On the extension of ABR flow control to legacy LANs

Managing service-level agreements in metro ethernet networks using backpressure

“…Traditionally, the backpressure mechanism is used when there is congestion on Ethernet LANs (e.g., when output queues overflow or are about to overflow pre-defined thresholds) [2,5,8,10]. However, a similar mechanism exists for asynchronous transfer mode (ATM) networks and has been extensively analyzed in the literature (see [6] and [7]). In this mechanism, when a switch detects congestion, it can set an explicit rate (per flow or aggregate flow) or congestion bit in the resource management cells, signalling its upstream neighbour or end stations to adapt to the congestion situation.…”

Quality of service modeling and analysis for carrier ethernet

“…These cells can continuously increment or decrement the tra¢ c rate of each connection in small steps. As a consequence, most of the research on congestion control for ATM builds on and optimizes the use of these RM cells ( [59], [62]). Although this mechanism can be expected to provide better performance than the Ethernet ON/OFF tra¢ c control, it is extremely complex to implement and sustain.…”
