Problems solved by technology

However, in some cases such as small packets as the main load in the network, the transmission rate of each physical network card may be far below the speed limit, so that the aggregate is far from reaching the expected bandwidth, and the bandwidth utilization may be low

Abstract

The embodiment of the invention discloses a data sending method, a data receiving method and relevant devices. The data sending method can include the steps of writing first data to be sent into a first kernel-mode physical memory space address based on a first user-mode virtual memory space address, and sending a first data sending instruction to a virtual network adapter so that the virtual network adapter can indicate N physical network adapters to read first data from the first kernel-mode physical memory space address which has a mapping relationship with the first user-mode virtual memory space address after determining K virtual network adapter queues which have one-one mapping relationships with K user-mode network adapter queues represented by K user-mode network adapter queue identifications, and sending the first data based on the K physical network adapter queues which have the one-one mapping relationships with the K virtual network adapter queues. According to the technical scheme, the improvement of the bandwidth use ratio achieved after the physical network adapters are aggregated is facilitated.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a data sending method, a data receiving method and related devices. Background technique [0002] With the rapid development of computer network bandwidth, how to quickly and completely capture network data packets in a high-speed network environment is the basis for efficient data packet forwarding and accurate analysis and processing of network packets. Due to the high price and lack of flexibility of the dedicated network card for network packet processing, it is particularly important to implement a software-based high-speed packet capture system through a common network card on a computing node (such as a server) running an operating system such as Linux. [0003] However, the bandwidth of a single ordinary network card is limited, and it is difficult to meet the requirements of the high-speed message system. In some existing technologies, multiple network cards are ...
