TCP/IP: Mobility

Duration: 
1 day
Price: 
$695.00
Audience: 

Individuals that need to support mobile users in TCP/IP networks.

Prerequisites
Our “Networking Foundations: Fundamentals Level I” and “Networking Foundations: Fundamentals Level II” are highly recommended or an understanding of networks and data communications. The course assumes familiarity with TCP/IP, such as taught in “TCP/IP: Fundamentals”

Overview: 

A widely popular feature of today’s data communication networks is the ability of users to connect to the network anytime in any place over any medium. However, the core Internet protocols were designed before user mobility and wireless communication links were in widespread use. This course focuses on the challenges that mobility and wireless communication bring to the Internet protocol suite. The course briefly reviews the relevant portions of the IP and TCP protocols, introduces the problems caused by mobility and wireless links, and presents a range of solutions. These span from Internet standards to various commercial and academic solutions, exhibiting a number of design trade-offs in terms of performance or security, for example.
