●Project Description
■VeriSign has developed a SIP and ENUM-based centralized routing directory, called VeriSign® Network Routing Directory (NRD).This engine is based on VeriSign‘s Advanced Transaction Lookup And Signaling (ATLASSM) platform - the same platform that runs the .com/.net registries on the internet.
■The NRD is logically layered upon a service provider‘s core network as a registry that enables the centralization of inter- and intra-domain route discovery.NRD may function as a common interconnect registry and as a central routing server to discover the location of endpoints.
■Equipped with SIP and ENUM interfaces, the NRD is capable of simultaneously functioning as a SIP Proxy Server, Redirect Server or SIP/ENUM Registry.Through callouts to network elements, both internal and external to the core network, NRD supports interoperability between the SIP and ENUM protocols.
■Testing Technologies (now Spirent) provided VeriSign with a solution for testing protocol compliance of the NRD product that includes SIP standards.This solution contains a fully standardized conformance test suite with over 600 ready-to-use test cases.
