Cubro's Sessionmaster is a network packet broker that provides advanced traffic management capabilities for network monitoring and security applications. It offers functionalities such as filtering up to OSI Layer 4 and beyond, allowing for precise traffic control and analysis. Sessionmaster is designed to handle complex network environments and can process various types of network traffic, including IPv4, IPv6, and encapsulated protocols like VXLAN, GRE, and GTP. It performs GTP load balancing in hardware, correlating session messages and enabling handling of multiple 100 Gbit traffic with a single unit. The Sessionmaster load balances and filters traffic at full line rate, enhancing monitoring tool efficiency. It supports GTP inner IP range filtering and load balancing in hardware at full line rate, allowing for selective user plane monitoring in LTE networks.
