Abstract: A method and an apparatus for detection and prevention of a slow response on a network are disclosed. For example, the method selects a router automatically for testing in response to a ticket indicating a slow response, and performs a diagnostic test on the router, wherein the diagnostic test comprises at least one of: a protocol diagnostic test, a circuit diagnostic test or, a congestion diagnostic test. The method then performs at least one remedial step to address a root cause that is identified by the diagnostic test, wherein the root cause is associated with the slow response.
