Problems solved by technology

[0005] However, the solutions in the prior art also expose the following problems: 1) Since the information stored by each SDN controller needs to be shared and synchronized, the sharing and synchronization of a large amount of information across the WAN will lead to increased network overhead and increase the number of SDN controllers. 2) Since the virtual machines communicate with each other, there is a transmission path between the communicating virtual machines, such as Figure 1-B As shown, the full mesh network between virtual machines increases the complexity of the network system. At the same time, the SDN controller needs to manage the transmission path between every two communication virtual machines in real time, which wastes the processing resources of the SDN controller and reduces Improves the processing efficiency of the SDN controller for data packets

Abstract

An embodiment of the invention relates to a data packet processing method and device. The method includes the steps: receiving a data packet forwarded by a source virtual switch and transmitted by a source virtual machine by a source controller; recognizing whether a TP (teleprocessing) address is stored in an address list or not by the source controller; determining that an objective virtual machine is not positioned in a source data center by the source controller if the TP address is not stored in the address list; determining first forwarding rules for forwarding the data packet to the objective virtual machine by the source controller; respectively transmitting the first forwarding rules to the source virtual switch and a source virtual proxy by the source controller, accordingly, forwarding the data packet to the source virtual proxy according to the first forwarding rules by the source virtual switch, and forwarding the data packet to an objective data center of the objective virtual machine according to the e first forwarding rules and a stored route forwarding table by the source virtual proxy. The source controller, the source virtual switch, the source virtual machine and the source virtual proxy are positioned at the source data center.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a data packet processing method and device. Background technique [0002] In order to realize services such as disaster backup and dynamic migration of virtual machines across data centers, at present, by combining the SDN cluster control technology of the Wide Area Network (Wide Area Network, WAN for short) (Software Defined Network, SDN for short) with the Virtual Extended LAN ( Virtua l Extensible LAN, referred to as: VXLAN) technology is combined to realize the overlay (over lay) layer 2 network between multiple data centers, providing customers with flexible expansion capabilities. [0003] Such as Figure 1-A As shown, the combination of SDN cluster control technology and VXLAN technology realizes the two-layer network interconnection between multiple data centers. Each data center has SDN controllers, aggregation switches, access switches, and multiple physical serv...
