Disclosed approaches eliminate involving a bus interface in polling by the host computer system and the peripheral component for events to coordinate direct memory access (DMA) transfers. The host polls main memory for DMA events communicated by the peripheral component, and the peripheral component polls local registers for DMA addresses to initiate DMA transfers. DMA transfers are initiated by the host storing main memory addresses in the local registers of the peripheral component, and DMA events generated by the peripheral component are stored in the main memory.

Direct memory access circuitry and method

A database proxy includes a computing device and a hardware-accelerated database proxy module. The computing device and the database proxy module. The database proxy is configured to receive a write request from a client; store the write request in a commit log in a first non-volatile memory device; in response to storing the write request in the commit log, return to the client a signal acknowledging success of the write request; store the write request in a cache in a second non-volatile memory device; cause the write request to be written in a database store; and based on a first determination that the write request is stored in the cache and on a second determination that the write request is written in the database store, remove the write request from the commit log.

Persistence of write requests in a database proxy

A database proxy includes a computing device and a hardware-accelerated database proxy module. The computing device includes one or more processors, memory, a first bus interface, and a network interface coupling the database proxy to one or more networks. The database proxy module includes a second bus interface coupled to the first bus interface via one or more buses, and a request processor. The database proxy is configured to receive a database read request from a client via the one or more networks and the network interface; forward the database read request to the request processor using the one or more buses; process, using the request processor, the database read request; and return results of the database read request to the client. In some embodiments, the computing device or the database proxy module further includes a flash memory interface for accessing one or more flash memory devices.

System and method for a database proxy

A database proxy includes a request processor, a cache, a database plugin, and interfaces for coupling the database proxy client devices, other database proxies, and database servers. The request processor is configured to receive a read request from a client, determine whether the read request is assigned to the database proxy, and return results of the read request to the client. When the read request is not assigned to the database proxy, the read request is forwarded to another database proxy. When the read request is assigned to the database proxy, the read request is processed using data stored in the cache when the results are stored in the cache or forwarded to the database plugin, which forwards the read request to a database server, receives the results from the database server, and returns the results to the request processor for storage in the cache.

A user interface to a network simulator facilitates the use of application layer parameters and application layer logic. The user interface is configured to allow the user to define the input in a graphic form, or a text/programming form, or a combination of both. The user interface provides common graphic forms for both inputting the data to the simulator as well as for displaying the resultant data from the simulator. In response, the simulator and user interface may provide updated information to reflect the impact of changes made to application layer parameters and logic.

Application level interface to network analysis tools

A user interface to a network simulator facilitates the use of application layer parameters and application layer logic. The user interface is configured to allow the user to define the input in a graphic form, or a text/programming form, or a combination of both. Preferably, the user interface provides common graphic forms for both inputting the data to the simulator as well as for displaying the resultant data from the simulator, thereby easing the progression from the analysis of output from one simulation to the generation of new input for a subsequent simulation.
