摘要:

本文为构建ForCES体系结构中的转发单元FE提出了一个参考模型。该模型利用拓扑建模法来构造报文转发数据通路,形成FE模型拓扑依赖关系图。同时,还采用XML语言对FE的能力和状态、拓扑连接以及元数据等信息做出形式化描述,向CE提供动态配置和管理FE的逻辑视图,进而在模拟环境中实现CE对FE的灵活配置和管理。最后,通过初步的模拟实
验进行了验证。

Abstract:

Based on the ForCES architecture, a reference model is proposed for the Forwarding Element (FE) to provide a logic view to CE for dynamic deploymentand management. In the model,a topological approach is used to build the data path for forwarding the packets offered by FE, and a formal file in XML i s provided to CE, describing the capabilities and state information of FE, etc. Finally, the model is verified through abecedarian experiments.

Key words: FE, topological approach, LFB modeling, formal description
