8 DGT NetProbe 20x 10Gb/s ingress ports, 20x 10Gb/s egress ports Data filtering, based on IP addresses, port numbers, VLAN, type of protocol etc. Data aggregation, distribution and pre-processing, including defragmentation, de-duplication and packet-slicing. 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

13 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 s High volume of data of UP requires distributed processing. Smart TAP device provides also load balancing based on IP address allocated to subscriber 13

14 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 s. PDP Session Session IP Flow Records IP Flow Source/Destination IP address Source/Destination port numer Protocol type HTTP Transaction Records DNS Transaction Records Other (tbd) Service Records 14

15 User Plane analysis? Web Web HTTP HTTP MMS Data Services Pipe MMS

16 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

17 CP & UP Separation 17

18 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

19 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
