T3 backbone stability
by Mark Knopper 13 Feb '92

13 Feb '92

Dave, I have summarized and enclosed below our trouble tickets written over the last 5 days for the T3 network. The only problem that affected more than one peer site was a crash of CNSS40 at Cleveland yesterday afternoon due to a hardware problem. While a CNSS crash of this type would not normally cause users loss of connectivity due to backbone redundancy, this crash did result in connectivity loss since the Ann Arbor interconnect E131 which is homed int o the Cleveland POP became reachable via the safety net T1 links only. The interconnect gateway was switched over to Houston during this time. This resulted in a 25 minute outage of the interconnect. The last T3 router crash we had was several weeks ago and the last hardware induced crash was several months ago. While this is an undesirable event, I suspect that SURAnet's use of the T3 backbone may actually reduce your dependency on the interconnect gateways. We have installed new software (build 64 and new rcp_routed) across the T3 system during the last two weeks with additional performance and reliability enhancements including improved aggregation of interior routing updates, faster convergence time, and reduced CPU utilization. Operationally we have begun the on-call schedule for the new NNAF engineering group which has resulted in some more detailed NSR reports on these scheduled and unscheduled events. This event coupled with the numerous scheduled software installations may have given you the false impression that there was an increase in problems. My general conclusion is that while we have still have some problems with the current T3 adapter technology, this has been manageable and the T3 backbone is still very reliable. We will cautiously monitor the network reliability for changes as we add additional traffic to the T3 system. The T 1 network is not nearly as reliable and we are busy working on those problems. Mark Peer network router problems: 18410 - SURAnet sura7.sura.net 18429 - BARRnet equipment move 18441 - Pittsburgh power failure Backbone router hardware problems: 18423 - cisco serial interface, Xlink (Germany) 18426 - cnss40 spare t3 card removed from backplane to reduce frequency of black links.

Could someone at Merit summarize some of the recent outages if there have been trends, or could some of the other midlevels provide us with some insight as to how (in)stability has affected your connections? We are going with the emerging standard of send T3 stuff to the T3 and T1 stuff to the T1, explicitly importing T3 routes and defaulting everything else to the T1. thanks, dave o'leary SURAnet

I can tell you right now that the NSFNET T3 backbone has come a long, long way since last October. (Mark Knopper and his gang must have been in hell back then!) The reliablity has been extremely good. I will admit that the traffic probably isn't taking full advantage of the speed of the T3 pipes right now, but the upgrade of the T3 cards in the NSSes will hopefully improve that situation. The throughput is still definitely higher than a T1 though... So, are there people still having problems with the T3 backbone? I have failed to see any evidence that "the NSFnet is pretty bad," at least worse than a CIX T1 connections. --zawada __
