RATE Control for Bandwidth Allocated Services in IEEE 802.3 Ethernet
نویسندگان
چکیده
We investigate how to add rate control to full-duplex IEEE 802.3 Ethernet. We envision the need for rate control in order to enable bandwidth allocation in future Ethernet in the First Mile (EFM) subscriber services. We propose a RATE mechanism that can be implemented with a simple byte-based leaky bucket. We demonstrate with simulation methods that RATE can isolate flows and provide lower loss and delay than no control or PAUSE control for misbehaving flows. We also show, using simulation models, that RATE and PAUSE can complement each other where a switch is RATE controlled and the sending source PAUSE controlled. An appendix gives a formal specification of RATE.

The standard IEEE 8 0 2 . 3 ~ is introduced to manage XONXOFF flow control mechanism in full duplex gigabit Ethernet. In a IEEE 802 .3~ network, a downstream station can send XOFF messages to upstream stations to stop them from sending data until a specified time slot has passed or the downstream station receives a XON message. The development of efficient XONXOFF flow control mechanism is stil...

Latency is a critical parameter in Ethernet networks developed for Factory Automation applications. Latency is not a defined value for Ethernet as specified by the IEEE 802.3 standard. Nor is Ethernet inherently synchronous or repeatable. This disconnect between the inherent characteristics of Ethernet and the needs of Factory Automation applications must be bridged though careful architecture ...
