Working with a small test network, we wanted to demonstrate various load-balancing scenarios with Routing Information Protocol (RIP) and Open Shortest Path First (OSPF).

Generalized Multi-Protocol Label Switching (GMPLS) is used as the control protocol for ASON, of which the routing part is mainly governed by the Open Shortest Path First (OSPF) protocol.

OSPF (open shortest path first) is a widely used dynamic routing protocol in IP networks.
