their locations. It isolates the LANs from each other, allowing both sides to pass traffic internally. If a transmission from one LAN is addressed to a node on the other LAN, the bridge transmits it onto the other LAN for the destination node.

Broadcast address

The station address FFFFFF-FFFFFF. Packets intended for all nodes on a LAN use this address as the destination address.

Broadcast packet

A packet sent to all nodes on a LAN.

Cell

A cell is a fixed-length packet of bytes.

Cell Delineation

Cell delineation is the process of identifying the beginning of cells. This can be based on the HEC byte of individual ATM cells.

Cell Layer

A cell layer is the layer where cell level management, routing, traffic control and multiplexing happen.

Cell Loss Priority (CLP)

CLP is a 1-bit field in the fourth byte in the header of an ATM cell. It is used to set priorities for cell discarding. A CLP value of 0 gives the cell a 'higher priority' telling the network this cell should not be discarded. A CLP value of 1 assigns the cell a 'lower' priority informing the network that this cell can be discarded depending on traffic conditions.

Cell Payload

A field of 44, 47, or 48 bytes in an ATM cell that carries service data.

Cell Segmentation

The process of mapping a service into an ATM cell stream.

Cell Stream

A continuous signal of ATM cells. Also known as stream.
