Apposite's Netropy network emulators offer advanced capabilities to benchmark, troubleshoot, and optimize the performance of critical applications. Netropy's unique, high-performance Emulation Engine enables high-precision emulation of up to 15 separate WAN links to model complex network topologies or run multiple concurrent tests. Each link is configured with its own bandwidth, latency, loss and other properties. Packets can be assigned to the appropriate link by IP address range, VLAN, application port number, or any other packet identifier. Netropy models are available with up to 4 separate Emulation Engines per unit, and capacities up to 100 Gbps. Netropy is also available in a software version, NetropyVE, that runs as a virtual machine in virtual test environments. Netropy network emulators are configured and managed through an intuitive, browser-based interface for easy operation, or through a comprehensive command line interface for integration with test automation tools.
