摘要： According to an example, a VEPA switch may receive a message and a determination may be made as to whether a Datapath of the VEPA switch includes a flow table entry for forwarding the message. In response to a determination that the VEPA switch does not include a flow table entry for forwarding the message, the message may be forwarded to a SDN controller through a SDN protocol that is to construct the flow table entry for forwarding the message according to information contained in the message, in which the constructed flow table entry identifies an egress port of the VEPA switch for forwarding the message. The VEPA switch may also obtain the constructed flow table entry from the SDN controller and forward the message via the egress port identified in the obtained flow table entry.

摘要： A controller of a virtual switch system receives an uplink packet forwarded by a SDN switch hosted on a server from a VM (virtual machine) hosted on the server. The controller determines an outgoing interface from at least two uplink interfaces on the SDN switch respectively corresponding to aggregated member ports of a physical switch by using an aggregation algorithm according to the uplink packet. The controller generates a first flow table entry and sends the first flow table entry to the SDN switch, wherein the first flow table entry is to instruct the SDN switch to forward a received uplink packet to the physical switch through the outgoing interface.
摘要翻译：虚拟交换机系统的控制器从托管在服务器上的VM（虚拟机）接收由托管在服务器上的SDN交换机转发的上行链路分组。控制器通过使用根据上行链路分组的聚合算法，从分别对应于物理交换机的聚合成员端口的SDN交换机上的至少两个上行链路接口确定出局接口。所述控制器生成第一流表条目，并将所述第一流表条目发送到所述SDN交换机，其中所述第一流表条目是指示所述SDN交换机通过所述输出接口将接收到的上行链路分组转发到所述物理交换机。
