We propose and experimentally demonstrate a control-plane framework to realize online spectrum defragmentation (DF) in software-defined elastic optical networks. Experimental results show that the spectrum DF enabled by OpenFlow reduces the blocking probability effectively. 1. Introduction It is well known that by using a flexible grid, elastic optical(More)
Over the past decade, the fast development of the Internet has pushed the scales of end users, network devices and applications to grow exponentially. That made the Internet architecture become more and more complicated, which impedes the introduction of new protocols and slows down the support of new services. In response to these issues, software-defined(More)
