Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings and according to the embodiments.

[0022] This application provides a message processing method in SDN, which implements inter-VXLAN intercommunication requirements by controlling devices to answer Address Resolution Protocol (ARP) request messages and sending forwarding flow tables to data messages. In the SDN of this application, the intercommunication between different VXLANs can be realized without a VXLAN gateway device, thereby solving the problem that the VXLAN gateway becomes a forwarding bottleneck.

[0023] In the embodiment of the present application, the control device configures a global virtual media access control (MediaAccessControl, MAC) address, uses the global virtual MAC address as the MAC address of the gateway device, and execu...

Abstract

The invention provides a software definition network message processing method. The software definition network message processing method is characterized in that a forwarding flow graph request, which can be reported because of inability of matching a data message forwarded by a host device according to requirements with a forwarding flow graph, can be received; when the target MAC address of the data message is the global virtual MAC address, the forwarding flow graph can be generated according to the global port; the forwarding flow graph comprises the operation instruction of replacing the target MAC address of the data message by the MAC address of the global port graph matched with the target IP address of the data message; the forwarding flow graph can be transmitted to the host device, which can be used to forward the data message matched with the forwarding flow graph. Based on the same conception, the invention also provides a software definition network message processing device, and therefore the distributed routing can be realized, and the VXLAN gateway is not the bottleneck of the cross-network segment forwarding any more.

Description

technical field [0001] The invention relates to the field of communication technologies, in particular to a method and device for processing messages in a software-defined network. Background technique [0002] The general framework of the overlay (Overlay) network is to realize the bearer of the application on the network without large-scale modification of the basic network, and can be separated from other network services, and the basic network based on the Internet Protocol (Internet Protocol, IP) technology-based. The basic principle of Overlay is to enable virtual machines to communicate in the tunnel through a tunnel encapsulation technology. [0003] Software Defined Network (SDN) technology is a new type of network communication architecture, which realizes centralized control and distributed forwarding of network devices. In the concept of SDN technology, the network function is divided into two parts, the control device and the data channel, and the two parts in...
