Design Of The Access Platform, Based On The Npu Architecture Bypass Dual 10g Pos Shunt

Huge development of the networking conveniences the public to gain information and promotes the economy. At the same time it brings the Internet Service Providers (ISP) and Internet Service Supervisors (ISS) with more challenges. The old-time pattern of management which ignored the transmitted content has been eliminated. A network manager ought to analyze the networking effectively without influencing the existed network construct. The existing front-end of traditional bypass-analyzing system generally makes use of the system comprising routers or specialized chips to carry out the network-line access and obtainment and distribution of data. As the bone-network upgraded to 10Gbps POS (Packet over Synchronous Digital Hierarchy), the access-project of traditional bypass-analyze confronts the issues from three aspects in order to hold performance: cost, system flexibility (refers to rapidly adjust the different back-end service requirement, including 7-layer filtration etc.) and upgradeable services (for example, satisfy the needs of network protocol in future such as IPv6.).Aiming at the problems above, the essay put forward the project through analyzing the features of Network Processing Unit (NPU), integrating with requirement of the bypass-access system and concerned keep-session arithmetic of payload balance. The solution, namely Bypass Dual 10G POS Distributary's Access Platform, takes the NPU as processing core, gives a specific description of hardware construct; system function and implementation of the date transmitting plane and control managing plane; tests of part guide line of antitype-machine of the platform. At last, the solution presents the application scenes by giving some concerned cases.Via the application by NPU in the bypass-access platforms, the solution advances flexibility of the platform, boosts up the 7-layer filtration function and reduces holistic cost effectively. It helps to form the correlated solution by combining with different kinds of bypass-analyzing systems which have different application. The solution could achieve success both in social benefit and economical benefit. Also, it provides reference design for other similar platforms.
