Internetworking Protocols; TCP/IP and The Next Generation

Course Objectives And Target Audience
TCP/IP is a subject of increasing interest to information systems professionals involved in, or interested in open architecture interoperability. The importance of these topics has rapidly increased with the growth in client-server systems, and the need for functional connectivity between these kinds of systems across wide area networks. The course has been designed to appeal to:

• people responsible for managing and/or administering TCP/IP LAN, MAN and Enterprise networks
• people responsible for planning network facilities and services -- with multi-protocol application demands
• users of TCP/IP technology: systems analysts, operations personnel, systems programmers, network facilitators ...
• people newly appointed to responsibilities with networks that operate the TCP/IP suite of protocols
• systems analysts and programmers who are anxious to understand the network issues which apply to open, client/server networked IT solutions

What Students Can Expect to Gain From Attending
Students find that Internetworking Protocols; TCP/IP and The Next Generation provides a comprehensive, logical introduction and detailed discussion of the features of these two principal protocols -- and a number of the associated protocols, such as:

• UDP, which is used parallel to TCP in a number of applications
• Application layer protocols, such as Telnet (interactive terminal service), File Transfer Protocol and Simple Mail Transfer Protocol
• System level protocols, like Gateway-to-Gateway (router) route exploration protocols
• Utility services, like PING, NFS Mount and Simple Network Management Protocol

Students will receive an introductory exposure to the Internet's information resources, learn how to navigate the network, and access these sources.
The course has a major focus objective of developing and appreciation of the Next Generation versions of TCP and IP -- and a motivation of why these changes are necessary, how they will be deployed and when they will impact us in the workplace. Related to these developments is the relationship between TCP/IP and the OSI standards -- and the uncertain future of these internationally recognized standards.

The specific terminology of this field is intimidating to beginners. A priority objective of this program is clarification and interpretation of terminology.

Presentation Format
Internetworking Protocols; TCP/IP and The Next Generation is designed as a two-day course -- comprising approximately 12 hours of instruction.

A permanent, comprehensive workbook is included for each attendee -- which in addition to being a work-along class reference document contains a comprehensive glossary, list of recommended reading references and a cross-referenced subject index.

Recommended Previous Knowledge
Newcomers to the field of computer communications will find an exposure to Network Solutions: LANs and LAN Connectivity (or equivalent) will be a useful background to this program.
