Introduction to the OFC 2014 special issue

We are glad to provide our readers a special issue of the best networking papers from OFC 2014. The initial selection process involved the Editors-in-Chief of JOCN and the OFC Program Chairs. We invited the best contributed systems/networking papers of the conference to submit to this invitation-only special issue. This special issue is extensive and includes 59 papers ??? almost double the number of papers published in last year's special issue. The main topics covered are elastic networks, software-defined networks, and passive optical networks.
