Message processing method of virtual network, electronic equipment and storage medium

Abstract

The embodiment of the invention relates to the technical field of communication, and discloses a message processing method of a virtual network, electronic equipment and a storage medium. In the application, the message processing method applied to a virtual network of a message sending end comprises the following steps: after a to-be-forwarded UDP message is obtained on a virtual switch, judging whether the to-be-forwarded UDP message needs to be fragmented; if the UDP message to be forwarded needs to be fragmented, performing fragmentation processing on the UDP message to be forwarded in the mbuf memory cache through a data plane development suite running on the virtual switch; and forwarding the UDP message after the fragmentation processing. Through the above means, the fragmentation problem of the UDP message including the VXLAN message is realized on the virtual switch, and the virtual switch on the computing node can support the UDP message fragmentation unloading function, so that the virtual machine can start UDP unloading, and the performance consumption of the virtual machine is reduced.

Description

technical field [0001] The embodiments of the present application relate to the field of communication technologies, and in particular, to a packet processing method of a virtual network, an electronic device, and a storage medium. Background technique [0002] With the rapid development of the Internet and the rapid rise of the cloud industry, in order to support diversified network functions, the infrastructure network gradually tends to integrate architectures based on general-purpose computing platforms or modular computing platforms, that is, cloud computing platforms are used to virtualize network functions. change. At present, on the Openstack-based cloud computing platform, due to the continuous expansion of cloud computing, the tenant isolation technology based on Virtual Local Area Network (VLAN) in the past is facing more and more problems, including the limitation of the number of VLANs. (There are only 4094 available VLANs), and IP subnet-based zoning limits te...

Problems solved by technology

On the DPDK state OVS, all messages do not go through the kernel protocol stack, and are only processed on the user state OVS. Therefore, for VXLAN messages, a header is simply encapsulated and sent. For the OVS of the layer-2 forwarding device , packet fragmentation will not be performed, resulting in some packets being discarded directly
