Presentation Transcript
chapter 3 multiprotocol network design
Chapter 3: Multiprotocol Network Design
  • Designs That Include Multiple Protocols
  • IPX Design Concepts
  • AppleTalk Design Concepts
  • SNA Design Concepts
multiprotocol design requirements and constraints
Multiprotocol Design Requirements and Constraints
  • Internetwork Packet Exchange (IPX) networks
  • AppleTalk networks
  • Systems Network Architecture (SNA) networks
design considerations
Design Considerations
  • IPX
    • IPX network number addressing
    • IPX frame types
    • Methods for securing data
  • AppleTalk
    • Network numbers or network number addressing range
    • Zones
  • SNA
    • Mainframe connectivity requirements
    • Network segments, routers, Media Access Control (MAC)– layer bridges, or source routing bridges
determining ipx frame types
Determining IPX Frame Types
  • Microsoft Windows automatic detection
  • Frame types
  • Direct hosting
  • Implementation considerations
connecting ipx
Connecting IPX
  • Integrate IPX into IP networks with Point-to-Point Tunneling Protocol (PPTP) or Layer 2 Tunneling Protocol (L2TP).
  • Protect IPX data by using virtual private network (VPN).
  • Use Microsoft Proxy Server 2.0 for IPX to IP gateway.
appletalk addressing
AppleTalk Addressing
  • Similar to IP addressing
  • Network number
  • Node ID
  • Considerations
    • Base network number range on expected number of nodes.
    • Allow for network expansion.
    • Assign unique network numbers.
appletalk zones
AppleTalk Zones
  • Allow users to find resources
  • Should be based on logical divisions
  • Should use smallest possible number of zones
sna networks
SNA Networks
  • Data Link Control (DLC) is the most common SNA protocol.
  • DLC uses source routing bridges or MAC-layer bridges.
  • Using SNA gateways reduces the number of network segments that require DLC.
sna and tcp ip integration
SNA and TCP/IP Integration
  • Reduces network traffic
  • Offers integration choices
    • Use gateway such as Microsoft SNA Server.
    • Install TCP/IP on devices.
chapter summary
Chapter Summary
  • Microsoft Windows 2000 supports IPX, AppleTalk, and SNA.
  • Organizational requirements and constraints should be collected first for
    • IPX
    • AppleTalk
    • SNA
