Design of Next Generation Access Networks
Synopsis

The overall objectives of this project are summarized below:
  1. To develop a unified theory of design for next-generation of access networks which will broaden and deepen our understanding of access networks.
  2. To design realistic and provably efficient architectures and algorithms for next generation broadband access networks and enable their incorporation into emerging technology standards.
  3. To rethink the role and design of access networks and its impact on the design of the Internet.
