Gf8516 Core Router Reliability And Implementation

As an essential part of social infrastructure, the computer network is highly signified as to its reliability and stability. However, its operation is directly determined by the reliability of core router, the key equipment to the network system.This paper begins with an introduction of the architecture of high performance core router GF8561 and an analysis of the basic principle of the reliability theory concerning computer systems. Then, a system whose overall capability is superior to that of its components is established on the basis of redundancy technique drawn from reliability theory. Combined with features of the network equipments, the integrity of key components' redundancy configuration design and high-efficient technique for fault management as the principle of core router's reliability design is deduced.We have applied 1+1 redundancy configuration design to control processor and switch processor, the key components of core router GF8516, whose dynamic redundancy is further realized through a combination with techniques for fault management. This paper reports on technical problems in the process of redundancy design and fault management and proposes feasible solutions.The fifth chapter deals with prediction and estimation about the usability of core router GF8516. So far, the application of the aforementioned technique to GF8516 reliability design produces satisfying results. The last part of the paper offers suggestions for further research.
