Aviz Service Node R2.3 expands session-level telemetry with deeper subscriber exports, enhanced Deep Packet Inspection (DPI) payload extraction, configurable multi-NIC support and non-disruptive Deep Packet Inspection (DPI) upgrades, offering operators unified control- and user-plane visibility for 4G, 5G‑NSA and enterprise environments.

Research Overview

Release 2.3 extends the node's ability to capture and export session and subscriber data across control and user planes, with new DPI capabilities and flexible deployment options. The changes apply to cellular environments including 4G and 5G‑NSA as well as to enterprise IP networks.

Key Findings

R2.3 introduces user-focused active bearer session exports for 5G‑NSA, unique identifiers for exported streams to aid end-to-end traceability, and extraction of DSCP values from inner and outer IP headers. The release also brings direct inclusion of RADIUS attributes in control-session records, capture of PRIO Cause for deletion events, and extraction of rulebase attributes from RADIUS payloads.

Technical Breakdown

Subscriber telemetry

Active bearer session exports provide per-subscriber context for ongoing dedicated bearers, enabling session lifecycle visibility and improved alignment between control and user plane records. Exports can carry a configurable identifier, supporting integration with Kafka-based analytics and consistent tracing across sessions.

Protocol and DPI

The release adds Session Initiation Protocol (SIP) and Real-time Transport Protocol (RTP) extraction and correlation, including Call-ID linkage and SDP-negotiated media parameters for voice and multimedia flows. The DPI engine supports targeted payload extraction and dynamic signature updates, with updates applied in service to avoid interruption.

Operational Impact

Boot-time configuration through the management plane permits in-service provisioning and reduces the need for redeployment when applying new settings. Deduplication controls and options to skip metadata exports let operators tune bandwidth and processing use, and an available dedup-only boot mode focuses resources on duplicate suppression where required.

Product Update

Hardware support now covers mixed Intel and Mellanox ConnectX NICs with independent mapping of control and user planes to optimize throughput and redundancy. The product also supports non-disruptive updates to DPI engines and signature databases via the management interface to maintain continuous metadata coverage.

Overall, R2.3 broadens session intelligence and protocol-aware extraction while adding deployment and upgrade flexibility for telco and enterprise monitoring use cases. This Blog Signals brief is a fact-based summary of the vendor blog.
