Description

Network flow automatic mixed running test method, system, terminal and storage medium
Technical Field
The invention relates to the technical field of network testing, in particular to a method, a system, a terminal and a storage medium for automatically testing mixed running of network flow.
Background
RDMA is an abbreviation of Remote Direct Memory Access, meaning Remote Direct data Access, colloquially can be regarded as a Remote DMA technology, and RDMA generated to solve delay of server-side data processing in network transmission allows a user-mode application program to directly read or write a Remote Memory without kernel intervention and Memory copy. The method does not transmit data on the network through an OS kernel and a TCP/IP protocol stack, so that the data transmission method has very low delay and high CPU utilization rate. This technique both increases bandwidth and reduces delay, jitter and CPU consumption.
Most network applications are developed based on a TCP/IP network protocol stack, the protocol has a characteristic of forwarding lost data packets, and when a network is bad, the network needs to continuously confirm and retransmit, and communication based on the protocols is slow, so that performance is greatly influenced. In contrast, IB uses a trust-based, flow-control mechanism to ensure the integrity of the connection with very little loss of packets.
However, with the rapid development of internet technology, especially in recent years, there are more and more high-performance technologies and artificial intelligence devices, and the demand for network technology is also more and more diversified. The network protocol technology is used as a network universal language, the requirement for ensuring smooth communication among network devices is higher and higher, and a plurality of network protocols can be required to run simultaneously in the same network. If multiple protocols exist in the same network, the resource occupation can be influenced mutually, and a mode for allocating network protocol occupation ratio is needed for the resource occupation.
A plurality of existing network test methods are used for carrying out a race test or an iperf network pressure test independently, so that the existing network test methods cannot test whether bandwidth occupation is caused between different protocols, and further cannot evaluate network performance comprehensively.
