Network Protocol Specialists, LLC will be presenting two workshops at InterOp in New York this year.

Thursday December 15, 2005

Length: 1 Day

Abstract: This course covers how to troubleshoot Ethernet and switched networks. In most cases, networks are designed and installed, but never thoroughly tested to make sure they are performing as they were designed. The instructor reviews the operation of Ethernet and the types of errors that typically occur. Ethernet topics include Ethernet Signaling, Fast Link Pulse, CRC/Alignment Errors, Collisions, and Fragments. The switching portion of the course examines the basics of switch and spanning tree operation. This overview provides the basis for covering troubleshooting techniques in the switched environment. Plan to leave this course with the skills necessary to successfully test and troubleshoot the physical and data link layers of today's Ethernet networks.

Course Outline
• Overview of Ethernet operation
• Impact of duplex problems
• Measuring network performance

Abstract: Every company has one, the application that worked well on the LAN, but failed miserably when you moved onto the WAN. Most people blame the network for the poor performance, when in fact it has more to do with how the application was written. This course covers those factors you must consider when deploying applications in Wide Area Network environments. The instructor uses both WAN emulation and application analysis software to demonstrate how to evaluate an application's performance. Learn the difference between a latency dependent application and bandwidth dependent application. Case studies illustrate the difference between those applications that run well over WANs and those that don't. This session is a must for anyone who wants to roll out a new application or determine why an existing application is performing poorly.

Course Outline
• The language of application analysis
• Impact of latency on application performance
• Impact of bandwidth on application performance
• Using WAN emulation to predict application response time
• Successfully capturing application traffic
• Application analysis software
• Analyzing applications
• Report preparation
• Challenges of multi-tiered applications
• Case studies


Who Should Attend
• Application developers
• Network administrators
• Network analysts
• Network designers
