Abstract
Abstract For a virtual connection set up using an asynchronous transmission method which transmits information cells with a rate which is not constant over a relatively long period, the maximum rate may be limited, on the one hand, and the access of the information cells to a trunk line carrying information cells of a plurality of virtual connections may be regulated, on the other hand. As a result, the rate of information cells of a virtual connection is limited.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
205 words
A method for regulating access of data blocks having a predetermined number of data which belong to a plurality of data connections to a trunk line which is used for transporting in time slots in each case one information cell exhibiting a data field accommodating the data block and a header preceding the former which designates the respective data connection in accordance with an asynchronous transmission method, the method comprising the steps of: writing the data blocks into data-connection-individual buffer memories; establishing a respective data block rate for each data connection; providing a counter for each data connection; designating those of the data connections in which the counters are below a predetermined count for forwarding a data block to the trunk line; forwarding a data block from the associated buffer memory to the trunk line for a respective data connection which exhibits a respective lowest count in the current time slot; incrementing the count of the data connection for which a data block is forwarded to the trunk line during a time slot by a value corresponding to the associated data block rate; and decrementing the count of those of the data connections for which no data block is forwarded during a current time slot.
Claim 2
Independent Claim
205 words
A method for regulating access of data blocks having a predetermined number of data which belong to a plurality of data connections to a trunk line which is used for transporting in time slots in each case one information cell exhibiting a data field accommodating the data block and a header preceding the former which designates the respective data connection in accordance with an asynchronous transmission method, the method comprising the steps of: writing the data blocks into data-connection-individual buffer memories; establishing a respective data block rate for each data connection; providing a counter for each data connection; designating those of the data connections in which the counters are below a predetermined count for forwarding a data block to the trunk line; forwarding a data block from the associated buffer memory to the trunk line for a respective data connection which exhibits a respective lowest count in the current time slot; incrementing the count of the data connection for which a data block is forwarded to the trunk line during a time slot by a value corresponding to the associated data block rate; and decrementing the count of those of the data connections for which no data block is forwarded during a current time slot.
Claim 3
Dependent Claim
35 words
The method according to claim 1 further comprising the step of: packeting the data blocks in the data field of an information cell after having been released and before being forwarded to the trunk line.
Claim 4
Dependent Claim
15 words
The method of claim 1 wherein the data blocks are part of an information cell.
Claim 5
Dependent Claim
17 words
The method of claim 1 wherein the same data block rate is defined for each data connection.
Claim 6
Dependent Claim
27 words
The method of claim 1 wherein the data blocks have the same number of data as the data field of an information cell is capable of accommodating.
Claim 7
Dependent Claim
21 words
The method of claim 1 further comprising the step of: storing temporarily the data blocks which have not yet been forwarded.
Claim 8
Dependent Claim
18 words
The method of claim 6 wherein the temporarily stored data blocks are stored separately for each data connection.
