The ERICA switch algorithm for ABR traffic management in ATM networks

Abstract: We propose an explicit rate indication scheme for congestion avoidance in ATM networks. In this scheme, the network switches monitor their load on each link, determining a load factor, the available capacity, and the number of currently active virtual channels. This information is used to advise the sources about the rates at which they should transmit. The algorithm is designed to achieve e ciency, fairness, controlled queueing delays, and fast transient response. The algorithm is also robust to measurement e… Show more

“…Unlike the ECN extension, the network feedback in the X-BDS model not only notifies the edge routers about congestion but also carries additional information such as the arrival rate and aggregate RBR on the congested link. A similar idea is used in ATM networks for Available Bit Rate (ABR) congestion control [24] where the feedback carried by the resource management cells also includes rate information. However, the ABR congestion control relies on per-flow information stored in the network core and tries to achieve utilization goals first and only then seeks fairness.…”

“…In what follows, we refer to our main policy simply as Policy (13) for convenience. Next, let us briefly explain the ERICA algorithm [16]. ERICA computes the available bandwidth ABR according to ABR Target utilization (Link Capacity (VBR CBR) ).…”

“…These schemes were found to substantially improve system performance and offer more flexibility to switch designers. Several explicit-rate feedback schemes have been proposed in recent years; amongst these are Enhanced PRCA (EPRCA) [22], the Dynamic Max Rate Control Algorithm (DMRCA) [10], and the well-known Explicit Rate Indication for Congestion Avoidance (ERICA) [16]. We shall consider the last algorithm above in detail for comparison purposes with our algorithm.…”
