Embodiment Construction

[0083] The application will be described in further detail below in conjunction with the accompanying drawings.

[0084] According to one aspect of the present application, a method for sending packets at the source switch is provided, the method is implemented at the source virtual switch, and specifically includes step S201 and step S202, wherein the step S201 is received from the source virtual machine An Internet Protocol message to be sent, the Internet Protocol message includes the Internet Protocol address of the target virtual machine and actual content, wherein the actual content is the data information actually to be transmitted in the message; the step S202, based on the Described Internet protocol message, generates virtual extensible local area network (Virtual Extensible LAN, VxLAN) message, and here, described VxLAN message is the VxLAN message that goes to purpose Media Access Control (Media Access Control, MAC) address; Then, Send the VxLAN message to the swit...

Abstract

The invention aims at providing a method and device for sending and receiving a message. The method for sending and receiving the message comprises firstly, receiving an internet protocol message to be sent from a source virtual machine, then removing a target media access control address in the internet protocol message in order to generate a virtual extensible LAN message, and finally sending the virtual extensible LAN message to a switch corresponding to a target virtual machine according to a preset address list recorded with the mapping relation between the internet protocol address of the target virtual machine and the internet protocol address of a host machine. The media access control address learning problem is solved, at the same time, the virtual extensible LAN message gettingrid of the redundant media access control address is employed, the message is forwarded completely based on the internet protocol address of the target virtual machine, the bandwidth utilization rateis effectively increased, and good scalability is achieved at the same time.

Description

technical field [0001] This application relates to the field of computers, and in particular to a technique for sending messages. Background technique [0002] With the continuous development of cloud computing, in a multi-tenant cloud computing environment, users need an isolated network environment, which includes independent address space, complete isolation of network traffic between virtual networks, and independent Quality of Service (QoS) Assure. In the cloud computing environment, the existing technology adopts virtual extensible local area network (Virtual Extensible LAN, VxLAN) and other tunnel encapsulation protocols to realize the isolation of virtual networks between tenants, but due to the tunnel encapsulation protocol, for example, the VxLAN protocol introduces an additional 50 Byte to help realize the forwarding of the message, which reduces the actual utilization of the bandwidth; on the other hand, the VxLAN protocol relies on the multicast / broadcast of th...
