The Apposite 10G4 Network WAN Emulator is the perfect solution for testing the performance of network applications in real-world conditions. With 8 SFP+ Ethernet ports, it provides up to 10Gbps of throughput and can support up to 80 Gbps of aggregate traffic. The 10G4 also offers 4 emulation engines at 10 Gbps and a maximum packet rate of 119 million pps. It can classify packets based on IP source and destination address range (IPv4 or IPv6), VLAN, TCP or UDP port number, IP ToS, MAC address, MPLS label, or any other packet contents. Bandwidth can be adjusted from 100 bps to 100 Gbps in 1 bps increments, while delay can be adjusted from 0 ms to 10,000 ms or greater in each direction in 0.01 ms increments with constant, uniform, or normal distributions. The 10G4 also offers random, burst, periodic, BER, Gilbert-Elliott, or recorded loss and data corruption, as well as network outage simulation. Finally, background utilization can be adjusted from 0 to 100% in increments of 0.1%, and the 10G4 supports PCAP replay, RED or tail drop queue management, priority or round robin queuing.
