Internet Protocol Encapsulation of AX.25

Status of this

This memo describes a method for the encapsulation of AX.25 (
Amateur Packet-Radio Link-Layer Protocol) frames within IP packets
This technique is an Experimental Protocol for the
community. Discussion and suggestions for improvement are requested
Please refer to the current edition of the "IAB Official
Standards" for the standardization state and status of this protocol
Distribution of this memo is unlimited

The AX.25 Amateur Packet-Radio Link-Layer

The AX.25 Amateur Packet-Radio Link-Layer Protocol is described
the publication by that name [1], incorporated here by reference

Each AX.25 packet ("frame") is encapsulated in one IP datagram
Normally no AX.25 frame will exceed 330 octets, so fragmentation
the IP layer should not be necessary. However, experiments
larger AX.25 frame sizes may require the use of standard
fragmentation and reassembly procedures

When an AX.25 frame is encapsulated within an IP packet, HDLC
elements (flags and zero-stuffing) are omitted, as the IP
adequately delimits the beginning and end of each AX.25 frame.
16-bit CRC-CCITT frame check sequence (normally generated by the
transmission hardware) is included. In all other respects, AX.25
frames are encapsulated unaltered

Each such IP datagram shall have a protocol number of 93.

if you see any problems within the linking, don't worry be happy,
this is version 0.1 of the Relevance System and you gotta expect some crappy subroutines sometimes,
just be content we did not write this in Java, which would have made this "bigger and better" HAHAHHA.
