摘要:
A method, a system and computer readable medium of securely receiving data on a user's system from a web broadcast infrastructure with a plurality of channels. The method includes encrypting the data using a first encrypting key, wherein the first encrypting key is self-contained with all the information necessary to decrypt the data encrypted with the first encrypting key and encrypting the first decrypting key, using a second encrypting key. Next promotional metadata related to at least part of the encrypted data on a first web broadcast channel for reception by at least one user's system is broadcasted. Broadcasting at least part of the encrypted data over a second broadcast channel and transferring the encrypted first decrypting key, which has been encrypted with the second encrypting key, to the user's system via a computer readable medium.
摘要:
A digital rights management system for controlling the distribution of digital content to player applications. The system comprises a verification system, a trusted content handler, and a user interface control. The verification system is provided to validate the integrity of the player applications; and the trusted content handler is used to decrypt content and to transmit the decrypted content to the player applications, and to enforce usage rights associated with the content. The user interface control module is provided to ensure that users of the player applications are not exposed to actions that violate the usage rights. The preferred embodiment of the present invention provides a system that enables existing content viewers, such as Web browsers, document viewers, and Java Virtual Machines running content-viewing applications, with digital rights management capabilities, in a manner that is transparent to the viewer. Extending content viewers with such capabilities enables and facilitates the free exchange of digital content over open networks, such as the Internet, while protecting the rights of content owners, authors, and distributors. This protection is achieved by controlling access to the content and constraining it according to the rights and privileges granted to the user during the content acquisition phase.

Techniques for globally managing systems are provided. One or more measurable effects of at least one hypothetical action to achieve a management goal are determined at a first system manager. The one or more measurable effects are sent from the first system manager to a second system manager. At the second system manager, one or more procedural actions to achieve the management goal are determined in response to the one or more received measurable effects. The one or more procedural actions are executed to achieve the management goal.
摘要:
Coordinating tasks of performance management and application placement management in a dynamic fashion by: estimating capacity needs for various service classes of service requests; computing desired capacities of at least one application for said service requests; deciding whether the desired capacities are satisfied by a current application placement; making no change to current application placement if the desired capacities are satisfied; determining a new application placement based on the desired capacities and a projected load if the desired capacities are not satisfied; computing corresponding capacity constraints for all pairs of service classes and servers; and computing an optimal allocation of capacities among the service classes so as to optimize a quality of service.
摘要:
Apparatus, systems and methods for service and/or business for coordinating tasks of performance management and application placement management in a dynamic fashion. An example process is dynamic in the face of fluctuations in the request load to the distributed computer system and the periodic adjustments to the placement of applications onto servers in said distributed computer system. There are two opposite functional flows in said process: a demand estimation function and a capacity adjustment function. The coordination system involves two subsystems: a demand estimator and a capacity adjuster, along with appropriate interfaces to of the performance manager and the application placement manager. This results in application placement process reacting quicker to demand fluctuations, performance guarantees are better met by rearranging the resources to be allocated to the various classes of service, and the management system works in an unsupervised mode, thus reducing manual administration costs and human errors.
摘要:
A decentralized process to ensure the dynamic placement of applications on servers under two types of simultaneous resource requirements, those that are dependent on the loads placed on the applications and those that are independent. The demand (load) for applications changes over time and the goal is to satisfy all the demand while changing the solution (assignment of applications to servers) as little as possible.
摘要:
A computer implemented method, apparatus, and computer usable program product for managing a distributed software application. The process identifies metadata describing a set of dependencies of a set of software components in the distributed software application from data associated with the set of software components. The process then identifies a sequence for changing an operational state of the set of software components of the distributed software application from the metadata to form an identified sequence. Thereafter, the process changes the operational state of the set of software components using the identified sequence.
摘要:
System for managing a life cycle of a virtual resource. One or more virtual resources are defined. The one or more defined virtual resources are created. The created virtual resources are instantiated. Then, a topology of a virtual resource is constructed using a plurality of virtual resources that are in at least one of a defined, a created, or an instantiated state.
摘要:
Techniques for improving application server performance and availability are provided. In one aspect, a method of monitoring the health of one or more application servers comprises the following steps. One or more health classes are specified, each of the one or more health classes defining one or more health policies for the one or more application servers. At least one of the one or more health policies is monitored. Violations, if any, of the one or more health policies are detected.
摘要:
A method for receiving digital content data on a user's system for playing or recording, the content data being compressed and encrypted with a first encrypting key, said method comprising the steps of: tuning a receiver to a selected frequency; receiving content data through a broadcast transmission at the selected frequency; assembling the content data that is received; and transferring the content data to a player for playing the content data after all the content data has been received. In accordance with another embodiment of the present invention, an information processing system and computer readable medium is disclosed for carrying out the above method.
