GMPLS last call

Hello,

I have one question on GMPLS contention solution.

Contention resolution has been extensively discussed for bi-directional
LSPs. However, it is not clear how contention would be resolved in a
network with both uni-directional and bi-directional LSPs.

Although the immediate applications for mixing uni-directional and
bi-directional LSPs in the same network is not really clear, a
consistent state machine is still required so as not to preclude this in

the future.

Has there been any consideration on this issue? If so, can someone
please explain the rules when contention occurs between a
uni-directional LSP and a bi-directional LSP.

Thanks,

-- Guanghzhi Li
