmission network? What all OAM tools are available for managing and diasnosis of these circuits.

EoSDH is the term used for transporting ethernet frames over a SDH transmission network.If you can remember SDH, one way this can be achieved is using Virtual Concatanation. Here, n x VC12s are concatanated to get the required speed. ex: if n=5, the speed is 10Mbps.(VC12=2Mbps).(i.e Ethernet frames are put inside the VC12 container and transported.)The SDH equipment will give the customer a normal RJ45 Ethernet interface and in the back end, the no. of VC12s corresponding to the Ethernet speed is concataneted and transported over a STM-1/4/16/64. On the other side, the concatnated VC12s are identified and the Ethernet farmes inside the VC12s are mapped on to the Ethernet interface.
If you see the end to end circuit, you will see ethernet. so normal tools used for Ethernet troubleshooting can be used. SDH troubleshooting tools can be used to test the transport part. There may be tools which can troubleshoot moare than this.

  • Ethernet over STM-1 (SDH)

    We wish to extend our Ethernet connection from our POP to a remote site over a leased STM-1 circuit. A lot of suppliers had been suggesting different hardware like RAD RIC-155Ge (http://www.rad.com/10/Gigabit_Ethernet_over_STM_1_OC_3_NTU/2486/#), etc. We wish to know if Cisco has cost-effective low-end hardware that can do similar solution, as we prefer to standardised with our Cisco hardwares, if yes, kindly name the hardware, part number.

    We are doing something very similiar with the 15310-MA. Its not the cheapest solution but it had the features and support that we wanted. The box comes in a SONET version and SDH version.
    We are using it to transport 2 gige's over an oc48 wave in the US and internationally we use it to transport 1 gige over stm4 leased lines (a gige interface plus the 15310-MA was still cheaper than buying the stm-4 line card for the platform we use.)
    Since you are doing SDH, the 15305 might work just as well and it should be more comparable in price to the RAD.

  • IP over Firewire AND Ethernet  connected cluster?

    Does anyone have any experience with IP over Firewire and Qmaster? What I'm trying to do (for now) is to have a file server connected to a bunch of Firewire HD's, then that connected to two other macs via IP over Firewire, and all that be a cluster.
    The file server is the controller. Or I want it to be at least. Connected to this cluster are two workstations, connected to the file server via Ethernet.
    So it's File Server with several external Firewire HD's connected to it with the video data. Connected to this file server are two macs via IP over Firewire which will be services only nodes. Connected to ALL of this over ethernet are two editing workstations. Qadmin can't seem to see the two mac nodes connected via IP over Firewire.
    The problem is that Qadminstrator can't see the two macs connected to the file server via IP over Firewire. I'm wondering if for some reason data can't go from Ethernet to IP over Firewire and back again.
    Any tips or suggestions? I'm just about out of ideas for now.

    I was also NOT ABLE to use both nodes connected in a MIX of ETHERNET and FIREWIREover IP.
    I WAS able to get a 4 x NODE cluster working using SHAKE & COMPRESSOR/QMASTER using all GbE EThernet - I went out and bought a cheap 8 x PORT ethernet GbE hub and all my problems went away.
    HEre's what I had initially and what I did and it DIDN'T work consistently..:
    Hardware Initially:
    • g5 QUAD and 2 x MBP Dual Core 15's + 1 x MBPDC 17inch.
    • G5 QUAD GBE1 connected to #1 x MBPDC 15 on its EN0 with cable
    • G5 QUAD GBE2 connected to #2 x MBPDC 15 on its EN0 with cable
    • G5 QUAD FW0 connected to 1 x MBPDC 17 on its FW1 with 6 pin FW cable
    • G5 QUAD is set as CONTROLLER+SERVICES
    • MBPDC's are all SERVICES ONLY.
    • thus 3 x SUBNETS
    SETUP#1- problem symptoms
    • via QMASTERADMIN - G5 CONTROLLER could see MBPDC 17 and ONE of the MBP15;s but not all of them.
    •tries various configs on each FW and EN0 for boths FW and EN paths.. never consistent view..
    • removed some FW disks from FW400 path that were attached to CONTROLLER G5 host ... could then see ALL as a MIX of THERNET and FW. (Same happens using FW800 - although avoided this because of sperious DISK issues wth external FW800 disks on G5 QUAD).
    • created cluster (not a quick cluster)- sent simple long I-FRAME based DV-PAL to smaller DVPAL) codec test to compressor and set the CLUSTER to the QMASTER on I defined.
    • set QMASTER controller sys pref to use ALL NETWORK PATHS and disbaled the AIRPORT subnets on each MACHINE)
    • PROBLEM was only G5(controller+services) and TWO of the services nodes (MBPDC's) were processing - NEVER all three! It didn't seem to matter what IP path was onnected (EN or FW).
    • - all the above was a NO go waster of time. (aggh)
    so..
    HARDWARE SET UP #2 and what worked first time!
    • purchased 1 x GBE Ethernet hub (8xport) w/P/supply and four 1m ethernet cables
    • g5 QUAD and 2 x MBP Dual Core 15's + 1 x MBPDC 17inch.
    • G5 QUAD GBE1 connected to GBE HUB
    • #1 x MBPDC 15 on its EN0 with cable to GBE HUB
    • #2 x MBPDC 15 on its EN0 with cable to GBE HUB
    • #1 x MBPDC 17 on its EN0 with cable to GBE HUB
    • G5 QUAD is set as CONTROLLER+SERVICES
    • MBPDC's are all SERVICES ONLY.
    • thus 1 x SUBNET....!
    WORKS EVERY TIME First time
    • all machines work to render or transcode.
    • for SHAKE RENDERING, each CPU has a process.. so there seems to be as many as (4 x 1)+2 + 2 + 2 rendering processes at any one time.
    • less for COMPRESSOR as one per HOST (4 in my case)
    Also.. in QMASTERADMIN - always:
    • have the SOURCE and TAGET disk volumes|directories ou need MOUNTED (NFS works for me) and
    • set to NEVER COPY.
    • set QMASTER sys prefs/Advanced/"USe NEtwork Interface = EN0 (or whatever one you want to use. 'd imagine that a FW hub would also do the job (IPoFW).... but for me I had all free ETHERNETs NICS so I used them.
    • oh .. enable all your airports NICS.. .. in the above QMASTER wont use this subnet.
    This speeds the WORKFLOW up enormously because the source material does not have to be COPIED to each host (well I think that what it means).
    So the solution in my case was to have ALL the HOSTS on a SINGLE subnet..
    works for me.
    hope that helps

  • IP over Firewire and ethernet at the same time?

    Is it possible to use both IP over Firewire and ethernet at the same time?
    I want to use my TB hard drive attached to one Mac via Firewire 800 to backup another Mac also attached to the same drive via Firewire 800. I can only mount the drive on one machine at a time so I need to share it out to the other Mac. It works great if I set it up to do strait IP over Firewire, with static IPs, but that means I can't connect to the internet because my ethernet connection on both machines becomes the secondary connection method. Similarly, if ethernet is primary then I can't connect via Firewire. Is there a way to set it up so the Macs will know which method to use depending on the IP address?
    I am using 10.5.1 on both machines.
    G5, 1.8 GHz, 15.GB RAM
    MBP, 2.4 GHz, 4GB RAM
    Thanks!

    Certainly.
    In the network control panel I set Built-in FireWire to the top of the service order list, followed by Built-in Ethernet.
    Next, I set Built-in FireWire to Configure Manually with the address 192.168.1.xxx and the Subnet Mask to 255.255.255.xxx, making sure the Subnet Mask is set the same on both machines and that the IP address is different on both machines and different from the Built-in Ethernet addresses.
    I applied the settings, turned on Sharing on both machines, then mounted whatever shared drives I needed by connecting to the other machine using the FireWire IP address.
    Now I am able to share drives using FireWire 800 - which works great when used with Time Machine - and still use my normal ethernet to surf, etc..

  • Ethernet over Mains solution??

    Hi All, at the moment my desktop PC is hardwired into the router but due to building work that needs to change, at least temporarily. So I’m thinking about Ethernet over Mains adaptors. While I’m doing it I would really like an adaptor by the TV. So I need three devices, one for the router, one for the TV and one for the desktop.
    I know that these things don’t share surge adaptors and a few other things and I’m not quite sure about putting one on a standard extension lead, so I’m looking for adaptors with pass through mains.
    If it makes a difference I already have a Devolo dLan 500 AVtriple+ on the way from Amazon that I ordered thinking it was a triple pack, not a single triple adaptor but £60+ I was expecting to get the solution for that not a single device. Also I don’t need them to be wireless and I only get 5mbps broadband and if I need a high volume transfer between devices, which is rare, I would be ok plugging into the router which is a home hub 2.
    Having already messed up I am starting my research again but thought I would ask here in case somebody has already solved this or has any advice.
    Thanks for any help.

    Hi Thompson,
    I have just set up a powerline network, using devolo devices.
    So, basically you want to plug your router into a network device, so your internet connection can be shared remotely by your PC and your TV/Sky using ethernet cables? Devolo do three pack setups, in the following guises - the second option having powerline pass through connectors...
    You could go for either this:
    Devolo dLAN 500 Duo Network Kit
    or this (power pass through):
    Devolo dLAN 500 Duo Plus Network Kit
    I am only stating devolo as I have knowledge of them, and are a piece of cake to set up - literally plug in and away you go, you don't even have to bother with the software that comes with them to monitor the network if you don't want to, although it is worth it as it will auto detect the firmware on the devices and let you know if there are updates available. 
    Devolos support seems pretty good as well, I am currently in the middle of a very extensive email exchange with their support team in Germany because i emailed them purely enquiring why I couldn't see a device on an old laptop using their software.They have been very helpful so far.
    Dare I say it I would stick with the 500mbps as devolo no longer produces the 200 versions, although are still available from various outlets.
    You could buy another make, getting a two pack and a third single adaptor, but I don't think there will be much difference in price when all told. At least with the above packs they are all in one box.
    For additional information, I don't find these drop off in terms of speed that much. I have a device plugged in upstairs which is connected to my router, then I have a 500Av Triple + Wireless downstairs, into which is linked a slingbox and my sky box, and a wii connected wirelessly. The transfer speed between the two devices shows 494mbs, so a drop off of 6mbs. I also have an older 200 Av in another room, which shows a transfer speed of around 178mbs.
    Hope the above helps.

  • Ethernet over Firewire - possible?

    Say you have a gigabit ethernet port on a gigabit network... is there some piece of hardware, router, anything which would let you get to the network via a firewire port?
    I ask because I am working on a Powerbook with a broken ethernet port which needs access to a gigibit network. Since FW800 is comparable in speed and is capable of IP sharing, is there any way to use it to connect to a network?
    Thanks!
    Rey

    Hi Rey, I have networked an iBook and a PC via Firewire so in my humble opinion I think it'd be possible,have a look here.
    http://developer.apple.com/devicedrivers/firewire/ipoverfirewire.html
    "Customers can immediately enable IP over FireWire and then connect two or more Macintosh systems by FireWire for file sharing, Internet sharing, or the use of any other IP-based service".http://docs.info.apple.com/article.html?path=Mac/10.4/en/mh1845.html I'll have a bit more of a look around and get back to you.

  • Direct ethernet bridging g4 and macbook

    well i posted this on the using tiger forum and got no replies, now i see the networking forum here...
    i want to connect my old 2nd gen g4 to the macbook via ethernet. I have a x over cable and it looks like i may need it as i believe the g4 to be over 4 yrs old...
    I tried just hooking up the 2 comps and hoped i would get immediate access but that is not the case. So how exactly do i set up the network? I like the idea of being able to daisy chain the internet to my g4 since it has no wifi and my macbook is recieving wifi. It looks like this would be possible but the OS tells me that it may interrupt flow from the isp. I am not sure how this will actually come in to play...
    thanks for the help.

  • Ethernet over coax question

    I have a coax cable running from the front house to the back house and want to connect my router to the iMac back there that serves up music and movies etc to the rest of the house. It's currently connected via wifi, but there are dropouts etc.
    I've been pointed to a few different devices that can run ethernet over coax, such as this one:
    http://www.netsys-direct.com/proddet...NH-310C&cat=27
    there are a variety of them, and they all seem to say they have speeds in the 100mps to at the most 500 mps. My questions is this. How fast are current Airport and Ethernet speeds? I know they speak of Gigabit wireless, so does that mean 1000mps and up?
    If I'm currently using wireless in this case, do you think switching to coax would slow things down a lot, or would it work ok?
    thanks!

    802.11g aka "wireless-g" has a maximum theoretical speed of 54 megabits/second.
    802.11n "wireless-n", has a maximum theoretical speed of 300 megabits/second, but to attain that it requires near-perfect conditions. It's normal to observe less than half that in actual use.
    These vary according to many environmental phenomena that influence radio propagation. Observed speeds tend to be considerably less. "Gigabit Ethernet" isn't so influenced, but may also be less than 1000 Mb/s due to other network factors.

  • Sample Configuration For Ethernet over MPLS.

    I am looking for a sample configuration and scenario for the Ethernet over MPLS.I would appreciate if I get some explaination with it.How the LDP is configured for the directed sessions (as per Martini draft) and the auto discovery (as per kompella draft) with respect to Ethernet over MPLS.Cam anyone help me in this ?

    Here's a sample EoMPLS configuration on the PE routers:
    R1:
    interface Loopback0
    ip address 1.1.1.1 255.255.255.255
    interface Ethernet0/0.10
    encapsulation dot1Q 10
    ! 10 = vcid must match the vcid configured on the other side
    mpls l2transport route 2.2.2.2 10
    R2:
    interface Loopback0
    ip address 2.2.2.2 255.255.255.255
    interface Ethernet0/0.10
    encapsulation dot1Q 10
    mpls l2transport route 1.1.1.1 10
    The LDP directed session will be setup automatically by the router when the xconnect statement is configured.
    Cisco IOS doesn't support the Kompella Draft.

  • HT204371 Airport Express via ethernet to router, and then use Airplay?

    I am having what seems like an unusually difficult time accomplishing the following:
    I have an Airport Express that I wish to connect to my router using an ethernet connection.  My purpose for using the AE is solely to use Airplay (using iphones, ipads) to play powered speakers.
    I seem to have no problem configuring the AE to act over WIFI to achieve this task - but instead I want to have the AE connection via ethernet, and not over WIFI, because I have experienced cut-outs in playing music when the AE is connected to my existing network over WIFI and I'm hoping that the ethernet connection would eliminate this.
    Can someone please post the proper settings using Airport Utility?  I have Utility version 6.1.
    Thanks.

    Sure, here you go.
    Make the Express look like this:
    If you also want the Express to serve as an additional access point (optional) set its Wireless Mode to "Create a wireless network" and provide the exact same Wireless Network Name and security settings as your existing router's wireless network.
