摘要： A method is disclosed for protecting a network against a denial-of-service attack by inspecting application layer messages at a network element. According to one aspect, when a network element intercepts data packets that contain an application layer message, the network element constructs the message from the payload portions of the packets. The network element determines whether the message satisfies specified criteria. The criteria may indicate characteristics of messages that are suspected to be involved in a denial-of-service attack, for example. If the message satisfies the specified criteria, then the network element prevents the data packets that contain the message from being received by the application for which the message was intended. The network element may accomplish this by dropping the packets, for example. As a result, the application's host does not waste processing resources on messages whose only purpose might be to deluge and overwhelm the application.

摘要： A system that enables automatic version provisioning in heterogeneous application oriented network (AON) architectures is provided. Generally, the specification enables appropriate version configurations to be selected at runtime as needed in an AON environment. More particularly, the subject specification describes the ability of a device (e.g., AON node) to perform and/or select a self-configuration operation based upon the environment and the runtime operation. To facilitate message-based runtime instantiation of the appropriate configuration, the system enables network applicable configurations to be pushed to each of the nodes in the AON architecture.

摘要： A feature phone has two processors that share a display. The display is attached to an applications processor that has a frame buffer for refreshing the display. A base-band processor also runs programs that generate graphics data that is written to a base-band frame buffer. Updates to the base-band frame buffer are sent through a shared-memory interface to a shared memory, and a shared mailbox is written with the message length, triggering a mailbox-interrupt to the applications processor. The applications processor reads the message from the shared memory and updates a copied frame buffer. An overlay engine uses the copied frame buffer to refresh the display when the base-band processor has the focus, or to refresh a smaller base-band window that covers a portion of the display, leaving the rest of the display area for applications-processor graphics data. Rapid switching between the copied and local frame buffer is possible.

摘要： A feature phone has two processors that share a key pad for user input. The key pad is attached to a base-band processor and sends an interrupt to a user-hardware-interrupt UHI driver running on the base-band processor when the user presses a key. When a hot switch indicates that the local base-band processor has the focus, a key-press event is sent to the local kernel to be sent to programs on the base-band processor. When the hot switch indicates that a remote applications processor has the focus, a message for the event is written through a shared-memory interface to a shared memory on the applications processor. A shared mailbox is written with the message length, triggering a mailbox-interrupt to the applications processor. A virtual UHI driver running on the applications processor reads the event message from the shared memory and passes key-press information to programs on the applications processor.

摘要： Methods and systems consistent with the present invention provide a Supernet, a private network constructed out of components from a public-network infrastructure. The Supernet provides channel-specific file system views such that the file system of the Supernet is partitioned on a per-channel basis so that nodes on one channel see a different view of the network file system than the nodes on a different channel.

摘要： A software infrastructure for providing an open digital services marketplace including a naming manager that enables a requesting task to refer to a desired resource using a name which is local to the requesting task and a router that forwards the request to an appropriate handler for the desired resource and that enables at least one additional task to be invoked in response to the request. The infrastructure includes a permission manager that compares a set of access rights of the requesting task to the desired resource to a set of permissions associated with the desired resource such that the access rights are kept separately from the reference to the desired resource. The desired resource, the requesting task, the additional task, and a set of additional components used to handle the request are each modeled as a resource defined by a corresponding set of meta-data which includes a set of attributes and a reference to a grammar for interpreting the attributes.
