Embodiment Construction

[0032] The present invention will now be further described with reference to the drawings.

[0033] reference figure 1 , The embedded bandwidth resource allocation system of the present invention includes: a priority division strategy storage module, a data packet classifier, a data packet processor, and a remaining bandwidth estimation module; wherein, the data packet classifier can start from the priority The division strategy storage module reads the priority division strategy, and classifies the network data packets transmitted from the outside and processed by the network protocol stack, and the classified network data packets are transmitted to the data packet processor. The processor processes the network data packet according to the estimation result of the remaining bandwidth estimation module to ensure that the high-priority data packet is processed first, and the network data packet is finally allocated to the corresponding application program.

Abstract

The present invention relates to a bandwidth resource allocation system, comprising a priority division policy storage module, a data packet classifier, a data packet processor, and a remaining bandwidth estimation module; wherein, the data packet classifier reads the priority from the priority division policy storage module Divide the strategy, and classify the network data packets that are transmitted from the outside and processed by the network protocol stack. The classified network data packets are transmitted to the data packet processor, and the data packet processor is based on the remaining bandwidth estimation module. The estimation result processes the network data packets to ensure that the high-priority data packets are processed first, and the network data packets are finally distributed to the corresponding external applications. The present invention does not need to presuppose the access bandwidth size and reserved bandwidth of the system in advance, and can perform fine-grained scheduling on network data according to priority, and use the remaining bandwidth on the premise of obtaining the maximum possible bandwidth resources for high-priority applications with lower priority Level business provides network services.

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 "three networks", various network services continue to emerge, which promotes the development of embedded terminals that can carry converged network services. Embedded terminals with network access capabilities and support for various network services have received scientific research , The attention of operating agencies and production departments. [0003] Various network services, especially some streaming media services or download services, require a lot of network bandwidth resources. Although user access bandwidth has been greatly improved in recent years, it still appears to be stretched for so many applications with high demands on network resources. Embedded terminals are mostly developed on Linux platform or Android platform. Linux operating system uses FCFS (First Co...
