Description

The Advanced Gateway Server, or AGS, is an early Cisco router that moved data between networks with different protocols. Its software came from router code that William Yeager started to write at Stanford University in 1980.

Importance

In 1985 Len Bosack, who managed computers for the Stanford computer science department, asked Yeager for the router code. Cisco, incorporated in December 1984, used the code, and Stanford later licensed the software to the company. The Stanford routers ran on a 68000 board from Andy Bechtolsheim, the designer of the board in the Sun-1.

Interesting fact

Yeager said that he gave his part of the Stanford license royalties back to his department.
