FIG. 1 is a flowchart of an embodiment of a service quality control method according to an embodiment of the present application, where the method may include the following steps:

101: The controller acquires a service identifier and a service quality requirement of the service transmitted in the wireless network.

When each wireless network device in the wireless network performs service transmission, it needs to perform service scheduling and the like through the bearer network of the wireless network, and the bearer network may refer to a network composed of devices connected to each wireless network device in the wireless network, such as a router and a switch. And other equipment.

Due to different types of services, such as session-based services and background-based services, the requirements for Quality of Service (QOS) may vary.

In the prior art, when the service is transmitted from the wireless network to the bearer network, the service model provided is usually a DiffServ (Differentiated Service) model, and the wireless network device is based on the DiffServ network technology, and only the service priority is scheduled. A tag, that is, a 6-bit DSCP (Differentiated Services Code Point) field is set in the header of the service packet to indicate different service scheduling priorities. When receiving the service, the bearer network device performs service scheduling according to the indicated service scheduling priority according to the DSCP information. Therefore, in the prior art, the service quality requirements of the service itself are discarded, and only the relative quality of service guarantee can be provided.

In the SDN, the flow rules sent by the controller to the switch include information such as flow matching information and content of the operation. The stream matching information is used to uniquely identify different information streams, and the operation content is used to indicate processing of the stream information.

Therefore, in this embodiment, the controller can establish a correspondence between the service identifier and the service quality requirement according to the obtained service identifier and the service quality requirement, and send the packet as a flow rule to the switch. The service identifier can be used as the flow matching information in the flow rule, and the quality of service requirement can be used as the execution operation content in the flow rule. The switch saves the flow rule delivered by the controller to the flow table.

Therefore, when the switch receives the service currently transmitted by the wireless network device, the traffic rule can be matched according to the service identifier of the service. If there is a matching flow rule, the service is scheduled according to the flow rule, and the service quality requirement in this embodiment is The operation content is performed, so the switch specifically schedules the currently transmitted service according to the quality of service requirement. Therefore, the service quality requirements of the service can be effectively met, the effective control of the service quality is realized, and an accurate service quality guarantee is provided.

FIG. 5 is a flowchart of still another embodiment of a service quality control method according to an embodiment of the present disclosure, where the method may include the following steps:

501: The wireless network device determines a quality of service requirement of the currently transmitted service.

502. Determine, according to a correspondence between a preset coding manner and a quality of service requirement, a coding manner corresponding to the quality of service requirement of the currently transmitted service.

503. Generate, according to the coding manner, information about a communication category domain or a service type domain of a data packet network layer header of the current transmission service, where the information of the communication category domain or the service type domain is used to indicate that the bearer network device is configured according to the The corresponding relationship between the preset coding mode and the quality of service requirement is determined, the service quality requirement corresponding to the information of the communication category domain or the service type domain is determined, and the currently transmitted service is scheduled according to the service quality requirement.

When each wireless network device in the wireless network performs service transmission, it needs to bear through the wireless network. The network performs processing such as service scheduling. The bearer network may refer to a network composed of devices connected to each wireless network device in the wireless network, such as a router, a switch, and the like.

Due to different types of services, such as session-based services and background-based services, the requirements for Quality of Service (QOS) may vary.

In the prior art, when a service is transmitted from a wireless network to a bearer network, the service model provided is usually a DiffServ (Differentiated Service) model, and the wireless network device performs scheduling priority marking only on the service based on the DiffServ network technology. A 6-bit DSCP (Differentiated Services Code Point) field is set in the network layer header of the service data packet to indicate different service scheduling priorities. Specifically, when the network layer header of the service data packet is an IPv4 (Internet Protocol Version 4) packet header, the 6-bit DSCP information is a TOS (Type-of-Service, service type) set in the IPv4 packet header. The domain, the TOS field is used to indicate the quality of service that the upper layer protocol expects to process the current datagram, and allocates the datagram according to the importance level, wherein 6 bits of the TOS field are used to indicate the service scheduling priority.

When the network layer header of the service data packet is the IPv6 (Internet Protocol Version 6 network protocol version 6) header, the 6-bit DSCP information is set in the TC (Traffic Class) field of the IPv4 header, and its function is equivalent to IPv4. TOS domain. The 6 bits of the TC field are used to indicate the service scheduling priority.

When receiving the service, the bearer network device performs service scheduling according to the indicated service scheduling priority according to the DSCP information. Therefore, in the prior art, the service quality requirements of the service itself are discarded, and only the relative quality of service guarantee can be provided.

Therefore, in this embodiment, the corresponding coding mode may be set for different service quality requirements in advance. Therefore, when the service quality requirement of the currently transmitted service is determined, according to the correspondence, the coding mode of the current service quality requirement may be determined. The coding mode is information for generating a network layer header TOS domain or a TC domain of a service data packet.

Therefore, the bearer network device can also parse the service quality requirement corresponding to the information of the network layer packet header TOS domain or the TC domain of the service data packet according to the corresponding relationship, and further perform service scheduling according to the service quality requirement.

The quality of service requirements may include information such as service priority requirements, service delay and jitter requirements, service packet loss rate requirements, and service bandwidth requirements.

There are several ways to encode the quality of service requirements. You can use binary values 0 and 1.

In a possible implementation manner, binary values of different preset bit numbers may be used to indicate different quality of service requirements, for example, a binary value of the first preset number of bits indicates a service scheduling priority requirement, and a second preset number of bits is binary. The value indicates the service packet loss rate requirement, and other preset bit number field information may be used to indicate the service delay requirement or the service jitter requirement.
