Disclosed is a technique for performing configuration checking of a network. A network data store is scanned for at least one transaction. At least one event is generated for said transaction. At least one configuration policy is associated with said event. Said configuration policy is compared with configuration data associated with said event. It is determined whether said configuration policy has been violated based on the comparison. Also disclosed is a technique for performing proactive configuration checking of a network. A hypothetical network scenario is received. At least one transaction is generated based on the hypothetical network scenario. A network data store is populated with configuration data for said transaction. At least one event is generated for said transaction using a mapping of events to transactions. Configuration data associated with said event is used to determine whether a configuration policy has been violated. Moreover, disclosed is a technique for performing reactive configuration checking of a network. A request to perform configuration checking on an existing network configuration is received. A network data store is scanned for at least one transaction. At least one event is generated for said transaction using a mapping of events to transactions. Configuration data associated with said event is used to determine whether a configuration policy has been violated. Furthermore, disclosed is a technique for correcting a configuration problem. The configuration problem is detected. It is determined whether there is at least one solution for the configuration problem in a knowledge data store. When it is determined that there is at least one solution in the knowledge data store, automatically selecting a solution to solve the configuration problem. When said solution can be automatically applied, automatically applying said solution. When said solution cannot be automatically applied, notifying a user.

A method for reducing bandwidth used in multiple transmissions on a cellular network includes mapping at least one request of at least one end-device to a unicast channel between server and an intermediary in the network, creating a correlated multicast communication channel between the intermediary and the at least one end-device, and transferring data from the unicast channel to a multicast channel at the intermediary.

A method for scheduling a sequential transmission of a plurality of packets includes estimating a time when each of the plurality of packets waiting to be transmitted will be used by a device targeted to receive the plurality of packets, and mapping the time of each of the plurality of packets to a prioritization among the plurality of packets.

An operator guidance system is provided for an administrator managing a computer network such as a distributed computer system. Fault events reported by a fault management system in the network are enhanced to include topology information about other nodes (such as neighbor nodes, path nodes and/or service nodes) that may have been responsible for the fault. The enhanced events are correlated with configuration commands used in the past to correct faults. A set of guidance rules are developed based on the actions that were taken by the operator in handling previous faults of a similar nature. The guidance rules can be displayed to the administrator to facilitate network fault resolution. Using a set of predefined policies, some of the corrective actions can be performed automatically.

The present invention relates to an ophthalmic diagnostic apparatus. The apparatus comprises: a display means (12) arranged to be worn in proximity to a user's eyes and arranged for displaying images relating to at least one visual function test to a user; a first user interface (14) for providing instructions to a user relating to said at least one visual function test and a second user interface (16) for receiving responses from said user in relation to said at least one visual function test; storage means (22) for storing data relating to said at least one visual function test; control means (18) for transferring said data relating to said at least one visual function test to said display means and said user interface; and output means for outputting a signal responsive to the user responses so as to assist with ophthalmic diagnosis.

The invention is directed to user-friendly multi-lingual text entry using a dynamically reconfigurable keyboard. A method for dynamically reconfiguring a keyboard according to an embodiment of the invention includes: displaying a first set of characters on the keyboard; providing language settings to an upper level system manager of a keyboard driver; communicating reconfiguration information corresponding to the language settings from the upper level system manager of the keyboard driver to a lower level device driver of the keyboard driver; and dynamically reconfiguring the keyboard to display a second set of characters.

An operating system that provides protection domain support is arranged so to be compatible with “well behaved” threads, i.e., threads that obtain all their memory allocations from the operating system, that were written without regard for protection domains. This may be achieved by associating each protection domain with one or more pages of memory, so-called “primary memory pages”, for which the protection domain has read and write access permission. Requests by such a “protection-domain-unaware” thread to the operating system for a memory allocation, e.g., for memory in which to create a data structure, are automatically fulfilled by the operating system from the memory available in the primary memory pages of the protection domain of the requesting thread. The operating system informs the thread of the location of the created data structure, e.g., by passing to the thread a pointer to the data structure. Note that threads may have read and/or write access to memory pages that are not primary pages for their protection domains. Thus, the operating system controls 1) the access permission for each page; 2) the allocation for use as primary pages of pages from “free memory” pages, e.g., memory pages available in the system domain; and 3) which particular pages are primary pages for each protection domain at any particular time.

Embodiments of the present invention provide a method, system and computer program product for split transport control protocol (TCP) flow control management in a cellular broadband network. In an embodiment of the invention, a method for split TCP flow control management in a cellular broadband network is provided. The method includes first determining a context for a packet received as part of a data flow in a base station of a cellular broadband network and then selecting either an end-to-end TCP connection or a split TCP connection to support the data flow. Thereafter, the data flow is routed using the selected connection.
摘要:
An apparatus and method for off-loading application components to edge servers are provided. An application is made edge-aware by defining which components of the application may be run from an edge server, and which components cannot be run from an edge server. When a request is received that is to be processed by an application on an origin server, a determination is made as to whether the application contains edgable components. If so, an edgified version of the application is created. When a request is received that is handled by a component that may be run on the edge server, the request is handled by that component on the edge server. When a request is received that is handled by a component that is not edgable, the request is passed to a proxy agent which then provides the request to a broker agent on the origin server.
