Fig. 2 is that the present invention carries out the flow chart that data channel is shared.

[embodiment]

Below in conjunction with accompanying drawing the present invention is done further description.

See also Fig. 1, be system block diagram of the present invention.This system comprises channels share proxy service module, channels share service providing module, IGRS protocol stack module, security module and PERCOM peripheral communication passage.

Wherein, the function of each module is following:

IGRS protocol stack module: comprise IGRS basic agreement stack module software.In the present embodiment; Agreement between Connection Service device end and the client adopts the IGRS agreement; And being connected except that realizing through the IGRS agreement between server end and the client; Can also utilize the DLNA agreement of initiating by the tame consumer electronics industry giants of Intel, Philip, IBM, Hewlett-Packard, Microsoft etc. 17, or be master's ECHONET agreement with Japanese manufacturer.

Security service module: be responsible for safety certification, guarantee to have only legal users the visit data channels share to serve;

The channels share proxy service module: the channels share proxy service module runs on client, and it intercepts and captures the network access request from browser, and is transmitted to service end through the IGRS protocol stack module.Under the regular situation, when the user passed through the browser access Internet resources, browser is with direct and network layer, and was mutual like tcp/ip layer.And in the present invention; The channels share proxy service module is as an intermediate layer between browser and the tcp/ip layer; The network requests of can the intercepting user sending from browser; Browser is thought network layer is sent in request, and in fact this request is to have sent to channels share agency service layer.By this way, just can when reducing to greatest extent, increase the flexibility of system to the existing application modification;

The channels share service providing module: the channels share service providing module runs on service end, and this resume module is passed through the client-requested of safety verification, and it is transmitted to last PERCOM peripheral communication passage;
