Hi!

Topic: ATM inverse multiplexing (IMA)

I am currentely reading the ATM IMA specification (V1.1,
AF-PHY-0086.001), and I have a very basic question to which I did not
find the answer in the above document:
In which order does the round-robin send / fetch the cells?

Everywhere in the document, it looks to be by increasing link order (the

link ID are sent in ICP cells by the transmitter so they are also known
at reception side), but I did not find this behaviour written anywhere.
The best I found is propably in Appendix B (top of pasge 154) where it
says:
"...and the cells are read out of the buffers in the assigned link
multiplexing order..."
Does this mean "by increasing link ID number?

If you ever know any other place on the web where IMA is dicussed, I'd
enjoy
to know: A general view of how the different finate state machine
interract to each other would be welcome (the Group FSM, the link TX FSM

the link RX FSM, and the IMA synchro FSM...)


Thank-you for taking the time to read this.

Enjoy your day!
