Routing Table Maintenance Protocol
The Routing Table Maintenance Protocol , or RTMP for short , is a network protocol for AppleTalk . RTMP updates the routing tables in short intervals of 10 seconds in an AppleTalk computer network . It works according to the distance vector algorithm and is derived from the Routing Information Protocol (RIP).
It is defined in RFC 1742 .
In addition, a routing entry in the local router has one of three statuses, "Good", "Suspicious" and "Bad". An entry that has not been updated for a certain time passes through the latter two states before the entry is ultimately deleted from the routing table.
The protocol belongs to the transport layer .
The AppleTalk protocol stack
The AppleTalk protocols can be divided into several layers that form a protocol stack . The protocols can be classified in the ISO-OSI reference model as follows :
| OSI layer | AppleTalk protocol stack | ||||||
| 7th | AFP | PAP | |||||
| 6th | |||||||
| 5 | ZIP | ASP | ADSP | ||||
| 4th | ATP | AEP | NBP | RTMP | |||
| 3 | DDP | ||||||
| 2 | LLAP | ELAP | TLAP | FDDI | ← AARP | ||
| 1 | LocalTalk |
Ethernet driver |
Token Ring Driver |
FDDI driver |
