PPT-SDN Scalability Issues

Last Class Measuring with SDN What are measurement tasks What are sketches What is the minimal building blocks for implementing arbitrary sketches How do we tradeoff between accuracy and space. jarschelinformatikuniwuerzburgde University of Wurzburg Chair of Communication Networks Wurzburg Germany 1 Introduction In todays Internet services are very di64256erent in their requirements on the underlying transport network In the future this div Asad M.
