Understanding Pluribus Network Packet Broker
The Pluribus Network Packet Broker (NPB) solution enables users to deploy a dedicated modular, scalable monitoring fabric with a distributed architecture that connects to shared analytics and security tools located anywhere in the network. A monitoring fabric deployed as part of Pluribus' NPB solution features centralized management capabilities and logically functions as a distributed virtual chassis.
A network packet broker topology is built on top of the familiar Netvisor ONE's Unified Cloud Fabric: it does not require specialized software and a custom fabric, and consequently provides a high degree of flexibility, resiliency, and operational simplicity.
Using network taps or port mirrors, the NPB service copies traffic from a production network to the ingress ports of the monitoring fabric which, in turn, redirects the copied packets to the monitoring tools (which can be located geographically apart).
Pluribus' implementation employs a VXLAN overlay to transport packets from ingress ports to a “tool farm” (that is, a group of monitoring tools) and supports Equal Cost Multi-Path (ECMP) forwarding in the underlay to address link failures.
