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 (Media Access Control, MAC) address, and uses the global virtual MAC address as the MAC address of the gateway device, and...

Abstract

The present invention provides a message processing method in a software-defined network. The method includes: receiving a forwarding flow table request sent by a host device because the data message to be forwarded does not match the forwarding flow table, and the data message When the destination MAC address of the data packet is the global virtual MAC address, a forwarding flow table is generated according to the global port table. The forwarding flow table includes: replace the An operation instruction of the destination MAC address of the data message; and sending the forwarding flow table to the host device, so that the host device forwards the data message matching the forwarding flow table. Based on the same inventive idea, this application also proposes a packet processing device in a software-defined network, thereby realizing distributed routing, so that the VXLAN gateway no longer becomes a bottleneck for cross-network segment forwarding.

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...
