Abstract: A computer-based system and method for measuring the roundtrip response time of an original request on a network, utilizing a single response time monitor located on a non-origin node. The method starts the response time monitor on the non-origin node to detect a start time and end time of each component of the original request's roundtrip response time in order to calculate each component's duration. Later, the response time monitor calculates the roundtrip response time by adding together the duration of all components that have the same network address and port number as the original request.

Abstract: Dynamic discovery and reporting of one or more application program topologies in a single or networked distributed computing environment allows IT professionals to maintain processes running on the network. In one embodiment, the dynamic discovery is performed by identifying one or more computers in a computer network, identifying one or more processes on each identified computer that are communicating over the network, and displaying a graphical representation of the topology of the processes communicating over the network.

Abstract: Service requests from client objects in a computer network are processed in accordance with the desirability of use of the transport network available for communication with the server objects so that local platform servers are used whenever possible to avoid data marshalling and unmarshalling. A local memory queue is used to hold the service request for interrogation by the local server. Local memory storage may be used to hold data or other portions of the service request so that only minimal data need be processed by the memory queue.
