Abstract


In today's times, many disciplines are booming, is one of the computer network, the network quality of service (QoS) is an important direction in the field of computer networking research. As we all know, the problem of network quality of service, in the final analysis, is insufficient bandwidth brought. Solve their most effective way is to fully increase the network bandwidth to exceed the application requirements. However, the increase in bandwidth is being affected by the cost of network construction time factors. Therefore, a feasible way to solve the problem is to use the current effective bandwidth and the adoption of new technologies to solve, such as QoS routing algorithm. For QoS routing algorithm, and ultimately to improve the quality of network services. Factors restricting the network quality of service, there are several aspects, therefore, how to select the appropriate constraint conditions for optimal construction algorithm, how to fully satisfy the constraint conditions, that is, the focus of research directions problem to be solved. During a specific theory, combined with the thinking of some of the existing algorithms, and introduces the concept of a congestion parameter used to characterize the situation of network congestion, and on this basis to build a new routing algorithm. The algorithm thinking, is the introduction of the congestion parameters. \The problems to be solved, such as the storage system, and how by optimizing the system run more good, and thus save costs, reduce redundancy, improve efficiency. In this paper, the congestion constraint QoS routing algorithm thinking, specified materials library modules for the platform, automated warehouse logistics training center of excellence Institute of Shandong specify the library when multi-tasking multi-material, warehouse run analog computer network congestion. Incorporated herein by QoS routing algorithm building thinking the same introduction of a congestion parameter to build a new out of the library algorithms to improve multi-tasking multi-material specified library \Innovation of this paper is to: build a constrained QoS routing algorithm based on the congestion, and through its network simulation, concluded that: the algorithm to find an optimal path in the case of network congestion, meet the better network quality of service requirements. On this basis, the idea of ??congestion constraint extension of automated warehouse for the Shandong Institute of excellence the specified materials out of the library module, and also the introduction of the congestion parameter concept to build a new algorithm, and proved by experiments: the introduction of the new algorithm in a certain degree of optimization of the operational status of the module, thereby improving the system of \
