一体化标识网络基于标签转发的QoS保证机制

Label-Forwarding-Based QoS Mechanism for Universal Network

一体化网络与普适服务体系是一种全新的"标识分组网络"体系结构。为保证一体化标识网络的服务质量,结合现有IP网络的服务质量保证技术,提出了一种基于标签转发的QoS保证机制。该机制引入一体化服务质量管理器,能够动态地管理域内资源,实现QoS路由;采用流标签转发机制,可实现快速交换和传输;采用接纳控制和资源预留,提高网络资源利用率。经试验证明,所提方法能够为一体化网络上承载的语音、视频等实时多媒体业务提供有效服务质量保证。

As a new architecture of identifier packet network,the universal network and pervasive service infrastructure can support varieties of services and applications in the future.In order to provide reliable QoS guarantee for services in the network,investigates QoS guarantee techniques for IP network and proposes a novel QoS guarantee mechanism for universal network.This mechanism can achieve dynamic resource management and realize QoS routing by adopting universal QoS manager in each domain;achieve fast switching and transportation using flow label forwarding technology;and improve the efficiency of resources in the network by employing admission control and resource reservation.And the experiment results confirm that this mechanism can provide QoS guarantee for real-time multimedia applications such as voices and videos effectively in the universal network.
