Problems solved by technology

[0004] Generally, there are many terminals. If the terminal sends a large number of uplink data packets, there will be too many uplink data packets stored in the cache processor, resulting in congestion. At the same time, the cache processor may overflow some uplink data packets. Speech distortion occurs

Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] The asynchronous time-delay network communication method usually performs data communication with a time frame as a cycle, and the asynchronous time-delay network may be a network communicating in a polling manner, and the network may be a full-duplex network, and the downlink and uplink occupy different Channel.

[0025] Such as figure 1 As shown, the asynchronous delay network communication method of the present invention includes the following steps, S101, within the first time frame period, the server sends downlink data information to the first cache processor, and simultaneously receives uplink data sent by the first cache processor information; S102, the second cache processor sends downlink data information to the terminal, and the terminal sends uplink data information to the second cache processor; S103, within the second ti...

Abstract

The invention discloses an asynchronous time delay network communication method, system and cache processing device, the communication method specifically comprises: during the first time frame period, a server sends downlink data information to a first cache processor, and receives uplink data information sent by the first cache processor; a second cache processor sends downlink data information to a terminal, the terminal sends uplink data information to the second cache processor; during the second time frame period, the server receives the uplink data information sent by the second cache processor, and sends downlink data information to the second cache processor; the first cache processor sends downlink data information to the terminal; the terminal sends uplink data information to the first cache processor. The asynchronous time delay network communication method according to the invention can relief the condition of data information congestion or data information loss occurred in the cache processor.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to an asynchronous delay network communication method, a system thereof, and a cache processing device. Background technique [0002] The wide application of IP (Internet Protocol, Internet Communication Protocol) network and the rapid development of multimedia technology make it very important to carry out multimedia communication on IP network. IP VoIP generally refers to a system for voice communication in a computer network that uses IP as the network layer protocol. The technology it uses is collectively called VoIP (Voice over IP, IP VoIP), that is, voice is transmitted over IP. [0003] The transmission principle of the IP network phone in the prior art is: a cache processor is connected between the server (such as a switch) and the terminal (such as a mobile phone, a telephone), and the uplink data packet sent by the terminal is stored and forwarded to the serv...
