Embodiment Construction

[0029] In the following description, specific details such as specific system structures and technologies are presented for the purpose of illustration rather than limitation, so as to thoroughly understand the embodiments of the present invention. It will be apparent, however, to one skilled in the art that the invention may be practiced in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, devices, circuits, and methods are omitted so as not to obscure the description of the present invention with unnecessary detail.

[0030] In order to illustrate the technical solutions of the present invention, specific examples are used below to illustrate.

[0031] Such as figure 1 As shown, the application discloses a multicast method, including:

[0032] Step S101, sending target data to the receiver;

[0033] Step S102, receiving the first instruction sent by the receiver, updating the number of target data that can b...

Abstract

The invention provides a multicast method and terminal equipment suitable for the field of communication technology. A sender sends target data to a receiver; after that a first instruction is received from the receiver, the amount of target data that can be sent is updated, control instructions received from the receiver are counted, when the number of the control instructions received from the receiver exceeds a second preset number, the target data is not sent any more, and a second instruction is generated and sent to the receiver; and a third instruction is received from the receiver, thenumber of the control instructions that can be received is reset as the second preset number according to the third instruction, and sending of the target data is recovered. Thus, both the data sender and receiver can count the amount of data in real time, data loss can be discovered timely, and the problem of transmission instability caused by data loss is solved.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a multicast method and terminal equipment. Background technique [0002] Multicast transmission: A point-to-multipoint network connection between the sender and each receiver. If a sender transmits the same data to multiple receivers at the same time, only one copy of the same data packet is required. It improves data transfer efficiency. Reduces the possibility of backbone network congestion. [0003] RDMA (Remote Direct Memory Access) was created to solve the delay of server-side data processing in network transmission. RDMA transfers data directly to the storage area of ​​the computer through the network, and quickly moves data from one system to the remote system memory without any impact on the operating system, so that it does not need to use much computer processing power. It eliminates the overhead of external memory copying and context switching, th...
