Patent number: 8902731Abstract: A method for binding physical network ports for network communications creates in an application layer virtual ports that correspond to virtual network cards. Each virtual port is capable of being bound in the application layer with other created virtual ports. Multiple physical network ports, which need to be bound, are added to the created virtual ports. To receive or transmit a packet, one or more available physical network ports are selected according to a configured mode for receiving or transmitting the packet. If the configured mode is a server load balancing mode, a physical network port that corresponds to a quintuple of the packet is identified, and the packet is received or transmitted through the identified physical network port. When no corresponding physical port is found, a physical network port with minimum traffic is selected for receiving or transmitting the packet.Type: GrantFiled: December 11, 2012Date of Patent: December 2, 2014Assignee: Huawei Technologies Co., Ltd.Inventors: Yungang Zeng, Lin Peng, Zhongjun Zhang
