Motivation

• Applications need to find network resources
• Distributed network management
• Overlay node detection
• Required nodes need not to be strictly on data
  path
• NW management searches for nodes neighbours
• Overlay nodes searching some function close to a
  path (where is a relay?)
• Separation of communication pattern and
  functionality

3
GISTs MRM

• GIST is already locating nodes in the network
  with a particular property
• i.e., finding some network resource
• GIST already provides two communication patterns
• Path-coupled MRM
• Loose-end MRM
• MRM is modular
• Other types of MRM can be added

4
Additional Patterns

• Echo pattern
• locate nodes close to the application's node
• Starts at a single point (node)
• Distributing in rings from the center
• Uses a configurable diameter
• Path-directed pattern
• Locate specific nodes close to data path between
  two nodes
• Follow data path
• Expands search to the side of the path
• Use a sideways expansion parameter

5
Goals Non-Goals

• Non-goals
• Immediate integration into GIST
• Senseless patterns (e.g. Xmas tree)
• Goals
• Identifying further interest (people, use cases,
  and applications)
• Definition of new MRM (as extension to GIST)
