由于通用多协议标签交换(GMPLS)技术可以实现IP与光网络的无缝融合,IP/MPLS光网络结构已成为新一代骨干传输网络的发展趋势。同时,由于光网络中各个波长的高速传输速率,生存性是一个非常重要的问题,近年来一直受到人们的研究。因此,在新一代基于GMPLS的网络中,研究多层生存算法是非常必要的。本文综合评述了现有的多层网络生存算法,分析了现有研究的不足。本文在总结前人研究成果的基础上,展望了设计高效生存算法的挑战,并提出了新的解决方案,以更好地指导未来研究人员在多层网络中的工作。
The structure of IP/MPLS over optical networks has become the trend for new generation backbone transport networks since the technology of general multi-protocol label switching (GMPLS) can realize the seamless converage between IP and optical networks. At the same time, due to the high-speed transmission rate of each wavelength in optical networks, survivability is a very important issue and has been studied all through these years. Therefore, in new generation GMPLS based networks, it is very necessary to investigate the multi-layer survivable algorithms. In this paper, we comprehensively review the existing survivable algorithms in multi-layer networks and analyze the shortages of current researches. Based on previous studies, we prospect challenges and propose new solutions of designing efficient survivable algorithms to well guide the future work of researchers in multi-layer networks.
