Wavelength Routing Algorithm of All Optical Network Based on Traffic Engineering

General multi-protocol label switching （GMPLS） based on traffic engineering is one of the possible methods to implement all-optical network. This method implements the network with IP technique and guarantees the quality of service with traffic engineering. Based on the establishment of selecting schemes of optical path and methods of traffic calculation, the wavelength routing algorithm of all-optical network based on traffic engineering is presented by combining with prior route of shortest path and traffic engineering, the algorithm procedures are given, and the actual examples are introduced as well as the analysis on simulation calculation. This research results have certain significance for the achievement of optical switching technique of all-optical network.     

Fault-Tolerant Multistage Interconnection Network

In this paper, a new fault-tolerant Banyan (FTB) network design is proposed. The rules to add extra hardware and links to the regular Banyan network in order to get the new FTB network are presented. The work includes a modular design for a new 2×2 switch element that can be configured in different well-defined modes. In case an error occurs in the function of a switch in the FTB network, the switch can be bypassed and other switch in the network replaces its role. The most attractive feature of the new design is that it can maintain the original (regular) Banyan topology in the presence of faults. Consequently, the system performance will not be affected due to the occurrence of tolerable faults in the interconnection network. This feature makes our design different from all fault-tolerant designs. Moreover, multiple faults can be tolerated in the proposed FTB network. The FTB network will be very powerful in safety critical systems and applications where error can lead to catastrophic events.     

利用DWDM实现核心网络的光网络互联

光网络互联实现了综合ＩＰ、ＡＴＭ、ＳＯＮＥＴ／ＳＤＨ和ＤＷＤＭ技术的低成本网络。ＤＷＤＭ技术彻底改变了核心网络,在ＤＷＤＭ配置的第二阶段,ＩＰ路由器和ＡＴＭ设备直接连接到ＤＷＤＭ,省去了ＳＯＮＥＴ／ＤＳＨ和ＡＴＭ,降低了成本,简化了扩容。光网络互联多数利用了现有标准,但新技术、新网络元素的引入同多带来了互操作问题,因此必须建立开放的ＤＷＤＭ系统,这也将推动光网络互联标准的发展。
