IP, Networking and VPNs (Technical & Support Focus) [Two or Three Days]
Prerequisites: Basics of Data (Packet-Switched) Networks or comparable basic understanding of data technologies
Who should attend:
Any employee who needs a detailed understanding of the applications, functions, systems, and workings of an IP-based Data Network
Description:
This course teaches the student the details of how an IP-based network functions. The student will be taught the terms, "myths", realities, functions and applications of an IP-based network (e.g.: Internet, Intranet, and Extranet). Since data-networking professionals expect competency in their vendors, this course will teach the precise terms and architectures of data networking (and how they're used in design and support activities). After learning IP Protocol Basics and how IP packets are routed across a global network, the following sections will show supporting technologies (physical access, Frame Relay, and ATM) and overviews of different service features, such as Voice over IP, Network Security and Virtual Private Networks.
