Proposal for Implementation of Novel Routing Protocols for IP Radio Networks above 70 GHz in MPLS

Abstract

In this paper, a proposal for implementation of novel routing protocols for IP radio networks at frequencies above 70 GHz is described. The protocols are designed to improve a network performance in the presence of the rain that has an intensity that causes a link down state and/or capacity reduction of some links in the network, but a network graph remains connected. New protocols, named OSPF-BPI and OSPF-BNI, are modifications of standard OSPF routing protocol which imply traffic sharing between the main shortest path route and specially defined backup routes. It is shown that the majority of novel routing protocols' features can be achieved just with a proper configuration of routers with standardized multi protocol label switching (MPLS) traffic engineering (TE) capabilities. For both types of backup routes attention is paid to avoid an additional unavailability due to equipment failure. The same MTTR time is kept for the same IP network when no protection mechanism are applied.
