The SessionEngine2000 is placed at the edge of the IP network to help build a service-based intelligent network that guarantees network security and QoS. It also implements the traversal of signaling and media streams on the NAT or firewall. The SessionEngine2000 also supports interconnecting between NGN networks and can act as C-BGF in IMS.
