Background technology
Based on the next generation network of Softswitch, be the network architecture that miscellaneous services such as voice, data and multimedia are provided for the user, have three big features: 1. opening; 2. business-driven; 3. packet-based network.Next generation network has become telecommunication network development tendency.In multiple business such as voice that flexible exchanging network provides, multimedia, their real-time requires very high, needs network to have good QoS and guarantees.Can flexible exchanging network guaranteed qos, becomes the key that can it become the following unified platform.
For example, Fig. 1 shows a kind of networking schematic diagram of flexible exchanging network, in this network, from the angle of operator, network is divided into three parts: this carrier network N1, other carrier networks N2 and two user access network N3, N4.
Comprise control appliances such as Softswitch and application server in the network N 1, and access device such as Tandem Gateway, user access networks pass.All devices all is subjected to operator's control, and communication provides QoS to guarantee mechanism by the network planning in the net.The equipment of network N 2 and network N 1 identical (part only is shown among the figure), but the QoS management strategy is inconsistent, and for network N 1, if the uncontrolled network N 1 that directly enters of the data in the network N 2, the QoS that can influence it guarantees.Comprise access devices such as IAD, IP phone and video terminal in the network N 3, do not belong to network N 1.From the angle of network N 1, these equipment are fly-by-night, if the uncontrolled network N 1 that directly enters of the data in the network N 3, the QoS that can influence it guarantees.
In current network, there is the solution of multiple QoS, as Resource Broker model, priority lifting, authentication sign etc.
