Network Measurements as OGSI Service Data

Network Measurements as OGSI Service Data

• Network measurements are another form of
  meta-data
• OGSI provides standard mechanisms for accessing
  meta-data
• The ServiceData element is a wrapper around
  service specific meta-data and state
• ServiceDataValue element can contain arbitrary
  XML
• find,setserviceData portType defines standard
  mechanisms for querying and setting service data
  elements

What does this buy me?

• Allows usage of standard OGSI service tooling
• Service lifecycle, security, notification, and
  creation services
• Can use standard query engines in OGSI
  implementations
• Find by element name
• XPath, or Xquery
• Could have multiple bindings to the query
  functions
• Allows returning of SDEs in multiple encodings,
  e.g., an efficient binary format
• XMLSchema definitions of NM data will allow usage
  in OGSI, but does not preclude other uses
