On the other hand, the First hard work to implement TCP resulted in a very Edition that only authorized for virtual circuits. This model worked fine for file transfer and distant login applications, but many of the early work on advanced network apps, in particular packet voice during the nineteen seventies, designed apparent that occasionally packet losses shouldn't be corrected by TCP, but must be left to the applying to manage.
