Ethernet is meant for short distances and very low loss rates. While it (and GRE) will work across oceans given the modern Internet, performance may not be optimal. That's especially true with bridged Ethernet if you have lots of stations on the bridge. DDCMP is specifically for long distance point to point links, and works better than Ethernet if there is a non-trivial packet loss rate. I tend to pick DDCMP fairly often even though these points were a lot more valid 40 years ago than they are today. paul _______________________________________________ HECnet mailing list -- hecnet(a)lists.dfupdate.se To unsubscribe send an email to hecnet-leave(a)lists.dfupdate.se
