Cubro's Packetmaster is a Network Packet Broker (NPB) designed to eliminate network traffic blind spots, optimize and filter traffic, load balance, and support high-speed connections up to 400Gbps. It provides capabilities for aggregation, replication, and filtering of network traffic to monitoring systems and security tools. Packetmaster receives and aggregates network traffic from switch SPAN ports or network TAPs, which can then be filtered, deduplicated, and optimized for efficient use of security and performance tools. It supports filtering up to OSI Layer 4 and can handle various protocols including VLAN, MPLS, GRE, and DNS traffic.
