Service flow transmission method, system and network equipment

The embodiment of the invention provides a service flow transmission method, a service flow transmission system and network equipment, and belongs to the technical field of communication. The method comprises the following steps: a virtual router receives a target request message forwarded by a virtual switch, and matches the target request message with a pre-configured service quality rule set; the virtual router sends the target request message to a virtual load balancer according to a matching result; the virtual load balancer selects a service server for the target request message according to a pre-configured load balancing rule; and the virtual load balancer sends the target request message to the virtual switch, so that the virtual switch forwards the target request message to the selected service server for service processing. According to the invention, the data processing performance of the whole business service system can be improved. 本发明实施例提供一种业务流量传输方法、系统及网络设备，属于通信技术领域。其中，方法包括：虚拟路由器接收虚拟交换机转发的目标请求
