Yes. A long list of people are publishing data that suggests this. >Is there current proposal to replace BGP as >the current EGPs on the internet. We don't yet have anything to replace it with. The Internet Research Task Force (IRTF) has published two drafts of requirement documents, written by "Team A" and "Team B". I'm on Team B. There definitely needs to be full-time research by quite a number of people to figure out alternatives. The discussion may move from the IRTF into the IETF, where a temporary area directorate might be created to focus attention. This is what was done to create IPv6. Travel budgets being tight, I'm still hoping to get to the IETF in Yokohama this summer, where some decisions about workplan may be made. Right now, there are assorted small teams exchanging ideas. > >I don't have the detail, but about one or two years back, you mentioned that >traffic engineering as it is, on the internet faced difficulties due to >basic concepts of EGPs, i.e. you cannot control traffics once it leave your >AS.. how has that change in the last 2 years ?
