Source Behavior for ATM ABR Traffic Management: An Explanation
The Available Bit Rate (ABR) service has been developed to support data
applications over Asynchronous Transfer Mode (ATM) networks. The network
continuously monitors its traffic and provides feedback to the source end
systems. This paper explains the rules that the sources have to follow to
achieve a fair and efficient allocation of network resources.Comment: IEEE Communications Magazine, November 1, 1996, vol 34, no11, pp50-5
The OSU Scheme for Congestion Avoidance in ATM Networks: Lessons Learnt and Extensions
The OSU scheme is a rate-based congestion avoidance scheme for ATM networks
using explicit rate indication. This work was one of the first attempts to
define explicit rate switch mechanisms and the Resource Management (RM) cell
format in Asynchronous Transfer Mode (ATM) networks. The key features of the
scheme include explicit rate feedback, congestion avoidance, fair operation
while maintaining high utilization, use of input rate as a congestion metric,
O(1) complexity. This paper presents an overview of the scheme, presents those
features of the scheme that have now become common features of other switch
algorithms and discusses three extensions of the scheme
Performance and Buffering Requirements of Internet Protocols over ATM ABR and UBR Services
The Asynchronous Transfer Mode (ATM) networks are quickly being adopted as
backbones over various parts of the Internet. This paper analyzes the
performance of TCP/IP protocols over ATM network's Available Bit Rate (ABR) and
Unspecified Bit Rate (UBR) services. It is shown that ABR pushes congestion to
the edges of the ATM network while UBR leaves it inside the ATM portion.Comment: IEEE Communications Magazine, Vol 36, no 6, pp152-15
