<p>Methods and apparatus are set forth for utilizing the restricted token operation on an FDDI network. Two service primitives are defined to facilitate the control of restricted dialog. The first defines what class of token can be captured for the purpose of transmitting asynchronous data. Secondly, a primitive is defined for use at the end of each transmit request to give control over the token type that will be issued at the end of a given transmission. A hardware protocol is defined which provides reliable control over these two parameters, together with methodology for linking frames in a buffer memory during restricted operation. The combination of the hardware protocol and methodology allows restricted dialog to be realized without real-time software interaction.</p> |
