Cisco Nexus Dashboard Data Broker (NDDB) (formerly Nexus Data Broker (NDB)) with Cisco Nexus Family switches is a software-defined, programmable solution for packet brokering. Packet brokering is the aggregation of network traffic mirrored or copied using network/optical TAPs or Cisco Switched Port Analyzer (SPAN) for monitoring and visibility. In contrast to monitoring solutions based on traditional packet brokers, the Cisco NDDB packet brokering approach offers a simple, scalable, and cost-effective solution well suited for customers who need to monitor higher volume and business-critical traffic for security, compliance, and application-performance measurement. It also enables real-time traffic visibility with an event-based approach through northbound APIs.
Network Packet Brokers (NPBs) are the middleman that guarantees that monitoring and security appliances have a comprehensive view of network traffic and that those tools are operating at peak efficiency. Cubro NPBs incorporate features like traffic aggregation, traffic replication, filtering, load-balancing, header-modification and more. More advanced network packet brokers also support Deep packet inspection (DPI) which is an advanced monitoring technique and a useful application for telcos.
We monitor all Network Packet Broker (NPB) reviews to prevent fraudulent reviews and keep review quality high. We do not post reviews by company employees or direct competitors. We validate each review for authenticity via cross-reference with LinkedIn, and personal follow-up with the reviewer when necessary.
