....In that case, only one of them is selected. This structure is motivated by the need for concurrent and pipelined operation to keep the link and switch schedulers operating at link speeds. Several link and switch algorithms which follow this structure have been proposed by the authors [43] 44] 45][46][47] In this paper, due to space limitations, only the link and switch schedulers initially proposed in [43] will be described. These are the ones used in the evaluation results presented at the end of the paper. The authors are preparing another paper which will describe with more detail the ....

....involved in switch scheduling are applied. The port ordering phase rules the order in which output ports are examined to resolve port conflicts. This decision is captured in the ordering function. One of the ordering functions developed for the MMR is named COA (Candidate Order Arbiter) 43][46]. This function consists on selecting output ports first by level and then in increasing order of conflict within a level. Ties are broken by randomly selecting one of the ports. The rationale is that ports with the most conflicts should be matched last since those ports have the most ....
