Please elaborate? This makes no sense to me. Certainly, this is not the case for terrestrial communication (request/response latency is only 2× the one-way latency).
- robkop 9y agoPossibly they were thinking of first a DNS query then the actual query? That would result in two round trips.
- paragraft 9y agoBy "one way" the OP was referring to the ground-to-satellite trip taking 110ms. So by "round way trip" they meant a packet going from client to satellite to ground station (2 x 110ms). Thus 440ms.
- colanderman 9y agoOH. Of course, that makes sense. Thanks!
- brianshaler 9y agoHow long until we can co-locate application services in geosynchronous orbit to cut that latency in half?
