Embodiment Construction

[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] In the monitoring business of network communication, the problem of private network traversal mainly involves the following two aspects: the network communication between the client and the platform in the public network, and the communication between clients located in different private networks. Regarding the communication between the client and the platform server, because for most of the routers and gateways in the private network, all access must be initiated from the private network, and the access from the inside to the outside initiated from the private network is generally not allowed. Restrictions, and if no special settings are made, access to internal devices from outside the private network is prohibited; regarding communication b...

Abstract

The invention discloses a method, a network device and a server used for realizing private network traversal in monitoring service. The method includes the following steps: receiving the link keep-alive information sent by a client through the network device in the private network at fixed time so as to keep the smoothness of the link between the client; acquiring the address and the port number carried by a link layer from the link keep-alive information, and saving the address and the port number as link information communicating with the client; according to the link information, encapsulating the information data to be sent to the client and sending the information data packet to the client through the network device. The method, the server and the network device are suitable for various networking conditions and can be modified for normal use in time in the case of upgrade of the network or change of the access way, without additionally increasing or changing the network device or the server.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a method, network equipment and server for realizing private network traversal in monitoring services. Background technique [0002] With the development of network technology, monitoring services based on IP networks are gradually popularized and developed rapidly. In the multimedia system of network communication, C / S (client / server) architecture is usually adopted. The server is responsible for billing, data storage, media stream forwarding, etc., and the client directly provides multimedia services to customers, including video, audio, etc. etc. The main business of monitoring products is the data flow of video and audio. In recent years, due to the development of the telecommunications industry and the increase of network access methods, it is difficult for this type of end-to-end network service to avoid the problem of private network traversal. [0003] The...
