SDN-Based WAN Optimization: PCE Implementation in Multi-Domain MPLS Networks Supported By BGP-LS

摘要

In order to provide efficient and flexible resource management and path set-up in high-speed MPLS/GMPLS networks, the PCE (Path Computation Element) architecture was proposed by IETF. Implementation of a central module for the path set-up enables network operators to run path establishment operations for applications with explicitly defined objective functions and QoS requirements.
