SOFTWARE DEFINED NETWORK SYSTEM FOR PORT FAILURE DETECTION

The present invention relates to a software defined network system 100 that comprises a first network node 101 that comprises at least one virtual communication port 102. The system 100 further comprises a second network node 103 that comprises at least another virtual communication port 104, wherein the first network node 101 and the second network node 103 are configured to exchange data over their virtual communication ports 102, 104. The system 100 further comprises a flow control entity 105 that is locally arranged between the first network node 101 and the second network node 103, wherein the flow control entity 105 is configured to generate a matching flow 106 used for virtual port failure detection. 本发明涉及软件定义网络系统100，包括第网络节点101，其包括至少个虚拟通信端口102。所述系统100还包括第二网络节点103，其包括至少另个虚拟通信端口104，其中，所述第网络节点101和所述第二网络节点103用于通过其虚拟通信端口102和104交换数据。所述系统100还包括流控制实体105，本地置于所述第网络节点101和所述第二网络节点103之间，其中，所述流控制实体105用于生成用于虚拟端口故障检测的匹配流106。
