AMP Controller Handles

AMP Controllers have two types of handles: Physical Link Handles and Logical Link Handles.For data, command and event operations between the Host and an AMP Controller, a Logical Link Handle is used where a Connection Handle is specified, unless a Physical Link Handle is explicitly specified. A Physical Link is an association between the local Controller and a remote Controller. For any AMP Controller, there can be at most one Physical Link. The Host is responsible for allocating Physical Link Handles. A value of 0 shall not be used for a Physical Link Handle. Physical Links are created and removed explicitly, and encryption keys are established on a per Physical Link basis. The AMP may support one or more Physical Links (representing different remote devices) at any one time.

 

For each PhysicalLink, an AMP Controller provides zero or more Logical Links.

 

A Logical Link is an allocation of bandwidth or other resources for application level data transfer between the local AMP Controller and a remote AMP Controller. A Logical Link exists with respect to a specific Physical Link and the Controller ensures this Handle's uniqueness. The AMP shall support one or more Logical Links(representing distinct resource allocations) over any one Physical Link.
