MPLS TE HOT-STANDBY
Overview
Hot-standby is the important function of MPLS traffic engineering.
It strengthens the function of RSVP TE sub-system. Hot-standby
is a kind of mechanism of redundancy link protection. It creates
one protection route for every piece of protection lsp and provides
protection ability for whole route.
Hot-standby can solve the failure problems about link, node, multi-
link and multi-node in the complex network. Compared with tra-
ditional IGP handling method, hot-standby can switch the packet
from invalid lsp to standby lsp, which reduces the loss of packets
gradually. Compared with FRR which only can provide local protec-
tion, the end-to-end protection effect supported by hot-standby is
better.
