* This SBA code implements the Synchronous Bandwidth Allocation |

|
* Agreement" dated December 1th, 1993. |
|
* ******************************************************************* |
|
* |
|
* PURPOSE: The purpose of this function is to control |
|
* synchronous allocations on a single FDDI segment. |
|
* Allocations are limited to the primary FDDI ring. |
|
* The SBM provides recovery mechanisms to recover |
|
* unused bandwidth also resolves T_Neg and |
|
* reconfiguration changes. Many of the SBM state |
|
* machine inputs are sourced by the underlying |
|
* FDDI sub-system supporting the SBA application. |
