Sketching algorithm provide high-fidelity approximate measurements and appears as a promising alternative to traditional approaches such as packet sampling. NitroSketch [1] is a software sketching framework that optimizes performance, provides accuracy guarantees, and supports a variety of sketches. This commit adds a new data structure called sketch into membership library. This new data structure is an efficient way to profile the traffic for heavy hitters. Also use min-heap structure to maintain the top-k flow keys.
