Aviz Networks Details OPB and ASN for Outage Visibility

Aviz Networks describes an end-to-end observability stack and illustrates it with a managed-service outage case, mapping raw packets to flow context and telemetry even during link recovery. For enterprise IT and security teams, the update centers on packet visibility, 5G protocol parsing, and operator queries.

Research Overview

The article reviews an outage scenario involving a managed service provider after a mid-market infrastructure upgrade left telemetry incomplete and root-cause analysis unclear. It then summarizes a partner perspective on open deployment choices and follows with a component-level description of Aviz’s observability stack and related use cases.

The stack is presented as a workflow connecting packet handling, deep inspection, and operator assistance through a unified interface. The article also states that the solution supports hardware-agnostic operation and SONiC-ready deployments.

Key Findings

In the outage example, the team used Aviz elements including Open Packet Broker (OPB) and Aviz Service Nodes (ASN) to narrow down false leads and identify the failure. The article says lightweight agents embedded in switches kept collecting telemetry during the outage.

When links returned, historical data streamed in to provide the “X-ray view” needed to troubleshoot. The article includes a CTO quote from Integrated IT describing a shift toward transparency and proactive engagement.

Technical Breakdown

The article describes three integrated components: OPB, ASN, and Network Copilot (NCP), coordinated through Flow Vision as a single UI. OPB is described as a white-box traffic management fabric that can filter, replicate, aggregate, slice, label, and tunnel traffic.

For protocol handling, OPB is described as supporting granular L2–L4 filtering and 5G GTP header parsing, plus symmetric load balancing. The ASN portion is described as x86 software appliances for deep packet inspection, metadata extraction, KPI generation, application identification, and deduplication across telco and enterprise environments.

NCP is described as an on-prem AI-powered assistant built on open-source LLMs, using “verified” telemetry with RAG to answer natural-language queries while aiming to reduce hallucinations. The article also describes end-to-end correlation from Cisco ACI and 5G sources via OPB and service nodes, plus real-time deduplication before exporting data to downstream tools.

Operational Impact

The article presents use cases across telco observability, application visibility, and data-center deduplication. It states that the telco workflow includes GTP-C/U correlation at scale, per-user/session KPIs, and 5G SA/NSA analytics.

For application visibility, it describes dashboards covering bandwidth, OS/device profiling, geo data, and threat detection. For deduplication, it states that 90%+ traffic reduction from TAPs occurred before tools, with the goal of preserving compute and reducing false positives.

Under natural-language queries, the article includes an example question about which apps are most used by 5G users, with traceable answers via NCP. It also describes Flow Vision as covering traffic flows, rules, tunnels, and health spanning OPB and ASN nodes.

Product Update

The article states OPB is hardware-agnostic and “SONiC-ready,” listing Broadcom (Trident, Tomahawk) and NVIDIA Spectrum (1/2/3) as supported targets. It says 400G is in production and that 800G+ is in active qualification.

In the partner section, a field CTO from Source Code is quoted describing alignment with open and flexible choices for hardware, NOS, and deployment model. The article also frames OPB and NCP as tied to openness, observability depth, and neutrality, while ASN provides inspection and deduplication functions.

The article’s overall takeaway is that Aviz Networks positions its packet-to-flow pipeline—OPB, ASN, Network Copilot, and Flow Vision—as a way to maintain visibility during service disruption and support operator workflows afterward. For enterprise IT and security decision-makers, the focus remains on packet parsing, flow correlation, deduplication, and natural-language queries within an observability stack.
