Enhanced Subscriber Intelligence: The load balancing feature significantly enhances the ASN node's capability in enabling subscriber-level intelligence. It achieves this by egressing correlated control and user plane traffic to probes for in-depth analysis.

Efficient Load Distribution: This feature ensures efficient distribution of network load across multiple tools. By balancing the traffic, it prevents any single tool from becoming overwhelmed, thereby maintaining optimal network performance.

Comprehensive Network Analysis: The load balancing feature is crucial for achieving comprehensive network analysis. By directing correlated traffic to specific probes, it allows for detailed monitoring and assessment of traffic pattern.

Currently, wo subscriber-aware load balancing options are available, which can be configured based on customer requirements:

1. Subscriber aware load balancing based on IMSI

In the high-stakes world of telco networks, operators must manage massive subscriber traffic while ensuring optimal performance, metadata extraction, and application identification. Subscriber traffic, split into control packets (e.g., GTP-C, PFCP, N11) and user packets (GTP-U), is often processed separately in the core network, complicating analysis. Without precise correlation, directing both traffic types to the same tool for comprehensive insights is inefficient and prone to errors.

Introducing Subscriber-Aware Load Balancing (SALB) in the Aviz Service Node (ASN), running standalone on the NVIDIA BlueField-3 (BF3) DPU. This solution harnesses P4 programmable datapath and embedded ARM cores to deliver peak datapath performance, ensuring correlated traffic reaches the right tools with unmatched efficiency. Now generally available, ASN SALB on BF3 DPU empowers operators to achieve high-speed, intelligent traffic processing for next-generation telco networks.

In both Telco and IP network domains, maintaining consistent application performance depends heavily on understanding packet delivery reliability and latency behavior across dynamic network segments. Whether in a 5G Core, Data Center (DC), or FTTH aggregation network, Aviz Service Node delivers precise KPI measurements for TCP Packet Loss and TCP–UDP Jitter — enabling end-to-end insight into real user experience. These metrics are critical for engineers troubleshooting throughput degradation, latency spikes, or congestion-related impairments that traditional flow counters often fail to expose.

Aviz Service Node computes TCP Packet Loss by passively analyzing mirrored traffic flows at the packet level. It tracks TCP sequence numbers, retransmissions, and acknowledgment gaps to accurately determine the volume and rate of lost packets. The analysis is performed per flow and correlated with user session metadata such as IP addresses, VLANs, QoS tags, and tunnel identifiers (e.g., GTP in Telco or VXLAN/GRE in IP networks). This cross-domain correlation allows engineers to pinpoint where in the path — between RAN and Core, or between leaf-spine nodes in a DC fabric — the loss originates. Similarly, TCP–UDP Jitter is computed by evaluating inter-packet timestamp variations, providing real-time insight into delay fluctuations for both connection-oriented (TCP) and connectionless (UDP) traffic streams.

Packet deduplication is a feature used to identify and eliminate duplicate network packets, improving network efficiency and reducing redundant data processing. It works by comparing incoming packets.

As mobile operators continue to transition between 4G and 5G, one of the biggest operational challenges is maintaining consistent Control Plane visibility when subscribers move across Radio Access Technologies (RATs). The Aviz Service Node bridges this visibility gap. Acting as a passive, observability-driven mediation layer, it maintains continuous and correlated session tracking across EPC and 5GC interfaces — enabling seamless 4G ↔ 5G handover insights without any change to the live network configuration.

Aviz Service Node automatically detects handovers between EPC and 5GC through IMSI-based session matching and performs an in-place session upgrade logic — maintaining a unified view of the subscriber session throughout the transition. During each transition, ASN dynamically updates metadata exports to Kafka, reflecting real-time field updates such as RAT type, user type, IP, and TEIDs — ensuring analytics and monitoring systems always have synchronized, current session data.

User Information

Introduction

ASN DPI (Deep Packet Inspection) identifies applications using pattern-based signatures. Aviz Networks provides seamless signature updates, allowing support for new applications or enhancements of existing ones without impacting the existing deployment.

The list below specifies the unique unified data type of metadata attributes exported from ASN, 5GC-control-session-data-mapping, EPC-control-session-data-mapping, and the user-session-data-mapping file.

Application, Protocol, and Category Identification with DPI

ASN Deep Packet Inspection enables precise identification of 2,700+ applications and 9,000+ subcategory applications, and their attributes by analyzing network traffic in detail. This capability allows organizations to know exactly which apps are running—whether it’s video, audio, gaming, file transfer, or chat—along with the underlying protocols they use. Categorizing traffic helps in applying tailored policies for security, bandwidth allocation, and compliance. By understanding both the app and its category, enterprises and telcos can optimize network performance, enforce acceptable use policies, and gain valuable insights into user behavior and traffic trends

Modern networks—whether telco cores, enterprise data centers, or edge sites—demand flexible, high-performance packet intelligence to keep pace with AI-driven workloads and subscriber traffic. Aviz Service Nodes (ASN) deliver a software-defined solution for advanced traffic analytics, application identification, and AI-powered insights on commodity servers.

In our latest release, we’re thrilled to announce support for NVIDIA ConnectX NICs, building on our existing x86 platform compatibility. With ConnectX, ASN leverages cutting-edge NVIDIA technology to achieve unparalleled throughput, low latency, and future-proof scalability. From 4G/5G traffic correlation to real-time flow tracing, ASN on ConnectX empowers operators to modernize network observability effortlessly.
