Problems solved by technology

[0003] The business data generated by important users or information cannot be transmitted in a timely manner. The reason is that the data identification of the current network mainly relies on two aspects of delay and reliability, and does not consider the requirements of other levels.
Regardless of whether the user who generates this type of service data is an important user, or whether a data packet of a certain type of service data needs to be processed urgently and preferentially, the network will adopt the same forwarding strategy due to the same data identifier based on the service type, resulting in Such users or data cannot be prioritized and guaranteed, and cannot provide differentiated transmission service guarantees

Embodiment 1

[0030] Embodiment one: a kind of IP data priority setting method specific steps:

[0031] Step S101, receiving data;

[0032] Step S102, extracting the DSCP encoding value in the IP data packet;

[0033] Step S103, according to the data type field in the DSCP code value, perform the first-level priority classification of the data;

[0034] Step S104, performing importance classification according to the importance field in the format corresponding to the DSCP coded value;

[0035] Step S105, according to the first-level priority classification of the data type field and the second-level priority classification required by the important field, sort the data priority;

[0036] Step S106, sorting the data according to the priority of the data, and performing data exchange processing.

[0037] The specific steps of step 105 are: first process the data with the first level priority from high to low, and at the same time process the data with the second level priority from high t...

Abstract

The invention relates to the field of IP data transmission, in particular to an IP data priority setting method. The IP data priority setting method aims to solve problems in the prior art. Under an existing distinguishing service system, importance priority identifications are added on the basis of data service types, service data of the same type can be further distinguished, the service data of the same type have identifications with priority differences when generated by different users or on different situations, and accordingly more elaborated data transmission service can be provided. Importance fields of data with the same priority level are analyzed, then the data are classified according to the second priority level, and data exchange processing is carried out according to DSCP coded values composed of the first priority level classification of data classification fields and the second priority level classification required by the important fields and according to the priority level of the data.

Description

technical field [0001] The invention relates to the field of IP data transmission, in particular to an IP data priority setting method. Background technique [0002] In the process of network communication, different services have different requirements on network transmission delay, reliability guarantee, and security. Network exchange should provide different exchange controls for different service data. At present, the differentiated service guarantee technology of the communication network identifies the data based on the data service type. The division of the service type is based on the transmission delay and reliability guarantee required when the service data is transmitted through the network. When the data is exchanged in the network, it is mainly based on these two The indicator request is processed. For data services with the same transmission delay and reliability requirements in practical applications, more requirements are imposed on the data services due to ...
