چکیده

Existing sketches often have low memory efficiencies when performing per-flow measurement tasks on skewed IP streams. In this paper, we propose Diamond Sketch, a novel sketch that dynamically assigns an appropriate number of atom sketches to each flow on demand, improving the accuracy considerably while keeping a comparable speed.

Accurate Per-Flow Measurement with Bloom Sketch

Sketch is a probabilistic data structure, and is widely used for per-flow measurement in network. The most common sketches are the CM sketch and its several variants. However, given a limited memory size, these sketches always significantly overestimate some flows, exhibiting poor accuracy. To address this issue, we proposed a novel sketch named the Bloom sketch, combining the sketch with the B...

Processing Data-Stream Join Aggregates Using Skimmed Sketches

There is a growing interest in on-line algorithms for analyzing and querying data streams, that examine each stream element only once and have at their disposal, only a limited amount of memory. Providing (perhaps approximate) answers to aggregate queries over such streams is a crucial requirement for many application environments; examples include large IP network installations where performan...

Detecting Hidden Anomalies Using Sketch for High-speed Network Data Stream Monitoring

Monitoring network data streams in real-time to check security event become more and more important along with the rapid growth of Internet applications. The detection typically treats the traffic as a collection of flows that need to be examined for significant changes in traffic pattern (e.g., volume, number of connections). However, as link speeds and the number of flows increase, keeping pe...

Reverse Hashing for Sketch-based Change Detection on High-speed Networks

With the ever-increasing link speeds and traffic volumes of the Internet, monitoring and analyzing network traffic usage becomes a challenging but essential service for network administrators of large ISPs or institutions. There are two popular primitives for efficient analysis over massive data streams: heavy hitter detection and heavy change detection. Although numerous approaches have been p...

Surfing Wavelets on Streams: One-Pass Summaries for Approximate Aggregate Queries

We present techniques for computing small space representations of massive data streams. These are inspired by traditional wavelet-based approximations that consist of specific linear projections of the underlying data. We present general “sketch” based methods for capturing various linear projections of the data and use them to provide pointwise and rangesum estimation of data streams. These m...
