Scalable Alternatives to Virtual Output Queuing
—To avoid head of line blocking in switches, Virtual Output Queues (VOQs) are commonly used. However, the number of VOQs grows quadratically with the number of ports, making this...

Comparison of Two Output Models for the BMAP/MAP/1 Departure Process
—The departure process of a BMAP/MAP/1 queue can be approximated in different ways: as a Markovian arrival process (MAP) or as a matrix-exponential process (MEP). Both approximat...

Cache-oblivious shortest paths in graphs using buffer heap
We present the Buffer Heap (BH), a cache-oblivious priority queue that supports Delete-Min, Delete, and Decrease-Key operations in O( 1 B log2 N B ) amortized block transfers fro...
