	att_abstract={{Open Shortest Path First (OSPF), a link state routing protocol, is a  popular interior gateway protocol (IGP) in the Internet. Wide spread  deployment and years of experience running the protocol have motivated  continuous improvements in its operation as the nature and demands of the  routing infrastructures have changed. Modern routing domains need to  maintain a very high level of service availability. Hence, OSPF needs to  achieve fast convergence to topology changes. Also, the ever-growing size  of routing domains, and possible presence of wireless mobile adhoc network  (MANET) components, requires highly scalable operation on part of OSPF to  avoid routing instability. Recent years have seen significant efforts  aimed at improving OSPF?s convergence speed as well as scalability and  extending OSPF to achieve seamless integration of mobile adhoc networks  with conventional wired networks. In this paper, we present a  comprehensive survey of these efforts. }},
