Monitoring SIP Service Availability in IPv4/IPv6 Hybrid Networks

With the increasing deployment of IPv6, IPv6-based SIP applications draw more attention from service providers. To date, most work on SIP operations and management (OAM) is undertaken on IPv4 networks. In this paper we present a framework called MoSA for monitoring SIP service availability in heterogeneous IPv4/IPv6 networks. We also investigate the fault tolerance issue of our approach analytically. A prototype has been implemented in Providence University for validation.
