With exponential increase in mobile data traffic, 4G mobile core networks are grappling with unique scaling issues. The disproportionate amount of control traffic, direct exposure of core network elements to events in access network and traditional centralized architecture of mobile core networks exacerbate this problem.

We observe that today's mobile core network treats all traffic uniformly and ends up spending disproportionate amount of network resources on data flows. In Procel, we take a fresh look at mobile transport network architecture to alleviate this problem. Our approach involves classifying flows based on their requirements and the value they deliver to the user, and allocating core network resources to the flows according to this classification.  We are working on several research issues related to these areas and building a prototype system.
