The 13th IFIP/IEEE Symposium on Integrated Network and Service Management (IM 2013) will be held 27-31 May 2013 at Ghent University, Belgium. Held in odd-numbered years since 1989, IM 2013 follows the 25 years tradition of NOMS and IM as the primary IEEE Communications Society's forum for technical exchange on management of information and communication technology focusing on research, development, integration, standards, service provisioning, and user communities. IM 2013 will focus on the theme "Smart Management in a Virtualized World" presenting recent, emerging approaches and technical solutions for dealing with future cloud, network and ICT infrastructures, as well as with novel services provided on top of these infrastructures. IM 2013 will offer five types of sessions: technical, application, poster, panel and dissertation digest. High quality will be assured through a well qualified Technical Program Committee and stringent peer review of paper submissions. A special call for demonstrations is organized to allow industry partners and researchers to demonstrate early products and prototypes.
