Abstract
Abstract The invention relates to a local area network operating in the asynchronous transfer mode, with a first transceiver (1 to 8, 54 to 57) which includes a radio device (33, 60) for transmitting cells to a plurality of other transceivers (1 to 21, 54 to 57). For a data exchange between the first and the other transceivers (1 to 21, 54 to 57) without cells being blocked, a radio device (49, 60) includes a first buffer memory (73) assigned to a respective other transceiver (1 to 21, 54 to 57). A first buffer memory (73) is used for storing a cell whose destination is another transceiver (1 to 21, 54 to 57) which is assigned to the respective first buffer memory (73).

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
96 words
A local area network operating in the asynchronous transfer mode, with a first transceiver (1 to 8, 54 to 57), which transceiver includes a radio device (33, 60) for transmitting cells to a plurality of other transceivers (1 to 21, 54 to 57), characterized in that the radio device (49, 60) includes first buffer memories assigned to another transceiver (1 to 21, 54 to 57) and in that a first buffer memory stores a cell whose destination is another transceiver (1 to 21, 54 to 57) which is assigned to the respective first buffer memory (73).
Claim 2
Dependent Claim
96 words
A local area network operating in the asynchronous transfer mode, with a first transceiver (1 to 8, 54 to 57), which transceiver includes a radio device (33, 60) for transmitting cells to a plurality of other transceivers (1 to 21, 54 to 57), characterized in that the radio device (49, 60) includes first buffer memories assigned to another transceiver (1 to 21, 54 to 57) and in that a first buffer memory stores a cell whose destination is another transceiver (1 to 21, 54 to 57) which is assigned to the respective first buffer memory (73).
Claim 3
Dependent Claim
51 words
The local area network as claimed in claim 1, characterized in that the radio device (49, 60) comprises a first controller (75) which is used for deleting a cell in a first buffer memory (73) after an assigned receiver device (1 to 21, 54 to 57) has acknowledged a proper reception.
Claim 4
Dependent Claim
117 words
A local area network as claimed in claim 2, characterized in that after a cell has been written into a first buffer memory (73), the first controller (75) is used for sorting the cells in the respective first buffer memory (73) in dependence on the residual lifetime, in that the first controller (75) is used for computing the residual lifetime of a cell by subtracting the instant at which the computation takes place and adding the instant at which the storage of the predefined maximum dwell time takes place and in that the first controller (75) is used for releasing the reading of the cell that has the shortest residual lifetime from a first buffer memory (73).
Claim 5
Dependent Claim
61 words
The local area network as claimed in claim 3, characterized in that the first controller (75) is not used for sorting such cells for which an acknowledgement of the reception within a time-out has not yet arrived after the cells have been read from a first buffer memory (73), or when the waiting period for an acknowledgement has not yet elapsed.
Claim 6
Dependent Claim
57 words
The local area network as claimed in claim 4, characterized in that a second buffer memory (79) is used for receiving a cell read from a first buffer memory (73) and in that a second controller (81) is used for sorting the cells buffered in the second buffer memory (79) as a function of the residual lifetime.
Claim 7
Dependent Claim
83 words
The local area network as claimed in claim 5, characterized in that the second controller (81) is used for counting the cells to be transmitted to a transceiver (1 to 21, 54 to 57) and for transporting them to a control device (1 to 8, 54 to 57), and in that the control device (1 to 8, 54 to 57) is used for assigning the number of cells which are to be transmitted to a specific transceiver (1 to 21, 54 to 57).
Claim 8
Dependent Claim
82 words
The local area network as claimed in claim 1, characterized in that the transceivers (54 to 57) form each a terminal comprising a station (58) and a network interface (59), which network interface (59) comprises a controller (61) provided at least for the connection set-up and a switching device (62) for switching cells between radio device (60), station (58) and controller (61), and in that the terminals (54 to 57) are used for directly exchanging data with another terminal (54 to 57).
Claim 9
Dependent Claim
108 words
The local area network as claimed in claim 1, characterized in that a plurality of transceivers are arranged as network interfaces (1 to 8) which are coupled with a plurality of other network interfaces (1 to 8) to a ring, in that a network interface (1 to 8, 23) comprises a controller (40) provided at least for setting up the connection and a switching device (24) for switching cells between ring connections (29 to 32), a radio device (33) and a controller (40), and in that other transceivers (9 to 21) form each a terminal which is used for exchanging data with a network interface (1 to 8).
Claim 10
Dependent Claim
102 words
A radio device (33, 60) of a first transceiver (1 to 8, 54 to 57) in a local area network operating in the asynchronous transfer mode, for transmitting cells to a plurality of other transceivers (1 to 21, 54 to 57), characterized in that the radio device (49, 60) comprises a first buffer memory (73) assigned to a respective other transceiver (1 to 21, 54 to 57) and in that a first buffer memory (73) is used for storing a cell whose destination is another transceiver (1 to 21, 54 to 57) which is assigned to the respective first buffer memory (73).
Claim 11
