VIAVI TestCenter : How to configure specific burst packet in VIAVI TestCenter?
Requirement: Configure 100Mbps packets with frame size 64 bytes in a 1G port. Require to send 10ms with uniform speed then stop for 10ms then send it again in the same way.
Step:
1. Calculate packet per second: 1,000,000,000bps / (96+8*8+64*8) * 0.1= 148,809.524 packets/s
2. Calculate bursts value per second: 1s/(10ms+10ms)=50 bursts/s
3. Calculate burst size: 148,809.524 / 50 = 2,976.19 packets/burst
4. Calculate bits per burst: 10ms*(1,000,000,000 bits/s)=10,000,000 bits
5. Calculate IFG: 2,976.19*(IFG+8*8+64*8)=10,000,000, so IFG=2,784bits=348 bytes
In the VIAVI TestCenter, set burst size to 2,976, IFG to 348 byte, load to 10%, then you will get this specific burst packet as requirement.
