Description

Router-based access user bandwidth adjusting method, device and system

Technical Field

The invention relates to a communication bandwidth technology, in particular to a method, a device and a system for adjusting access user bandwidth based on a router.

Background

In the internet, a Router (Router) is a device that connects each local area network and a wide area network in the internet, and serves as an intermediary between a user and the internet to encapsulate and forward a received data stream, one end of the Router is connected to a user-side communication device, and the other end of the Router is connected to a network-side communication device of a higher-level network, for example, a network control system, to encapsulate a data request or data of the user-side communication device according to a network-side protocol and then send the encapsulated data request or data to the network-side communication device, and to receive data sent by the network-side communication device and send the encapsulated data to the user-side communication device, thereby realizing bidirectional communication between the user-side communication device and the network-side communication device and bidirectional communication between the user-side communication devices. Wherein,

the uplink maximum transmission rate and the downlink maximum transmission rate of the router external network are statically controlled and limited by a network control system of a superior network according to a preset bandwidth allocation rule. The network control system controls the maximum uplink and downlink transmission rates (bandwidth) of the external network of the router corresponding to the lower-level subnet by adopting a static control method according to the total bandwidth provided by the network, and ensures the total bandwidth provided by the network control system, and when all the connected lower-level subnets (routers) reach the maximum transmission rate, the total bandwidth can be larger than or equal to the sum bandwidth of the maximum transmission rates distributed to the routers.

However, in the method for statically allocating the bandwidth of the router, because all routers under the control of the network control system do not work at the allocated maximum transmission bandwidth at the same time, when the transmission rate (bandwidth) of each router controlled by the network control system does not reach the maximum transmission rate (bandwidth), the total bandwidth of the actual transmission rate of each router is smaller than the total bandwidth which can be provided by the network control system, thereby easily causing the waste of the total bandwidth of the network control system; further, the method of statically allocating the bandwidth of the router is adopted, the bandwidth requirement of the user is not considered, for example, in a scene (video downloading, video conversation, etc.) where the user needs a larger bandwidth, the temporary requirement is larger than the static bandwidth allocated to the router, and due to the limitation of static bandwidth allocation, the user cannot acquire a larger bandwidth resource, and cannot meet the personalized bandwidth requirement of the user.

Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

In the existing method for statically allocating the bandwidth of the router, all routers under the control of the network control system cannot simultaneously operate at the maximum statically allocated transmission bandwidth, so that the waste of the total bandwidth of the network control system is easily caused; further, the method of statically allocating the router bandwidth is adopted, the bandwidth requirement of the user is not considered, and the personalized bandwidth requirement of the user cannot be met.

In the embodiment of the invention, the router is provided with a cooperation channel or interface with a broadband operator, when the behavior of a user is found and the user needs a wider broadband, for example, the user starts downloading a large file or watches a high-definition video online, a prompt is popped up to the user, and when the user allows, namely after the user needs to temporarily increase the bandwidth, the router applies for the bandwidth to the broadband operator through the cooperation channel or interface of the operator, so that the router can temporarily increase the bandwidth. Specifically, the router senses the bandwidth demand of a user through automatic or semi-automatic measurement and calculation, dynamically requests a higher uplink and downlink highest transmission rate limit value to the network control system, and the network control system (a superior network) learns that the bandwidth request of the router conforms to a quota policy of the bandwidth of the router through preset overall calculation, so that the higher network bandwidth demand of the inferior router is met under the condition of not wasting the total bandwidth of the network control system.

Fig. 1 is a schematic flow chart of a method for adjusting bandwidth of an access user based on a router according to an embodiment of the present invention. Referring to fig. 1, the process includes:

step 101, acquiring application services operated by a user under the control of a router;

in this step, an application service run by the user that performs data transmission and reception via the router is acquired. After acquiring the bandwidth statically allocated by the network control system according to the prior art, the router provides application service for the user according to the statically allocated bandwidth resource, and the router may be connected to one or more communication devices, which may belong to one or more users.

As an alternative embodiment, before acquiring the application service information run by the user who performs data transceiving via the router, the method further includes:

In this step, when the user uses the application service, the user may actively initiate a bandwidth acceleration request, for example, the user watches a streaming media movie on the communication device on line, and if the playing of the streaming media movie is discontinuous and interrupted, the bandwidth acceleration request may be triggered and generated by a control button preset on the communication device and output to the router.

In the embodiment of the invention, the communication device can be an intelligent terminal device connected with the router, such as an intelligent mobile phone, a notebook computer, a tablet computer, a digital set-top box and the like.

Preferably, the user can also preset an extranet acceleration mode and an acceleration policy in the communication device, wherein,

the extranet acceleration mode includes: the router automatically triggers the acceleration mode and the user actively triggers the acceleration mode. The router automatically triggers the acceleration mode, namely setting the router to automatically monitor and determining whether to carry out the bandwidth acceleration request according to the monitoring result, and the user actively triggers the acceleration mode, namely setting the user to manually trigger whether to carry out the bandwidth acceleration request.

In the embodiment of the invention, a user can preset whether the router is adopted to automatically trigger the acceleration mode or the user actively triggers the acceleration mode in the communication equipment.

The acceleration strategy comprises: a highest bandwidth acceleration setting strategy, an application service white list strategy, an application service black list strategy and the like. The application service blacklist policy is used for setting application services prohibited from being accelerated.

As an alternative embodiment, the external network acceleration mode and the acceleration policy may be set according to the user's habit of using the network application service.

Preferably, after the user sets the external network acceleration mode and the acceleration policy in the communication device, the set external network acceleration mode and the set acceleration policy are output to the router for storage.

Thus, as an alternative embodiment, receiving a bandwidth acceleration request triggered by a user via a communication device includes:

f11, starting the communication device, inquiring the extranet acceleration mode preset by the user, executing step 101 if the extranet acceleration mode is automatically triggered by the router, and executing step F12 if the extranet acceleration mode is actively triggered by the user;

in this step, a corresponding processing method may be adopted according to the extranet acceleration mode set by the user.

F12, the communication device receives a bandwidth acceleration request generated by a user through a preset acceleration control button, queries a stored acceleration policy, determines whether to allow an application service corresponding to the bandwidth acceleration request to accelerate, if so, outputs the bandwidth acceleration request to the router, and executes step 101.

In this step, as an optional embodiment, the communication device may determine whether a preset acceleration control button needs to be loaded in the application service display interface according to the application service type. For example, the data flow corresponding to the application service may be classified into: custom data stream, streaming media data, real-time voice data stream, wireless link control stream, real-time transport protocol stream, background service data stream, and the like. The data types are different and the corresponding guaranteed bandwidths are also different. For example, for QoS data streams such as real-time voice data streams and real-time transport protocol streams, the corresponding guaranteed bandwidth is the lowest bandwidth that satisfies the QoS for the data stream transmission; for non-QoS data streams such as streaming media data, background service data streams and the like, the corresponding guaranteed bandwidth is the lowest bandwidth in the encoding mode. And for application services with large bandwidth required by videos, streaming media and the like, an acceleration control button can be loaded in a corresponding application service display interface. In this way, if the user needs to accelerate the application service, the user can directly click the acceleration control button in the display interface, thereby triggering the generation of the bandwidth acceleration request.

In the embodiment of the present invention, as an optional embodiment, for a situation where a user actively triggers an acceleration mode, for each application service that needs to be accelerated, a bandwidth acceleration request needs to be triggered once.

In the embodiment of the present invention, querying a stored acceleration policy, and determining whether to allow an application service corresponding to a bandwidth acceleration request to be accelerated includes:

In this step, if the acceleration policy is the highest bandwidth acceleration setting policy, the application service white list policy, and the application service black list policy, the application service corresponding to the bandwidth acceleration request is allowed to accelerate as long as the application service corresponding to the bandwidth acceleration request satisfies all the policies.

Of course, in practical application, the user may also directly click an acceleration control button in the display interface, and after triggering generation of the bandwidth acceleration request, the communication device directly outputs the bandwidth acceleration request to the router, where the bandwidth acceleration request carries the application service information.

In the embodiment of the present invention, the application service information includes: the name of the application service, the bandwidth information occupied by the application service, the IP address of the communication device or the router, etc.

102, judging whether each application service operated by a user contains a preset high-bandwidth application service, if so, popping up a prompt to the user, and sending a bandwidth acceleration request to a network control system at a network side through a preset broadband operator interface under the condition that the user allows;

in this step, by discovering user behavior, for example, a user starts a large file download, or watches a high definition video online, a prompt is popped up to the user, and a request is sent and the bandwidth is adjusted under the permission of the user, that is, a bandwidth acceleration request is sent to a network control system provided by a preset broadband operator interface.

In the embodiment of the present invention, the high bandwidth application service includes: the method comprises a large file downloading application service, a large file uploading application service and an online high-definition video application service.

In the embodiment of the invention, the user can realize the sudden demand of the acceleration of the external network in a most convenient way by one-key triggering of the user or automatic triggering of the router, and the acceleration effect of the external network can be ensured not to be diluted and influenced by other equipment.

As an optional embodiment, the router acquires an operator corresponding to the application service, invokes the acquired operator interface, and sends a bandwidth acceleration request to the network control system on the network side.

And 103, adjusting the bandwidth for the high-bandwidth application service corresponding to the bandwidth acceleration request according to the bandwidth information contained in the bandwidth acceleration request response returned by the network control system.

In this step, according to the bandwidth acceleration request response returned by the network control system, the bandwidth is adjusted for the high bandwidth application service corresponding to the bandwidth acceleration request.

After receiving a bandwidth acceleration request response returned by the network control system, the router acquires bandwidth information allocated in the bandwidth acceleration request response, and configures the bandwidth information to a high bandwidth application service corresponding to the bandwidth acceleration request, that is, allocates the bandwidth carried in the bandwidth acceleration request response to the high bandwidth application service on the basis of the bandwidth allocated to the high bandwidth application service.

In this embodiment, as an optional embodiment, after sending the bandwidth acceleration request to the network control system provided by the preset broadband operator interface, the method may further include:

This step is an access user bandwidth adjustment step of the network side based on the router dynamically, and is located between step 103 and step 104.

In this step, after receiving the bandwidth acceleration request, the network control system on the network side acquires the bandwidth information of each router in a timed or non-timed manner, and if the acquired bandwidth of each router is smaller than the preset total bandwidth, adjusts the bandwidth of the corresponding router. That is, after allocating a bandwidth to a router, the router does not necessarily transmit a data stream according to the allocated bandwidth.

In the embodiment of the invention, each router under the control of the network control system can be set to report the bandwidth consumption information of the router at regular time or irregular time, namely the bandwidth information of the operation of the router. In practical application, of course, the network control system may send a bandwidth consumption query request to each router under control after receiving the bandwidth acceleration request, and each router reports the bandwidth information consumed by its own operation to the network control system after receiving the bandwidth consumption query request.

In this embodiment, as an optional embodiment, adjusting the bandwidth for the router corresponding to the bandwidth acceleration request according to the preset total bandwidth and the acquired bandwidth information of the operation of each router includes:

step B11, calculating the sum of the running bandwidths of the routers to obtain the total bandwidth;

in this step, the running bandwidths of the routers are linearly summed.

As an alternative embodiment, calculating the sum of the bandwidths each router operates on includes:

As an alternative embodiment, before calculating the sum of the bandwidths in which the routers operate, the method further comprises:

In this step, if the network control system reserves a part of bandwidth which is not allocated to each router, and if the reserved bandwidth can meet the bandwidth acceleration required in the bandwidth acceleration request, the network control system can directly allocate bandwidth to the router corresponding to the bandwidth acceleration request, so as to reduce the time required by bandwidth allocation and improve the efficiency of bandwidth adjustment. The method comprises the steps of receiving a bandwidth acceleration request, and distributing corresponding acceleration bandwidth for the bandwidth acceleration request from the reserved bandwidth according to the acceleration bandwidth required by an application service data stream in the bandwidth acceleration request, wherein the required acceleration bandwidth is the difference between the guaranteed bandwidth and the running bandwidth.

Preferably, in order to avoid the problem of packet loss of the data stream during the data transmission process due to the fact that the bandwidth of the transmission path of the network control system is completely occupied, so as to improve the reliability and the security of the data stream during data transmission, the method may further include: judging whether the reserved bandwidth is larger than the required acceleration bandwidth, if so, executing a flow of distributing corresponding acceleration bandwidth for the bandwidth acceleration request; otherwise, executing the step of calculating the sum of the running bandwidths of the routers.

As an alternative embodiment, after receiving the bandwidth acceleration request and before applying the acceleration bandwidth required by the service data stream in the bandwidth acceleration request, the method further includes:

and determining the data type corresponding to the requested application service according to the bandwidth acceleration request, and determining the guaranteed bandwidth corresponding to the data stream according to the determined data type.

Step B12, determining that the sum bandwidth is less than the total bandwidth, and calculating the difference between the bandwidth statically allocated by the network control system for the router and the bandwidth operated by the router to obtain the idle bandwidth;

in this step, if the summed bandwidth is equal to the total bandwidth, the bandwidth acceleration request is rejected.

Preferably, as an optional embodiment, after determining that the summed bandwidth is smaller than the total bandwidth, before calculating a difference between a bandwidth statically allocated by the network control system for the router and a bandwidth operated by the router, the method further comprises:

In this step, the bandwidth difference threshold may be determined according to a percentage of the total bandwidth. For example, the bandwidth difference threshold may be determined based on 20%, 10%, or other of the total bandwidth.

Step B13, sorting the idle bandwidths of the routers obtained by calculation according to a sequence from the small order to obtain a sorting queue;

in this step, as an optional embodiment, the idle bandwidths smaller than the preset idle bandwidth threshold may also be disregarded, that is, no sorting is performed, so that the time and consumption required for sorting may be effectively reduced.

In practical applications, the idle bandwidths of the routers may not be sorted in order of decreasing order, and the obtained idle bandwidths may be directly grouped into a pair of columns.

Step B14, sequentially adjusting the router static bandwidth in the sorting queue according to a preset readjustment strategy, and obtaining the reserved bandwidth according to the router static bandwidth before and after adjustment;

in this step, the readjusting policy may be to reserve a part of bandwidth to the router on the basis of the bandwidth in which the router operates, and release the remaining bandwidth to meet the application service requirement that needs to be accelerated by the user after subtracting the reserved bandwidth and the bandwidth in which the router operates from the bandwidth allocated to the router in a static manner.

In the embodiment of the present invention, the calculation formula of the reserved bandwidth may be:

W_iy＝W_iz-ξ*W_ij

in the formula,

W_iyreserving bandwidth for the ith router in the sequencing queue;

W_izstatic bandwidth before adjustment for the ith router in the sorting queue;

xi is an adjustment coefficient, and xi is more than or equal to 1;

W_ijthe operating bandwidth of the ith router in the queue is sorted.

In the embodiment of the invention, xi W_ijThe adjusted static bandwidth for the ith router in the ordering queue.

Step B15, accumulating the reserved bandwidth, determining that the accumulated reserved bandwidth meets the accelerating bandwidth required by the bandwidth accelerating request, and stopping adjusting the router static bandwidth in the sequencing queue;

in this step, the obtained reserved bandwidth of each router is accumulated, whether the accumulated reserved bandwidth meets the acceleration bandwidth required in the bandwidth acceleration request is judged, if not, the calculation of the reserved bandwidth of the router in the sorting queue is returned, that is:

<math> <mrow> <msub> <mi>W</mi> <mi>L</mi> </msub> <mo>=</mo> <munderover> <mi>Σ</mi> <mrow> <mi>i</mi> <mo>=</mo> <mn>1</mn> </mrow> <mi>n</mi> </munderover> <msub> <mi>W</mi> <mi>iy</mi> </msub> <mo>&GreaterEqual;</mo> <msub> <mi>W</mi> <mi>a</mi> </msub> </mrow> </math>

in the formula,

W_Lreserving bandwidth for the accumulation;

n is the accumulated number of routers;

W_athe bandwidth required in the bandwidth acceleration request.

And step B16, allocating bandwidth for the router corresponding to the bandwidth acceleration request according to the acceleration bandwidth required in the bandwidth acceleration request, and adjusting the bandwidth of the corresponding route according to the adjusted static bandwidth.

In this step, after the accumulated reserved bandwidth meets the acceleration bandwidth required in the bandwidth acceleration request, the bandwidth is allocated to the router corresponding to the bandwidth acceleration request according to the acceleration bandwidth required in the bandwidth acceleration request, and the bandwidth of the ith router in the sorting queue is adjusted from the adjusted bandwidth W in step B14_izAdjusted to xi W_ij。

As an alternative embodiment, the method further comprises:

after the application service corresponding to the bandwidth acceleration request is sent and executed according to the adjusted bandwidth, the application service is sent to a router to send a bandwidth recovery request;

and the router sends the bandwidth recovery request to the network control system, and the network control system recovers the bandwidth of the application service into the pre-allocated static bandwidth according to the received bandwidth recovery request.

As another optional embodiment, the bandwidth acceleration request response carries an acceleration duration, and the method further includes:

As an alternative embodiment, the network control system comprises: the system comprises a service provider server, an interconnection starry sky server and a differentiated application control system server. The differentiated application control system server is a control system based on network quality differentiation, and provides a transmission control function based on a strategy to an application layer, so that the application layer can request to reserve a network and does not need to know the underlying transmission network. That is, the differentiated application control system server may evaluate the request of the application layer according to the policy of the operator and reserve a corresponding bandwidth, so that the operator can perform admission control and set an independent bearer media stream policy. Thus, the network side dynamic router-based access user bandwidth adjustment flow is shown in fig. 2.

Fig. 2 is a schematic diagram of a network side dynamic router-based access user bandwidth adjustment process according to an embodiment of the present invention. Allocating bandwidth to the router corresponding to the bandwidth acceleration request according to the acceleration bandwidth required in the bandwidth acceleration request, referring to fig. 2, the process includes:

step 201, a communication device calls an operator interface through a router and sends a bandwidth acceleration request to a service provider server;

in this step, the user selects to use the high bandwidth application, and sends a bandwidth acceleration request using the high bandwidth application to a Service Provider (SP, Service Provider), which carries user information and router information.

In the embodiment of the present invention, the user information may be a user name, an IP address of the communication device, a Media Access Control (MAC) address of the communication device, and the like, and the router information may be an IP address of a router or an MAC address of the router, and the like.

Step 202, the service provider server authenticates the bandwidth acceleration request;

in this step, the SP receives a bandwidth acceleration request for using a high bandwidth application sent by a user, performs bandwidth acceleration request authentication internally, that is, determines whether the user has an authority to use an application service corresponding to the bandwidth acceleration request, and rejects the bandwidth acceleration request of the user if the user does not have the authority to use the application service corresponding to the bandwidth acceleration request, thereby ending the process.

Step 203, after the authentication is passed, sending a bandwidth acceleration request to a connected starry sky (VNET) server;

in this step, the user and the SP are bound, and a bandwidth acceleration request is sent to a virtual network antenna (VNET) server, where the bandwidth acceleration request carries user information and router information bound to the SP.

In the embodiment of the invention, the VNET server is one of Asymmetric Digital Subscriber Line (ADSL) servers, and the SP encapsulates the IP address of the user router and the user name (username) bound with the SP in the bandwidth acceleration request through an interface and sends the bandwidth acceleration request to the VNET server.

Step 204, interconnecting the starry sky servers to perform internal judgment;

in this step, the VNET server performs VNET authentication as middleware. Specifically, the current online broadband user is checked through the router IP or the user IP, and is checked with a user name (username) in a bandwidth acceleration request submitted by the SP, whether the current online broadband user is matched with the user name submitted by the SP is determined, if the current online broadband user is matched with the user name submitted by the SP, the VNET authentication is carried out, and if the current online broadband user is not matched with the user name, the bandwidth acceleration request of the user is rejected. And after passing the authentication, judging whether the current online broadband user is in the speed-up state, and if so, rejecting the bandwidth acceleration request of the user.

Step 205, if the VNET authentication fails, notifying the SP that the speed raising fails;

in this step, if the VNET fails to perform VNET authentication, the SP is notified that the speed cannot be increased; if the current online broadband user is in the speed-up state, the success information is directly returned to the SP.

In the embodiment of the invention, the VNET server stores the speed-up state information of each user, namely whether the VNET server is in the speed-up state or not.

Step 206, if the VNET is successfully authenticated, sending a bandwidth acceleration request to a Differentiated Application Control System (DACS);

in this step, if the VNET is successfully authenticated, an IP/account and acceleration application is submitted to the DACS through the interface.

Step 207, the DACS server returns the acceleration result to the VNET;

in the step, the DACS server processes the bandwidth acceleration request and returns the acceleration result obtained by the processing to the VNET server;

step 208, the VNET server records the user speed-up state;

in this step, the VNET server records that the user starts to use the relevant information of the speed increase.

In step 209, the VNET server returns the speed-up result to the user through the SP.

In this step, the VNET server returns the speed-up result to the SP, and the SP returns the speed-up result to the router after receiving the speed-up result, and the router adjusts the bandwidth currently used by the user according to the bandwidth information corresponding to the speed-up result, so that the bandwidth requirement of the application service is met.
