| 摘要 |
The invention relates to a local network operating in the asynchronous transfer mode (ATM), comprising a plurality of stations which are coupled, via network interfaces comprising a coupling device and a control arrangement, to sending and receiving ring lines and which are provided for transmitting user cells containing user-oriented information and at least control cells containing signalling information. The control arrangement assigned to a transmitter station is provided for generating at least a control cell to be sent to a receiver station after the control arrangement has received from the transmitter station a control cell with a realisable request for a unicast or multicast connection from a user of the transmitter station to a user of at least one receiver station, which control cell has in its information field at least information about the users, the address of the transmitter station and a user-related identification for a down channel. At least one control arrangement assigned to a receiver station is provided for generating a control cell to be transmitted to the transmitter station after a transmitter station-originated control cell containing a realisable connection request from a user of the receiver station has been received, which control cell contains in its information field at least an indication about the address of the assigned receiver station and a user-related identification for the up-channel.
