Vadim, Your response is unrelated to the message I replied to, which asked about the link state algorithm that Cascade uses. As far as I know, nobody has announced which set of MCI Wordlcom's switches were responsible for their outage. Since MCI Worldcom uses multiple types in their network, statements like "goes as predicted - complexity bites" is irresponsible at best, even if it is later determined the Cascade switches were actually the cause of the outage.

This pretty much goes as predicted - complexity bites. Watch for more.

What happened to the KISS principle?

On top of OSPF, there is a protocol which is responsible for actually setting up the connections according to specific constraints (e.g. bandwidth, QoS level). Again, this is similar to the work now being done in working groups responsible for CR-LDP and RSVP. Cascade released its version in 1993, and has been refining it ever since.
