摘要： Methods, apparatus and computer program products implement session-specific URIs for allocating network resources by receiving a request from a user for at least one network resource; assigning a session-specific URI to the at least one network resource for use in identifying the at least one network resource and controlling access to the at least one network resource; updating a network directory service with the session-specific URI; and communicating the session-specific URI to the user. The user communicates the session-specific URI to other participants in the session during which the at least one network resource will be used. After a pre-determined time, the session ends and the at least one network resource is de-allocated by, for example, changing the URI of the at least one network resource. Frequent changes of URIs hinder efforts by unauthorized individuals to gain access to network resources.

摘要： Method, apparatus and computer program product are configured to perform computer monitoring activities; to collect information regarding computer system status during the computer monitoring activities; to detect a problem in dependence on the information collected during the computer monitoring activities; and to determine whether to launch a diagnostic probe when the problem is detected. The monitoring activities may be performed on a periodic or event-driven basis. The determination whether to launch a diagnostic probe is based on a rule included in a hierarchy of rules. The hierarchy of rules is based on problem tickets; system logs; and computer system configuration information.

摘要： Disclosed herein are methods and apparatus that improve the perceived responsiveness of a multi-server web site or web environment to web requests issued by web browsers. In one aspect, the methods and apparatus operate by determining a likely sequence of web pages to be accessed by users. The methods and apparatus then incorporate information identifying web pages and web page content likely to be requested later in the sequence in web pages responsive to web page requests received earlier in the sequence. In one such method, the URL of a second web is incorporated in a first web page that is expected to be requested before the second web page. A web client receiving the first web page will then issue a DNS request for address information corresponding to the URL of the second web page even if no request has been received for the second web page. Thus, the probability of a DNS system cache miss occurring when a web request for the second web page is actually received by the web client is significantly reduced.

摘要： Method, apparatus and computer program product manage a plurality of networks with a single tenant network management tool using virtualization and implement control plane virtualization of the single tenant management tool; data storage virtualization of a data storage apparatus and network address virtualization of an available address range. A virtual machine may be implemented for each network of the plurality of networks to contain an instance of the single tenant management tool. In one implementation, a proxy is used to implement data storage virtualization. In another implementation, separate data storage is maintained for each network and data storage virtualization is achieved by managing the network protocol stack virtualization. The network address virtualization may be implemented using machine-level virtualization or operating-system-level virtualization.

摘要： The present invention provides a method, system and program product for enhancing communications between endpoints. Specifically, the present invention provides mechanisms (e.g., routing controllers either at a network or application layer) that negotiate and specify which network interface to use at each endpoint (both sending and receiving) in multi-homing interface environments. This approach allows the application traffic to be routed through these two specified network interfaces for the better end-to-end QoS. This network interfaces used can also be dynamic changed (e.g., in real-time) to adapt to changing conditions of the network links.

摘要： Disclosed is a method and system for determining one or more performance characteristics of a target server. A command is transmitted from a coordinator to a plurality of clients. The command instructs the plurality of clients to each transmit a request targeting a sub-system of said target server. A response time is then received from each client and a performance characteristic is determined from the received response times.
