|
* Service Access Point (SAP)
|
|
*
|
|
* A SAP specifies the definition of an interface used between two adjacent
|
|
* layers. The SAP is named for the services the lower layer provides to
|
|
* the upper layer.
|
|
*
|
|
* The types of SAPs used are:
|
|
* Stack - defines the interfaces between stack service entities.
|
|
* These are further divided into:
|
|
*
|
|
* Stack class SAP - which identifies the type of interface
|
|
* used. All SAPs of a particular class will provide
|
|
* the same interface services to the higher layer.
|
|
* All stack command codes are constructed using class
|
|
* SAP values.
|
|
*
|
|
* Stack instance SAP - which identifies the specific identity
|
|
* of the layer providing the class interface.
