Real-time task admission control method of shared resource network

Abstract

The invention discloses a control method for real time task admission for shared resource network. The invention is to provide a control method for network admitting real time task so that the admission is not only performed but satisfy the demand for time limit. The technical scheme: first establishing real time task admission controller for network composed of resource status statistical analysis module, real time task application pretreatment module, real time judging module and admission and decision-making module. The resource status statistical analysis module gathers, calculates and analyzes the network resource status; the real time task application pretreatment module pretreats the real time task application; the real time task judging module judges necessary and sufficient condition of executable task; if several window time periods satisfies necessary and sufficient condition, then window time period of maximum executable probability is selected; the admission and decision-making module makes decision for real time task and forms notice for admission or not. The invention can performs network admission control for real time task.

Description

technical field [0001] The invention relates to a method for admission control of real-time tasks in a shared resource network. Background technique [0002] The new era is the era of information network. People are in the information network environment, and the collection, transmission, processing and application of relevant information cannot be separated from the network. The execution process of completing these information tasks has a certain time limit requirement, that is to say, the execution of time-required tasks (real-time tasks) is ubiquitous. If the execution of real-time tasks is timed out, the execution will be meaningless, and even cause serious loss of tasks. However, the resource availability of the shared resource network is not fixed and changes anytime and anywhere. It cannot guarantee the resource usage required during the execution of real-time tasks, that is, it cannot ensure that real-time tasks are completed on time. This is a pair of prominent c...

Problems solved by technology

[0004] In short, the network flow control method can not solve the demand of the network to accept real-time tasks. So far, there is no open literature related to the admission control scheme of real-time tasks. How to determine how the network accepts real-time tasks according to the requirements of real-time tasks is a technical issue concerned by those skilled in the art
