This course is for all personnel who are responsible for the management, design, implementation, growth, and troubleshooting of TCP/IP networks. Those with responsibility for security and disaster recovery will also benefit.

While completion of our Understanding TCP/IP course is not a prerequisite, it is assumed that all students will have an equivalent level of knowledge.

After completing this class, students will be able to:

• Describe in detail the TCP/IP architecture and protocols together with their use in corporate networks.
• Describe the present state of routing and understand proposed changes to IP, and their implications.
• Set up and maintain a domain system within a company network, and link a company internet to the global Internet.
• Understand the security issues concerning today's networks, whether Internet connected or otherwise, and advise management on IT security policy.
• Understand the issues surrounding network performance and troubleshooting, as well as the network monitoring tools that are available to help address these issues.
• Discuss how the Internet can be used to improve a company's information gathering and external dissemination strategies.
