ACCESS NETWORKS ECONOMICS ARE BREAKING Wireline Growing demand for business and residential broadband applications is straining existing access networks Service providers are struggling financially and operationally to provision, deploy, operate and manage thousands of 1GE and 10GE ports Wireless Surge in devices and media-rich applications creates relentless demand for bandwidth and quality of experience Migration to 4G/LTE creates challenging architectural and scaling issues Mobile access network (MBH) represents up to 35% of MNO capex 6 Copyright 2011 Juniper Networks, Inc. www.juniper.net
IT S TIME FOR A NEW ACCESS NETWORK Old New Multiple access networks for different applications with many touch points Capacity focused adding point to point bandwidth from access to aggregation Innovation has been limited to replacing TDM with Ethernet Macro cell backhaul Truck rolls often required for minor operational changes Inconsistent call quality (jitter, dropped calls, cell yell, etc.) Vs. Seamless end-to-end service delivery network for all applications and customers Operational intelligence and traffic steering make efficient use of existing bandwidth Flexible services applied at the access layer and optimized per customer Macro cell AND Micro cell backhaul Remote provisioning for rehoming and other configuration changes Integrated synchronization for service quality and SLA commitment 7 Copyright 2011 Juniper Networks, Inc. www.juniper.net

LAYERED HETNET SOLUTION: MACROS + SMALL CELLS IN DIFFERENT SPECTRUM Best solution is Macro and Small cell layers in separate spectrum. Macro layer Frequency f 1 True seamless mobility Large area, ubiquitous coverage High-speed mobile users Voice/Realtime services Lower spatial reuse Lower average user rate Dense Small Cell layer Frequency f 2 Nomadic data Local, non-ubiquity Nomadic/Stationary users Best effort data Micros/picos/femtos/APs Higher average user rates Separate spectrum simplifies and decouples the deployment of the two layers Layers now deploy, optimize and scale independently (for both RAN and Core) 10 Copyright 2011 Juniper Networks, Inc. www.juniper.net
COMBINED SYNCHRONOUS ETHERNET AND IEEE1588-2008 (PTP) Synchronization is a critical requirement for 3G/4G wireless networks Propagation of frequency over physical layer more accurate than over packets SyncE used to derive frequency and PTP used to drive phase SyncE and PTP traceable to common source 11 Copyright 2011 Juniper Networks, Inc. www.juniper.net

LTE SECURE NETWORKING OPTIONS LTE lacks a ciphered backhaul interface for the user plane (unlike 3G and 2G) so it may be required to secure backhaul when a 3rd party transport wholesaler is used X2 VPN S1-C VPN S1-U VPN Mobile Transport Network MME MX as Aggregation Router Backhaul Traffic Separation Use L2 or L2.5 to create VPNs that naturally separate and protect router traffic. No S1-U ciphering (enodeb backhaul). IPSec IPSec Mobile Transport Network MX as Combined SeGW and aggregation router MME S-GW Backhaul Traffic Encryption Deploy SeGW to terminate IPsec tunnels from enb. The MX provides hair-pin and traffic distribution as well IPSec IPSec SRX for mobile security termination End-to-End Mobile Security Protects subscriber user plane traffic all the way from terminal to the end-point (e.g. Enterprise) Mobile Transport Network 13 Copyright 2011 Juniper Networks, Inc. www.juniper.net
