The 19th IEEE LANMAN Workshop continues the LANMAN tradition as a leading forum for showcasing the latest technological advances in local and metropolitan networking. LANMAN 2013 will be held on April 10-12, 2013 at the Etterbeek campus of the Vrije Universiteit Brussel in Brussels, Belgium. The LANMAN workshop seeks both theoretical and experimental contributions. Single-track presentations are planned to stimulate technical exchange among researchers and practitioners with a broad interest in networking. We expect the workshop to be a forum for discussion of new and interdisciplinary ideas on new architectures, paradigms, concepts, and economic and service models; novel and speculative ideas are particularly encouraged. We also encourage studies based on measurements from real-life networks and testbeds.
