Abstract:
A system and method for handling client service requests. In one embodiment, a client service request containing a content request directive and request context data is received at a server-side client interface. A request callback object containing the content request directive and the request context is generated. The callback object is issued to a connection agent that interfaces an auxiliary content channel and a transaction service. Responsive to the connection agent receiving the callback object, an asynchronous service request comprising the content request directive is issued to the transaction service and the callback object is registered with the auxiliary content channel. The auxiliary content channel retrieves auxiliary content that has been selected and prioritized in accordance with the request content. The retrieved auxiliary content is sent during servicing of the asynchronous service request by the transaction service. Responsive to retrieval of data satisfying the content request directive, the sending of retrieved auxiliary content is suspending and the data satisfying the content request directive is sent to the server-side client interface.
Abstract:
A method for handling service requests in a data processing system is disclosed. In response to a service request, a priority of the service request is determined by mapping a context of the service request to a service level agreement (SLA). SLA-aware and timeout-conscious and preemptive and replayable lock manager is designed to account for different operational goals and different importance to satisfy various SLAs. An average processing time of the service request is then calculated based on statistical results. The service request will be allowed to process if the determined average processing time meets historical guarantee situations.

Abstract:
A method, apparatus, system, and signal-bearing medium that, in an embodiment, receive a change request from a first client at a first time, where the change request includes a key that identifies a field in a data object. A determination is made that the first client changed the field identified by the key at a second time that is before the first time and that a second client changed the field identified at a third time that is after the second time and before the first time, and the key is sent to the second client. The client receives the key, and in various embodiments invalidates the key in a cache or removes the key from the cache. In an embodiment, the data value of the change request is also sent to the second client, which updates the cache with the data value. In this way, stale data in a cache at a client is either updated or removed.

Abstract:
A method, apparatus, system, and signal-bearing medium that, in an embodiment, route requests to servers based on a synchronization level of data that the servers provide. In an embodiment, synchronization levels that servers provide are determined, a synchronization level that a request requires is determined, a server is selected based on the provided synchronization levels and the required synchronization level, and the request is routed to the selected server. The selection of the server may include selecting a subset of the servers, ordering the subset based on the provided synchronization levels, and selecting the highest synchronization level that is processing less than a threshold number of requests. In various embodiments, the provided synchronization levels are determined based on probabilities that data changes are synchronized between the servers based on distributions of propagation time delays of data changes between the servers, based on distributions of elapsed times between data changes, and based on both distributions.
Abstract:
The present invention provides a service providing device and a service providing method enabling a user to accept the service by utilizing the capabilities of several various devices. An available physical device or a combination of the physical devices is selected for the user based on the service requirement, and the user accepts the service via the selected physical device or the combination of the physical devices. The invention “hides” the physical devices by using a virtual device to provide the service for users. Furthermore, the invention provides a “tailored” virtual device based on the environment around the user, the favorite of user and the requirements of the service, and therefore the invention may provide to the user the “tailored” information suitable for the user. The operating environment of the virtual device according to the invention is dynamically changeable according to the environment around the user, the favorite of user and the requirements of the service, and therefore a seamless service may be provided to the user.
Abstract:
One computer system in a cluster includes a dynamic routing mechanism that receives all incoming messages for the cluster. When a message is received, the dynamic routing mechanism checks its dynamic routing table, and routes a message to the appropriate partition that corresponds to the address of the message. If a resource has been moved to a different partition, the dynamic routing mechanism may route the message to the old partition instead of the new one. In this case, the old partition receives the message, determines whether the message is intended for it, and if not, the partition forwards the message to the appropriate target partition. The partition then notifies the dynamic routing mechanism of the change in location of the resource, which causes the dynamic routing mechanism to update its dynamic routing table to reflect the change in location for the resource.
Abstract:
Efficient search window storage schemes for motion estimation in video signal processing are disclosed. According to one embodiment, motion estimation is carried out as follows: allocating a ring buffer to store at least critical number of macro-blocks of luminance data from a reference frame on the motion estimator, establishing a rule to relate each storage unit of the ring buffer with each of the macro-blocks of the reference frame, initializing the ring buffer by reading in one less than the critical number of macro-blocks from the reference frame, when the macro-block is located next to a border of the reference frame, generating one or more added border macro-blocks and storing into the corresponding position of the ring buffer in accordance with the rule, constructing the search window from the macro-blocks stored in the ring buffer, and conducting motion estimation of the current macro-block of the current frame with the search window.
Abstract:
The present invention provides a multilevel read-only optical disk and the method for producing the same. The multilevel read-only optical disk comprises a plurality of the recording pits, each of the longitudinal sections of the recording pits has a multilevel arbitrary shape; the areas of the longitudinal sections of the recording pits are not identical each other; the area of each of the longitudinal sections of the recording pits is defined by the following formula: S=∫h(x)dx, where S represents the area of each of the longitudinal sections of the recording pits, x represents the coordinate value along the width direction of the recording pits, h(x) represents the pit-depth distribution function of the longitudinal sections of the recording pits and the region of the integration covers the whole longitudinal sections of the recording pits. Furthermore, the run length of the multilevel read-only optical disk is limited. The present invention obtains the advantage of both multilevel storage technology and run length limited (RLL) codes. They can improve prominently the storage capacity and data transfer rate of read-only optical disk without changing the wavelength of the laser and optical numerical aperture, and are most compatible with the conventional read-only optical disk system.
