Abstract

Disclosed is a method for processing a SOCKET, a method and an apparatus for transmitting packet data, wherein, the method for processing a SOCKET comprises: a connection management application obtaining a SOCKET identifier corresponding to each service application, and transmitting the SOCKET identifier and a modification instruction to a TCP/IP (Transmission Control Protocol/Internet Protocol) protocol stack; the TCP/IP protocol stack searching for SOCKET file description information corresponding to the SOCKET identifier, and modifying the SOCKET file description information according to the modification instruction. After adopting the technical solution mentioned above, the IP binding operation across applications can be performed on a single-process or multi-process operating system, and the application level traffic selection of the different data connection can be performed according to intention of a user.

Claims

1. A method for processing a SOCKET, comprising:

a connection management application obtaining a SOCKET identifier corresponding to each service application, and transmitting the SOCKET identifier and a modification instruction to a TCP/IP (Transmission Control Protocol/Internet Protocol) protocol stack;

the TCP/IP protocol stack searching for SOCKET file description information corresponding to the SOCKET identifier, and modifying the SOCKET file description information according to the modification instruction.

2. The method according to claim 1, further comprising:

after obtaining the SOCKET identifier corresponding to each service application, the connection management application giving a prompt for network link information related to the service application.

3. An apparatus for processing a SOCKET, comprising a connection management application module and a TCP/IP (Transmission Control Protocol/Internet Protocol) protocol stack module, wherein,

the connection management application module is configured to obtain a SOCKET identifier corresponding to each service application, and transmit the SOCKET identifier and a modification instruction to the TCP/IP protocol stack module;

the TCP/IP protocol stack module is configured to search for SOCKET file description information corresponding to the SOCKET identifier, and modify the SOCKET file description information according to the modification instruction.

4. The apparatus according to claim 3, wherein, the connection management application module is further configured to give a prompt for network link information related to the service application after obtaining the SOCKET identifier corresponding to each service application.

5. A method for transmitting packet data, comprising:

a connection management application obtaining a SOCKET created by each service application, searching for an IP address of a specified network link which corresponds to the service application, and transmitting the SOCKET identifier, the IP address and a link modification instruction to a TCP/IP (Transmission Control Protocol/Internet Protocol) protocol stack;

the TCP/IP protocol stack searching for the SOCKET file description information corresponding to the SOCKET identifier, and modifying a source IP address in the SOCKET file description information to the IP address of the specified network link according to the link modification instruction; and

the TCP/IP protocol stack transmitting the packet data of the service application through the specified network link.

6. The method according to claim 5, further comprising:

after obtaining the SOCKET created by each service application, the connection management application giving a prompt for an option of all supported network links, and receiving one option selected by a user;

wherein the step of searching for an IP address of a specified network link which corresponds to the service application comprises;

searching for an IP address of a network link corresponding to the option according to information of the option selected by the user.

7. The method according to claim 5, wherein, the step of searching for an IP address of a specified network link which corresponds to the service application comprises:

searching for the IP address of the specified network link which corresponds to the service application according to quintuple information corresponding to the SOCKET identifier from a pre-stored correspondence relation between the quintuple information corresponding to the SOCKET identifier and the network link.

8. An apparatus for transmitting packet data, comprising a connection management application module and a TCP/IP (Transmission Control Protocol/Internet Protocol) protocol stack module, wherein,

the connection management application module is configured to obtain a SOCKET created by each service application, search for an IP address of a specified network link which corresponds to the service application, and transmit the SOCKET identifier, the IP address and a link modification instruction to the TCP/IP protocol stack;

the TCP/IP protocol stack module is configured to search for SOCKET file description information corresponding to the SOCKET identifier, and modify a source IP address in the SOCKET file description information to the IP address of the specified network link according to the link modification instruction; and

transmit the packet data of the service application through the specified network link.

9. The apparatus according to claim 8, wherein, the connection management application module is further configured to:

after a SOCKET processing module obtains the SOCKET created by a certain service application, give a prompt for an option of all network links supported by the apparatus, and search for an IP address of a network link corresponding to the option according to information of the option selected by the user.

10. The apparatus according to claim 8, further comprising a storage module, wherein,

the storage module is configured to store a correspondence relation between the quintuple information corresponding to the SOCKET identifier and the network link;

the connection management application module is configured to search for an IP address of a specified network link which corresponds to the service application by a following mode;

searching for the IP address of the specified network link which corresponds to the service application from the correspondence relation.
