What frame relay switch is causing MCI/Worldcom such grief? The above article contains this statement: "From what we know about the disruptions in the U.S., our UUNet is not being affected because its network rides on a different platform," Wagner said.
From what I know of UUNet's frame relay network (which may be woefully
outdated knowledge) they are using Cascade/Ascend/Lucent switches. This would tend to make one suspect that the problems are associated with non-Lucent switches rather than being some unusual effect within the frame relay protocol itself. Is this another vendor related problem? If not, does it affect NNI customers of Worldcom? With the growing profile of MPLS, I suspect that more networks are planning to roll out frame relay or ATM in their core in which case the technical facts behind these events should be of great interest to many of us on this list. I am less interested in the length of time a network is down and more interested in why it was down and how other operators could avoid the same problem. -- Michael Dillon - E-mail: michael () memra com Check the website for my Internet World articles - http://www.memra.com
