 Introduction Research Goals 4 G MEF HETNA Summary Introduction Research Goals 4 G MEF HETNA Summary

INTRODUCTION Increasing number of mobile users and the evolving of wireless technologies derive the INTRODUCTION Increasing number of mobile users and the evolving of wireless technologies derive the need for more bandwidth. 4 G cellular networks use packet core networks for data services based on L 2 (Ethernet) and L 3 (IP) Carrier Ethernet (standardized by the MEF) is evolving towards being used as access for Mobile Backhaul Recent developments of scalable Ethernet-based network architectures, support traffic engineering, Qo. S/Co. S and mobility The Ethernet technology provides an attractive solution for these bandwidth and performance requirements
