A data communication switch receives packets having first priorities, generates second priorities as a function of the first priorities, prioritizes selected ones of the plurality of packets as a function of the second priorities and transmits the plurality of packets having the second priorities. The first priorities may be inbound Std. 802.1Q tag priorities and the second priorities may be regenerated Std. 802.1Q tag priorities. Priority selection may be communicated in the switch through the expedient of packet marking. Marks may be instantiated in the packets prior to subjecting the packets to prioritization on the switch and removed from the packets prior to transmitting the packets from the switch. The switch may be arranged to prioritize selected ones of 802.1Q-complaint tagged packets based on a tag priority while preserving tag priority signaling for all such tagged packets.
The invention relates to an exchange for a telecommunication network, with a message/dialogue device, whereby said message/dialogue device, comprises one interface each for a packet-oriented data transmission network and a line-oriented data transmission network and a virtual port for controlling the message/dialogue device, by means of a connection running through the packet-oriented data transmission network, for the transmission of messages and/or dialogues to a user.
Disclosed is a bridge apparatus for the relay of a frame between a wire LAN and a wireless LAN. When a frame transmitted by the wire LAN is a specific frame, a QoS middleware unit of the bridge apparatus adds a bridging request to an FIFO queue having a high priority. And when the frame received from the wire LAN is not a specific frame, the QoS middleware unit adds a bridging request to an FIFO queue having a low priority. A bridging unit performs the priority processing for the bridging request present in the FIFO queue having a high priority, and transmits the frame to the wireless LAN.
