RE: Will we use tokens or not?
Dear Offer,
As far as I am concerned, the second type of "token" you mentioned
is rolled in to Ring Access method and is in the same context as Ethernet
MAC control frame (802.3x). Would I call it a token? No. But someone
could argue this to be some sort of token.
regards,
Yong.

Subject: Will we use tokens or not?
In the email discussion about RPR Vs Ethernet positioning, Yong had made
the claim that RPR does not use tokens. I would like to get a
clarification on this.
There are two types of tokens in a ring architecture. One is used as a
"ring master" which grants the permission for a node to transmit.
Clearly, RPR will not have such a token since the whole idea of spatial
reuse is that more than one node can transmit at the same time.
There is a second type of a token, a "control token" which is passed
between the ring nodes carrying all sorts of control information
(health, BW demands, and so forth). Are we saying that we won't have
such a token in RPR? If so, and being a new comer, I would appreciate
getting a pointer to any previous contribution to the group discussing
this issue (or one which documents this decision).
Thanks,
