摘要
本文讨论了分布式交互式DVB-T系统(IDVB-T)中的分布式网络服务质量(NQoS)提供方法,使其能够实现可扩展和容错操作。本文描述了再生式IDVB-T基础设施的设计和总体架构,其中网络资源分配和服务分类过程在每个中间分布节点(Cell Main node CMN)的本地级别执行,为CMN到CMN NQoS提供奠定了基础。实验验证了该方法的有效性,并将测试结果与聚合和联邦NQoS提供方法进行了比较,结果表明该方法具有相似的性能,但具有更好的可扩展性和容错设计。
Distributed NQoS provision in interactive DVB-T systems
This paper discusses a Distributed Network Quality of Service (NQoS) provision approach in decentralized interactive DVB-T systems (IDVB-T), enabling for scalable and fault tolerant operation. The paper describes the design and overall architecture of a regenerative IDVB-T infrastructure, where network resource allocation and service classification processes are performed at local level within each intermediate distribution node (Cell Main Node CMN), setting the basis for a CMN-to-CMN NQoS provision. Validity of the proposed approach is experimentally verified, and the test-results are compared against the aggregated and federated NQoS provision approaches, indicating similar performance but better scalability and fault-tolerant design.
