Priority queues are an essential building block for implementing advanced per-flow service disciplines at high-speed network links. In this paper, we propose novel solutions to the scalable implementation of priority queues by decomposing the problem into two parts, a succinct priority index in SRAM that can efficiently maintain a real-time sorting of priorities, coupled with a DRAM-based implementation...
Bloom filter and its variants have found widespread use in many networking applications. For these applications, minimizing storage cost is paramount as these filters often need to be implemented using scarce and costly (on-chip) SRAM. Besides supporting membership queries, Bloom filters have been generalized to support deletions and the encoding of information. Although a standard Bloom filter construction...
High-performance routers need to store temporarily a large number of packets in response to congestion. DRAM is typically used to implement the needed packet buffers, but DRAM devices are too slow to match the bandwidth requirements. To bridge the bandwidth gap, a number of hybrid SRAM/DRAM packet buffer architectures have been proposed (S. Iyer and N. Mckeown, 2002) (S. Kumar et al., 2005). These...
