本发明涉及计算机网络通信领域，尤其涉及一种在VxLAN中发送ARP报文发送方法、VTEP及VxLAN控制器。The invention relates to the field of computer network communication, in particular to a method for sending ARP messages in VxLAN, a VTEP and a VxLAN controller.
背景技术Background technique
现有技术应用虚拟可扩展局域网（Virtual extensible LAN，VxLAN）技术扩展网络虚拟化，用以得到足够数量的虚拟网络，来满足用户使用。In the prior art, a virtual extensible local area network (Virtual extensible LAN, VxLAN) technology is applied to extend network virtualization, so as to obtain a sufficient number of virtual networks to satisfy users.
基于VxLAN虚拟化网络的虚拟机之间建立通信过程具体如下：The process of establishing communication between virtual machines based on the VxLAN virtualization network is as follows:
源虚拟机（Virtual Machine,VM））发送地址解析协议(Address ResolutionProtocol，ARP)报文，用以请求目的VM的媒体访问控制（Media Access Control，MAC）地址；与源VM对应的源VxLAN隧道终端（VxLAN Tunnel Endpoint，VTEP）基于该ARP报文，构造因特网组管理协议（Internet Group Management Protocol，IGMP）报文，然后将该IGMP报文发送至与目的VM对应的目的VTEP，若该目的VTEP接收到该IGMP报文，则该目的VTE2会对该IGMP报文进行解析，并将解析结果广播至与目的VTEP对应的目的VM中，以便目的VM接收到该解析结果后，将自身的MAC地址通过目的VTEP2进行封装，然后反馈给源VM。源VTEP用于将源VM发送的报文封装成VxLAN报文，或者将VxLAN报文解封装发送给源VM；目的VTEP用于将目的VM发送的报文封装成VxLAN报文，或者将VxLAN报文解封装发送给目的VM。The source virtual machine (Virtual Machine, VM) sends an address resolution protocol (Address Resolution Protocol, ARP) message to request the media access control (Media Access Control, MAC) address of the destination VM; the source VxLAN tunnel terminal corresponding to the source VM (VxLAN Tunnel Endpoint, VTEP) constructs an Internet Group Management Protocol (Internet Group Management Protocol, IGMP) message based on the ARP message, and then sends the IGMP message to the destination VTEP corresponding to the destination VM. If the destination VTEP receives If the IGMP message is received, the destination VTE2 will analyze the IGMP message, and broadcast the analysis result to the destination VM corresponding to the destination VTEP, so that after receiving the resolution result, the destination VM will send its own MAC address through The destination VTEP2 performs encapsulation, and then feeds back to the source VM. The source VTEP is used to encapsulate the packet sent by the source VM into a VxLAN packet, or to decapsulate the VxLAN packet and send it to the source VM; the destination VTEP is used to encapsulate the packet sent by the destination VM into a VxLAN packet, or to The document is decapsulated and sent to the destination VM.
在实现上述对信息传输的过程中，现有技术中至少存在如下问题：源VTEP要想得到目的VM的MAC地址，源VTEP1就必须要在多个组播组中发送IGMP报文，以获得与目的VTEP对应的目的VM2的MAC地址，这样就导致源VTEP发送报文会占用大量信息传输带宽，使用了大量的数据流量，从而造成了资源的浪费。In the process of realizing the above information transmission, there are at least the following problems in the prior art: if the source VTEP wants to obtain the MAC address of the destination VM, the source VTEP1 must send IGMP messages in multiple multicast groups to obtain the MAC address of the destination VM. The MAC address of the destination VM2 corresponding to the VTEP causes the source VTEP to send packets that occupy a large amount of information transmission bandwidth and use a large amount of data traffic, resulting in a waste of resources.
