Problems solved by technology

[0004] However, when the cloud resource server establishes a connection for the first time, it needs to establish a tunnel first, which will cause the client's multicast data packets to stay locally
When the number of cloud resource servers is greater than 650, due to the limitation on the number of OVS output ports, it will cause the failure of sending multicast packets

Embodiment Construction

[0024] A detailed description will be given below of embodiments of the present invention. Although the present invention will be described and illustrated in conjunction with some specific embodiments, it should be noted that the present invention is not limited to these embodiments. On the contrary, any modification or equivalent replacement made to the present invention shall be included in the scope of the claims of the present invention.

[0025] Some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

Abstract

The invention provides a multicast data packet communication method, an apparatus and a system. A first multicast data packet sent by a client is received by an OVS and is converted into a unicast data packet. The OVS sends the unicast data packet to a multicast data packet communication apparatus. The multicast data packet communication apparatus forwards a second multicast data packets to multiple related cloud resource servers based on the unicast data packet. Through the multicast data packet communication apparatus, the processing speed of the multicast data packet is accelerated, especially for a large number of cloud resource servers, and the forwarding of a lot of multicast data packets can be realized.

Description

technical field [0001] The invention relates to the field of computer communication, in particular to broadcast data packet communication in a virtual network. Background technique [0002] A virtual switch (Open VSwitch, OVS) is a virtual switch software, which is mainly used as a virtual switch in a virtual machine environment. OVS supports a distributed environment of multiple hosts. OVS can be used to transfer traffic between virtual machines, or to communicate between virtual machines and external networks. [0003] In an OVS-based virtual network, when a client sends multicast data packets (ie, broadcast streams) such as broadcast and multicast, OVS receives multicast data packets. Since there are usually multiple clients in a large virtual network at the same time, in order to achieve isolation between multiple clients, OVS needs to forward the multicast data packets to the tunnel port of the corresponding cloud resource server in the form of a tunnel. . [0004] H...
