purpose of network layer
Purpose of Network Layer
  • Defines functionality of network interconnection units
    • Segment to segment communication
    • Network Interconnection Unit tasks
      • Transfer of messages between segments
        • Forwarding
        • Filtering
        • Address translation
        • Re-packaging
        • Performance statistics

BAE 5030-353

network interconnection unit types
Network Interconnection Unit types
  • Repeater
    • Bit level repeating from one segment to another (physical layer)
    • Adds to effective bus length (propagation delay)
  • Bridge
    • Receives, stores and forwards messages from one segment to another (data link layer)
    • May filter messages
    • Maximum recommended transit delay is 50 ms
  • Router
    • May re-map addresses of messages from one segment to another (network layer)
    • Does not allow address claims to pass across
  • Gateway
    • Interconnects ISO 11783 protocol to different protocols (eg. Ethernet)

network port identification
Network Port Identification
  • Port Numbering
    • Each port on a network interconnection device is numbered for reference. These are standardized in Parts 1 and/or in 4 and 9
network layer message
Network Layer Message
  • Purpose
    • Acquiring NIU performance statistics
    • Setup and management of filter databases
  • Control Byte Functions
    • Filter Database Management ( 7 functions)
      • Setup filtering between port-pairs
    • Access and Reset General and Parametrics ( 3 Functions)
      • Access or reset general NIU performance data
    • Access and Reset Port-Pair Parametrics ( 3 Functions)
      • Access or reset port-pair specific NIU performance data
    • Topology query (2 functions)
      • Access Network Topology
