The AX.25 Link Access Protocol for Amateur Packet Radio is a data link layer protocol derived from the ITU-T X.25 data link pro- tocol with modifications for use by amateur radio operators. One of the authors has produced a prototype AX.25 connected mode DTN Convergence Layer (CL) based on the existing DTN2 reference im- plementation. Initial testing of this implementation was undertaken on Linux in order to compare the performance of the implementa- tion with the performance of native AX.25 links. Initial results ap- pear to indicate that the current prototype can be up to 25 percent more efficient than using the Linux TCP/IP over AX.25 implemen- tation in certain circumstances. The experimental results also re- veal situations where obvious improvements can still be made to the implementation.
