Embodiment Construction

[0051] Such as figure 1 As shown, multiple servers can be deployed in the VXLAN network, such as sever1-serverN, and one server can be virtualized into multiple virtual machines, such as vm1-vmN, or even more, and a virtual machine is equivalent to a host, Based on this, the number of hosts in a VXLAN network can vary by orders of magnitude. At the same time, the VXLAN network introduces a user identifier similar to VLANID, called the VXLAN network identifier VNI (VXLAN Network Identifier), which consists of 24 bits and supports up to 16M VXLAN segments, thus satisfying a large number of user identifiers. Through VXLAN, a large number of tenants can be connected to the virtual network, and tenants can plan their own virtual network without considering the restrictions of physical network IP addresses and broadcast domains, which reduces the difficulty of network management. However, VXLAN does not solve the problem of Layer 2 network traffic flooding, and because VXLAN techn...

Abstract

The invention discloses a communication processing method and device, the method is applied to a first communication site in a VXLAN network, and the method comprises the steps: receiving a request message broadcasted by a first host; analyzing a header of the request message to obtain an IP address of a second host in the request message; if the IP address of the second host represents that a second communication site to which the second host belongs is different from the first communication site or the second host and the first host respectively correspond to different VNIs, transmitting a first reply message to the first host, wherein the first reply message comprises an MAC address of the first communication site, so that when the first host communicates with the second host, a communication message can be generated by taking the MAC address of the first communication site as a destination MAC address; after receiving the communication message sent by the first host, the first communication station can package the communication message into a communication message supporting a preset type of IP protocol, and transmits the communication message through the communication gateway based on the IP protocol.

Description

technical field [0001] The present application relates to the technical field of network transmission, and in particular to a communication processing method and device. Background technique [0002] The extended virtual local area network VXLAN (Virtual eXtensible Local Area Network) is a network virtualization technology in NVO3 (Network Virtualizaiton over Layer 3), which can establish a layer-2 Ethernet network tunnel on the basis of a layer-3 network to achieve cross-region Layer 2 interconnection. As one of the core technologies of cloud computing, server virtualization has been more and more recognized and deployed due to its advantages of greatly reducing network costs, improving business deployment flexibility, and reducing operation and maintenance costs. In addition, VXLAN introduces a user identifier similar to the virtual local area network identifier VLAN ID (VirtualLocal Area Network Identification), called the VXLAN network identifier VNI (VXLANNetwork Ident...
