An Experimental GMPLS-based Wavelength Reservation Protocol for Flooding Global Wavelength Information in Uni-Ring-Based MAN (original) (raw)

IFIP International Federation for Information Processing

The accelerating growth of Internet traffic, together with its bursty traffic pattern is specially motivating the research on not only high-bandwidth but also dynamic metropolitan networks based upon recent advances in optical networking technologies such as R-OADM and OXC. The dynamism of the wavelength-routed networks can be achieved by means of a distributed control plane (i.e signalling for wavelength reservation and routing for dissemination of topology and optical resource state), which can be based in GMPLS. The objective of this paper is to propose a GMPLS-based signalling protocol which allows to have a global wavelength resource information without any routing protocol when provisioning bidirectional connections in uni-ring-based MAN. Performance evaluation has been carried in a GMPLS test-bed composed of Linux routers named ADRENALINE.
