Problems solved by technology

[0017] From the above description, it can be seen that if the method of message forwarding across data centers in the existing technology is adopted, multicast needs to be deployed, and the VTEPs of the two data centers are added to the same multicast group. When connecting, because there is no open multicast, it cannot run; at the same time, it is inefficient to

Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0035] The core idea of ​​the present invention is to run VXLAN and Locator / Identity Separation Protocol (LISP, Locator / Identity Separation Protocol) in the core network at the same time, LISP is used as the control plane protocol of VXLAN, but not as the packet encapsulation of the data plane, the data plane Still send and receive in VXLAN encapsulation. In this way, when interconnecting across data centers, VXLAN can also run without multicast. At the same time, the LISP protocol can be used to perceive the corresponding relationship between the host, MAC and VTEP, without the flooding learning mechanism of the data plane. Through the method of the present invention, ARP flooding in the core network is reduced, flooding and learning m...

Abstract

The invention discloses a method and device for forwarding messages. An ARP request message sent by a first VM is received by a first VTEP, a mapping request message is sent to a second VTEP through a mapping system, and a mapping relationship between an EID and an RLOC of a second VM under the second VTEP is requested; a mapping response message returned by the second VTEP is received by the first VTEP and the mapping relationship between the EID and the RLOC of the second VM is learned, wherein the EID is an MAC address, an IP address and a VNI of the second VM; the RLOC is an IP address of the second VTEP; the messages sent to the second VM by the first VM are received by the first VTEP, according to the stored mapping relationship between the EID and the RLOC of the second VM, VXLAN packaging is conducted on the messages, and the packaged messages are sent to the second VTEP and forwarded to the second VM through the second VTEP. The function that a VXLAN is operated efficiently under the condition that multicast is avoided is achieved.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message forwarding method and equipment. Background technique [0002] In a cloud computing multi-tenant environment, each tenant needs to be allocated a logical network that can be well isolated from other logical networks. Logical network isolation is generally solved by virtual local area network (VLAN, Virtual Local Area Network) technology. In the IEEE802.1Q standard, since the maximum number of VLAN identifiers is 12 bits, the maximum number of VLANs within a certain range is only 4K. With the increasing demand for multi-tenancy in the cloud environment, 4K VLANs can no longer meet the needs of large-scale network deployment in data centers. In addition, in a cloud computing environment, workloads often need to be migrated among multiple data centers and multiple cloud platforms, while the current IP subnet-based zoning limits the application of Layer 2 co...
