Problems solved by technology

In this way, when the AFR of a certain user is higher than the PFR, no user can use the remaining bandwidth obtained by subtracting the PFR from the AFR, and a problem arises that the line bandwidth cannot be effectively used.

Embodiment Construction

[0017] figure 1 A configuration example of a packet relay device including a shaping device is shown.

[0018] The packet relay device is composed of a plurality of line IF (interfaces) 50 each having at least one shaping device 10 , a plurality of routing processing units 30 and at least one switch 60 .

[0019] Each line IF50 is connected to one or more lines. The line IF50 includes a physical layer corresponding unit to be described later, and frames (packets) are input and output from the connected line through the physical layer corresponding unit. The routing processing unit 30 is connected to one or more lines IF50 and switches 60 . The routing processing unit 30 receives a frame from the connected line IF50, determines the route of the frame based on the destination address of the data included in the frame, and forwards the frame via the switch 60 or which line IF50. Also, the switch 60 receives a frame from the routing processing unit 30 and forwards the frame to ...

Abstract

A traffic shaping apparatus calculates a minimum transmission interval, an allowed transmission frame rate of a user frame, and a reference transmission interval for each user according to a minimum transmission frame rate and a peak transmission frame rate specified for each user. The traffic shaping apparatus also calculates a first estimated transmission time according to the reference transmission interval, and a second estimated transmission time according to the minimum transmission interval for each user. The traffic shaping apparatus determines the user having the earliest first estimated transmission time, and determines according to the second estimated transmission time of the user whether a user frame is to be transmitted.

Description

technical field [0001] The invention relates to a traffic shaping method and a traffic shaping device. In particular, the present invention relates to a traffic shaping method and a traffic shaping device for effectively utilizing bandwidth according to changes in bandwidth used by users. Background technique [0002] Generally, when communicating via a public network (or a public line), the user must sign a contract with the manager of the public network on the transmission bandwidth or the priority of frame (packet) forwarding before starting the communication. After the contract between the user and the public network manager is established, the user's terminal starts to forward frames to the public network. On the other hand, the relay device located on the manager side of the public network entrance monitors the transmission bandwidth of the terminal, and if it exceeds the transmission bandwidth stipulated in the contract, it lowers the priority of the frame of the vio...
