The average-case complexity of counting distinct elements
We continue the study of approximating the number of distinct elements in a data stream of length n to within a (1? ) factor. It is known that if the stream may consist of arbitra...

Streaming Algorithms with One-Sided Estimation
Abstract. We study the space complexity of randomized streaming algorithms that provide one-sided approximation guarantees; e.g., the algorithm always returns an overestimate of th...

A Buffer Space Optimal Solution for Re-establishing the Packet Order in a MPSoC Network Processor
We consider a multi-processor system-on-chip destined for streaming applications. An application is composed of one input and one output queue and in-between, several levels of ide...

Sampling time-based sliding windows in bounded space
Random sampling is an appealing approach to build synopses of large data streams because random samples can be used for a broad spectrum of analytical tasks. Users are often inter...

Byzantine disk paxos: optimal resilience with byzantine shared memory
We present Byzantine Disk Paxos, an asynchronous shared-memory consensus algorithm that uses a collection of n > 3t disks, t of which may fail by becoming non-responsive or arb...
