Problems solved by technology

[0003] However, in the above scheme, as the business load in the network increases, when the network bandwidth is close to saturation, high-priority services will occupy most of the bandwidth resources, and the bandwidth is very limited, so data services with lower priority There is almost no chance to compete for the access channel, resulting in a large number of packets being discarded due to timeout, which seriously degrades the performance of the entire system

Embodiment 1

[0028] see below figure 1 , the service access control method in this embodiment includes:

[0029] 101. Obtain the amount of data transmitted by each service within the preset update time, and determine the bandwidth occupancy parameters of each service within the update time according to the amount of data; wherein, the service can be a service or a service flow. It can be understood that, In practical applications, the business can also adopt other data structure methods, which are not limited here;

[0030] In this step, determining the bandwidth occupancy parameter of each service within the update time according to the amount of data may be: using the amount of data transmitted by the service within the preset update time as the bandwidth occupancy parameter of the service within the update time; or, Use Bandwidth Occupied Time Proportion (BOTP, Bandwidth Occupied Time Proportion) as the bandwidth occupation parameter of the service within the update time, for example, ...

Embodiment 2

[0038] Such as figure 2 As shown, this embodiment provides a service access control method, including:

[0039] 201. Obtain the amount of data transmitted by each service within the preset update time, and determine the bandwidth-to-time ratio of each service within the update time according to the amount of data;

[0040] In this embodiment, the bandwidth-to-time ratio BOTP within the update time is used as the evaluation index of channel access, which is used to reflect the measurement value of the occupation of channel bandwidth resources by various services, so as to determine the distribution of channel bandwidth resources among various service flows. Fairness; in order to calculate the bandwidth-to-time ratio of each service, refer to Formula 1. It is first necessary to determine the total bandwidth occupation time of each service according to the amount of data transmitted by each service within the preset update time and the time required to transmit unit bit data. T...

Embodiment 3

[0059] Such as image 3 As shown, this embodiment provides a service access control method, including:

[0060] 301. Obtain the amount of data transmitted by each service within the preset update time, and determine the bandwidth-to-time ratio of each service within the update time according to the data amount;

[0061] The process of obtaining the bandwidth-to-time ratio in this embodiment is consistent with that in the foregoing embodiments, and will not be repeated here.

[0062] 302. Determine the service with the lowest bandwidth occupancy rate according to the bandwidth-time ratio of each service and the corresponding bandwidth-time ratio threshold;

[0063] In this embodiment, the lowest bandwidth occupancy rate is used as the preset adjustment condition; the way to determine the service with the lowest bandwidth occupancy rate is to calculate the actual bandwidth time ratio of each service compared to BOTP i Compared with the respective preset bandwidth time ratio th...

Abstract

The embodiment of the invention belongs to the communication field and discloses a service access control method, a wireless access system and an access control device which are used for improving system performance. The method of the embodiment comprises the following steps: acquiring the sent data quantity of each service within refresh time, and determining the bandwidth occupation parameter of each service within the refresh time according to the data quantity; determining the service meeting an adjustment condition according to the bandwidth occupation parameter of each service and each corresponding bandwidth occupation parameter threshold; and adjusting the access priority level of the service meeting the adjustment condition. The embodiment of the invention can adjust the access priority levels of different services according to bandwidth occupation ratios, thereby balancing the access priority level of each service, decreasing the packet loss ratios of the services with low priority levels, and improving the system performance.

Description

technical field [0001] The present invention relates to the communication field, in particular to a service access control method, a wireless access system and an access control device. Background technique [0002] With the development of wireless communication technology, the service provided by Wireless Mesh Network (WMN, Wireless MeshNetwork) has developed from the single data service in the past to the multimedia service stage of voice, streaming media and data. Different multimedia services have different requirements for QoS (Quality of Service). For example, voice services and video streaming services are real-time services that have high requirements for network delay, while data services have relatively low requirements for network delay. Much lower; voice and data services have higher requirements on packet loss rate, relatively speaking, video streaming services have lower requirements on packet loss rate. In practical applications, it is necessary to provide di...
