Fig. 1 is a flow chart of a sub-stream resource scheduling method according to an embodiment of the present application.
As shown in fig. 1, the sub-stream resource scheduling method includes:
step 101, a plurality of service requests are received.
Step 102, determining service priorities of the plurality of service requests.
In practical application, one or more service requests sent by the terminal, such as video playing, live broadcasting, information browsing, etc., may be responded, and it may be understood that different services are different in priority levels corresponding to processing, for example, the following are illustrated:
in a first example, a service type, such as a real-time service, a non-real-time service, etc., of a plurality of service requests is determined, and the plurality of services are ordered according to the service type to generate a plurality of service priorities.
In a second example, service types and service processing preferences of the plurality of service requests are determined, service priorities of the plurality of services are ordered according to the service types and the service processing preferences, and a plurality of service priorities are generated, so that personalized processing requirements of users are further improved.
Step 103, calculating a quality index value corresponding to each of the current multiple sub-streams according to the preset dimension parameters.
Specifically, each dimension parameter may be preset to calculate the sub-stream according to the need, so as to obtain a quality index value corresponding to each sub-stream, where the quality index value is a quantized representation of a state and quality of the sub-stream, and there are various ways of calculating the quality index value corresponding to each sub-stream in the current multiple sub-streams according to the preset dimension parameter, for example, the following methods are:
in a first example, a sub-stream back-off delay value and a sub-stream packet loss rate corresponding to each sub-stream are obtained, a first weight corresponding to the sub-stream back-off delay value and a second weight corresponding to the sub-stream packet loss rate are determined, and the sub-stream back-off delay value, the first weight, the heavy sub-stream packet loss rate and the second weight are processed through a preset formula to generate a quality index value corresponding to each sub-stream.
It should be noted that, the sum of the first weight and the second weight is 1, and the first weight and the second weight value can be adjusted according to the actual application requirement
In a second example, a sub-stream back-and-forth delay value, a sub-stream packet loss rate, a sub-stream connection success rate and a sub-stream throughput corresponding to each sub-stream are obtained, a first weight corresponding to the sub-stream back-and-forth delay value, a second weight corresponding to the sub-stream packet loss rate, a third weight corresponding to the sub-stream connection success rate and a fourth weight corresponding to the sub-stream throughput are determined, and the sub-stream back-and-forth delay value, the first weight, the heavy sub-stream packet loss rate, the second weight, the sub-stream connection success rate, the third weight, the sub-stream throughput and the fourth weight are processed through a preset formula to generate a quality index value corresponding to each sub-stream.
It should be noted that, the sum of the first weight, the second weight, the third weight and the fourth weight is 1, and the values of the first weight, the second weight, the third weight and the fourth weight can be adjusted according to the actual application needs.
And 104, determining a service scheduling strategy according to the quality index value and the service priority corresponding to each sub-stream, and scheduling a plurality of services according to the service scheduling strategy.
Specifically, after determining the quality index value corresponding to each sub-stream, and determining the state and quality of each sub-stream, it may be determined how to allocate the sub-streams for traffic transmission in combination with a plurality of traffic priorities.
As one possible implementation manner, the priority level ranks of the services are determined according to the priorities of the services, the quality ranks of the sub-flows are determined according to the quality index values corresponding to the sub-flows, the sub-flow with the highest quality rank is used for transmitting the service with the highest level rank, and the transmission of the service is advanced.
For example, determining the highest priority service according to the priorities of the services, determining a first target substream corresponding to the highest quality index value according to the quality index value corresponding to each substream, if the first target substream can complete service transmission of the highest priority service, calling the first target substream to perform service transmission of the highest priority service, and if the first target substream can not complete service transmission of the highest priority service, determining a second target substream corresponding to the next highest quality index value according to the quality index value corresponding to each substream, and calling the first target substream and the second target substream to perform service transmission of the highest priority service.
As another possible implementation manner, the service N before the service level ordering and the sub-stream N before the quality index value ordering are directly obtained, and each sub-stream is randomly selected to perform service transmission for each service, thereby ensuring that the service priority processing needs to be processed in time.
According to the sub-stream resource scheduling method, service priorities of a plurality of service requests are determined by receiving the plurality of service requests, quality index values corresponding to each sub-stream in the current plurality of sub-streams are calculated according to preset dimension parameters, a service scheduling strategy is determined according to the quality index values and the service priorities corresponding to each sub-stream, and a plurality of services are scheduled according to the service scheduling strategy. Therefore, the quality index value of the current sub-stream is determined based on the multidimensional parameter, the sub-stream is determined to be transmitted as the service according to the quality index value, and when a plurality of services work simultaneously, different services are scheduled to the optimal sub-stream transmission by taking the service priority and the quality index value as references, so that the overall service quality of the network is ensured, and the user Internet surfing experience is improved.
Fig. 2 is a flow chart of another method for scheduling seed-stream resources according to an embodiment of the present application.
As shown in fig. 2, the sub-stream resource scheduling method includes:
step 201, a plurality of service requests are received, and service types and service processing preference degrees of the plurality of service requests are determined.
And 202, sorting the service priorities of the plurality of services according to the service types and the service processing preference, and generating service priorities of the plurality of service requests.
In practical application, the scene of multi-service competition sub-stream resources is rarely considered, and differentiated analysis of services is lacking, so that a reasonable service scheduling transmission strategy based on the multi-service scene is lacking, and therefore, the services need to be analyzed.
Specifically, different services have differentiation characteristics, from the delay dimension, the services can be divided into real-time services and non-real-time services, such as video conferences, live services and the like, while most of common text services are non-real-time services, so that high-reliability low-delay transmission of the real-time services is ensured as much as possible, i.e. the real-time services have higher scheduling and resource priority.
It can be understood that the attention degree and preference degree of different users on different services are different, so that the services also have priority characteristics from the user experience dimension, the service priorities can be comprehensively judged and ranked based on the dimensions, and therefore, the services can be ranked according to the service types and the service processing preference degree to generate the service priorities.
Step 203, obtaining the reverse delay value, the packet loss rate, the connection success rate and the throughput of each sub-stream.
Step 204, determining a first weight corresponding to the sub-stream back-off delay value and a second weight corresponding to the sub-stream packet loss rate.
Step 205, determining a third weight of connection success rate with the sub-stream and a fourth weight of throughput with the sub-stream; wherein the sum of the first weight, the second weight, the third weight and the fourth weight is 1.
And 206, processing the sub-stream round trip delay value, the first weight, the heavy sub-stream packet loss rate, the second weight, the sub-stream connection success rate, the third weight, the sub-stream throughput and the fourth weight through a preset formula to generate a quality index value corresponding to each sub-stream.
Specifically, first, one or more of dimension parameters capable of characterizing sub-stream quality, such as a sub-stream back-off delay value RTT, which is a key indicator characterizing data transmission delay, a sub-stream packet loss rate, a sub-stream connection success rate, and a sub-stream throughput are determined, where the quantized value of RT of a sub-stream is assumed to be
It can be understood that the sub-stream congestion index can represent the current congestion degree of the sub-stream, if the service is transmitted in the sub-stream with high congestion, the transmission reliability of the service will be greatly reduced, i.e. the situation of packet loss, data transmission blocking, etc. will occur with high probability, where the sub-stream packet loss rate is taken as the parameter for balancing the congestion degree of the sub-stream, and it is assumed that the sub-stream packet loss rate is Los i 。
It can be understood that the establishment of the sub-stream is based on the handshake mechanism, after the sub-stream is successfully established, the service can be served and the data transmission can be performed, so that the success rate of the sub-stream establishment is also required to be used as a key index, and the sub-stream connection success rate is assumed to be Set i 。
It can be understood that the sub-stream throughput is a key indicator of the sub-stream transmission capability, and that the high throughput sub-stream can transmit high-traffic with high quality, such as real-time video traffic, while ensuring that the traffic is transmitted quickly with high reliability, whereas the low throughput sub-stream is in the following conditionThere is a large limitation in transmitting traffic, assuming that the throughput of the sub-stream is Thr i 。
That is, the four dimension parameters of the sub-stream forward and backward delay value, the sub-stream packet loss rate, the sub-stream connection success rate and the sub-stream throughput can embody the state and the quality of the sub-stream from different latitudes, and the dimension parameters are fused, so that the quality of the current sub-stream can be measured more comprehensively and more accurately.
Therefore, assume that the weighting factors of the four dimensional parameters are θ 1 ,θ 2 ,θ 3 ,θ 4 The sum of the first weight, the second weight, the third weight and the fourth weight is 1, and the quality index value of the sub-stream may be represented by the following formula:
the first weight, the second weight, the third weight and the fourth weight can be selected and adjusted according to the requirement.
Step 207, determining the highest priority service according to the service priorities, and determining the first target substream corresponding to the highest quality index value according to the quality index value corresponding to each substream.
In step 208, if the first target sub-flow can complete the service transmission of the service with the highest priority, the first target sub-flow is invoked to perform the service transmission of the service with the highest priority.
Specifically, the highest priority service occupies the highest quality sub-stream resource for service transmission, when the highest quality sub-stream resource is insufficient to meet the transmission scheduling requirement of the highest priority service, the next highest quality sub-stream resource can be allocated to the highest priority service at the same time, that is, if the first target sub-stream can not complete service transmission of the highest priority service, the second target sub-stream corresponding to the next highest quality index value is determined according to the quality index value corresponding to each sub-stream, and the first target sub-stream and the second target sub-stream are called to carry out service transmission of the highest priority service.
It may be further understood that when the highest quality sub-stream resource meets the transmission scheduling requirement of the highest priority service and there are more resources remaining, the next highest priority service may perform service transmission on the high quality sub-stream at the same time, that is, after the first target sub-stream is invoked to perform service transmission on the highest priority service, it is determined whether there is a remaining first target sub-stream, and if there is a remaining first target sub-stream, the first target sub-stream is invoked to perform service transmission on the next highest priority service.
When the highest quality sub-stream resource meets the transmission scheduling requirement of the highest priority service and the resource surplus is less, the sub-high quality sub-stream is distributed to the sub-high priority service, when a plurality of services work simultaneously, different services are scheduled to the optimal sub-stream transmission by taking the service priority and the sub-stream state as the reference, so that the overall service quality of the network is ensured, and the user surfing experience is improved.
In the embodiment of the application, the quality index value of the current sub-stream can be determined based on the multidimensional parameter, and the sub-stream is determined to be the service for transmission according to the quality index value, in addition, when a plurality of services work simultaneously, different services are scheduled to the optimal sub-stream for transmission by taking the service priority and the sub-stream state as the reference, so that the overall service quality of the network is ensured, and the user Internet surfing experience is improved.
