AI Technical Summary

Problems solved by technology

However, if some physical NICs on the same computing node do not support DPDK or require kernel-mode forwarding due to business reasons, and other physical NICs require high-performance forwarding in user mode, the native virtual switch cannot use a single type of bridge for unified management Virtual ports and data forwarding make it difficult to communicate between virtual machines of different business types
If the ports on the kernel-mode forwarding bridge need to communicate with the ports on the user-mode forwarding bridge, they can only rely on some external connections to communicate with each other, which affects performance and complicates configuration.

Embodiment Construction

[0038] Embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0039] see figure 1 with figure 2 As shown, the embodiment of the present invention provides a data forwarding method of a virtual switch based on a hybrid virtual network bridge, including the following steps:

[0040] The control plane creates a virtual network bridge in the data plane and sets the bridge type to hybrid; creates a user mode forwarding module in user space, and creates a kernel mode forwarding module in kernel space;

[0041] The user-mode forwarding module and the kernel-mode forwarding module apply for a piece of shared memory, and respectively open the shared memory polling thread to detect whether a message enters the shared memory;

[0042] According to the needs of business deployment, add the physical network card to the virtual network bridge in a specified type;

[0043] The virtual bridge receives the data messag...

Abstract

The invention discloses a data forwarding method and device of a virtual switch based on a hybrid virtual bridge, and relates to the technical field of cloud platform network virtualization. The invention creates a hybrid virtual bridge, which includes a user state forwarding module and a kernel state forwarding module , the user-mode forwarding module and the kernel-mode forwarding module apply for a piece of shared memory, and through the shared memory, the port of the kernel-mode forwarding module and the port of the user-mode forwarding module can forward data to each other, open up the data channel between kernel-mode forwarding and user-mode forwarding, and realize all High-performance communication between state-operating network cards.

Description

technical field [0001] The invention relates to the technical field of cloud platform network virtualization, in particular to a data forwarding method and device of a virtual switch based on a hybrid virtual network bridge. Background technique [0002] In cloud platform products, ovs (open vswitch) open source components are widely used as virtual switch applications. As a mature product-level virtual switch, ovs can provide stable and powerful virtual forwarding functions. [0003] With the rise of edge cloud computing, in order to make full use of server resources, the business scenarios undertaken are becoming more and more complex, and the infrastructure environment is also becoming more and more complex. Various types of network cards and communication methods need to be managed and realized. The native virtual switch (ovs) can no longer be satisfied. [0004] ovs is a virtual switch that forwards packets based on the openflow protocol through openflow flow table rul...
