Example text

This count is used both to provide credit-based flow-control feedback and to decide which circuits are using so much memory that their data should be discarded. The common memory architecture allows the switch to support multicast in an efficient way. A common memory allocation engine maintains a list of free locations in the shared common Figure 14 Architecture overview of CreditNet switch. Page 18 memory. Entries from this list are allocated to cells as they arrive. When a multicast cell's information is broadcast on the arrival bus, more than one port module will enqueue this cell in its list of cells to send.

This will reduce their bandwidth overhead in transmitting credit records upstream. (In fact, by adapting N2 values and by packing up to 6 credits in each transmitted credit cell, the transmission overhead for credit cells can be kept very low. ) On the other hand, an inactive VC could be given an N2 value as small as 1. With a smaller N2 value, the receiver can inform the sender about the availability of buffer space sooner, and thus increase memory utilization. The N2 value would increase only when the VC's bandwidth ramps up.

Therefore the total memory usage will never exceed (M/2 - TQ) + M/2 + TQ or M. Consequently, adaptive buffer allocation will not cause cell loss. This analysis also explains why M is divided by 2 in Equation (3). , the N2 value, to adapt to the VC's current Buf_Alloc, or equivalently, its relative bandwidth usage. That is, VCs with relatively large bandwidth usage will use large N2 values. This will reduce their bandwidth overhead in transmitting credit records upstream. (In fact, by adapting N2 values and by packing up to 6 credits in each transmitted credit cell, the transmission overhead for credit cells can be kept very low.
