A bi-criteria stochastic model for restorable QoS routing in MPLS

摘要

Routing methods in modern communication networks involve the calculation of paths satisfying various technical constraints (usually QoS-Quality of Service-related constraints) and often the associated models seek to optimise simultaneously several metrics. Therefore there are potential advantages in developing multicriteria routing models in this area, depending on the features of the network functionalities and the adopted routing framework. In particular the MPLS platform for IP networks enables the implementation of advanced routing schemes, namely explicit routes satisfying QoS requirements, and is prepared for dealing with multi-path routing, including resilient routing schemes, explicitly prepared for dealing with component failures.
