Switching To Voip [Ebook-CHM]

More and more businesses today have their receive phone service through Internet instead of local phone company lines. Many businesses are also using their internal local and wide-area network infrastructure to replace legacy enterprise telephone networks. This migration to a single network carrying voice and data is called convergence, and it's revolutionizing the world of telecommunications by slashing costs and empowering users. The technology of families driving this convergence is called VoIP, or Voice over IP.

VoIP has advanced Internet-based telephony to a viable solution, piquing the interest of companies small and large. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. But the real enterprise turn-on is how VoIP empowers

businesses to mold and customize telecom and datacom solutions using a single, cohesive networking platform. These business drivers are so compelling that legacy telephony is going the way of the dinosaur, yielding to Voice over IP as the dominant enterprise communications paradigm.

Cisco Press Cisco Network Admission Control Volume II [Ebook-PDF]

Network Admission Control (NAC) is designed to prohibit or restrict access to the secured internal network from devices with a diminished security posture until they are patched or updated to meet the minimum corporate security requirements. A fundamental component of the Cisco® Self-Defending Network Initiative, NAC enables you to enforce host patch policies and to regulate network access permissions for noncompliant, vulnerable systems.

Cisco Network Admission Control, Volume II, helps you understand how to deploy the NAC Framework solution and ultimately build a self-defending network. The book focuses on the key components that make up the NAC Framework, showing how you can successfully deploy and troubleshoot each component and the overall solution. Emphasis is placed on real-world deployment scenarios, and the book walks you step by step through individual component configurations. Along the way, the authors call out best practices and tell you which mistakes to avoid. Component-level and solution-level troubleshooting techniques are also presented. Three full-deployment scenarios walk you through application of NAC in a small business, medium-sized organization, and large enterprise.
