Selective Aggregated Session Control with QoS Provisioning for GMPLS Networks

摘要

Carrier networks are gradually adopting a network model that consists of MPLS (Multiprotocol Label Switching) capable routers (GMPLS (Generalized Multiprotocol Label Switching) in the nearest future) and OXCs (Optical Crossconect) interconnected by high bandwidth WDM (Wavelength-division Multiplexing) links for transporting IP and Ethernet traffic. Globalization drives the quest for end-to-end QoS (Quality of Service) guarantees over different carrier networks. [1]. GMPLS is the proposed control plane solution for the next generation optical networking. GMPLS differs from the traditional MPLS with the added switching capabilities for lambdas and fibers, as well for time slots and packets. GMPLS makes the first step towards the integration of data and optical network architectures and significantly reduces the operational costs with easier network management and operation [2].
