Embodiment Construction

[0049] In order to solve the problems existing in the prior art that special hardware network cards need to be used as PEs, resulting in high cost, poor interoperability, and inability to be widely used, an embodiment of the present application provides a message processing method and device in a virtualization system .

[0050] The embodiment of this application is applied to such as figure 1 In the shown virtualization system, the virtualization system forms a CB-PE architecture. The system mainly includes: a physical server and its directly connected physical access switch. The structures of the physical server and the access switch are introduced below.

[0051] 1. Physical server

[0052] A common SR-IOV (Single Root IO Virtualization, single root IO virtualization) network interface card (Network Interface Card, NIC) is installed on the physical server, and the virtualization software layer Hypervisor runs on the physical server. The Hypervisor can also be called Vir...

Abstract

The invention discloses a message processing method and device in a virtualized system. the method includes the steps that a vSwitch receives a UNTAG data message sent by a VM through a VF corresponding to the VM, wherein the UNTAG data message carries no VLAN ID of the VM; the vSwitch finds a corresponding mark VLAN according to the VF and adds the VLAN ID of the found mark VLAN to the UNTAG data message so that a 802.1Q message can be obtained, wherein the VF corresponds to the mark VLAN one to one; the vSwitch sends the 802.1Q message carrying the VLAN ID of the mark VLAN to an access switch which has direct access to a physical server. In the message processing method and device, an ordinary network card can be used, in other words, a universal SR-IOV NIC serves as PE, cost is saved, the intercommunity is good, and the message processing method and device can be widely applied.

Description

technical field [0001] The present application relates to the technical field of virtualization, and in particular to a message processing method and device in a virtualization system. Background technique [0002] PE (Port Extender, port extender) technology is to provide port expansion for CB (Control Bridge, control bridge) through PE, so that the network can achieve multi-level expansion. [0003] Among the existing PE technologies, there are mainly Multichannel (multi-channel) / S-Channel (service provider channel) PE defined by 802.1Qbg, PE defined by 802.1BR, and Cisco (Cisco) VN-TAG (Virtual Network-TAG , virtual network label) PE defined by proprietary technology. These three schemes are introduced respectively below. [0004] 1. PE in Multichannel / S-Channel mode defined by 802.1Qbg [0005] In this solution, the CB-PE architecture mainly includes: a physical server and its directly connected physical switch, the physical server includes: a virtual machine (Virtual...
