Problems solved by technology
[0004] When the network device chooses to use the flow-by-flow forwarding method to forward packets, if the service packets of a certain service flow surge, it may cause some CPU cores of the network device to be busy and lose packets, while other CPU cores are idle.
When the network device chooses to use the packet-by-packet forwarding method to forward packets, because some services do not support the packet-by-packet forwarding method, packet loss and service interruption will occur.

The invention discloses a message forwarding method and device, network equipment and a storage medium, which are applied to the network equipment with a multi-core processor CPU. The method comprisesthe steps of receiving a service message; judging whether a first kernel is busy and a second kernel is idle exists in the multi-core CPU or not , wherein the first kernel and the second kernel are different kernels in the multi-core CPU; and if yes, when it is determined that the service message does not belong to the preset service, forwarding the service message in a packet-by-packet forwarding mode. According to busy or idle information of each kernel, the scheme of the message forwarding mode is intelligently selected; and the network equipment can automatically switch the forwarding modes of the message in the time periods with different flow sizes and / or in different application scenes, and can guarantee the optimal forwarding mode of the preset service, thereby guaranteeing the more intelligent and efficient load sharing, and guaranteeing the integrity and safety of the network data.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a message forwarding method, device, network equipment, and storage medium. Background technique [0002] With the rapid development of the network, the performance requirements of network equipment are getting higher and higher. Traditional network equipment has also developed from an early single-core CPU to a multi-core CPU, that is, a network equipment has multiple CPU cores working together, which greatly improves Network performance with a single network device. Currently, a multi-core CPU of a network device basically has 8, 16, 32, 48, or even more cores. [0003] Currently, network devices with multi-core CPUs use two methods to forward received service packets to CPU cores for processing: flow-by-flow forwarding and packet-by-packet forwarding. Flow-by-flow forwarding refers to using five-tuple (source IP address, source port number, destination I...
