Method and equipment for transmitting data packet by multiple network ports

Abstract

The embodiment of the invention discloses a method and equipment for transmitting data packets by a plurality of network interfaces. The method comprises the following steps: whether a virtual network interface needs to refresh corresponding relation between target values corresponding to physical network interfaces and target values of the data packets is judged; when the virtual network interface does not need to refresh the corresponding relation, all the physical network interfaces are traversed, and the target values corresponding to the physical network interfaces are matched with the target values of the data packets; and when the matching succeeds, the successfully matched physical network interfaces send the data packets. Through matching the target values corresponding to the physical network interfaces with the target values of the data packets, and using the successfully matched physical network interfaces to send the data packets, the disorder of the data packet is reduced, namely the method and the equipment reduce the transmission of invalid data so as to reduce the occupancy and consumption of a CPU; moreover, the method and the equipment increase the bandwidth of the virtual network interface under the condition of binding multi-network interface.

Description

technical field [0001] The embodiment of the present invention relates to the technical field of communication, and in particular to a method and device for sending data packets through multiple network ports. Background technique [0002] Communication or IT (Information Technology, information technology) system devices usually have multiple physical network ports. In order to improve bandwidth and link backup, multiple physical network ports are often bound into one virtual network port for use. However, the bandwidth of the bound virtual network port is always much lower than the sum of the bandwidths of each physical network port in the case of non-binding. How to select the physical network port under the bound virtual network port to send data packets directly affects the bandwidth of the virtual network port and the performance of the entire system. [0003] In the existing technology, when multiple physical network ports are bound as one virtual network port to sen...

Problems solved by technology

[0005] Since the data packets sent to the same target may be sent through different physical network ports, there will be more out-of-order data packets reaching the same target, and the bandwidth of the virtual network port is therefore low; due to the out-of-order data packets, the The retransmission of out-of-order data packets and the increase of selective acknowledgment processing generated by processing out-of-order data packets lead to a high CPU and other system resource usage on the device side.
