摘要
在SDN移动自组网络中,有限的控制平面的可拓展性限制了网络规模的发展,而目前的解决方案存在不同控制器间无法直接共存和接口协议效率低下的问题。为解决上述问题,本文设计了高效的、多模式、支持异构控制器协同工作的SDN控制平面东西向协议:开放性可变长协议。实验结果证明,OXP可显著降低通信开销,为SDN移动自组网络提供了高效的东西向协议,提高了SDN移动自组网的可拓展性。
The limit scalability of control plane restrict the scale of Software-defi ned Ad Hoc. The current solutionsneither coexist with different controllers nor provide hightransmission effi ciency. Thus, we propose aneffi cient West-East protocol for software defi ned Ad hoc: Open eXchange protocol(OXP), which supportsheterogeneous controllers to cooperate together. We implemented OXP on the test bed to evaluate theperformance. The result shows that OXP is a more effi cient protocol, which is more suitable for SDN inAd Hoc.
