The transmission assembly Td disposed in the purpose fringe node, for receiving request message, the request message carries industry Business mark si, wherein the transmission assembly Td and M business plug-in unit are deployed in the purpose fringe node, the M is positive whole Number；The transmission assembly Td is also used to, and carries out the decapsulation processing of tunnel head to the request message to have been decapsulated tunnel The request message of head；Business plug-in unit dpi corresponding with the service identification si is to the request message for having decapsulated tunnel head Business logic processing is carried out to obtain the request message after business logic processing, wherein the business plug-in unit dpi is the M One of business plug-in unit in business plug-in unit.

28. communication system according to claim 27, which is characterized in that carry base in the tunnel head of the request message In the path description of the transmission path for the request message that the purpose iso-ip Internetworking protocol ISO-IP address of the request message obtains；

Wherein, the transmission assembly Td, is also used to receive the response message of the request message；Call the business plug-in unit dpi Business logic processing is carried out to obtain the response message after business logic processing to the response message；At the service logic Response message after reason carries out tunnel head encapsulation process to obtain encapsulating the response message of tunnel head；To in the transmission path The purpose fringe node upper hop node send it is described progress the encapsulation of tunnel head after response message；

Alternatively, the business plug-in unit dpi is also used to generate the response message of the request message；The transmission assembly Td is also used to Head encapsulation process in tunnel is carried out to obtain encapsulating the response message of tunnel head to the response message；To in the transmission path The purpose fringe node upper hop node send it is described progress the encapsulation of tunnel head after response message.

29. a kind of computer storage medium, which is characterized in that

The computer storage medium is stored with program, wherein include claim 1 when described program is executed by relevant device to Method described in 5 any one.

30. a kind of computer storage medium, which is characterized in that

The computer storage medium is stored with program, wherein include claim 6 when described program is executed by relevant device to Method described in 13 any one.
