Product Models
Linktropy WAN Emulators
Linktropy WAN emulators simulate a single link through each pair of interfaces, offering the simplest configuration possible. If you need to emulate a single set of conditions between two networks, Linktropy is the product for you.
Linktropy Models
Linktropy Mini2: Basic, low cost emulator up to 100 Mbps in a portable form factor
Linktropy 5500: Emulates WAN links up to 1 Gbps
Linktropy 7500 PRO: Emulates four independent gigabit speed WAN links
Linktropy 10G: Emulates links up to 10 Gbps
Netropy Network Emulators
Netropy network emulators simulate up to 15 separate WAN links, each with their own bandwidth, delay, and loss characteristics, through each pair of physical ports. Packets can be assigned to individual links by IP address range (IPv4 or IPv6), VLAN ID, or MPLS label. To model complex network topologies or run multiple concurrent tests, select the Netropy network emulator.
Netropy Models
Netropy N60: Emulate complex networks up to 1 Gbps
Netropy N80: Four separate 1 Gbps Emulation Engines
Netropy 10G: Two 10 Gbps and one 1 Gbps Emulation Engines
