Path based p-cycles for resilient MPLS network design

Resilient networks are those capable of continuously offering telecommunication services in the presence of network failures. New paradigms for reliable network design have been emerging and constantly improving network survivability. Failure-Independent Path-Protecting (FIPP) p-cycles are a path based extension of the well-known p-cycle concept and inherit attractive properties of ring-like recovery speed and mesh-like capacity efficiency. They are suitable for application to the Multi-Protocol Label Switching (MPLS) protocol that is widely used in Next Generation Networks, in that it provides shared, failure independent, end-to-end protection to whole working paths. We consider two basic models: known as FIPP-SCP and FIPP-DRS respectively and this is followed by an introduction to a Joint Capacity Allocation design that is based on the FIPP-SCP model, which we assert is more appropriate for use in MPLS networks. The network design is referred to as the MFIPP-JCA model and involves three specific cases.
