An Introduction to DiffServ, IntServ/RSVP, MPLS and VPN
The MPLS and Traffic Engineering seminar presents the issue of traffic
engineering in IP networks. DiffServ and IntServ/RSVP are studies as an
introduction to MPLS, to which most of the seminar is dedicated. Label format
and distribution are explained, as well as RSVP-TE, CR-LDP and CSPF. At the end,
VPN related issues are studied.
