摘要:
A network switch having a hybrid switch architecture, which is scalable to increase connectivity, buffering, and bandwidth by using multiple shared-memory switch fabrics and multiple crossbar switch fabrics. Each of the crossbar switch fabrics is coupled to each of the shared-memory switch fabrics. The shared-memory switch fabrics are configured to store and retrieve packets. The crossbar switch fabrics are configured to distribute and re-collect packets to and from each of the shared-memory switch fabrics. The network switch having a hybrid switch architecture distributes packets from a crossbar switch fabric to the multiple shared-memory switch fabrics to share the distributed packets among the multiple shared-memory switch fabrics.

A system, method and tangible medium for unified exception handling with distributed exception identification includes a packet processing pipeline with at least two processing stages for processing data packets, each of the data packets being processed having an associated exception map in a memory of the apparatus. An exception detector at each processing stage detects whether any exception conditions apply to the data packet at the processing stage, and if so, a bit setter sets, modifies, or resets one or more bits in the exception map associated with exception conditions detected at the processing stage. An exception handler processes the exception map in response to the state of in the exception map after all the processing stages are complete.

Embodiments of the invention provide a programmable FSA building block, having a number of programmable registers and associated logic implemented therein, that provide the capability of contextually evaluating complex REs of arbitrary size against multiple data streams. Embodiments of the invention provide fully programmable hardware in which all of the states of an RE are instantiated and all of the states are fully connected. For one embodiment, the building blocks have a fixed number of states to facilitate implementation on a chip. For such an embodiment, an RE having an excessive number of states is implemented on two or more FSA building blocks and the FSA building blocks are then stitched together to effect evaluation of the RE. For one embodiment, two or more REs having a number of states less than the fixed number of states of a building block may be implemented with a single building block.

Embodiments of the present invention enable and facilitate radio access technology based call control. For example, a method for call control is described. A call request that includes a call number is received. A call type of the call request is identified based on the call number. A radio access technology associated with the call number and the call type is determined. A call is performed using the radio access technology associated with the call number and the call type. In some instances, embodiments can be used for emergency type calls. Other aspects, embodiments, and features are also claimed and described.

摘要:
A system, method, and computer readable medium containing computer readable instructions for displaying pop-up accelerator key symbols that indicate accelerator keys that may be activated by a user to select a user selectable portion in a graphical user interface to initiate an option corresponding to the user selectable portion. When a user holds down the “ALT” key, the pop-up display includes a letter, number or other symbol that, when depressed (alone or with the “ALT” key), functions to select an option. Pop-up symbols may also be provided for selecting a group of icons and presenting symbols for each group of icons when a user selects the group symbol corresponding to that group of icons.
