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.
