Generalized Multi-Protocol Label Switching (GMPLS) Signaling Extensions for the evolving G.709 Optical Transport Networks Control
暂无分享,去创建一个
Recent revisions of ITU-T Recommendation G.709 have introduced new
features for Optical Transport Networks (OTN) ODU0, ODU4, ODU2e,
ODU3e1, ODU3e2 and ODUflex. Several recent documents have proposed
ways to modify GMPLS signaling protocols to support the new OTN
features. It is important that a single solution is developed for use
in GMPLS signaling and routing protocols. This solution must address
all of the new features, must be acceptable to all equipment vendors,
and must be extensible for the evolving OTN. This document describes
the extensions to the Generalized Multi- Protocol Label Switching
(GMPLS) signaling to control the evolving Optical Transport Networks
(OTN) with new features including ODU0, ODU4, ODU2e, ODU3e1, ODU3e2
and ODUflex.
