Abstract

The embodiment of the invention discloses a congestion method and congestion control equipment of a user datagram protocol (UDP) service, and relates to the technical field of communication, capable of controlling congestion of the UDP service, reducing a packet loss probability of a UDP service data packet caused by relatively poor downlink network quality, and thus improving data transmission reliability. The specific scheme of the method comprises the steps as follows: a base station receives a first UDP service data packet sent by a server, wherein the first UDP service data packet is thedata packet corresponding to a UDP service initiated by a client, the second UDP service data packet is the data packet corresponding to the UDP service initiated by the client, the second UDP servicedata packet is cached in a cache space which is pre-configured by the base station aiming at the UDP service, and the size of the cache space is determined according to the quality of a downlink network between the base station and the client; and if the cache space is full, the base station discards the first UDP service data packet, and sends a congestion message to the server.

Description

Technical field

[0001] The embodiments of the present invention relate to the field of communication technology, and in particular to a method and equipment for congestion control of UDP services. Background technique

[0002] In network communication, the User Datagram Protocol (UDP) can compress network data traffic into the form of data packets. UDP has the characteristics of low resource consumption and fast processing speed when processing data packets. It is used in audio, video and It is widely used in data transmission.

[0003] For UDP services, when the server transmits UDP service data packets to the client, the client does not send an acknowledgement to the received data packet, and the server cannot confirm how many data packets are completely received by the client in how long. Due to the uncertainty of the network quality between the base station and the client, the UDP service data packet is easily discarded on the base station side, resulting in unreliable data tr...

Embodiment Construction

[0021] The terms "first" and "second" in the description and claims of the embodiments of the present invention are used to distinguish different objects, rather than to describe a specific order of objects. For example, the first UDP service data packet and the second UDP service data packet are used to distinguish different UDP service data packets, rather than describing a specific sequence of records.

[0022] In the description of the embodiments of the present invention, unless otherwise specified, the meaning of "plurality" means two or more. For example, multiple processors refer to processors that include two or more physical cores.

[0023] In addition, the terms "including" and "having" and any variations thereof mentioned in the description of the embodiments of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or device that includes a series of steps or modules is not limited to the listed steps or ...
