available bit rate; ABR
Technical term in computer networking; refers to a service category in ATM networks where the bit rate can vary based on available bandwidth.
In ATM networks, the available bit rate changes according to traffic conditions.
Fixed bit rate (CBR) provides a constant bandwidth, while ABR adjusts dynamically.
Variable bit rate (VBR) also varies, but ABR specifically uses feedback to avoid congestion.
Compound of 利用可能 (available) and ビットレート (bit rate), a direct translation of the English computing term.
