摘要
作为新一代网络技术的一体化承载网,主要是通过构建逻辑承载网的方式来提供各种网络服务。逻辑承载网是依据柔性网络可提供的服务类型,根据用户的需求构建的虚拟专用网络。文章以满足用户业务需求为前提、以网络资源利用率为优化目标,从理论上提出面向服务提供的新型一体化承载网体系结构,分析基于该体系结构网络的构建步骤和策略,从全网的角度提出构建逻辑承载网的优化策略,从理论上对构建一体化承载网络、提高网络的服务质量进行了探讨,提供了一种新的解决思路。
Computer networks have been developing quickly under the business-oriented architecture for many years, while traditional computer network architecture cannot apply to the rapidly developing networks and the consecutive growing user＇ s demands. As a kind of new generation network technology, Universal Carrying Network provides network services by constructing logic carrying network. Logic carrying network sets up a special network based on user＇ s demands, considering service types it can provide. Aiming at meeting the demands of user＇ s business and improving the re- source usage, at first this paper theoretically develops a new service-oriented UCN （Universal Carrying Network） architecture, and then analyzes the steps and strategy to construct the network based on this architecture, finally develops the optimization strategy of logical carrying network based on the whole network to improve the resource usage. A new solution to constructing Universal Carrying Network and improving quality of network service is theoretically given in this paper.
