This book addresses challengesand potential solutions surrounding the dramatic yearly increases in bandwidthdemand. The editors discuss the predicament surrounding current growth, whichis predicted to continue because of the proliferation of disruptive, highbandwidth applications like video and cloud applications. They also discussthat in addition to growth, traffic will become much more dynamic, both in timeand direction. The contributors show how large changes in traffic magnitudeduring a 24-hour period can be observed, as day-time business users have verydifferent demands to evening-time residential customers, and how this playsinto addressing future challenges. In addition, they discuss potentialsolutions for the issues surrounding situations where multiple content andcloud service providers offer competing services, causing the traffic directionto become more dynamic. The contributors discuss that although the WDMtransponder technology can be upgraded to 100Gb/s in the short to medium term, andto 1Tb/s in the longer term, bandwidth-variable transponders that can adjusttheir bandwidth quickly and under software control are needed. In addition,they posit that by using a flexible grid the optical spectrum can be used in amore flexible way. The book comprehensively addresses all these topics and aimsat providing a reference for the coming years for researchers, engineers, andpractitioners working in the field. Planning and algorithms for elastic opticalnetworks (EONs) are presented, including mathematical models and algorithms.

• Discusses the evolution from WDM to flexible and the new applications that EONs can support

• Shows how in the data plane, transmission in EON will cover the next generation of bandwidth variable transponders, novel modulation formats, mitigation of impairments, and node architectures

• Presents extensions to GMPLs and OpenFlow for EONS in the control plane, extensions to GMPLS and OpenFlow for EONs, and the concept of in-operation planning
