Passage-End Analysis

Abstract. Passage-end calculations are a new style of passage measurement for eXtended Stochastic Probes (XSP) [1] which add the ability to split the analysis into several cases depending on conditions which hold at the end of a passage. This makes it possible to separate successful responses to a request from negative responses, timeouts or other failures. This allows the expression of service level agreements such as: “At least 90 percent of all requests receive a response within 10 seconds and at least 60 percent of all such requests are successful.”
