TG, Congratulations on selection of your post re Alteon as one of the cool posts of the day. You have a much better understanding of internet architecture than I do so your posts frequently clarify articles which I have read.
Pathnet is in the news today for their good earnings and also because they obtained a large line of credit from NT to build out their optical network. About a week ago, I encountered this statement from Pathnet in an article by Jim re the Bay acquisition. He refers to bring QoS down the lambda level. What does this mean? How will it help Nortel
market its optical products? Gary is always talking about how provisioning of services, not bandwidth, is what is important. Would this be an example of Nortel provisioning a service (QoS) rather than just bandwidth? Would this make a big difference to carriers and enterprises with their critical mission applications? Here is the quote:
"The other part is Nortel's focus on leadership in optical networking, which is fine with some of its customers. Pathnet, a "carrier's carrier" in Reston, Va., says the company has some optical IP trials under way that will dispel any notion of Nortel not being an IP company.
Nortel has a method for binding Multi-protocol Label Switching, which is used for engineering traffic
through IP and ATM networks, directly to dense wave division multiplexing gear that will drive quality of service down to the lambda level, and may be years ahead of competitors, says Gerry Sharp, Pathnet's chief technology officer. He says Nortel's technique alleviates the need to convert wavelengths to electrical impulses and back again."
