ESX Server shapes traffic by establishing parameters for three outbound traffic characteristics: average bandwidth, burst size, and peak bandwidth. You can set values for these characteristics through the VI Client, establishing a traffic shaping policy for each uplink adapter.

A.
Average Bandwidth

B.
Maximum Bandwidth

C.
Burst Size

D.
Peak Bandwidth

E.
Burst Average

F.
Maximum Burst

Explanation:

Traffic Shaping Policy ESX Server shapes traffic by establishing parameters for three outbound traffic characteristics: average bandwidth, burst size, and peak bandwidth. You can set values for these characteristics through the VI Client, establishing a traffic shaping policy for each uplink adapter. Average Bandwidth establishes the number of bits per second to allow across the vSwitch averaged over timethe allowed average load. Burst Size establishes the maximum number of bytes to allow in a burst. If a burst exceeds the burst size parameter, excess packets are queued for later transmission. If the queue is full, the packets are dropped. When you specify values for these two characteristics, you indicate what you expect the vSwitch to handle during normal operation. Peak Bandwidth is the maximum bandwidth the vSwitch can absorb without dropping packets. If traffic exceeds the peak bandwidth you establish, excess packets are queued for later transmission after traffic on the connection has returned to the average and there are enough spare cycles to handle the queued packets. If the queue is full, the packets are dropped. Even if you have spare bandwidth because the connection has been idle, the peak bandwidth parameter limits transmission to no more than peak until traffic returns to the allowed average load.
