Research On Service Adaptation Node Control System In Optical Network Base On SOPC

Recently, with the network technology and broadband technology matures and the rapid development of information technology, Internet traffic has been continued explosive growth, which has caused tremendous pressure to network. So providing highly effective all-optical connection has become a research focus to cope with the dramatic increase in the volume of business and the coexistence of multiple services. And the introduction of the hierarchical networks has brought great significance to the optical transport networks with rational allocation of resources and optimization management. The control plane, which acts as the network management plane, is the hub to control the operation of the entire network. It plays an important role in joining the network management and the data processing plane. This research focus on the service adaptation node control system which is the most important part in the control plane. We start from the embedded system, which is the base of the service adaptation node control system and raises the technology of embedded Ethernet, SOPC-based hardware and software co-design techniques and some other important technologies related to service adaptation mode control system. This article will focus on these techniques to study the service adaptation node optical network control system, it will include:(1) Deeply in research of embedded real-time operating system and embedded TCP/IP protocol, realization the principle understanding of embedded Ethernet. And Study of the basic technology and design process based on SOPC software and hardware collaborative.(2) Design the overall program of service adaptation node control system according to the system functional requirements, and then put forward the detailed implementation scheme of hardware system and software system separately. We use the SOPC system replaces the pure hardware embedded platform, So we can not only make full use of the surplus resources of the FPGA chip, but also avoiding the poor reliability and stability of the pure hardware platform.(3) We design and implementation the error control function of the service adaptation node control system, Guarantee the stability and robustness of service adaptation node control system in the long run.(4) Research the optical network signaling protocol, design a dedicated message protocol according to the demand of the system. We design the message protocol as streamlined and efficient as possible under the premise of meeting the business needs of Experimental platform.(5) According to the design scheme, using Quartusâ…¡ and Niosâ…¡ IDE development environment, implement the service adaptation node control system, And through system testing, validation service adaptation node control system has meet the functional requirements of the overall scheme.
