Technical Field
The present invention relates to communications technologies, and in particular, to a method, a device, and a computer storage medium for service transmission.
Background
With the development of communication technology, the internet, the cable television network and the telecommunication network are integrated with each other, and a unified network system is gradually formed. Among the three networks, the transmission technology of the telecommunication network needs to be changed from Synchronous Digital Hierarchy (SDH) technology to ethernet technology mainly based on packet transmission technology.
As for the SDH technology, it is a circuit transmission technology, and specifically, a dedicated and exclusive circuit channel is established between two clients to transmit information, and its advantages are short transmission delay time, small delay jitter, high reliability, and is very suitable for transmission of voice services; but when no information is transmitted between the two clients, as long as the dedicated channel is not revoked, the dedicated circuit channel is still in a state of being shared by the two clients, so that other clients cannot use the dedicated circuit channel, and the transmission efficiency is low. For the packet transmission technology, a message format is adopted between two clients to transmit information, and the specific scheme is that a virtual transmission channel is established between the two clients, the two clients transmit messages through the virtual channel, the virtual channel can be established on a physical entity channel, and all the clients share the bandwidth resources of the physical entity channel. When no information is transmitted between the two clients, the bandwidth resources of the virtual transmission channel are shared to other clients for use, so that the virtual transmission channel has a good multiplexing characteristic, and the bandwidth is guaranteed not to be wasted, so that the transmission efficiency is high, and the transmission cost is low.
However, in terms of the packet transmission technology, when a certain client a starts to have service packet transmission, if other clients are sending packets, the client a needs to wait for the other clients to finish sending the current packet before retrieving the bandwidth of the virtual channel, which results in that the packet of the client a cannot be sent in time, and therefore, there are uncertain time delay during sending the packet and jitter caused by fluctuation of the time delay. In addition, when a packet transmitted between a pair of clients needs to pass through many intermediate node devices on the network, the packet will cause delay and jitter of different degrees each time it passes through one intermediate node device of the network, and the delay and jitter will be accumulated after passing through multiple intermediate node devices, resulting in serious reduction of service transmission quality. Therefore, in the process of three networks integration, when the voice service is transmitted by using the packet transmission technology, the transmission quality of the voice service is reduced due to the above-mentioned problems, and the high-quality transmission of the voice service cannot be realized.

Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Referring to fig. 1, it shows an architectural schematic of a communication network 100 capable of applying a packet transmission technology, where the communication network 100 includes a plurality of client devices and a plurality of network node devices. The client devices are respectively a client 1, a client 2, a client 3 and a
It should be noted that the communication Network 100 may be applicable not only to Ethernet, but also to communication networks based on packet transmission, such as an Optical Transport Network (OTN) and a Flexible Ethernet (FlexE), which are not described in detail in this embodiment of the present application.
Taking fig. 1 as an example, in the process of information transmission, information is generally transmitted in a message manner, and the length of each message is variable, and is generally 64 bytes to 1518 bytes. When the client 1 has no message to transmit to the client 2, the bandwidth of the transmission channel 1 may be shared to other clients for use, for example, may be shared to the transmission channel 2 for use. When the client 1 needs to transmit the message to the client 2, if the transmission channel 2 is being used by the client 3 and the
For the communication device, fig. 2 shows a specific flow in the process of transmitting a message, and it can be seen that, after the message received by the physical inlet is analyzed and classified, a sending port of the message may be determined according to feature information of the message, such as the content of the MAC address, the IP address, the priority, and the like of the message, and a queue, such as queue 1, queue 2, queue n in the figure, is queued, and then is waited to be scheduled and output to the physical outlet. It can be seen that the scheduler can call out messages from different queues according to a predetermined scheduling algorithm, and send the messages to the physical outlet for sending. Because the lengths of each message are different, even though the scheduling algorithm can ensure that the message has a certain output bandwidth, when one message needs to be sent and output, the next message can be sent only after the last message is sent, the waiting time is uncertain, and delay jitter is also brought by the uncertainty of the delay time. Each time a message passes through one network node device, delay and jitter of different degrees exist, delay time and delay jitter accumulated after the message passes through a plurality of devices are very large, so that transmission quality in a packet transmission process is unstable, and when high-quality voice services need to be transmitted, for example, large customer private line services such as a power network, a military network and a railway network, the quality of the voice services is greatly reduced, and the quality requirements of the private line services cannot be met.
In view of the above hidden troubles in the related art, the embodiment of the present invention provides the following technical solutions based on the network architecture shown in fig. 1.
