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

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.

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

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
