Proposed Modification to lanswitch-06

[Kevin Dubray <[e-mail]>]

Colleagues:

Below are the modifications that Bob Mandeville is proposing to 
make to the latest LAN Switch Benchmarking Terminology draft,
<draft-ietf-bmwg-lanswitch-06.txt>.  Most, if not all, changes
are based on comments from the Munich BMWG session.

If there are no objections, Bob will incorporate the changes into
the next version of the draft, which will become the basis of a 
WG Last Call.

Modification 1

3.2.2  Bidirectional traffic

      1. The wording of defintion is slighty changed to avoid the
         repetition of DUT/SUT. The original definition:

         "Frames presented to a DUT/SUT such that each of the
         interfaces of the DUT/SUT both receive and transmit."

         now reads:

        "Frames presented to a DUT/SUT such that every receiving
         interface also transmits."

       2. Mention is now made of "forwarding rate" in addition to
         "throughput" as measurements requiring bidirectional
         traffic on full duplex devices.


Modification 2

3.3.1 Non-meshed traffic

         1. The term "non-meshed traffic" replaces the term "one-to-one
         mapped traffic" to give consistency to the three terms
         defined for traffic distribution: non-meshed, partially
         meshed and fully meshed.

         2. The term "non-meshed" is substitued throughout the document.

         3. The discussion section makes it clear that the intended
         meaning of the term is a one-to-one mapping of interfaces:

         "In the simplest instance of non-meshed traffic all frames
         are offered to a single input interface and addressed to a
         single output interface.  The one-to-one mapping of input to
         output interfaces required by non-meshed traffic can be
         extended to multiple mutually exclusive pairs of input and
         output interfaces."


Modification 3

3.3.2 Partially meshed traffic

         1. The last paragraph regarding traffic orientation will
         be stricken from the text. 

         2. The section on testing backbone connections using partially
         meshed traffic was appropriately moved up from the discussion
         section on fully meshed traffic (3.3.3) to the discussion
         section on partially meshed traffic.


Modification 4

3.3.3 Fully meshed traffic

         1. The wording of the definition is modified to make it
         consistent with the wording for the other terms dealing with
         traffic distribution.  The original definition:

         "Frames switched simultaneously between all of a designated
         number of interfaces of a DUT/SUT such that each of the
         interfaces under test will both forward frames to and receive
         frames from all of the other interfaces under test."

         now reads:

         "Frames offered to a designated number of interfaces of a
         DUT/SUT such that each one of the interfaces under test
         receives frames addressed to all of the other interfaces under
         test."


Modification 5

3.5.2 Offered Load

         1. The following statement is added:

         "Offered load MUST be indicated when reporting the results of
         forwarding rate meausurements."


Modification 6

3.6.3 Maximum forwarding rate (MFR)

         1. The label on column A of the table in the discussion section
         is corrected to read "Test Device Offered Load" in place of
         "Tets Device Offered Rate".


Modification 7

5 References

          1. Author names are added.


Modification 8

6. Acknowledgements

1. The acknowledgements section is extended.
