2 UHP SATELLITE BACKHAUL SOLUTION Capabilities Sftware-defined netwrk (SDN) Supprt fr different standards Seamless glbal cverage High-speed cnnectivity Flexible tplgy and wavefrms Efficient use f satellite bandwidth Easy t deply, reliable equipment Advantages Reduce backhaul csts Increase revenue and prfitability Imprve netwrk perfrmance Launch new services Penetrate t new regins Easy future enhancements Backup fr terrestrial backhaul 56

3 WHY USE UHP FOR CELLULAR BACKHAUL? One-fr-all technlgy: Sftware-Definable Functinality Mst scalable platfrm: start with single SCPC link and SW migrate t a TDM/TDMA netwrk DVB-S2X bandwidth-efficient mdulatin and cding Highest TDMA efficiency: 96% and fast BW allcatin Highest transmit capability : 450 Mbps aggregate Extremely high prcessing capability up t 190K PPS Rbust L2 interface can carry Metr Ethernet traffic, as well as Layer 3 IPV4 / IPV6-ready NMS with XML-based API fr easy integratin with OSS/BSS r centralized NMS Sphisticated QS with VLAN management and built-in 2G, 3G & LTE backhaul ptimizatin Best netwrk availability: Ge-Redundant Teleprts with Fast switchver and dual-band netwrks Field prven with majr Mbile Netwrk Operatrs in the USA 57

8 Web Interface & SNMP 3G & LTE GTP DECODING AND ENCODING 3G & LTE prtcl encapsulates user data in GTP GTP must decded first t allw ptimizatin and acceleratin 3G/LTE (e)ndeb SAT Link The platfrm is cmpsed f three layers: Ethernet Bridge Bridge Interface - Filters and captures all IP/UDP/GTP and SCTP traffic. Traffic nt matching the filter cntinues acrss the bridge GTP 3G/LTE Tunnel Tracking GTP - 3G/LTE Tunnel Tracking - Prcesses the signaling messages and manages the GTP tunnels between the base statin and the cre netwrk Applicatins Optimizatin, Byte Caching, TCP Acceleratin & Offlad are the applicatins that prcess the traffic received frm the GTP layer Optimizatin Applicatins TCP Acceleratin Offlad 62

9 OPTIMIZATION 2G, 3G & LTE BACKHAUL RAN Optimizatin slutin prcesses mbile traffic using a multi-stage ptimizatin algrithm designed specifically fr mbile netwrks Optimizatin OPEX Results: Vice Optimizatin: Savings typically 40% t 50% Data Optimizatin (Hub t Remte): Savings typically 15% t 35% Data Optimizatin (Remte t Hub): Savings typically 25% t 45% Queue Mapping Packet Aggregatin Header Cmpressin Packet Cmpressin Three queues, these are High, Medium, and Lw Each f the queues is cnfigured individually with parameters including the aggregatin perid and the maximum packet size Cmbine multiple small packets int a single large packet befre sending the traffic t the WAN link Packet Aggregatin save up t 50% f the bandwidth Mbile netwrk aware versin f Header Cmpressin treats the uplad and dwnlad backhaul paths independently, supprting multiple IP rute QS netwrk architectures Prprietary lssless cmpressin algrithms, specifically designed fr mbile signaling and data packet service, are applied t all utging WAN traffic 63

14 WHAT OUR CUSTOMERS SAY ABOUT UHP? Packets per secnd f HUB and remte with LTE Optimizer We HIT the system with and the system was able t handle it withut a single packet lst, there is n satellite mdem n the marked that supprt that lad Fast start up UHP rebts and cme back nline in ~12 secnds s despite the Base statin discnnect and recnnect the calls are nt drp ( just 12 secnds f silence) Rbustness f QS Having a 45Mbps OC and 5Mbps IC; We tested QS with 7 Pririty Levels where HUB was laded with 400Mbps f Level 1 traffic (bth sides) and system was able t prcess and transmit higher Queues withut prblems Lw Jitter With Current TDMA frame cnfiguratin, the system was suppsed t have a max jitter f 15ms. Hwever, when the Lad tests were in prgress Jitter never went ver 2~5ms Quick reslutin f issues Certain issues were faced during thrugh LTE apprval tests (in sme extent it was expected); ther vendrs tk weeks t fix similar prblems and UHP fixed it in a matter f hurs 68
