[Prior art]
In recent years, with the widespread use of always-on and broadband networks, not only text-based content but also multimedia content such as music and video has been actively distributed on the network. Various service forms such as stream mink and download of these contents are mixed on the band.
[0003]
In order to realize various forms of content distribution on such a network, research and development of QoS technology is currently active.
[0004]
[Problems to be solved by the invention]
However, in the conventional QoS technology related to bandwidth control, there are many methods in which a policy is statically determined, and bandwidth control cannot be performed dynamically by a user operation according to user needs. For example, when a user is simultaneously enjoying various services such as downloading music content, Web browsing, and streaming video content, it is not possible to easily designate the service that the user wants to realize quickly in real time.
[0005]
The present invention was devised in view of the above-mentioned problems, and the object of the present invention is to perform dynamic downlink bandwidth control by a user operation according to the user's needs and to the user. It is to provide a visual and dynamic downlink bandwidth control system capable of operating the control at the time of visual recognition.
[0006]
[Means for Solving the Problems]
The present invention is, traffic that contains an application control means for controlling the application, and downstream tolerance band monitoring means to measure the downlink tolerance band between a terminal and a server and a router, the downstream band priority for each traffic A priority DB (database), data reception control means for determining a downlink request bandwidth for each traffic at that time based on the traffic priority DB and the downlink allowable bandwidth value obtained by the downlink allowable bandwidth monitoring means; And an input / output I / F connected to a network.
[0007]
A step of registering a traffic priority in the traffic priority DB in advance, a step in which an application control unit makes a data reception request, a step of measuring a permissible downlink bandwidth between the terminal, the server, and the router; The method includes the steps of estimating a requested transfer rate for each traffic based on priority, and receiving individual traffic at the estimated requested transfer rate.
[0008]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings for understanding of the present invention. It should be noted that the following example is an example embodying the present invention, and does not limit the technical scope of the present invention. The network described here assumes various networks such as the Internet and a home network.
[0009]
First, Example 1 will be described with reference to FIGS. 1 and 4. Here, FIG. 1 is a block diagram showing a configuration of a visual and dynamic downlink bandwidth control system according to the first embodiment, and FIG. 4 is a visual and dynamic downlink bandwidth control system according to the first embodiment. It is a flowchart which shows the process sequence of.
[0010]
First, the user uses the monitor 201 to register the traffic priority in the traffic priority DB 210 in advance. As shown in FIG. 6, the priority of the user-desired downlink usage band is set for traffic characteristic items such as streaming, download, file transfer, and HTML document acquisition.
[0011]
Hereinafter, a processing procedure in the case where the user simultaneously enjoys two types of services such as downloading of contents and acquisition of HTML documents will be described. Here, the service received from the server A301 is service A (server address: address A, port number: A port), and the service received from the server B302 is service B (server address: address B, port number: B port). The traffics are traffic A and B, and the traffic priorities stored in the traffic priority DB 210 are α and β.
[0012]
First, the application control unit 202 requests services A and B.
[0013]
First, the allowable downlink bandwidth monitoring unit 204 communicates only with the server A301 and measures the allowable downlink bandwidth between the terminal and the server A301 (assuming that the allowable downlink bandwidth is Xa here). Next, the allowable downlink bandwidth monitoring unit 204 communicates only with the server B302 and measures the allowable downlink bandwidth between the terminal and the server B302 (here, the allowable downlink bandwidth is Xb (Xa ≧ Xb)). ). Finally, the allowable downlink bandwidth monitoring unit 204 communicates with the router 303 to measure the allowable downlink congestion area between the terminal and the router 303 (where the allowable downlink bandwidth is X (X ≧ Xa ≧ Xb)). ).
[0014]
Next, based on the result (X, Xa, Xb) and the priorities (α, β) of the traffic A and B stored in the traffic priority DB 210, the data reception control unit 203 performs the following: In addition, the downstream bandwidth required from the terminal side for the traffic A and B is estimated (see FIGS. 2 and 3).
i) When αX / (α + β) ≧ Xa and βX / (α + β) ≧ Xb: Xa for server A, Xb for server B
ii) If αX / (α + β) ≧ Xa and βX / (α + β) <Xb: Xa for server A, and
ii-i) When X ≧ (Xa + Xb): Xb for server B
ii-ii) When X <(Xa + Xb): X-Xa with respect to server B
iii) If αX / (α + β) <Xa and βX / (α + β) ≧ Xb: Xb for server B, and
iii-i) When X ≧ (Xa + Xb): Xa for server A
iii-ii) If X <(Xa + Xb): X-Xb for server A
iv) When αX / (α + β) <Xa and βX / (α + β) <Xb: αX / (α + β) for server A, βX / (α + β) for server B
Then, based on the above result, the data reception control unit 203 issues an instruction to the server so that each traffic can be received with these bandwidths. For example, it instructs the address A and the port number A of the server A301 communicating with the terminal to transmit data at a desired transfer rate. Here, a series of flows in which the downlink allowable bandwidth monitoring unit 204 measures the downlink allowable bandwidth and sets the requested transfer rate for each traffic based on the result and the traffic priority, the network status is constantly changing. Since it is different, it should be performed regularly and reflect real-time characteristics.
[0015]
Finally, it becomes possible to acquire desired data from the server via the input / output I / F 205 in a user desired band.
[0016]
Next, Example 2 will be described based on FIGS. 1 and 5. Here, FIG. 1 is a block diagram showing a configuration of a visual and dynamic downlink bandwidth control system according to the second embodiment, and FIG. 5 is a visual and dynamic downlink bandwidth control system according to the second embodiment. It is a flowchart which shows the process sequence of.
[0017]
In the following, a processing procedure in the case where the first embodiment has already been executed and it is desired to change the downlink use band for each traffic on the way will be described.
[0018]
As shown in FIG. 7, the user shifts the current downlink usage bandwidth for each traffic visually displayed on the monitor 201 by moving the bar shown in FIG. The desired bandwidth can be reset with a simple operation. For example, as shown in FIG. 7, when the user wants to download faster than the acquisition of an HTML document, the user can easily set to widen the download bandwidth. Here, the movable range of the bar in FIG. 7 is according to the table of FIG.
[0019]
Next, the bandwidth change by the above-described user operation is performed by updating the traffic priority DB 210, and based on the updated traffic priority and the downlink allowable bandwidth value obtained by the downlink allowable bandwidth monitoring unit 204. The data reception control unit 203 again estimates the traffic request transfer rate and issues an instruction to the address and port number of the server communicating with the terminal.
[0020]
Then, by acquiring data from the server at a new traffic request transfer rate via the input / output I / F 205, it is possible to acquire each data in a band desired by the user during operation. In addition, the user can visually control the bandwidth, and the user's needs can be reflected immediately.
[0021]
【The invention's effect】
As described above, according to the present invention, in a network in which various service forms are mixed, the user can dynamically control the downstream band according to the user's own operation by the user's own operation. Moreover, user needs can be easily reflected by visually presenting the control method to the user.
