Aviz Networks details Aviz Service Node Release 2.2 with enhanced session tracking and DPI capabilities
Aviz Networks has released Aviz Service Node (ASN) version 2.2, enhancing network observability and performance for enterprise and telecommunications environments. This update introduces new features to support seamless session continuity between 4G and 5G networks and provides improved metrics for Network Performance Monitoring (NPMO), relevant for IT and security professionals managing complex network infrastructures.
Platform Enhancements and Core Features
Autonomous System Number (ASN) 2.2 incorporates several updates aimed at improving reliability and data visibility. Notably, it offers a Control Plane handover mechanism that helps maintain continuous session tracking as subscribers transition between 4G and 5G networks without requiring network reconfiguration. The release includes new key performance indicators measuring Transmission Control Protocol (TCP) Packet Loss and jitter to deliver detailed insights into network health and user experience.
Hardware support has expanded with ASN now compatible with NVIDIA BlueField-3 Data Processing Units (DPUs) enabling Subscriber-Aware Load Balancing, and NVIDIA ConnectX Network Interface Controllers for high-throughput packet processing. These additions facilitate enhanced traffic correlation and efficient handling of large subscriber data flows in both telco and enterprise contexts.
Deep Packet Inspection Capabilities
The updated ASN features a next-generation Deep Packet Inspection engine capable of identifying over 2,700 applications and 9,000 subcategories by analyzing payload data. This granular application awareness helps network operators implement targeted policies for bandwidth management, security enforcement, and compliance monitoring.
A dynamic upgrade mechanism allows ASN’s Deep Packet Inspection (DPI) engine and protocol databases to be updated in service, avoiding any downtime and accommodating evolving application profiles and protocols promptly.
Technical Aspects of Cplane Handover and KPIs
ASN acts as an observability-driven mediation layer that passively monitors and correlates session data across different radio access technologies. By matching subscriber identifiers, it maintains a unified session view during handovers between the Evolved Packet Core and 5G Core Network (5GC), exporting real-time metadata to analytics frameworks.
Key Performance indicator (KPI) monitoring employs passive analysis of mirrored traffic to accurately quantify packet loss and jitter. These metrics are correlated with session metadata—such as IP addresses and Quality of Service (QoS) parameters—facilitating precise localization of network issues across radio access and data center segments.
Operational Implications for Network Management
The integration of improved packet processing and inspection tools in ASN 2.2 supports more comprehensive network visibility and subscriber intelligence. These functionalities enable network operations teams to manage mobility, monitor performance indicators, and perform application-level traffic analysis within a unified platform.
By supporting both telco and enterprise hardware ecosystems, ASN 2.2 offers flexible deployment options that can adapt to various infrastructure requirements and traffic profiles.
