Protocol Proxy for OSPF Emulation
This paper proposes a protocol proxy scheme that can emulate the Open Shortest Path First (OSPF) protocol in an effective and flexible manner. It is implemented in the authors' developed network emulator, which is used to test network controllers for IP optical network management. In the protocol scheme, OSPF protocol emulation is achieved by combining an OSPF protocol proxy (introduced here) and an OSPF peer state manager based on existing OSPF protocol software. The protocol proxy produces OSPF packets holding link state advertisements with customized extensions including MPLS and GMPLS, while the OSPF peer state manager implements neighbor establishment via the proxy.
