The married couple
Leonard Bosack and
Sandra Lerner , who worked in computer operations staff at
Stanford University , founded Cisco Systems in 1984. Bosack adapted multiple-
Protocol Router software originally written by
William Yeager , another staff employee who had begun the work years before Bosack arrived from the
University Of Pennsylvania , where Bosack had received his
Bachelor's Degree .
While Cisco was not the first company to develop and sell a
Router (a device that forwards computer traffic from one network to another), it did create the first commercially successful multi-protocol router to allow previously incompatible computers to communicate using different network protocols). As the
Internet Protocol (IP) has become a standard, the importance of multi-protocol routing as a function has declined. Today, Cisco's largest routers are marketed to route primarily IP packets and
MPLS frames.
In
1990 the company went public and was listed on the
Nasdaq stock exchange. Bosack and Lerner walked away from the company with $170 million
{Link without Title} , and later divorced.
Using acquisitions, internal development and partnering with other companies Cisco has made inroads into many network equipment markets outside of routing, including Ethernet switching, remote access, branch office routers, ATM networking, security, IP telephony and others. In
2003 , Cisco acquired
Linksys , a popular manufacturer of
Computer Network ing
Hardware and positioned it as a leading
Brand for the home and the end user networking market (
SOHO ).
Cisco has set up "Cisco Networking Academies" in 150 countries aimed at teaching students to design and maintain computer networks.
