Example (b):
in the existing internet communication application, in order to enable data to be transmitted efficiently, various data transmission adjustment strategies are often applied, in a conventional transmission strategy, a requirement of a client on data is obtained firstly, then corresponding data is transmitted through an operation server, when the data is transmitted, the data is not received by the client, so that the corresponding data is often sent continuously after the feedback of the client is waited, in such a handling way, when the operation server operates at a high load, if the client requests are urgent, the timeliness requirement of the data requests is difficult to meet, in order to solve the technical problem, the existing method is to directly allocate system resources to preferentially transmit data with higher priority, but the system resources are easily wasted due to the fact that the allocation of the system resources is quantitative allocation, and further the transmission of other data is influenced.
The invention aims to provide a data transmission management method which can meet the timeliness of data transmission with higher data priority and avoid the waste of system resources.
Therefore, the present invention discloses a data transmission management method, which is applied to a data transmission process between a service end and a client end, and referring to fig. 1, the data transmission management method includes:
step S100, obtaining client data request information, and determining a data priority, a data type, and a corresponding data amount of data to be prepared for transmission according to the client request information.
The data types comprise network protocol and management protocol data, real-time service data, large data volume service data, streaming media data and common service data.
The network protocol and management protocol data require low time delay and low packet loss rate, but the requirement on bandwidth is not high, the real-time service data protocol requires high bandwidth, low time delay and low jitter, the large data volume service data refers to a network service with a long-time large data transmission behavior, and the service requires the network packet loss rate as low as possible, so that a flow shaping function can be configured for the message, the message sent from an interface is cached through a data buffer area, the packet loss phenomenon caused by congestion due to burst flow is reduced, the requirements of the stream media data on network time delay, packet loss and jitter are low, and the common service data has no special requirements on the network and is not high in importance.
Factors that affect the quality of data transmission include bandwidth, transmission delay and jitter, and packet loss rate.
Here, bandwidth, also referred to as throughput, refers to the maximum number of data bits transmitted from one end of the network to the other end in a fixed time (1 second), and may also be understood as the average rate of a particular data flow between two nodes of the network. The unit of bandwidth is bits per second (bit/s). In a network, there are two common bandwidth-related concepts: an uplink rate and a downlink rate. The uplink rate refers to the data transmission rate when the user sends information to the network, and the downlink rate refers to the transmission rate when the network sends information to the user. For example, a user uploads a file to a network through an FTP, and what influences the speed of uploading the file is an uplink rate; and downloading files from the network, what influences the speed of downloading files is the downlink rate.
The delay refers to a delay time required for a packet or packet to pass from a transmitting end to a receiving end of a network, and generally includes a transmission delay and a processing delay. In the case of speech transmission, the delay refers to the time from when the speaker starts speaking to when the other party hears the spoken content.
Jitter is used to describe the degree of delay variation, i.e., the time difference between the maximum delay and the minimum delay. Jitter is an important parameter for real-time transmission, and particularly real-time services such as voice and video are very intolerant to jitter, which can cause interruption of voice or video.
The packet loss rate is the percentage of the number of lost messages in the network transmission process to the total number of transmitted messages. A small amount of packet loss has little influence on the service, for example, in voice transmission, information of one bit or one packet is lost, and both parties of a call often cannot notice the loss.
Step S200, determining a data transmission policy according to the data type and the corresponding data amount of the data to be transmitted.
It should be understood that the data transmission strategy includes a plurality of kinds, and the differentiated services data transmission strategy is explained herein by way of example, and the basic principle thereof is to divide data into a plurality of classes, each class enjoys different processing, and especially different classes enjoy different levels of processing when the network is congested, so as to obtain different packet loss rates, delays and delay jitters. The services of the same type can be aggregated and uniformly transmitted in the network, so that the same time delay, jitter and packet loss rate are ensured.
Referring to fig. 3, the data transmission policy sequentially handles data by performing label classification, rate limiting of a traffic monitoring interface, and other processing according to data types, then performing congestion management, generating a plurality of data transmission queues, scheduling the data transmission queues, and finally transmitting the data out of the interface.
Step S300, acquiring the real-time system resource consumption condition of the operation server, assigning the real-time system resource consumption condition, if the assignment of the real-time system resource consumption condition of the operation server is larger than a preset value, allocating the system resource according to the data priority, and when allocating the system resource, performing equal-proportion allocation according to the data receiving capacity of the client to preferentially send data to the corresponding client.
The system resources include a data transmission allocation thread, an interface network bandwidth, a memory occupation ratio and a processor occupation ratio.
