bandwidth | The width of a communications channel measured in Hertz - cycles |
| per second. In digital communications, bandwidth is measured in |
| bits per second (bps). |
BB_Credit | Buffer to Buffer Credit, a flow control method that maintains |
| counters for outstanding frames between two connected Fibre |
| Channel hops. |
Broadcast and Unknown | A LAN emulation component that receives all broadcast and |
Server | multicast MAC packets as well as MAC packets with an unknown |
| ATM address and transmits these messages to every member of an |
| emulated LAN. |
BUS | See Broadcast and Unknown Server. |
bus number | A bus number is assigned to every physical trunk or link that |
| connects two UltraNet Edge 3000. Routing software on the UltraNet |
| Edge 3000 uses the bus number to determine the trunks or links that |
| should be used to transfer data across the network. |
CBR | ATM Constant Bit Rate |
CRC | Abbreviation of Cyclic Redundancy Check, a common technique |
| for detecting data transmission errors. A number of file and block |
| transfer protocols use CRC in addition to checksum. |
data migration | The movement of data from one storage subsystem to another. |
