Introduction Research Goals 4G MEF HETNA Summary

Introduction Increasing number of mobile users and the evolving of wireless technologies derive the need for more bandwidth. 4G cellular networks use packet core networks for data services based on L2 (Ethernet) and L3 (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, QoS/CoS and mobility The Ethernet technology provides an attractive solution for these bandwidth and performance requirements

Research Goals Studying the existing work on the subject of mobile Ethernet-based networking (MEF, WiMAX, and LTE) Examining the compatibility of HETNA with 4G networks protocols HETNA and MEF Mobile Backhaul

Fourth Generation Cellular Communication (4G) True Mobile Broadband 1Gbps peak data rate for fixed services 100Mbps data rate for mobile services High mobility to 500Km/H Flat All-IP network architecture Based on packet switching only, unlike 3G LTE WiMAX Developed by 3GPP Built on GSM using OFDM based air interface Data Rate: 250 Mbps Supported by WiMAX Forum Based on IEEE 802.16 with OFDMA 802.16e - fixed mobility 802.16m - cellular systems Data Rate: 100Mbps – mobile 1Gbps - stationary

Carrier Ethernet Network MEF The MEF’s mission is to accelerate the worldwide adoption of Carrier-class Ethernet networks and services. MEF 22 defines Mobile Backhaul Implementation Agreement Provides generic specification for Ethernet backhaul architectures for mobile networks (2G, 3G, 4G) Key Issues: Ethernet OAM Protection and fault recovery Traffic separation (CoS) Services Synchronization Carrier Ethernet Network UNI RAN BS RAN NC

HETNA Main Components – A Scalable Ethernet Architecture for Intra- and Inter-Domain Transport Services Addressing scheme U/M L/G Address Type Sub Domain / QoS Access Interfaces - Connection-less port MAC preservation port ETNA transport port Main Components – Address Resolution System (ARS) Access Bridge (AB) Core Bridge (CB) Inter Domain Bridge (IDB)

HETNA (2) Intra Domain mobility scenario 8 – 9. Host1 keeps sending to Host2 through access bridge AB2, AB2 forwards the frames to host2 through AB3. happen until the new E-MAC of host2 arrives to host1 2-3. Host1 uses ARP to receive Host2 E-MAC address through AB1 10. The communication resumes directly between the hosts 7. The ARS sends a Redirect Notification message to AB2 6. Host2 registers itself in the ARS through AB3 4. Host1 and Host2 are communicating 5. Host2 changes location AB3 detects it 1. Host2 registers itself in the ARS through AB2 ARS (2-3) AB4 AB1 (7) (9) (1) (6) Domain Network (10) (8) (4) Host1 AB3 AB2 Host2
