System, method and record medium for packet transmission capable of reducing delay due to resource assignment
First Claim
1. A packet transmission system in which each terminal unit transmits data to a resource monitoring device of a network for sending the data to another terminal unit via the network, wherein:
- the resource monitoring device includes;
a resource map database for storing a resource map in which central points of resources that can be used by the terminal units are described; and
a resource management means for obtaining the resource map from the resource map database and transmitting the resource map to the terminal units, and each terminal unit includes;
a resource detection means for detecting resource usage statuses of terminal units that are using resources adjacent to a resource used by the terminal unit to which the resource detection means belongs by use of the resource map supplied from the resource monitoring device; and
a resource acquisition means for finding idle resources between the resource used by the terminal unit and the adjacent resources based on the resource usage statuses detected by the resource detection means and acquiring all or part of the idle resources so as to be incorporated in the usable resource of the terminal unit.

Abstract
In a packet transmission system, each terminal unit transmits data to a resource monitoring device of a network for sending the data to another terminal unit via the network. The resource monitoring device includes a resource map database and a resource management section. The resource map database stores a resource map in which central points of resources that can be used by the terminal units are described. The resource management section transmits the resource map to the terminal units. Each terminal unit includes a resource detection section and a resource acquisition section. The resource detection section detects resource usage statuses of terminal units that are using resources adjacent to a resource used by the terminal unit, by use of the resource map supplied from the resource monitoring device. The resource acquisition section finds idle resources between the resource used by the terminal unit and the adjacent resources based on the resource usage statuses detected by the resource detection section, and acquires all or part of the idle resources so as to be incorporated in the usable resource of the terminal unit. By employing such resource assignment, the number of messages necessary for the resource assignment can be reduced and thereby delay time due to the resource assignment can be reduced.

5. A packet transmission method for a packet transmission system in which each terminal unit transmits data to a resource monitoring device of a network for sending the data to another terminal unit via the network, comprising the steps of
a resource map reception step in which each terminal unit receives a resource map in which central points of resources that can be used by the terminal units are described from the resource monitoring device; -
an adjacent resource usage status detection step in which the terminal unit detects resource usage statuses of terminal units that are using resources adjacent to a resource used by the terminal unit by use of the resource map supplied from the resource monitoring device; and
a resource acquisition step in which the terminal unit finds idle resources between the resource used by the terminal unit and the adjacent resources based on the resource usage statuses detected in the adjacent resource usage status detection step and acquires all or part of the idle resources so as to be incorporated in the usable resource of the terminal unit. - View Dependent Claims (6, 7, 8)

9. A machine-readable record medium storing one or more programs for instructing one or more computers to execute a packet transmission method for a packet transmission system in which each terminal unit transmits data to a resource monitoring device of a network for sending the data to another terminal unit via the network, wherein the packet transmission method comprises the steps of:
-
a resource map reception step in which each terminal unit receives a resource map in which central points of resources that can be used by the terminal units are described from the resource monitoring device;
an adjacent resource usage status detection step in which the terminal unit detects resource usage statuses of terminal units that are using resources adjacent to a resource used by the terminal unit by use of the resource map supplied from the resource monitoring device; and
a resource acquisition step in which the terminal unit finds idle resources between the resource used by the terminal unit and the adjacent resources based on the resource usage statuses detected in the adjacent resource usage status detection step and acquires all or part of the idle resources so as to be incorporated in the usable resource of the terminal unit. - View Dependent Claims (10, 11, 12)
