The Design And Implementation Of Resource Scheduling Module In Network Virtualization Management Platform

Recently, the continuous increase of network load triggers the rethinking of how to improve the utilization of network resources. Besides,diverse network protocols and network architectures: promote the rapid development of the network. However, the current network architecture limited in flexibility and isolation, seriously blocked the innovation and development of the network. Network virtualization technology allows the construction of isolated virtual networks on the basis of sharing the underlying infrastructures. And it resolved the traditional network architecture's limitation in flexibility and isolation. Besides, For any network virtualization environment, they have to be managed and maintained. And the difficulty of resource scheduling increases with the increasing of network size and network structure's complexity.This paper focuses on the design and implementation of resource scheduling module to provide resource management service for network virtualized environment. It can also verify the key technology of network resource scheduling, such as scheduling algorithm and scheduling strategy.Firstly, we introduce the network virtualization environment and analyze the new characteristics brought by the network virtualization technology.Then, we analyze the resource scheduling problem in network virtualized environment. Furtherly, the resource management demands are analyzed from the two kinds of resources and one kind of relations involved in the resource scheduling problem. And we conclude the overall resource management demands. And then from the three main business scenarios to analyze the detailed functional demands. After the demands analysis, the database relations of the resource scheduling module are designed. The algorithms in three typical business scenarios are introduced in detail.Finally, on the basis of analysis of the module to achieve detail functions.
