18 WAN Emulation Bandwidth control 1 Kbps up to 10 Gbps Latency/Delay 0 milliseconds up to 1.5 seconds per stream (for 1Gbps link) 0 milliseconds up to 0.5 seconds per stream (for 10 Gbps link) Single delay, Uniform, Random distributions Packet Loss Rate % Packet Reordering Rate % with Delay range of up to 2 seconds Packet Duplication Rate % Logic Error insertion Rate - 10^-1 to 10^-9 Maximum Frame Size Supported 2048 bytes 18

19 WAN Emulation Parameter Configurations Packet impairment model includes automated and manual mode: Automated: Periodic and Random Packet impairment options. Note: Single and Burst packet loss supported Manual impairment: This allows user to manually impair either a single packet or burst of packets at run time. 19

20 PacketLoss For a Packet Loss rate of 1%, 1 packet out of 100 packets are dropped i.e. for every 100 packets received, 100th packet will be dropped consistently. Random Packet Loss" option, user can randomize the packets selected for dropping. Though packets are selected randomly for dropping, the configured rate is still maintained. 20

21 PacketLoss Burst Packet Loss, to drop a burst of packets at a time varies randomly between the min and max burst size Manual Packet Loss" option, instantaneous packet drop, the configured rate is still maintained. 21

22 Packet Reordering During Packet Reordering, the selected packet will be held for the time/packet offset configured in the Delay offset parameters and then reintroduced into the output traffic for transmission. 22

23 Packet Reordering Time Delay Offset Time Delay offset, can range between 0 and up to 2 seconds (2000 msec). Each reordered frame is delayed for a random amount of time, falling between the specified minimum and maximum values. Packet Delay Offset For Packet offset delay, the reordered frame will be held until runtime selected offset frames are received, before being reinserted into the stream. 23
