Please note that Internet2 becomes another portion of the Internet which needs more than destination based routing. We expect within a gigapop that the physical topology of a gigapop will be relatively stable. Topological changes should be signal through the switching and routing technology. Please note that ingress and egress points for the MLPS tag switching may change as routers fail or the policy which ISP serves a campus changes. 3.First Router at the entrance to the network does the authentication to the remote site.
Traffic is buffered while the query is made to a Server from the router.
The router upon receiving the authorization to start data, forwards data on to the gigapop. As ingress and egress routers for each campus changes, the topology will adapt to the changes. Ingres and egress points for a large campus may be across 5-20 routers. Small campuses may only have 1-2 routers. The routers will need to load share the premium traffic to provide optimum service.
