What is the full form of AURP?

The Full form of AURP is “AppleTalk Update-based Routing Protocol”. AppleTalk tunnelling permits a corporation chairman to associate a minimum of two local internets through an unfamiliar organization framework to shape a huge wide region organization (WAN).


An AppleTalk WAN may comprise of a minimum of two local AppleTalk internets associated through a tunnel supporting a TCP/IP web. In such an AppleTalk WAN, local internets use AppleTalk protocols, while the unfamiliar organization framework utilizes an alternate protocol family. A tunnel is often either an unfamiliar organization framework or a highlight point interface.

There are two kinds of tunnels, double endpoint tunnels and different endpoint tunnels.

AURP carries out multipoint tunnelling by providing components for information exemplification and therefore the proliferation of steering data to explicit switches.

Given below is the diagram of AURP Architecture Model −

AppleTalk uses an address-resolution method like TCP/IP's ARP (Address Resolution Protocol). The AppleTalk version is called AARP. The primary network layer routing protocol in AppleTalk is the Datagram Delivery Protocol (DDP) which provides a besteffort delivery which is a Connectionless Datagram service like UDP.

There are five key implementations exist at the transport layer of the AppleTalk protocol suite −

  • Routing Table Maintenance Protocol (RTMP)

  • Name Binding Protocol (NBP)

  • AppleTalk Update-Based Routing Protocol (AURP)

  • AppleTalk Transaction Protocol (ATP)

  • AppleTalk Echo Protocol (AEP)


The advantages of AURP are as follows −

  • Apple includes AppleTalk automatically in the Macintosh operating system (OS).

  • The configuration and implementation is very easy.

  • Setting up a small workgroup in AppleTalk is simple and inexpensive.


The disadvantages of AURP are as follows −

  • It is not suitable for very big networks.

  • It is slow as compared with other LAN links.

  • It is unsuitable for bandwidth-intensive applications.
