Phasing-out of Legacy Network Protocols - IPX and AppleTalk


What are IPX and AppleTalk?

IPX and AppleTalk are two old legacy network protocols. IPX is from Novell which interconnects networks using Novell's NetWare clients and servers, whereas AppleTalk is a suite of network protocols developed by Apple for Macintosh computers.


Why are we phasing them out?

As the TCP/IP protocol has become the global standard for networking, the use of IPX and AppleTalk on the campus network has declined significantly in recent years. Both Novell and Apple have recommended users to migrate their Netware clients / servers and Macintosh machines to TCP/IP protocol. Apple had also terminated its support for AppleTalk back in 2009. 

Phasing out these legacy protocols will decrease our support costs, and increase our flexibility in selecting networking infrastructure equipment in future. In fact, it is rather difficult now to source a router which supports these two legacy protocols.


When will they be phased-out? What is the impact?

Starting from February 2015, Novell IPX and AppleTalk will no longer be routed on the PolyU campus network. Netware and Macintosh clients and servers still using IPX or AppleTalk can no longer be accessed through the PolyU backbone network infrastructure if they are not on the same local area network (LAN). However, they can still access each other if they are connected to the same LAN. Users are therefore recommended to migrate these machines to TCP/IP protocol instead.

If you have any enquiries or need assistance in migrating / upgrading your systems, please contact the ITS Help Centre at 2766 5900.
