IMISA：interconnection mechanism for IP subnet and SDN subnet in autonomous system

  • Online:2014-10-25 Published:2014-12-16

摘要： SDN网络与传统IP网络的互联机制是当前学术界的研究热点，但现有解决方案并不能适用于所有应用场景。为此提出了一个基于OSPF协议的IMISA架构，在一个包含 SDN 子网（基于OpenFlow）和IP子网的自治系统范围内，通过给SDN控制器添加一个OSPF路由模块，利用OSPF协议交换各自的网络信息，最终实现了2种网络的互联。

Abstract: The interconnection mechanism for SDN network and traditional IP network has been the focus in academia, but the current solution can’t be used in every condition. To solve this problem, an architecture named IMISA was proposed which was based on the OSPF protocol. In the autonomous system with both SDN subnet (based on OpenFlow) and IP subnet, an OSPF routing module was added to the SDN controller to help exchanging network informations and finally the networks can communicate with each other.
