1.4 Relationship to Other Protocols
The following diagram shows the relationship of the Near Field Proximity: Sharing Protocol with other protocols.

Figure 2: Relationship to other protocols
The Near Field Proximity: Sharing Protocol uses the Near Field Proximity: Bidirectional Services Protocol [MS-NFPB] to establish a session between a share source and share target. That session is then used to establish a connection between the source and the target. That connection can be used by the source to send an OPC package to the target.
