I personally >think that geographical domains make a great deal of sense. It seems to me that geographical domains would be an awful lot easier to implement and maintain. The uucp network is not well known for keeping maps up to date and routing tables up to date or just about anything up to date. A Geographical domain system would be less susceptible to falling apart if some places decide to wait a year or two to update their tables since the mail would be able to get reasonable close before it fails. With a non-geographical system suppose machine a connected to site b in maine moves to california and gets new connections downlink from a machine that hasnt updated its tables lately. Since he has the same address his mail gets to machine c who has no idea where to look for the address and it bounces. with a geographical system the mail would at least get to maine or even closer before it gets lost and there is a greater chance that a nearby machine would know who its for. I know I'm rambling here but basically what I'm trying to say is that a geographical system means a file will get reasonably close to its destination before the specific machine has to be known. This would not hold true for internal organizational networks such as .dec since it has its own internal routing. -- "I feel fine..." ...{utzoo, decvax, ihnp4, cbosgd, utcsri, mnetor}!utcs!scott scott%utcs.toronto.edu@csnet-relay.arpa scott@utoronto.bitnet scott@utcs.utoronto.bitnet Disclaimer: The above is not actually the opinion of anyone at all but especially not the administration or staff of this institution.
