Yes, I’m familiar with that write up…. I wrote it!


And yes, it's why I later grabbed a bunch of compression algorithms and went with lzss as it compressed well, fast an ld was tiny compared to others...


I would highly recommend compressing the frames for sure.  On high latency links it sure helps too. 


It's also why cisco had licensed LZS compression for their serial links.  And totally worth looking at.

Interestingly - has a good writeup on the Doom IPX issue - it was a poor implementation sending mainly empty frames. shows how adding compression to a bridge is able to eliminate 80% of the traffic.


Bring this back on topic, perhaps adding optional LZO compression, but enabled by default, would be a good idea for RetroNet.

But if you want to use RetroNet to play Doom across IPX with buddies across town, then you should be able to do so.

Err - maybe not.

I recall doing that once or twice on our office LAN at the time, it was very chatty - as I recall it sucked most of the available b/w.

(Or maybe that was just 'cause it was using broadcast packets)
