Aviz Service Node (ASN) is a high-performance, software-defined solution for network visibility, real-time packet processing, and metadata extraction across telecom, enterprise, data center, FTTH, campus, and edge networks. It efficiently identifies applications, extracts HTTP metadata, captures DNS information, and enables deep traffic analysis.
Designed for scalability and high availability, ASN runs on general-purpose hardware, eliminating vendor lock-in while delivering high-speed packet filtering, flow processing, and intelligent data correlation. Whether deployed in core networks or distributed environments, ASN ensures efficient traffic monitoring, security enforcement, and performance optimization at any scale.
ASN extracts essential metadata from 4G-LTE, 5G-NSA, and 5G-SA networks, offering deep visibility across all types. It specializes in correlating data using protocols like:
S11 (GTP-C), S1-U (GTP-U) for LTE/5G-NSA
N4 (PFCP), N3 (GTP-U) enhanced with N11 (SBI-HTTP2) correlations
ASN can correlate GTP-C/U for in-depth 4G/5G network analysis. It extracts detailed metadata from the control plane (N11) and user plane (N3 GTP-U), including user equipment information, traffic details, and key performance indicators.
ASN excels at managing mobile handovers in 4G and 5G networks, Maintaining seamless continuous connectivity and optimal network performance for users in motion. It can handle various handover scenarios, such as transitions between gNodeB (5G base station) and eNodeB (4G base station) or handovers involving the AMF (Access and Mobility Function) in 5G-SA networks.
ASN leverages Deep Packet Inspection (DPI) to classify over 500 applications at line rates. It extracts key network intelligence using:
Pattern recognition & SNI matching
IP geolocation & port-based analysis
User agent metadata, bandwidth usage, and performance KPIs (latency, packet loss, jitter)
By correlating IP network data from data center, edge, FTTH, and campus environments, ASN ensures end-to-end traffic intelligence, anomaly detection, and policy enforcement, making it a scalable, cost-effective solution for telecom and enterprise networks.
FlowVision also offers real-time insights:
ASN health.
Network traffic utilization.
Logs for troubleshooting.
Additionally, ASN's built-in High Availability module ensures redundancy for both small and large deployments.
