Description

As converged networks and mobility become more and more important in daily business, these technologies need to be optimized in order to support business requirements.

You will learn about the new Cisco Intelligent Information Network model (IIN) and the Cisco Service-Oriented Network Architecture (SONA) as architectural frameworks for converged networks.

You will gather VoIP network essentials and focus on the VoIP-related challenges in such networks. In order to ensure the quality in a converged network, you will deal with concepts and implementation methods for Quality of Service (QoS). Finally, you will face the evolution of wireless security standards, and describe elements of a Cisco wireless LAN (WLAN) network. You will work on case studies and several labs based on the Cisco Integrated Services Routers (ISR) related to the converged network topics.
