Abstract

A message sending method is provided, which includes: obtaining route feature information of a user, and sending a request of the user, where the request is data in an Efficient Extensible Markup Language (XML) Interchange (EXI) format, and the route feature information is carried in a header of the data in the EXI format. A message processing method, a client, a router, and a message processing system are further provided. Through preceding technical solutions, a user request message is routed according to route feature information in an EXI header, thereby reducing a system overhead and improving a distribution processing efficiency.

Claims

1. A message sending method, comprising:

obtaining route feature information of a user; and

sending a request of the user, wherein the request is data in an Efficient Extensible Markup Language (XML) Interchange (EXI) format, and the route feature information is carried in a header of the data in the EXI format.

2. The message sending method according to claim 1, wherein the obtaining route feature information of a user, comprises:

obtaining the route feature information of the user according to content requested by the user to be sent;

or

obtaining the route feature information of the user according to a preset policy.

3. The message sending method according to claim 1, wherein the route feature information is carried in user defined parts of options of the header of the data in the EXI format.

4. The message sending method according to claim 1, wherein the route feature information is carried in fixed parts of the header of the data in the EXI format.

5. The message sending method according to claim 1, wherein the route feature information is carried in new option parts extended to the header of the data in the EXI format.

6. The message sending method according to claim 1, wherein before the sending a request of the user, wherein the request is data in an EXI format, further comprising:

performing EXI encoding on content requested by the user to be sent, and add the content to an EXI body; and

performing the EXI encoding on the route feature information, and add the route feature information to an EXI header, to obtain the data in the EXI format.

7. The message sending method according to claim 1, wherein the route feature information of the user comprises any one of the following information:

the type of content requested by the user to be sent, the type of the destination server, the number of the destination server, the priority of the content requested by the user to be sent, and the size of the content requested by the user to be sent.

8. A message processing method, comprising:

receiving a request from a client, wherein the request is data in an Efficient Extensible Markup Language (XML) Interchange (EXI) format;

performing decoding on a header of the data in the EXI format, to obtain route feature information; and

sending the request from the client according to the route feature information.

9. The message processing method according to claim 8, wherein the sending the request from the client according to the route feature information, comprises:

looking up a preset route table according to the route feature information, to find a destination address requested by the client; and

sending the request from the client according to the address.

10. A client, comprising:

a route feature information module, configured to obtain route feature information of a user; and

a sending module, configured to send a request of the user, wherein the request is data in an Efficient Extensible Markup Language (XML) Interchange (EXI) format, and the route feature information is carried in a header of the data in the EXI format.

11. The client according to claim 10, further comprising:

a request content encoding module, configured to perform EXI encoding on content requested by the user to be sent, and add the content to an EXI body; and

a route feature encoding module, configured to perform the EXI encoding on the route feature information, and add the route feature information to an EXI header, to obtain the data in the EXI format.

12. A router, comprising:

a receiving module, configured to receive a request from a client, wherein the request is data in an EXI format;

a decoding module, configured to perform decoding on a header of the data in the EXI format to obtain route feature information; and

a routing module, configured to send the request from the client to a corresponding destination server, according to the route feature information.

13. The router according to claim 12, wherein the routing module comprises:

a looking-up unit, configured to look up a preset route table according to the route feature information, to find a destination address requested by the client; and

a forwarding unit, configured to send the request from the client according to the destination address.

14. A message processing system, comprising at least one client, at least one destination server and a router communicated with the at least one destination server, wherein:

the client is configured to obtain route feature information of a user and send a request of the user, wherein the request is data in an Efficient Extensible Markup Language (XML) Interchange (EXI) format, and the route feature information is carried in a header of the data in the EXI format;

the router is configured to receive the request from the client, wherein the request is the data in the EXI format, perform decoding on a header of the data in the EXI format to obtain the route feature information, and send the request from the client according to the route feature information; and

the destination server is configured to receive the request sent from the router and perform processing on the request sent from the router.

15. The message processing system according to claim 14, wherein the client is specifically configured to obtain the route feature information of the user according to content requested by the user to be sent or a preset policy, and send the request of the user, wherein the request is the data in the EXI format, and the route feature information is carried in the header of the data in the EXI format;

16. The message sending system according to claim 14, wherein

the route feature information is carried in user defined parts of options of the header of the data in the EXI format;

or

the route feature information is carried in fixed parts of the header of the data in the EXI format;

or

the route feature information is carried in new option parts extended to the header of the data in the EXI format.

17. A computer-readable medium having computer executable instructions for performing a method comprising:

obtaining route feature information of a user; and

sending a request of the user, wherein the request is data in an Efficient Extensible Markup Language (XML) Interchange (EXI) format, and the route feature information is carried in a header of the data in the EXI format.

18. A computer-readable medium having computer executable instructions for performing a method comprising:

receiving a request from a client, wherein the request is data in an Efficient Extensible Markup Language (XML) Interchange (EXI) format;

performing decoding on a header of the data in the EXI format, to obtain route feature information; and

sending the request from the client according to the route feature information.
