Abstract: A method for transmitting data from an on-premise component to an off-premise computer image includes: sending a message from the off-premise computer image to an off-premise server and recording an address of the off-premise computer image; sending a message from the off-premise server to the off-premise computer image with instructions for the off-premise computer image to connect to a specific unsecure port of the off-premise server; identifying a connection to the specific unsecure port of the off-premise server within a selected time interval; verifying the recorded address of the off-premise computer image; sending from the off-premise server a message to an on-premise connector to transmit the requested data using the specific unsecure port of the on-premise component if the off-premise computer image is verified and the connection is identified within the selected time interval; and transmitting the requested data using the specific unsecure port of the on-premise component.

Abstract: A system for correlating communication packets across different communication networks includes a first monitoring agent in a first network for collecting local identifying information of a communication packet at a communication node. The first monitoring agent pairs the local identifying information with a public identifying information of the packet for a second network. The first monitoring agent further adds a timestamp to the collected information. A second monitoring agent in the second network receives a communication packet from the communication node and collects public identifying information of the packet. The second monitoring agent adds a time-stamp to the collected information. A third monitoring agent in the second network receives the information collected by the first and the second monitoring agents and correlates packets based on the received information.

Abstract: Prior to a first primary machine image being cloned to a first secondary machine image and a second primary machine image being cloned to a second secondary machine image, a controller determines that the first primary machine image communicates with the second primary machine image. Cloning of the first primary machine image to the first secondary machine image and of the second primary machine image to the second secondary machine image is such that communication from the first secondary machine image to the second primary machine image is not directed to the second secondary machine image. Afterwards, a software agent running on the first secondary machine image changes a global machine image-wide hostname file at the first secondary machine image, so that the communication from the first secondary machine image to the second primary machine image is now directed to the second secondary machine image.

Abstract: A computer-based system and article of manufacture utilizing a single response time monitor, located on a non-origin node of a public or private network, for measuring the total roundtrip response time of a set of requests resulting from an original request having embedded HTML frames. The response time monitor builds a relationship tree for the original request and its embedded HTML frames. For each request from the set of requests resulting from the original request, including requests for the embedded HTML frames, the method uses the response time monitor to detect a start time and end time of each component of the request's roundtrip response time in order to calculate each component's duration. Later, the response time monitor calculates the total roundtrip response time by adding together the duration of all components of the original request and all its additional requests that have the same network address and port number.

Abstract: A method for measuring a network connection's response time, of a given connection, and methods for adapting the delivery of information, based on that measurement, are provided for the purpose of delivering that information faster and more efficiently over the network. The speed of a network connection is determined. Thereafter, information is obtained across the network connection based on the speed of the network connection. The size of the information to be obtained decreases as the speed of the network connection decreases.

Abstract: A Fast method of retrieving Internet web pages based on pre-caching of web pages and their objects. Access by web browsers to these objects are faster since the objects are available in the web browser's local memory cache in advance of actually needing them. Thus, when the web browser needs these objects, no network delays are experienced due to having to get them from the web server located some distance away over the Internet. In addition, a computer efficient method is provided that allows for the statistical selection of which objects to pre-cache. This pre-caching method avoids excessive pre-caching of objects that are statistically insignificant but costly in their use of computer resources. Thus, with pre-caching only the objects most likely to be used in subsequent web browser interactions will take up the computer resources in the pre-caching process.

Abstract: A method, apparatus, and article of manufacture for measuring a round trip response time for a transaction performed by a computer in a network environment. The method comprises the steps of starting a software timer when a transaction is initiated at a browser of the computer, and sending the transaction to a server in the network environment. The server services the transaction, and generates a response to the transaction. When the response is received at the browser the software timer is stopped. The start time is subtracted from the stop time to calculate a round trip response time.

Abstract: A method, apparatus, and article of manufacture for measuring end-to-end response time for a transaction performed by a computer is disclosed. The method comprises the steps of monitoring messages inbound from and outbound to a given application in a computer. A start time is assigned when a first message is inbound towards the given application. A stop time is assigned when a second message, sent in response to the first message, is outbound from the given application. The end-to-end response time is calculated by subtracting the start time from the stop time.

Abstract: An end-to-end response time measurement method monitors the performance of a computer program by measuring the time between related messages that traverse inbound and outbound message queues.
