52-20-07 A Survey of Congestion Control Schemes for ABR Services in ATM Networks

Broadband integrated services digital network(B-ISDN) efforts are driven by the emerging needs for high-speed communications and enabling technologies to support new integrated services. Among the available technologies, asynchronous transfer mode (ATM) has emerged as a standard for supporting B-ISDN. ATM uses short, fixed-size cells consisting of 48 bytes of payload and 5 bytes of header in order to transmit information. The fixed size allows fast processing of cells and reduces the variance of delay, making the network suitable for integrated traffic consisting of voice, video, and data. Providing the desired QOS for these various traffic types is much more complex than what is done in data networks today.
