class PE_MISORDER

Bases: object

Configures the misordering depth in number of packets.

Note

probability * (depth + 1) should be less than 1,000,000. (see PED_FIXED)

get()

Get the misordering depth in number of packets of a flow.

Returns:

the misordering depth (Range 1 - 32). Default value.

Return type:

PE_MISORDER.GetDataAttr

set(depth)
