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
Microsoft Windows automatic detection Frame types Direct hosting Implementation considerations

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
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
Allow users to find resources Should be based on logical divisions Should use smallest possible number of
zones

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
Reduces network traffic Offers integration choices
Use gateway such as Microsoft SNA Server. Install TCP/IP on devices.

Chapter Summary
Microsoft Windows 2000 supports IPX, AppleTalk, and SNA.
Organizational requirements and constraints should be collected first for IPX AppleTalk SNA
