Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
As shown in fig. 1, the system for dynamically selecting a wireless link according to a preferred embodiment of the present invention includes: the system comprises a splitting and aggregating module and a link selecting module; the splitting and aggregating module is connected to the link selecting module, the splitting and aggregating module is in communication connection with an upper layer application through a plurality of first communication interfaces, and the link selecting module is respectively connected to a plurality of wireless links (for example, wireless link 1, wireless link 2 …, wireless link n) through a plurality of second communication interfaces.
The splitting and aggregating module is used for splitting the service data from the first communication interface into data streams according to the transmission capability of the wireless link when the upper layer application sends the service data, wherein each split data stream does not exceed the maximum transmission capability of a single wireless link; the split data stream passes through the link selection module, and the link selection module is used for selecting one or more wireless links with good wireless link states through the second communication interface according to the link transmission states to perform parallel transmission; the splitting and aggregating module is further configured to aggregate the service data from the second communication interface into a data stream that can be recognized by the upper layer application when the upper layer application receives the service data, so as to complete service communication.
Based on the dynamic selection system of the wireless link, the dynamic selection method of the wireless link according to the preferred embodiment of the present invention includes a data sending process and a data receiving process, as shown in fig. 2, a process of sending service data by an upper layer application is shown, and as shown in fig. 3, a process of receiving service data by the upper layer application is shown.
Specifically, as shown in fig. 2, when the upper layer application sends service data, the splitting and aggregating module splits the service data from the first communication interface into data streams according to the transmission capability of a wireless link, where each split data stream does not exceed the maximum transmission capability of a single wireless link; the split data stream passes through the link selection module, and the link selection module selects one or more wireless links with good wireless link states through the second communication interface according to the link transmission states to perform parallel transmission.
The upper layer application is a service server or a client application program.
The first communication interface and the second communication interface are of the same type and belong to the same interface.
The splitting and aggregating module has splitting and aggregating functions, and can split complete data streams and aggregate the split data streams.
The link transmission capacities of the plurality of wireless links are the same or different, that is, each second communication interface is separately connected with one wireless link, and the link capacities may be different.
The link transmission state comprises a time delay state, a received wireless signal strength state or a state of the influence of the comprehensive time delay and the received signal strength, and can also be in a control frame mode, a device active reporting mode and the like; for example, the link transmission state is that the time delays of the link transmission are sorted from small to large (that is, all the wireless links are sorted according to the time delays from small to large), and the link transmission capability of the wireless link with the smaller time delay is better; for example, the link transmission state is that the received wireless signal strengths are sorted from large to small (that is, all the wireless links are sorted from large to small according to the received wireless signal strengths), and the link transmission capability of the wireless link with the larger signal strength is better; for example, the link transmission states are sorted from high to low according to link quality (i.e., all wireless links are sorted from high to low according to link quality) after the effects of time delay and received wireless signal strength are synthesized according to a certain weight, and the higher the link quality is, the better the link transmission capability of the wireless link is.
That is to say, the invention compares the time delay of wireless link transmission or the received wireless signal strength, the smaller the time delay is, the better the signal strength is, or knows the transmission capability of the wireless link by other means (such as control frame, device active reporting, etc.) to determine whether the state of a wireless link is good.
Assuming that a service rate required by the upper layer application is N, a theoretical transmission rate of a radio link is Mn, and N is a number of the radio link, a minimum value Ne = min (Mn) of theoretical transmission rates of all radio links is used as a minimum unit for traffic flow splitting, and the service data from the first communication interface is split into [ N/min (Mn) ] pieces of service data streams, a maximum data transmission capability [ Mi/Ne ], [ ] carried by an ith radio link represents an integer part, Mi refers to an ith radio link, i represents one of N, and [ N/min (Mn) ] pieces of service data streams are used as a minimum unit for traffic scheduling and are scheduled by the link selection module.
For example, taking the example that the Wireless link dynamic selection system is connected to an AP (Wireless Access Point), it is assumed that 4 APs are connected, that is, there are 4 Wireless links (AP 1, AP2, AP3, and AP4, respectively). The 4 link capabilities (theoretical transmission rates) are: m1=400Mbps, M2=500Mbps, M3=1Gbps, M4=2 Gbps. When Ne = min (mn) = min (M1) =400 Mbps.
Existing TCP traffic flow of N =2Gbps is split into [ N/Ne ] =2Gbps/400Mbps =5 traffic data flows, then the first link (AP 1) carries 1 data flow at maximum ([ 400/400] = 1), the second link (AP 2) carries 1 data flow at maximum ([ 500/400] = 1), the third link (AP 3) carries 2 data flows at maximum ([ 1000/400] = 2), and the fourth link (AP 4) carries 5 data flows at maximum ([ 2000/400] = 5); scheduling is carried out according to the state and the bearing capacity of the wireless link; that is, the 5 service data flows are scheduled by the link selection module as a minimum unit of traffic scheduling.
In the invention, Ne is used as a traffic scheduling unit for a data stream, when in an initial state, a wireless link is selected for data transmission according to the time delay of link transmission from small to large or the intensity of a received wireless signal from large to small (or after the time delay and the intensity of the received signal are integrated according to a certain weight and the link quality is from high to low), the data stream is distributed according to [ Mn/Ne ] until all traffic units are distributed, namely [ N/Ne ] service data streams are used as the minimum traffic scheduling unit, and all the service data streams are divided into a plurality of units according to the link state of the wireless link and distributed to the corresponding wireless link for transmission.
And testing the link transmission states of all the wireless links at a certain time interval T, reordering according to the latest test result, and reallocating the data flow units according to the updated ordered list.
When the transmission capability of the wireless link can be known by other means (such as control frame, device active reporting, etc.), assuming that it is Mnow, the traffic units will be allocated according to Mnow/Ne when allocating traffic for the link.
For example, still taking the dynamic selection system of the wireless link to connect with the AP as an example, it is assumed that the delay of 4 links is: t1=1ms, t2=2ms, t3=0.5ms, t4=3ms, in time delay order, resulting in: t3< t1< t2< t 4; the split 5 service data streams are firstly allocated to the AP3 link until the maximum carrying capacity is reached, that is, in this example, [ M3/Ne ] = [1Gbps/400Mbps ] =2 streams are allocated to the AP3 link, and similarly, 1 stream is sequentially allocated to the AP1, 1 stream is allocated to the AP2, and 1 stream is allocated to the AP4, until all traffic units are allocated; if a link with high link bearing capacity exists and the link state is good, the link can be allocated preferentially, and finally a dropped link can occur.
Specifically, as shown in fig. 3, when the upper layer application receives the service data, the service data from the second communication interface is aggregated by the splitting and aggregating module (after a complete data stream is split into multiple pieces, because the incomplete and split data packets are out of order and cannot be identified by the upper layer application, aggregation operation is required) to be a data stream that can be identified by the upper layer application (i.e., a split complete data stream is restored), so as to complete service communication. At this time, the link selection module is not needed, and then the link selection module is not needed, or the link selection module only plays a role of data transmission.
Further, when the transmission capability of the wireless link changes dynamically, the splitting and aggregating module updates the splitting and aggregating operation of the data service according to the link state within a certain time window.
The invention can dynamically adjust the number of the data streams carried by each wireless link by detecting the state of the wireless link and according to the result of the link state parameter sequencing, can support the splitting and merging of the application flow, and distributes the split flow to different wireless links for parallel transmission.
The data stream of the wireless link level is split, and the parallel transmission of a plurality of wireless links can be realized; compared with the core network side which is used for load balancing, the method can only split according to different streams generated by the application, and the splitting of the data stream at the access network side can be more matched with the bearing capacity of a communication link without other adaptations at the application side. The aggregation of data flows at a wireless link level and the aggregation of wireless links realized by an access network side also break through the limitation that the load balance of a core network side needs the same wireless transmission equipment and the performance is close to the same, and support the connection of the existing wireless equipment. The new data flow scheduling method based on the system supports the dynamic scheduling of the data flow, fully matches and utilizes the wireless link resource.
In summary, the present invention provides a method and a system for dynamically selecting a wireless link, where a plurality of first communication interfaces are in communication connection with an upper application, a plurality of second communication interfaces are respectively connected with a plurality of wireless links, service data sent by the upper application is transmitted to a splitting and aggregating module through the first communication interfaces, the splitting and aggregating module splits the service data into data streams according to transmission capabilities of the wireless links, each split data stream does not exceed the maximum transmission capability of a single wireless link, the split data streams pass through a link selection module, and the link selection module selects one or more wireless links with good wireless link status for parallel transmission, that is, selects a second communication interface with good wireless link status to send data; when receiving the service data, the service data from the second communication interface is aggregated into the data stream recognizable by the upper application through the splitting and aggregating module, and the service communication is completed. The invention can dynamically adjust the number of the data streams carried by each wireless link by detecting the state of the wireless link and according to the result of the link state parameter sequencing, can support the splitting and merging of the application flow, and distributes the split flow to different wireless links for parallel transmission.
