ABSTRACT

ABSTRACT: Abstract—Internet traffic is growing rapidly, driven by  new applications such as the Internet of things (IoT). To  overcome router scaling limitations, router bypass has  been introduced. Traditional bypass is based on provisioning  fixed-size bypass channels, which was shown to under-  utilize link capacity. In software defined networking (SDN),  router bypass can be requested as a service by the application layer.

 This study explores the opportunity to bypass  routers efficiently without the link underutilization of  the traditional bypass.We combine SDN and dynamic layer  provisioning to implement dynamic router bypassing and  show how this leads to improved efficiency. A simulation  built to compare the traditional bypass with the SDN-based  bypass showed that SDN-based bypassing enhanced efficiency  by 33%. When bypass traffic is increased, we show  that the output capacity of a node increases up to 56%, limited  by optical capacity rather than router capacity.
