Managing service-level agreements in metro ethernet networks using backpressure

Abstract

Ethernet, which has long been used for local area networks (LANs)

Quality of service modeling and analysis for carrier ethernet

“…In Chapter 3 (based on [47]), we present and analyze an Ethernet policer which provides feedback to the MEN customer network on SLA violation. The use of this mechanism results in bu¤ering at the customer side equipment which resolves the TCP performance problem by itself.…”

“…When the queue occupancy exceeds the high threshold the PauseOn message is sent and when the queue occupancy drops below the low threshold the PauseO¤ message is sent and consequently transmission is resumed. Previous works [48], [47] and [56] on Ethernet congestion control have concentrated on the throughput gain which can be achieved by using the scheme. We are not aware of any literature with an analytically tractable model of the mechanism.…”
