Abstract
The present invention discloses a bandwidth combined middleware system based on application layer protocol, which comprises an upper connection management module, a request management module, a remote connection management module and a running data statistical analysis module. The upper connection management module is communicated with an upper application. The request management module caches an original request, the dividing request based on the running data and application layer protocol is dispatched to be distributed on different network interfaces. A respond management module caches different network interfaces to the sub-response, according to the scheduling policy combined response, and submits to the upper connection management module. The remote connection management module sends the request to a remote server, receives the feedback data, and sends to the respond management module. The running data statistical analysis module counts the speed and latency of the data transmission, thereby providing the running data for the scheduling policy. The present invention from the point of the view of the application layer protocol can break down tasks and conveniently deploys on the mobile device, in order to achieve the purpose of the bandwidth combined.
