Buffer and Delay Bounds in High Radix Interconnection Networks

A. Singh, W.J. Dally
2004 IEEE computer architecture letters  
We present a methodology for calculating such bounds for a practical high radix network and through extensive simulations show its effectiveness for both bursty and non-bursty injection traffic.  ...  We apply recent results in queueing theory to propose a methodology for bounding the buffer depth and packet delay in high radix interconnection networks.  ...  A statistical bound on the packet delay is essential for guaranteeing Quality of Service for delivery of packets.

A study of multistage interconnection networks operating with wormhole routing and equipped with multi-lane storage [article]

Eleftherios Stergiou
2020 arXiv   pre-print
The rationale behind this innovative scheme is to introduce a more efficient network technology, thus providing a better quality of service (i.e. streaming media vs. file transfer).  ...  Associating the lane storage with each physical channel for movement of the flits allows for high levels of packet flow and makes the system more robust.  ...  This work In order to provide high quality of service (QoS) for today's high-speed networks, a new MIN is proposed that uses the wormhole routing method.  ...
