Course Overview TCP/IP has been deployed on virtually every type of hardware and software platform available today and forms the backbone of the Internet. As a result, this popular protocol suite has become the standard for building multivendor intranets and internets. This course provides a comprehensive technical introduction to TCP/IP. Extensive hands-on exercises provide the practical experience needed to configure a host, employ TCP/IP tools, use application services, and access TCP/IP-based internetworks. Audience This course is valuable for anyone working with TCP/IP protocols or involved in developing or migrating to TCP/IP networks or accessing Internet services. Familiarity with local area network concepts and either Windows or UNIX is assumed. Skills Gained - Configure hosts and access internetworks using TCP/IP protocols
- Identify the role of each TCP/IP component
- Use all major TCP/IP application services, including: FTP, TELNET, HTTP and NFS
- Avoid common internetworking problems
- Troubleshoot TCP/IP networks using protocol analysis techniques
- Employ popular Internet/intranet tools: FTP, Web browsers, WWW and others
