WSON Network Protocol Testing Platform Building

With the development of WDM network technology and network application, the user through the management plane alone is very difficult to meet the cyber source and service scheduling maintenance requirements, the industry is to advocate the introduction of ASON intelligent optical network control plane in the traditional[1]. WSON(Wavelength Switched Optical Network) is automatically switched optical network which based on WDM transmission network[2], mainly to solve the following problems: wave division network automatic discovery of fiber and wavelength; damage model based routing; online wavelength routing.With the WSON standardization, a series of WSON test network platform appeared. In this paper, the design of the PCEP network protocol testing platform based on RFC5440 and RFC6163 standard document. The use of ARM development board as the PCE side, PCC by Windows PC. Using QT as a development tool, through the intuitive UI interface shows the working mode of PCEP protocol. Through the test results verify the feasibility of the PCEP agreement, scientific, little redundancy, high efficiency. To provide experimental basis for further research on the realization of WSON network.1. According to the data structure and PCEP workflow which described in the RFC5440 document,completed the statement.h source file.2. Reference RFC6163 document which describes the WSON network architecture, completed the test platform. Involved in the development of embedded QT test platform design, has completed the QT embedded development environment. The final implementation of QT program successfully transplanted to ARM development board.3. According to the PCEP protocol’s working process, completed the program design of PCC terminal and PCE terminal, and finally move the PCE terminal into ARM development board, and realized PCEP protocol. According to the UI interface and the console output information,observed the PCEP protocol working process, and analyzed the test results. Finally, reference the PCEP protocol design mind,designed the communication protocol in application layer, realized the P2 P communication.
