At CTIA, Acme Packet announced the deployment of its Open Session Routing (OSR) architecture and products, as well as an ecosystem of companies, for delivering trusted SIP-based interactive communication within and between mobile, fixed-line and transit networks. Acme says its Net-Net Session Router and OSR ecosystem members' products and services are operational in several tier-one service provider networks around the world.
OSR is designed to simplify core and inter-network session routing and reduce capital and operational expenses, as service providers continue to migrate to and further refine their next generation networks. Acme Packet's OSR solution includes the Net-Net Session Router (SR), a session routing proxy, working in conjunction with routing database products and services from OSR ecosystem members. The complementary product vendors and service providers offer centralized routing databases and database provisioning tools for dynamic route selection; using these databases, dynamic routing decisions within the core IP network and to the PSTN and other IP networks may be made using a wide selection of parameters.
As SIP-session routing becomes more complex, existing session-stateful methods of routing run into scaling problems, requiring a dynamic, real-time routing decision for each individual session for multiple sources and destinations within a network. Add in all the variations of SIP signaling elements that could get involved including wireless mobile switching centers connected TDM-based 2G/3G networks, multi-service security gateways, session border controllers, class 5 soft switches, IMS service core elements, and peering interconnections--not pretty. Enabling each element to make routing decisions also increases capital costs, since additional hardware processing power is required by each element.
Using OSR, Acme's Net-Net SR session routing proxy centralizes and consolidates control, reducing hardware cost and overhead on each transaction. The SR can also support static, localized routing decisions using provisioned policy rules and local route tables that can scale to a few million routes.
