Network Overview - Q-Bits International
Q-Bits International has recently adopted Cisco’s strategy for converging voice, video, and data onto a single
network infrastructure using the Cisco AVVID (Architecture for Voice, Video and Integrated Data). Using
Cisco AVVID, Q-Bits has converged its two networks―its data network and its proprietary voice private
branch exchange (PBX) system―onto an open, standards-based network infrastructure.
Dean Jones, a lead network engineer for Q-Bits, has been tasked with verifying the policies behind the
network redesign as well as the day-to-day performance of the new network. He has decided that he needs
visibility into the traffic traversing the network to determine whether or not the rollout has been successful.
He knows that he needs the ability to determine the utilization of the network, but he also wants to know
which applications and hosts are using network resources. In addition, he needs to verify the performance of
voice applications and the new QoS implementation (using Differentiated Services). In short, he needs to
verify that the network has been designed correctly and configured to meet defined polices and requirements.
He has decided to deploy a single NAM card (NAM-1 or NAM-2) in the company headquarters distribution
switch and a branch NAM (NM-NAM) in the core router at the branch facility to help assess the network
performance.
Dean knows that with the one NAM card at each site, he can begin to analyze traffic to determine whether or
not the network meets policy and performance requirements.
