Abstract

The invention relates to a bandwidth resource distribution system. The bandwidth resource distribution system comprises a priority grading strategy storage module, a data packet classifier, a data packet processor and a residual bandwidth estimation module, wherein the data packet classifier reads a priority grading strategy from the priority grading strategy storage module and classifies network data packets which are transmitted from the outside world and are processed through a network protocol stack, the classified network data packets are transmitted into the data packet processor, the data packet processor processes the network data packets according to an estimation result of the residual bandwidth estimation module, so that it is guaranteed that the data packet with the high priority is processed preferentially, and the network data packets are finally distributed to corresponding external applications. According to the bandwidth resource distribution system, the access bandwidth and the reversed bandwidth of the system do not need to be assumed in advance, fine granularity scheduling of network data can be conducted according to the priorities, and the network service can be provided for services with lower priorities by means of the residual bandwidth on the premise that the application with the high priority can obtain the bandwidth resources as many as possible.

Description

technical field [0001] The invention relates to an embedded system, in particular to a bandwidth resource allocation system and method. Background technique [0002] With the comprehensive advancement of "triple play", various network services are constantly emerging, which promotes the development of embedded terminals capable of carrying converged network services. Embedded terminals with network access capabilities and supporting various network services have received scientific research. , operating agencies and production departments. [0003] Various network services, especially some streaming media services or download services, require a large amount of network bandwidth resources. Although the user access bandwidth has been greatly improved in recent years, it is still stretched for so many applications with high demands on network resources. Embedded terminals mostly use Linux platform or Android platform for development. The Linux operating system adopts the st...
