- Of course if cisco would watch what folks like Gandalf are doing this
- would be less of a problem. They have LAT specific compression that
- crunches 22 bytes of LAT header into 12 bits, and then heavily
- compresses everything else.
-
- Sure it is a bridge only (for now) and has only 2 56kb WAN ports with
- one Ethernet port, but is so inexpensive and so desirable with that
- compression that it may be better for a hub site cisco box to NOT use a
- wan port to some remote site IGS, but to come out a cisco ethernet port
- that only goes to a Gandalf compressing bridge that goes 56kb to a
- remote Gandalf. Much better performance, and less $s.
-
- The Gandalfs are commodity priced and marketed through major mational PC
- distributors and have a street price that makes this a very attractive
- configuration with a pair of them cost way less than a remote cisco IGS.
- Flash for upgrades, too!
-
- Now if cisco would deign to add comprtession even if only for low link
- speeds...
