摘要

Multiprotocol Label Switching (MPLS) offers a data-transportation mechanism with a wide-range of alternatives towards the varying, complicated networking procedures and serves as a reliable broad-band technique. While it enhanced the performance of packet forwarding by the use of fast label-switching, however; among the issues that come with the inherited connection-oriented architecture of MPLS are reliability and fault-tolerance. Failure management is one of the fundamental instruments that allow network operators to provide communication services that are much more reliable than the individual network components (nodes and links). In this study, we present a multi-objective, fault tolerant model for MPLS network design problems utilizing a Software Defined Networks (SDN) paradigm by introducing a Bicriteria Direct Algorithm known as Maximum Flow under Minimum Cost algorithm model. This paradigm uses the OpenFlow control management plane to design a survivable model in MPLS that will reroute traffic along optimal paths in the case of link failures. This implementation maintains and ensures a continuous network functionality that aims to resolve the shortcomings of the typical inherited connection-oriented design of MPLS networks. This approach achieves faster recovery time compared to traditional MPLS networks, while attaining optimal Fast Re-Routing technique following link or node failure scenarios.
