Abstract
The invention discloses means and methods for transmission of information in paths of an ATM network wherein a path setup for at least one new path in the network is initiated if the path capacity currently used for transmission of information exceeds a threshold, wherein a path release for at least one path in the network is initiated if the path capacity currently used for transmission of information is below a threshold.
Claims31
Method for transmission of information in paths of an ATM network
- wherein a path setup for at least one new path in the network is initiated if the path capacity currently used for transmission of information exceeds a threshold (FIG. 14, setup threshold),
- wherein a path release for at least one path in the network is initiated if the path capacity currently used for transmission of information is below a threshold (FIG. 14, release threshold).
Method according to any of the preceding claims characterized in that the setup threshold and/or the currently used path capacity represents accumulated cell rates.
Method according to any of the preceding claims characterized in that the thresholds and/or the currently used path capacity represent
- the number of currently used ATM-channels in one path or in more than one path or in all paths.
Method according to any of the preceding claims characterized in that the thresholds are preset values.
Method according to any of the preceding claims characterized in that the thresholds are variable values that are administrated by the network.
Method according to any of the preceding claims characterized in that the network is an ATM-AAL2 network.
Method according to any of the preceding claims characterized in that the setup threshold exceeds the release threshold.
Method according to any of the preceding claims characterized in that after setup of a path, ATM-channels can be assigned to the path.
Method according to any of the preceding claims characterized in that the path capacity currently used for transmission of information is the current traffic in either one path or all currently used paths.
Method according to any of the preceding claims characterized in that the setup and/or release threshold represents a minimum or maximum of a distance between currently used network resources and all available path resources.
Method according to any of the preceding claims characterized in that a path is an ATM-VCC (ATM virtual channel connection).
Method according to any of the preceding claims characterized in that a channel is an AAL2 channel.
Method according to any of the preceding claims characterized in that after a setup of more than one path, a path is respectively occupied completely with ATM-channels before starting to occupy an other path with ATM channels.
Method according to any of the preceding claims characterized in that a path release for at least one path in the network is initiated only if the path capacity currently used for transmission of information is below a threshold during at least a preset period of time or if it is on the average below a threshold during at least a preset period of time.
Device for transmission of information in paths of an ATM network
- with means for storing thresholds
- with means for determining the path capacity currently used for transmission of information
- with means for comparing the determined path capacity currently used for transmission of information and at least one stored threshold
- with means (FIG. 10/SVC control;
- access manager) that are designed for initiating a path setup for at least one new path in the network if the path capacity currently used for transmission of information exceeds a threshold (FIG. 14, setup threshold),
- with means that are designed for initiating a path release for at least one path in the network if the path capacity currently used for transmission of information is below a threshold (FIG. 14, release threshold).
