The Super Packet Transport Network Interface And Implementation Of Survivability Design

Increasing demand of data business transport already led to today’s bloated network. Once the demand changes, it needs to modify the configuration of the corresponding network equipment, which is quite complicated. Under this circumstance, scholars have come up with the concept of SDN in recent years, core idea of which is the separation of software and hardware. Network equipment will be controlled by the centralized controller rather than rely on the underlying network equipment. For operators, to replace current network equipment with SDN equipment, such fees and complicated process are unbearable to them.Therefore, the S-PTN network was put forward by the industry. Its concept is the combination of PTN network and SDN. S-PTN network not only has the EMS management platform, but also a new controller to control the S-PTN network equipment. Aiming at how to select north and south in S-PTN network interface and network survivability problem, this article, combining with a some large enterprise cooperation project, deals with the command of the interface, writes test software function to test S-PTN network interface command and proposes p-Cycle algorithm to protect the S-PTN network.This article first describes the S-PTN network technology research and development background, and then introduces relevant technology which S-PTN network needs to use and integration of the S-PTN technology system. Then it describes realization and protection of S-PTN network structure, including the design of the north and south interface, etc. In order to do the test for design of the interface command, software testing capabilities, the operation of the software functions and the test result was developed on the basis of the RestClient. Finally, it explains the S-PTN network survivability thoroughly, as well as the specific design scheme and implementation.As a practical application new network system framework, module division needs to be done. In this article, message process goes through the entire system module, focuses on the north and south interface framework design, and describes design of the north to the interface information. As to S-PTN network protection research, this article points out the openflow linear and circular protection technology.To test the interface command, this article designs lots of functions to test commands, and an algorithm to contrast information before command and that of after. This function can meet the needs of practical engineering. The last chapter studies the S-PTN network survivability, which recalls the protection research above, further studies p-Cycle protection technology of S-PTN. In order to get more excellent performance p circle, this article proposes p circle algorithm based on S-PTN network structure, which has the certain innovation significance to improve the utilization rate of network and the dynamic adaptation.
