Description

When you are migrating to a VoIP network, all network requirements, including power and capacity planning, must be examined so that voice is seamlessly integrated into the existing network.
IP telephony services provided over the campus infrastructure must have mechanisms set in place to differentiate traffic types and to offer priority processing to delay sensitive voice traffic. Congestion avoidance techniques, quality of service (QoS), and high availability also need to be implemented to ensure an optimal flow throughout the network.
This course covers how to plan for support of voice in a campus network. Congestion considerations for voice and video traffic in relation to bandwidth consumption are explained. Quality of service (QoS) policies that mark and qualify traffic as it traverses the campus switch blocks and the creation of specific voice VLANs to separate voice traffic from other data to ensure that it is carried through the network with special handling and with minimal delay are also covered.
