....multimedia flows within the InfiniBand framework [16] 17] As it will be detailed in Section II, the problem of providing architectural QoS support within switching elements in cluster and local area environments remains practically unsolved. Thus, the MultiMedia Router (MMR) architecture [18][19][20] arises as a solution to provide hardwarebased QoS support within an interconnection element targeted for use in cluster and LAN environments. Also, conventional best effort traffic must be seamlessly integrated in the proposed solution, and link bandwidth utilization should be maximized. ....
....operation, since in this case the extraction of information from the candidate vectors cannot be made while the scheduling algorithm is processing the candidates from the previous level. A more detailed discussion of the hardware requirements for both COA and CCA algorithms can be found in [19]. In that work, a block level hardware implementation of the COA and CCA algorithms is carried out, and chances for a parallel and pipelined implementation are identified, in order to estimate the feasibility of a hardware implementation of these algorithms. Estimations show that only 2 or 3 ....

....therefore, large buffers are required to minimize data losses; and 2) ATM switches for WANs usually support thousands of connections concurrently. The only known compact implementation of ATM in a LAN environment is ATLAS I [15] The main goal pursued by the MultiMedia Router (MMR) project [16][17] is to design compact single chip routers able to support a large number of multimedia connections while allocating the remaining bandwidth to best effort traffic. The MMR should handle this hybrid traffic efficiently, satisfying the QoS requirements of multimedia traffic, minimizing the average ....
....point. For the tests carried out in this section, the round size was configured with K = 16, and buffer size was set to 1 flit per buffer. Due to space limitations, only results for CBR traffic are included. The conclusions obtained for VBR traffic were qualitatively the same, and can be found in [17]. Two flit sizes were considered: 128 bits and 1024 bits. As phit size is fixed to 16 bits, the respective flit cycles are equal to 9 and 65 router clock cycles, considering also the transmission of the control word associated to every flit (see Section III D) This control word is transmitted ....
