Abstract


Network system is the integration of multiple Internet resources with a huge system, such as distance education network, we have fully the company decentralized office network use cases are typical of the network system development into practice, network systems The building has been engaged in the use of the Internet to widely distributed resources together into a logical whole, integrated application services, and information sharing. Now widely carried out in virtual organizations eventually realize resource sharing and collaboration in the virtual environment, and information sharing. Network society and social networking has become the vanguard of the information construction. As one of the pillars of the social networks, cable television networks are booming momentum from traditional cable to cable transmission; developed from a one-way cable television to a two-way broadband HFC interactive network;, both as a large, the transmission speed, the transmission quality is high, the popularity of a wide range of modern mass media, and as a set of television programs. Voice, computer information in one of the new role, to provide multi-faceted services for the community. Mode of data network operators from initial access service providers (ISPs) (providing the user to connect the country special network services), the transition to the current value-added service providers ICP (only provide online content services) period of prosperity. With the network is increasingly being accepted by the community and use NSP (network service provider), the concept will become the mainstream of the business operators. NSP provides a full range of networking solutions for businesses and individuals, without users concerned about issues such as how to connect and how to get the content, and do not even have to buy equipment. Operators full use of their network resources to get the most out of the service, but also the user the easiest way to obtain comprehensive network services and strategies. In recent years, the construction of the network system and use development, we still find the IP network technology, applications, multimedia, IP multicast / multicast IP video network services competing to emerge, may make private network original Some business impact, bandwidth bottlenecks caused by network congestion, and seriously affect the smooth progress of the work, the network system, the biggest problem is network congestion, which has almost become the bottleneck of the constraints of network development and application. There are many ways to solve the congestion in the network system, which is the most basic method for the optimization of the algorithm. In this paper, under the framework of a new network protocol design study route optimization algorithms, and network topology model can solve the problem of network congestion control, and later found through simulation feasible, and therefore has important implications for network congestion control research. The main work of this thesis are: 1. Based on overview and analysis of network congestion control, network routing, network topology model design and research; 2, on the basis of the analysis of QoS and QoS routing QoS routing algorithm, network routing optimization, provides the foundation for the prevention and control of network congestion; given system design to achieve its simulation and performance analysis. Simulation results show that the optimization algorithm can achieve control of network congestion, improve network performance, congestion prevention purposes.
