Problems solved by technology

Because the existing network uses a centralized server, the load is relatively heavy, which will cause reliability problems (a large number of users are gathered below, once a problem occurs, it will cause a huge impact); moreover, P-CSCF (or application layer signaling agent) is isolated from RACS , the P-CSCF is usually located in the core network, and the RACS is usually located in the access network, which cannot perform signaling routing based on network policies; in addition, the access network does not involve the processing of application layer signaling, that is, all devices such as the P-CSCF are placed in the In the core network, the core network cannot finally perceive the user's location through the content in the signaling

Abstract

The invention provides network equipment and a network system. The network equipment comprises a communication interface unit for receiving and sending application layer signaling. The network equipment is characterized by comprising an application control unit. The application control unit comprises the following modules: an application function module for acquiring the media stream information of the application layer signaling received, a policy decision module for generating the request information of resource reservation according to the media information and the policy rule provided by the operator, a resource admission control module for carrying out the admission control according to the request information of resource reservation and the network resource condition and returning the admission control result to the policy decision module and the application function module. The network equipment of the embodiment of the invention can carry out the reasonable admission control management for the resource request of any application layer protocol based on the sense of the network status and can choose the appropriate path for the application layer signaling.

Description

technical field [0001] The present invention relates to the field of resource management, in particular to a network device and a network system. Background technique [0002] The SIP (Session Initiation Protocol) session initiation protocol is formulated by the IETF for multi-party multimedia communication. According to the definition of IETF RFC3261, SIP is an application layer control protocol, independent of the underlying transport protocol TCP / UDP / SCTP, used to establish, modify and terminate two-party or multi-party multimedia sessions on the IP network. The SIP protocol draws on protocols such as HTTP and SMTP, supports functions such as proxy, redirection, registration and positioning of users, and supports user mobility. By cooperating with RTP / RTCP, SDP, RTSP and other protocols and DNS, SIP supports voice, video, data, E-mail, status, IM, chat, games, etc. The SIP protocol can be transmitted over TCP or UDP. Since SIP itself has a handshake mechanism, UDP can b...
