Nevertheless, the Original effort to employ TCP resulted inside a Variation that only allowed for virtual circuits. This model worked great for file transfer and remote login apps, but some of the early work on Superior network apps, specifically packet voice in the nineteen seventies, created crystal clear that in some instances packet losses shouldn't be corrected by TCP, but ought to be left to the appliance to handle.
