Message from the Technical Program Committee Chairs

摘要

Welcome to the 2011 ACM SIGCOMM Conference in Toronto, Canada. It has been our pleasure to oversee the tremendous efforts volunteered by our technical program committee and other individuals in shaping this year's technical program. We hope that you will find the papers selected for the technical program stimulating and thought-provoking, and that you enjoy the conference!rnSIGCOMM 2011 received 223 submissions, and we accepted 32 papers, for an acceptance ratio of 14%. This represents a modest drop over the number of submissions from previous years. We received submissions from authors in at least 36 countries, and the final program reflects the significant geographical diversity across submissions, with authors representing 12 different countries and 44 distinct institutions.
