Switch fabric design for high performance IP routers: A survey
2005, Journal of Systems ArchitectureCitation Excerpt :However, buffered Banyan/Delta networks are very sensitive to non-uniform traffics, especially hot spot, regardless of the buffering strategy, due to a phenomenon called “tree-saturation effect” which can severely degrade the performance of all traffic within a MIN [61,70,121] under hot-spot traffic patterns. Example solutions to improve throughput performance in hot-spot situations are: (1) extra stages of switching elements to provide alternate paths [138]; (2) networks using combining techniques or with combining switches [44,102,120,134]; (3) use of multiple parallel networks [57]; and (4) use of flow-control techniques to avoid congestion [27,47,113]. Items 1 and 3 are self-explanatory.
Switch fabric architecture analysis for a scalable bi-directionally reconfigurable IP router
2004, Journal of Systems ArchitectureCitation Excerpt :Numerous solutions to improve throughput performance in hot-spot are available. Examples are (1) extra stages of switch elements to provide alternate paths [50]; (2) networks using combining techniques or with combining switches [15,41,49]; (3) use of multiple parallel networks [18]; and (4) use of flow-control techniques to avoid congestion [10,16,38]. However, major drawbacks are the need for intense HW logic making it extremely expensive, and for the cases of combining networks and of use of flow-control based techniques, out-of-order packet delivery could result [56].
