A not insignificant +portion of this use turns out to be random prodding and poking of one system +by another. An example of this is the "Survey" mechanism that many sites are +constructing to see "who's up." Several systems have noted that this one +mechanism alone accounts for a log of their overhead, and is not chargeable to +any given user. + +In response to this particular problem, MIT-DMCG and UCLA-NMC, who have both +been doing surveys for some time, have agreed upon a standard format for host +survey data and will make it available to the network community. They will be +joined by a third site, and will provide a standard socket to obtain this +information. The data will be a concise character stream so as to be both +human and machine readable. + +The exact format of the data and the socket number will be forthcoming. + +The intent of all this is for all other sites to stop surveying on their own +and get this data from one of the participating "Official Surveyors" either +prompted by a user's request or on a periodic basis, whatever they wish. + +This should, itself, help considerably to eliminate a lot of the network +'noise factor.' But, in addition, we should all try to be more aware of the +cost of this type of traffic and try to avoid repeated interactions with a +given Host without some expressed consent - be it an account number of some +specific experiment. + + + + + + + + + + + + + + + +BB/ph -- cgit v1.2.3
