Class Of Service

LSP’s as TE tunnels (FA Concept)

Optical CoS (LSP Multiplexing)

Traffic Engineering

Virtual Private Networks

GMPLS - (XXX or BGP ?)/GVPN

MPLS - BGP/VPN

The challenge is how to extend the MPLS-TE Protocol suite to achieve these functions in the optical domain (estimation in ‘00: 2 years - today a minimum of 1 additional year is expected to consolidate 2 first steps)

MPLS - GMPLS Convergence

Not “classical” IP or IETF topics

Competing w/ IP QoS Approach

But the problem is related to BGP

Legacy Transmission

Initial Situation at the IETF
