WT2200S Impairment Emulator

• With 1G/10G port bidirectional impairment emulation function.

• It has a wide range of impairment functions and can accurately emulate impairment at linear velocity stream.

• Jitter latency can be realized by generating a latency for all packets or for specific packets according to specific conditions.

• It can cause impairment such as discarding, duplication, reorder, and modification to all packets or specific packets according to specific conditions.

• Packets with specific content can be inserted at a specific rate, and ultra-long frames, ultra-short frames, and FCS error frames can be constructed and inserted.

• The available bandwidth can be limited according to the specific ratio to support bandwidth jitter.

• BER Simulation can be generated at a specific ratio.

Single device provides 2 link of 1G RJ45 + 2 link of 1G SFP

• Impairments can be set independently for each channel of the link and can be started and stop pedseparately or concurrently.

• Support to filter FCS error frames on the line

Impairment With Packet Filters

·Template: src/dst MAC, frame type, src/dst IP, UDP src/dst port number, TCP src/dst port number, VLAN ID, VLAN priority (QinQ supported), MPLS label, MPLS TC

·User-defined: Specify the location and content of the byte to be matched

·Range matching: Packet Loss can match specified bytes in a range of values

Channel-based Impairment Statistics

Number of error bits, packet number of latency, loss, duplication, misorder, background traffic, modification

Channel-based Traffic Statistics

·Number of rx packets, number of tx packets, rx rate (fps, bps, %), tx rate (fps, bps,%), number of received FCS error packets

·Channel-based graphical statistics of packet rate
