Multi-layer path control

[Kohei Shiomoto <Shiomoto.Kohei@lab.ntt.co.jp>]

Hi folks,

I feel that GMPLS opens a new direction for multi-layer path network control and the topic should be addressed in the CCAMP. Traffic engineering in multi-layer networks is a promising application. I posted the following I-D on traffic engineering in multi-layer networks. Comments and feedbacks are highly appreciated.

Kind regards

This draft proposes a traffic engineering framework for multi-layer path
networks using dynamic virtual topology configuration capability of
GMPLS protocols.  The electrical label switched path is routed over the
virtual topology built on a set of optical label switched path in multi-
layer path networks.  The virtual topology is dynamically altered by
setting up or tearing down optical label switched paths.  Virtual topol-
ogy is configured in response to traffic demand change so that conges-
tion of the network is mitigated.  Utilization of label switched path is
measured at ingress node and disseminated with routing protocol
extensions for the individual node to decide whether the virtual topol-
ogy should be altered or not without centralized coordination.
