Scenario 1: LBM using a Parallel LSP When no bandwidth sharing is physically possible E.g. to go from one VC-3 to VC-4 Need to signal a parallel connection as being a “replacement” connection Parallel Connection can use different “traffic parameters” and explicit route (and thus diverse) Slightly different from the existing MPLS-TE mechanism (RSVP-TE FF and new CR-LDP Action Indicator Flag under consideration) Switchover is done at the source when everything is ready Completely independent from LCAS
