Openflow流表的匹配字段详解
WebO Openflow é um padrão em desenvolvimento para a administração de Redes LAN e WAN com foco em equipamentos comerciais como Switches, Roteadores, Access Points, etc. WebOpenFlow flows are mapped to filter terms, and OpenFlow controller requests to add, delete, and modify flows result in the addition, deletion, or modification of terms in the filter. When the OpenFlow controller sends a flow modification request, the flow entry match condition for the ingress port determines which logical interface filter is ...

WebOpenFlow controller can program via the OpenFlow-Switch protocol. A TTP represents the flow processing capabilities of an OpenFlow Logical Switch (OFLS). In declaring support … WebOpenFlow explicitly specifies forwarding actions. Thus, a flow with an empty set of actions does not forward packets anywhere, causing them to be dropped. You can specify an empty set of actions with actions= on the ovs-ofctl command line. For example: $ ovs-ofctl add-flow br0 priority=65535,actions=.
