Shares of Juniper, which makes equipment used to direct data traffic in computer networks, fell $15.70, to $140.30.
Nexabit was supposed to catapult Lucent to immediate leadership in the market for ultrahigh-capacity Internet routers -- devices that help direct data traffic.
Hoping to increase its share of business from the world's largest telecommunications carriers, Cisco Systems said Monday that it would unveil on Tuesday its fastest-ever router, a device used to direct data traffic over the Internet.
Therefore, in the situation where the primary networks are overloaded and the secondary networks are light loaded, some primary users can direct their data traffic to the secondary networks for better service experience, and as a reward for the secondary networks, they can access the licensed spectrum bands as long as the QoS of the primary users is satisfied.
When Chambers took over, Cisco had annual sales of $1.2 billion in routers, the boxes that link networks of computers and act as traffic cops for directing data.
One critical piece of networking equipment is the router, which acts as a traffic officer by directing data to the proper destination.
Cisco csco is often cited as a safer Internet play because it essentially provides the web's backbone, making all the routers, switches and connectors that direct data packet traffic from place to place.
That box is capable of directing 322 terabits of data traffic a second, or by Cisco's math, the bandwidth equivalent to downloading every movie ever made in four minutes, or the same data speed requirements as every person in China making a video call at the same time.
McLeodUSA and others built expansive networks to carry voice and data traffic, mostly directed at small and midsize businesses.
BCO makes chips used in optical switches, devices that direct the flow of voice, video and data traffic.
