TROUBLE DIAGNOSIS APPARATUS AND METHOD FOR APPLICATION DELIVERY CONTROLLER

摘要

The present invention relates to an apparatus and a method for diagnosing troubles of an application delivery controller, capable of effectively diagnosing load dispersion troubles and response time delay troubles and has an effect for accurately diagnosing the dispersion troubles and the server response time delay troubles based on a virtual server without a decline in service quality. Also, the method has an effect for effectively determining the possibility of trouble occurrence by obtaining processing time or load dispersion operation for an explicit request by separating the operation of the virtual server for a user request from the operation of a real server based on a TCP flag on a transmission layer by collecting packets inserted into the application transmission controller.
