Abstract
With rapid growth of Internet, the variety of applications is used on Internet. In order to meet all kinds of requirements, many network equipments with specific functions are widely introduced in today’s network. As Internet gets more and more complex, the network management becomes an important topic. However, offering any kind of network service and applications is based on the premise that the network is fault-free or the fault is tolerable. The most common failure is on the network equipments itself. Moreover, network equipments located at the entrance of a network play an important role in the network availability. Therefore in this thesis, we design and implement a policy-based service management system on a chassis-based platform to provide gigabit level multi-service in the entrance of a network. The purposed system architecture could provide policy-based flow routing and fault-tolerance. With flow routing, the flows could be classified to meet different service requirements. The thesis adopts the Vitesse IQ2000 Network Processor as development platform to implement the proposed system. By using the Network Processor, most work can be executed by hardware. This can reduce operating time, improve processing speed, and increase system performance. Moreover, we integrate the Network Processor-based system as a module into the chassis-based platform that is scalable for integrating the other service into the multi-service platform. Finally, experimental results prove that our system has good performance and is feasible.
