Problems solved by technology

[0004] However, in the above method, since the starting point switching device needs to determine the VXLAN tunnel header in the process of forwarding the data message, the above starting point switching device needs to configure hardware resources such as a VXLAN tunnel table, a VXLAN interface table, a routing table, and a MAC table, and It is also necessary to configure the VXLAN protocol and routing protocol. The configuration and management of the network are more complicated, which also makes the forwarding process of data packets more complicated.

Embodiment Construction

[0040] The forwarding method and apparatus of the data packets provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0041] The terms "first" and "second" of the embodiments of the present invention and the "first" and "second" or the like are used to distinguish different objects rather than to describe the specific order of the object. For example, the first flow table and the second flow table or the like are used to distinguish different flow tables rather than to describe a particular order of the flow tables.

[0042] In the embodiments of the invention, "exemplary" or ",,,,,,,,,,,,,,,,,, Any embodiment or design of "exemplary" or "," or ",", in the embodiment of the present invention should not be construed as being more preferred or more advantageous than other embodiments or design. Specifically, the use of "exemplary" or ", for example," is intended to present the relevant concept in a specif...

Abstract

An embodiment of the present invention provides a method for forwarding data packets, which relates to the technical field of computer networks, can simplify network configuration and management, reduce the complexity of forwarding data packets by switching equipment, and reduce the cost of switching equipment. The method includes: the SDN controller determines the first flow table and the second flow table; and the SDN controller sends the first flow table to the first switching device, and sends the second flow table to the second switching device, the first flow table is used to indicate the first flow table A switching device encapsulates the first data packet after receiving the first data packet, and the second flow table is used to instruct the second switching device to decapsulate the encapsulated first data packet after receiving the encapsulated first data packet For the first data message, the first switching device is the starting switching device in the VXLAN tunnel, and the second switching device is the ending switching device in the VXLAN tunnel.

Description

Technical field [0001] Embodiments of the present invention relate to the field of computer network technologies, and more particularly to a forwarding method and apparatus for data packets. Background technique [0002] With the development of the virtual local area network, the method of forwarding data packets through the VXLAN tunnel is increasingly concerned by the Virtual Extensible LocalaRea Network (VXLAN) technology. [0003] Such as figure 1 As shown, the current point switching device in the network is currently in the forwarding process of data packets (ie figure 1 Switching Apparatus 1) After receiving the data packets transmitted by the traffic server 1 by the input port of the switching device 1, the switching device 1 is connected to the VxLAN tunnel table, the VXLAN interface table, the routing table, and media. MEDIAACCESS CONTROL, MAC table, determine the VXLAN tunnel header, including the VxLAN head, User Data Protocol, Abbreviation UDP) Head, Internet Protoco...
