【摘要】:為了均勻電力通信網(wǎng)絡(luò)業(yè)務(wù)流量的分布并提高網(wǎng)絡(luò)吞吐量和傳輸可靠性,提出了一種基于熵的業(yè)務(wù)均勻分配算法。根據(jù)電力通信網(wǎng)具有的業(yè)務(wù)特點(diǎn)進(jìn)行業(yè)務(wù)流量分析,業(yè)務(wù)流量的分布情況體現(xiàn)了網(wǎng)絡(luò)業(yè)務(wù)運(yùn)行狀態(tài),將業(yè)務(wù)信息熵作為衡量網(wǎng)絡(luò)業(yè)務(wù)分布均勻化的指標(biāo),進(jìn)而引用信息熵作為目標(biāo)函數(shù)得出優(yōu)化全局業(yè)務(wù)路由的算法。首先將業(yè)務(wù)的時(shí)延作為約束條件,求得滿足業(yè)務(wù)需求的可用路徑集,再將業(yè)務(wù)信息熵作為優(yōu)化函數(shù),最后利用量子遺傳算法解決多約束路由問(wèn)題,在適應(yīng)度評(píng)價(jià)的過(guò)程中添加帶寬約束,控制每條業(yè)務(wù)流量路徑走向,求取使得當(dāng)前網(wǎng)絡(luò)業(yè)務(wù)信息熵值最大的業(yè)務(wù)路徑集。仿真結(jié)果顯示,在基于熵的業(yè)務(wù)均勻算法下的網(wǎng)絡(luò)業(yè)務(wù)分布相對(duì)均勻,并有效地控制了流量,實(shí)現(xiàn)了優(yōu)化網(wǎng)絡(luò)資源和均衡網(wǎng)絡(luò)負(fù)載的目的。
[Abstract]:In order to distribute the traffic of power communication network and improve the network throughput and transmission reliability. An entropy based uniform traffic allocation algorithm is proposed. Traffic flow analysis is carried out according to the characteristics of power communication network. The distribution of service traffic reflects the running state of network services. The service information entropy is taken as the index to measure the uniform distribution of network services, and then the information entropy is used as the objective function to obtain the algorithm of optimizing global traffic routing. Firstly, the delay of services is taken as the constraint condition. The available path set is obtained to meet the business requirements, and then the business information entropy is taken as the optimization function. Finally, the quantum genetic algorithm is used to solve the multi-constraint routing problem, and the bandwidth constraints are added in the process of fitness evaluation. Control the direction of each traffic path and obtain the service path set which makes the maximum entropy of current network traffic information. The simulation results show that the network traffic distribution is relatively uniform under the uniform algorithm based on entropy. And effectively control the flow, realize the goal of optimizing network resources and balancing network load.
