-Packet Flow Ordering
-^^^^^^^^^^^^^^^^^^^^
-
-TRex Traffic Generator (TG) supports two main ways how to cover
-address space (on allowed ranges) in scale tests.
-
-In most cases only one field value (e.g. IPv4 destination address) is
-altered, in some cases two fields (e.g. IPv4 destination address and UDP
-destination port) are altered.
-
-Incremental Ordering
-~~~~~~~~~~~~~~~~~~~~
-
-This case is simpler to implement and offers greater control.
-
-When changing two fields, they can be incremented synchronously, or one
-after another. In the latter case we can specify which one is
-incremented each iteration and which is incremented by "carrying over"
-only when the other "wraps around". This way also visits all
-combinations once before the "carry" field also wraps around.
-
-It is possible to use increments other than 1.
-
-Randomized Ordering
-~~~~~~~~~~~~~~~~~~~
-
-This case chooses each field value at random (from the allowed range).
-In case of two fields, they are treated independently.
-TRex allows to set random seed to get deterministic numbers.
-We use a different seed for each field and traffic direction.
-The seed has to be a non-zero number, we use 1, 2, 3, and so on.
-
-The seeded random mode in TRex requires a "limit" value,
-which acts as a cycle length limit (after this many iterations,
-the seed resets to its initial value).
-We use the maximal allowed limit value (computed as 2^24 - 1).
-
-Randomized profiles do not avoid duplicated values,
-and do not guarantee each possible value is visited,
-so it is not very useful for stateful tests.
