requests was exceeded.
PEERREQ The service peer requested the
operation to be aborted.
NETERR An underlying network error

Service primitive sample
The behavior of service primitives is illustrated using a time sequence chart

This figure depicts a simple non-confirmed service. The client invokes an
S-request primitive, which results in an S-indication primitive in the server (WSP
