Problems solved by technology

[0004] When the sender wants to send the same data packet to multiple VMs at the same time, the multicast agent needs to copy it into multiple data packets and send them separately, resulting in a large network resource overhead

Abstract

The embodiment of the present application discloses a data packet forwarding method for receiving and processing multicast packets. The method in the embodiment of the present application includes: the gateway receives the data message; the gateway obtains the virtual network identifier VNI corresponding to the data message and the source network protocol IP address, the destination IP address, the destination port and the transport layer protocol; the gateway according to The VNI determines the source port; the gateway performs hash balance calculation according to the source port, the IP address, the destination IP address, the destination port and the transport layer protocol to obtain a set of forwarding cores; Each forwarding core in the set of forwarding cores sends the data packet. The load balancing between the forwarding cores in a single POD is realized, so that when the data message sent by the sender is a multicast message, the VPC system can also receive and process it, and the sender does not need to send unicast messages to VMs one by one, saving Network resource overhead.

Description

technical field [0001] The present application relates to the field of communications, and in particular to a method and device for forwarding data packets. Background technique [0002] Public cloud refers to a free or low-cost cloud that a third-party provider provides to users through the Internet. In the process of providing services in the public cloud, the enterprise does not own cloud computing resources, but provides services to external users through the infrastructure of the public cloud, and external users access the public cloud through the Internet to receive the services of the enterprise. [0003] In some example applications of the public cloud, the sending end is deployed in the data center of the enterprise, and the receiving end is a virtual machine VM in multiple subnets under the virtual private cloud VPC system. At present, the data message sent from the sending end to the receiving end mainly adopts a multicast-to-unicast mode of multicast proxy. Spe...
