摘要： 在NGI主干网主要形式IP/DWDM光Internet中,如何提高其容错能力同时改善其QoS(quality of service)组播性能是需要解决的主要问题,容错QoS组播路由是行之有效的解决方法之一.采用预防式容错策略和双树保护模式,基于蚁群算法,设计了一种容错QoS组播路由模式.以最小化光树故障率为目标,通过建立满足QoS约束的主光树和备份光树来达到容错目的.仿真研究表明,该模式是可行和有效的,具有较好的性能.

Abstract: IP (Internet protocol)/DWDM (dense wavelength division multiplexing) optical Internet is one of the mainstream networking techniques as backbone for next generation Internet (NGI), and how to improve its fault tolerance capability and quality of service (QoS) multicast provision becomes critical. In this respect, the fault-tolerant QoS multicast routing is one of the effective solutions. A scheme of preventive fault-tolerant QoS multicast routing is therefore proposed on the basis of ant colony algorithm and dual-tree protection mode. Aiming at minimizing the fault rate of light tree, a principle and standby light tree are set up to meet the requirement of restriction on QoS for fault tolerance. Simulation results show that the proposed scheme is both feasible and effective with better performance.
