Embodiment Construction

[0086] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings.

[0087] Throughout this specification, a data stream consists of a series of data packets with the same header.

[0088] Throughout this specification, switches (including leaf switches and spine switches) may be physical switches or virtual switches. When the switch is a physical switch, the switch port is a physical port, and when the switch is a virtual switch, the switch port is a virtual port.

[0089] The present invention proposes a method for realizing LAG and MC-LAG in a software-defined data center network (English full name: Software Defined Data Center Network, abbreviation: SDDCN). The SDN controller monitors the status of each SDN switch to replace the function of MC-LAG PEERS in the traditional MC-LAG solution. Through the traffic behavior monitoring function of the controller, the ports of the same switch are automatically configur...

Abstract

The invention relates to a link aggregation system of a switch. The system comprises a switch, a controller and a server for establishing a communication connection with each other, wherein the switchis configured to receive a data packet from the server, generate data forwarding information corresponding to the data packet, and transmit the data forwarding information corresponding to the data packet to the controller; the controller is configured to store the data forwarding information corresponding to a plurality of data packets sent by the switch, confirm that at least two switch ports of the switch conform to a link aggregation condition according to the data forwarding information corresponding to the plurality of data packets, and transmit the first indication information to the switch; and the switch is configured to configure a logical port according to the first indication information, receive a first subsequent data packet, and transmit the first subsequent data packet through the logical port. The system simplifies the configuration process of link aggregation.

Description

technical field [0001] The present invention relates to a link aggregation system, method, device, equipment and medium. Background technique [0002] Software Defined Networking (full English name: Software Defined Networking, abbreviation: SDN) is a relatively new network design concept. Its core idea is to separate network device control from the data plane, centralize network control rights, and open programmable interfaces. Through the standard southbound interface, such as the well-known OpenFlow protocol, the SDN controller shields the differences of the underlying physical forwarding devices and realizes the virtualization of resources. At the same time, it opens up a flexible northbound interface for upper-layer services to configure and call the network as needed. Internet resources. [0003] The link aggregation group of the switch (English full name: Link Aggregation Group, abbreviation: LAG) and the multi-switch link aggregation group (English full name: Multi-...
