可编程网络强调了对控制平面和转发平面的明确分离的需要。IETF ForCES协议允许控制元件连接到逻辑上分离的转发元件。ASPNET IST项目依赖于动态服务部署，这需要控制和/或转发平面中的路由器可编程性。此外，为了缩短控制元素的实现和部署时间，需要简单的更高级别的API来保护这些元素不受ForCES协议和模型细节的影响。本文提出了一种ForCES CE网关（ForCEG）架构，满足这些要求，并映射Web服务接口的ForCES消息，同时检查命令的有效性，以确保路由器状态的一致性。
Programmable networks have accentuated the need for a clear separation of the control and forwarding planes. The IETF ForCES protocol allows control elements to be connected to logically separated forwarding elements. The FlexiNET IST project relies on dynamic service deployment, which requires router programmability in the control and/or forwarding planes. Moreover, to shorten the implementation and deployment time of control elements, there is a need for simple higher-level APIs that shield such elements from ForCES protocol and model details. This paper proposes a ForCES CE Gateway (ForCEG) architecture that fulfills these requirements and maps Web Service interfaces to ForCES messages while checking the validity of commands to ensure consistency of the router state.
