Realization of novel routing protocols for IP radio networks above 70 GHz in MPLS

In this paper, proposal for implementation of novel routing protocols for IP radio networks at frequencies above 70 GHz is described. The protocols are designed to improve network performance in the presence of the rain that has an intensity that causes link down state and/or capacity reduction of some links in the network, but network graph remains connected. New protocols, named OSPF-BP and OSPF-BN, are modifications of standard OSPF routing protocol which imply traffic sharing between main shortest path route and specially defined backup routes. It is showed that majority of novel routing protocols´ features could be achieved just with proper configuration of routers with standardized multi protocol label switching (MPLS) traffic engineering (TE) capabilities.
