Application-specific data analysis Optional, extendable in 5GB/s steps DPI+ functionality covering full packet inspection and modification available for up to 120Gbps of processed data in real time (covering ca. 60% of total switching capacity). 2U, rack-mounted DGT NetProbe Architecture Management module Blade server Blade server Blade server Blade server Blade server Blade server Blade server Blade server Blade server Data Bus Switching processor Data Bus Data Bus Blade server DGT NetProbe in NetScan Moitoring System Management module Blade server Blade server Blade server Blade server Blade server Blade server Blade server Blade server Blade server Data Bus Switching processor Data Bus Data Bus Blade server DGT NetProbe Data processing Management module Blade server Blade server Blade server Blade server Blade server Blade server Blade server Blade server Blade server Data Bus Switching processor Data Bus Data Bus Blade server DGT NetProbe Data processing Management module Blade server Blade server Blade server Blade server Blade server Blade server Data Bus Switching processor Data Bus Data Bus Blade server Blade server Blade server Blade server Control Plane Frames User Plane Frames User Plane Records DGT NetProbe functions CP & UP data separates on Gn interface DPI (Deep Packet Inspection) feature available in DGT NetProbe allows to separate CP and UP messages based on GTP message type UP smart distribution over farm of local servers High volume of data of UP requires distributed processing. Smart TAP device provides also load balancing based on IP address allocated to subscriber 13 DGT NetProbe functions UP pre-processing User Plane data are processed directly at DGT NetProbe. IP flow – based records are peridically generated and forwarded into local processing servers. PDP Session Session IP Flow Records HTTP Transaction Records IP Flow • Source/Destination IP address • Source/Destination port numer • Protocol type DNS Transaction Records Other (tbd) Service Records 14 User Plane analysis ? HTTP HTTP Data Services Pipe Web Web Email MMS Email MMS User Plane analysis Service is determined by: • Port Number • pattern (DPI, Deep Packet Inspection) • Domain Service-based analysis • What services are consuming the pipe? • Who is consuming the pipe? • What devices accessing the pipe? Service can be measured by • Bytes Up, Bytes Down, Total Volume • Throughput • Latency CP & UP Separation 17 Integration with NetScan CEM system NetScan already supports easy-to-use, WEB- based Graphical User Interface for O&M users. Existing GUI will be updated to visualise EPC- & LTE-specific data. Completely new GUI will be developed for CC (Customer Care) users in a close cooperation with those users: • Only subscriber-related, serviceoriented information available. • Integrated with other CC systems, with similar look & feel. • Available already with deployment Phase 2 Drill- down for packet session analysis Intuitive search engine helps to find questioned PDN sesion Brief information, including PS QoS parameters available already at the list of found PDN sessions level Deep analysis of selected PDN session at the level of control plane and user plane NetScan Customer Service Experience Data Collection & pre-procesing Overview Local Server Database IMSI Local Server CEIs Local Server CEIs CEIs Cell Collection and Aggregation Subscriber threads PDU’s Processing BTS BSC Gb PDN SGSN Iu-PS Node B RNC Gn GGSN Customer Experience Indicators (CEI’s) Customer Quality Indicators (CQIs) •CSI •CDI •etc… 2G/3G Voice CEIs 2G/3G SMS CEIs 2G/3G Data Mobility CEIs 2G/3G Data Service CEIs Voice Services Data Mobility Data Services •MOCallSuccess •MTCallSuccess •MOCallAttempt •MTCallAttempt •MOCallRABAttempt •MOCallRABAvgDuration •MTCallRABAttempt •MTCallRABAvgDuration •etc… •AttachAttempt •AttachAvgDuration •AttachSuccess •DetachAttempt •DetachSuccess •PDPActAttempt •PDPActFail •PDPActSuccess •etc… •HTTPGetAttempt •HTTPGetSuccess •HTTPGetBytes •HTTPGetAvgClientSetupTime •HTTPGetAvgServerSetupTime •HTTPGetAvgDownloadTime •HTTPGetAvgEndtoEndTime •HTTPGetAvgTTFB •etc… Data aggregation and presentation Handset / Device Cell / Network Application Server Service Customer Sales and Account Manegement Aggregation Server Aggregation Server Service & Product Manegement Error event Local CSI CSI Server Local CSI CSI Server Local CSI CSI Server Local CSI CSI Server Network Engineering and Operations QoE, KPI distribution By Subscribers By Applications QoE By Devices By Locations 24 Event Correlation Customer Pre/Post Paid, Corporates, HVA … Experience Impact Failure Service Performance Voice, Data, SMS… Cause Device Performance Phones, Smartphones, Tablets… Network Performance RAN 2G/3G/4G, Core, 25 NetScan Roadmap Roadmap Disclaimer The information provided in this document is subject to change without notice and does not carry any contractual obligation.
