Hello,
I think this question may have been asked before, but what is the minimum latency and delay I can expect from a satellite connection? What kind of delay have others seen in a working situation? What factors should be considered in end to end connectivity architecture when utilizing a satellite link?
Any help appreciated,
Geosynchronous orbit is about 36,000 km from the center of the earth. Round-trip to the satellite is ~72,000 km; the speed of light is 300,000 km/sec. That works out to 240 milliseconds at the minimum for one-way packet delivery. --Steve Bellovin, http://www.research.att.com/~smb Full text of "Firewalls" book now at http://www.wilyhacker.com
