Analysis of OSPF MANET IETF-64 Scenarios

The IETF OSPF WG is evaluating two proposals for OSPF MANET extensions. At IETF-64, Stan Ratliff from Cisco Systems presented data that showed Overlapping Relays with Smart Peering yielded lower overhead than MANET Designated Routers in sparse, highly mobile networks. Since that meeting, we have worked with Cisco to try to replicate and explain the reported results. The IETF-64 results have since been retracted by Cisco. This memo goes into further detail to explain the discrepancies and to present more current results for the scenarios of interest.
