LOBS网络与GMPLS网络互联协议的研究
|
摘要
本论文主要探讨了LOBS网络与GMPLS网络互联融合问题中控制信令协议的设计与实现。
论文首先描述了LOBS网络与GMPLS网络互联平台中信令协议模块的设计方案。通过比较决定采用重叠模型实现LOBS网络与GMPLS网络的互联。而后着重阐述了信令协议设计中的三个重点和难点问题并分别提出了相应的解决方案。随后在OBS网络中采用的简化版OSPF和RSVP协议,不仅完成了两协议的基本功能,而且在很大程度上简化了操作和实施难度,试验证明简化版的OSPF和RSVP协议非常适宜于在类似于本试验平台的小规模网络中部署。最后通过采用客户端/服务器模型,试验平台保证了LOBS网络的边缘节点和GMPLS网络的边缘节点能够通过简单的配置信令交互完成域间自动邻居发现和LSP通路创建等工作。
既设计方案的论述之后,本论文又详细阐述了整个信令模块的实现细节。包括信令部分整体工作流程的描述和OSPF路由协议,RSVP信令协议以及OBC-GBC之间专用信令流程的实现。
This article emphasizes on the study of Interworking protocol of LOBS and GMPLS Networks.
In the second chapter, the design of interworking protocol was discussed. Firstly, through comparison, the overlay network model was adopted. Secondly, three most important key points in the design were specially pointed out and corresponding resolutions were finally proposed. Thirdly, abstracted OSPF and RSVP protocols were proposed. It was proved that these two protocols not only could meet the basic requirements but also could be accomplished much more easier than the standard ones. Fourthly, OBC and GBC adopted the clinet-server model to achieve the configuration work.
Besides of the protocol design, the details of the protocol completion was also discussed in this paper.
