8.6.10.1 ExecutePSFPOperation
The ExecutePSFPOperation
procedure is responsible for fetching the next gate operation from the OperControlList, along with any parameters associated with it, and performing actions based upon the gate operation that has been fetched. The value of the PSFPListPointer variable (8.6.10.3) is used as an index into OperControlList. The procedure processes the operation according to its operation name (Table 8-7) as follows:
a) If the operation name is SetGateAndIPV, then the StreamGateState parameter value associated with the operation is assigned to the PSFPOperGateStates variable (8.6.10.5), the IPV parameter value is assigned to the OperIPV variable (8.6.10.7), and the TimeInterval parameter value associated with the operation is assigned to the TimeInterval variable (8.6.9.4.24). If the TimeInterval parameter value associated with the operation was 0, the TimeInterval variable is assigned the value 1. If there is an IntervalOctetMax parameter associated with the gate operation, then that parameter value is used to set the value of the IntervalOctetsLeft variable (8.6.10.8); otherwise, the IntervalOctetsLeft variable is set to a value greater than the maximum possible number of octets that the gate could pass during TimeInterval.
b) If the operation name is unrecognized, then the PSFPListPointer variable (8.6.9.4.15) is assigned the value of the OperControlListLength variable (8.6.9.4.23) and the TimeInterval variable (8.6.9.4.24) is assigned the value 0.
c) If there is no TimeInterval parameter associated with the operation, then the TimeInterval variable is assigned the value 0. 8.6.10.2 SetPSFPGateStates This procedure sets the stream gate state as specified by the value of the PSFPOperGateStates variable (8.6.9.4.22). 8.6.10.3 PSFPListPointer An integer used as a pointer to entries in the OperControlList (8.6.9.4.19), each entry consisting of a stream gate control operation with its associated parameters (Table 8-7). A value of zero points at the first entry in the list; a value of (OperControlListLength) – 1 points at the last entry.
8.6.10.4 PSFPAdminGateStates The initial state of the gate associated with the stream gate is set by the List Execute state machine (8.6.9.2) and is determined by the value of the PSFPAdminGateStates variable. The default value of PSFPAdminGateStates is open. The value of PSFPAdminGateStates can be changed by management. 8.6.10.5 PSFPOperGateStates The current state of the gate associated with the stream gate. PSFPOperGateStates is set by the List Execute state machine (8.6.9.2), and its initial value is determined by the value of the PSFPAdminGateStates variable (8.6.10.4).
8.6.10.6 AdminIPV The initial value of the OperIPV variable (8.6.10.7) associated with the stream gate is determined by the value of the AdminIPV variable. The default value of AdminIPV variable is the null value. The value of the AdminIPV variable can be changed by management.IEEE 802.1Qci pdf download.
