GTP Correlation for Mobile Carriers Feature Brief

Correlate Subscriber Traffic for Better Visibility

GTP Correlation helps mobile operators correlate GTP control and user plane traffic at the subscriber level. The feature brief explains how Gigamon Deep Observability Pipeline and FlowVUE can filter, sample, load balance, and forward subscriber sessions to monitoring, analytics, and billing tools across LTE and 3G networks.

Key Topics Covered:

• Subscriber-aware GTP traffic visibility
• GTP Subscriber Filtering and Load Balancing
• FlowVUE subscriber-aware traffic sampling
• Subscriber monitoring, performance and QoE

Technical Highlights:

• Correlates GTP-c and GTP-u messages by subscriber ID and tunnel ID
• Filters on IMSI, IMEI, MSISDN, GTP version, and mobile core interface
• Supports LTE and 3G networks with GTPv1 and GTPv2
• Load balances GTP sessions across up to 16 tool ports using IMSI
• Can forward 100 percent of traffic for a sampled subscriber subset
• Supports up to 2 million high-value subscribers in a GTP forward list
• Uses APN and QCI attributes for FlowVUE and GTP forward-list criteria
