Data Model

Service Data Encoding

Service Data Transport

• Service Definition (Subset of W3C XML-Schema 1.0)

Alternative Encoding: • XML Document • XDR based binary encoding • Others (e.g. RADIUS, Diameter AVP)

Alternative Transport: • File based exchange (of XML or XDR) • Streaming (XDR only) • Others (e.g. RADIUS UDP, Diameter TCP/SCTP)
