Abstract
Today’s mobile operators face significant challenges with
handling the ever-increasing volume of mobile data traffic. With new mobile communication standards, like
4G/LTE, the mobile backhaul architecture has a clear
split of a packet-only dataplane and a management plane.
Although this new backhaul architecture yields to easier
management, we find that this architecture can be improved
further by applying the principles of Software-defined
Networking (SDN). SDN allows for better evolvability
of the dataplane without depending on a slew
of management or control protocols, allows for centralized
control of the overall infrastructure, and allows for
a richer feature set based on its programmable nature.
This paper investigates the redesign, and illustrates its
potential with mobility management as an example.
