Scheduling VOQ Switches under Non-Uniform Traffic

چکیده
Abstract — Input queueing is becoming increasingly important for high-bandwidth switches and routers. In previous work, we proved that it is possible to achieve 100% throughput for input-queued switches using a cell-by-cell scheduling algorithm called LQF. However, LQF is too complex to implement in hardware. In this paper we introduce a new algorithm called Longest Port First (LPF), which is designed to overcome the complexity problem of LQF and can be implemented in hardware at high speed. By giving preferential service based on queue lengths, we prove that LPF can achieve 100% throughput.

Performance of Exhaustive Matching Algorithms for Input-Queued Switches
Virtual output queue (VOQ) architecture is commonly used for avoiding head-of-line blocking in inputqueued switches. Many algorithms have been developed for transferring the cells from the VOQs to the output ports. Traditional iterative algorithms such as iSLIP and DRRM, achieve 100% throughput under uniform traffic. But under nonuniform traffic, throughput drops significantly. Recently, a new ...

High-performance input-queued switches require highspeed scheduling algorithms while maintaining good performance. Various round-robin scheduling algorithms for Virtual Output Queuing (VOQ) crossbar-based packet switch architectures have been proposed. It has been demonstrated that they can operate at high speed (e.g., OC192), and are relatively simple to implement in hardware. In particular, a...
متن کاملA Practical Scheduler For High-Speed Packet Switches and Internet Routers
The input queued (IQ) crossbar based switching, employing virtual output queueing (VOQ), is the dominant architecture for high-performance packet switches. The performance of a VOQ switch depends solely on the scheduling algorithm used. Maximum Weight Matching (MWM) algorithms have optimal performance however they are not practical due to their hardware complexity. Round Robin (RR) based algori...
