Design And Implementation Of Routing Subsystem Based On WLAN AC

With the rapid development of mobile Internet, the users’demand for mobile high-speed data access is becoming higher and higher. Except in the2G/3G era, WLAN is also the primary means of traffic offload in the4G era. At present, the AC with IP switching function is the main device of WLAN network. Routing subsystem as a core module in AC has new requirements in efficiency, stability and fast data forwarding.Design and implementation of routing subsystem of this paper is to estimate and analyze comparison of the original AC architecture and existing AC architecture.By in-depthly analyses on the current status of the devebpment of AC and implementation of routing subsystem of the current AC architecture, it puts forward some design proposals from the high expansibility, high information processing efficiency, fast forwarding of user data, the efficiency of synchronization of neighbor table and routing information synchronization etc. The solution settles the following issues:(1) increase the data traffic of users;(2) improve the efficiency of users’data forwarding;(3) reduce maintenance costs;(4) Bring more convenience to user configuration.Based on the discussion of the necessity and implementation design of routing subsystem in AC of WLAN network, this article has analyzed routing protocols and development needs and the overall design of route subsystem, and implemented the design of each module of the route subsystem, including the design implementation of user configuration module and routing update module, proposed a design of combination linux kernel protocol stack and Quagga architecture to implement AC routing subsystem. Subsequently, taking the design and implementation of a route subsystem of a company as an example, the thesis has put forward an actual implementation proposal to the overall design of route subsystem, the design of user configuration module and the design of routing update module. Through the simulated environment experiments and tests, this paper verified the static routing, the dynamic routing and the function of the effective neighbor table and including best routing entry routing information synchronized to the switch chip. At last, with the help of Sprient performance testing equipment, according to RFC2544performance testing programs and standards, this article In terms of Influencing AC performance compares and analyzes the route subsystem which designed in this paper and in the original design scheme.
