Information on Unconstrained Bit Rate

Unconstrained bit rate is a service class for asynchronous transfer mode networks (ATM networks) in which the cell rate may be varied arbitrarily by a source. An unconstrained bit rate service does not provide any guarantees of quality of service.

  • Available bit rate (ABR)
  • constant bit rate (CBR)
  • variable bit rate (VBR)
