Everett, Wash.-based Fluke Networks recently announced the availability of a new publication, the Application Troubleshooting Guide. This new guide helps network engineers understand how applications flow across the network and how they fail and provides a five-step process for troubleshooting application problems when they occur.

The 94-page guide helps users solve the frustrating problem of identifying whether the cause of performance degradation is coming from the client, the servers, the network, or the behavior of the application itself, and covers the basics with sections on the TCP Protocol, the life of a packet, and DNS lookup, providing network engineers with the fundamentals needed to understand and triage problems.
