By not allowing the storage controller to flush the data from its cache until all of the operations are performed, even a tiny cache attached to the storage controller can reduce the bandwidth and latency of updating the data.
A method and system to transfer a data stream from a data source to a data sink are described herein. The system comprises a trigger core, a plurality of dedicated buffers and a plurality of dedicated buses coupled to the plurality of buffers, trigger core, the data source and the data sink. In response to receiving a request for a data transfer from a data source to a data sink, the trigger core assigns a first buffer and a first bus to the data source for writing data, locks the first buffer and first bus, releases the first buffer and the first bus upon indication from the data source of completion of data transfer to the first buffer, assigns the first buffer and first bus to the data sink for reading data and assigns a second buffer and second bus to the data source for writing data thereby pipelining the data transfer from the data source to the data sink.
Embodiments of the invention may be used to manage message queues in a parallel computing environment to prevent message queue deadlock. A direct memory access controller of a compute node may determine when a messaging queue is full. In response, the DMA may generate an interrupt. An interrupt handler may stop the DMA and swap all descriptors from the full messaging queue into a larger queue (or enlarge the original queue). The interrupt handler then restarts the DMA. Alternatively, the interrupt handler stops the DMA, allocates a memory block to hold queue data, and then moves descriptors from the full messaging queue into the allocated memory block. The interrupt handler then restarts the DMA. During a normal messaging advance cycle, a messaging manager attempts to inject the descriptors in the memory block into other messaging queues until the descriptors have all been processed.
A method for increasing the capacity of a connection table in a firewall accelerator by means of mapping packets in one session with some common security actions into one table entry. For each of five Network Address Translation (NAT) configurations, a hash function is specified. The hash function takes into account which of four possible arrival types a packet at a firewall accelerator may have. When different arrival types of packets in the same session are processed, two or more arrival types may have the same hash value.
A distributed network address translation (NAT) system is used to transport data packets between private and public network domains. A packet modifier substitutes public and private network address information in packets that are crossing between public and private domains to and from the end system. A network application server has an address mapping table and communicates with the packet modifier over a control protocol. The network application server generates address mappings which the packet modifier uses for modification of data packets passing through it.

An example embodiment of the present invention provides a process that uses IP flow information to selectively notify users of an application server of the server's unavailability. In the example embodiment, the process, which might run on a system comprising a router, monitors IP flow records as to dropped packets and learns that an application server has become unavailable. The process then uses the IP flow records to identify active users of the application server, for example, by passing a source IP address to a presence service. Once the process has identified an active user, the process determines a means of notification for the user, which might be through the presence service, and transmits a notification to the user as to the unavailability of the application server. In the example embodiment, the process transmits a later notification as to the availability of the application server, using reverse camp-on functionality.

A system for targeting bulletins to specific electronic devices includes a device management (“DM”) service, one or more electronic devices, and a database for storing bulletins. Generally, the DM service creates a bulletin, associating targeting criteria specifying one or more electronic devices with the bulletin. An electronic device submits a service request to the DM service identifying bulletins previously received (if any) by the device and a device identification number assigned to the device. Using the information from the service request, the DM service queries the database for bulletins available for the device. Upon locating an available bulletin, the DM service notifies the device and after receiving a request for the bulletin from the device, the DM service transmits the available bulletin. Alternately, the DM service can transmit the bulletin without first notifying and receiving a request from the device.
Techniques are provided for desktop streaming over wide area networks.

While one or more blocks of the file are being downloaded or written into the file, the logic is configured to check whether a second sharing mode received in a subsequent request to open the file is compatible with the first sharing mode. If the second sharing mode is not compatible with the first sharing mode, the logic is configured to deny the subsequent request even though in the file system the file is opened in the read-write sharing mode.
Server side internet applications are created by placing interactive server side components (ISSC's) on internet pages. ISSC's encapsulate dynamic page functions including processing of user responses on the server and thus can be reused, which drastically reduces programming effort. The ISSC technique remembers information (in form of an ISSC object) about each ISSC during dynamic page generation on the server. Then, it generates HTML code in a way such that the ISSC event is sent to the server using a conventional HTTP GET or POST request. On the server, the event is then passed to the corresponding ISSC object. All components work without disturbing each other, even when nested or combined. A browser based editor can also be used to place ISSC's on pages and to modify their properties. During dynamic page generation, scripts and handles are embedded into the page that permit editing of the page itself.

To secure HTML mail, the system inserts a resource tag such as a Web bug and/or an HTML frame tag in the message, and it removes and stores a portion of the original e-mail message. The system then sends the modified e-mail message to the recipient. A reader of the message, who may or may not be the original recipient, opens the e-mail message with an e-mail client, which sends a resource request in response to the resource tag. The system receives the resource request and determines whether the reader is authorized to read the original e-mail message. If the reader is authorized to read the e-mail message, then it sends the removed portion to the authorized reader.

In VoIP systems, there is a tradeoff between reducing number of lost packets and end-to-end delay when dealing with jitters. Increasing the jitter buffer space on a mobile wireless terminal reduces the likelihood of lost packets but increases the end-to-end delay. Decreasing the jitter buffer space shortens the end-to-end delay, but there is a greater likelihood of retransmissions and dropped packets. Optimum solution can be arrived at if the jitter buffer space on the mobile wireless terminal can be matched to the scheduling delay. This is difficult to achieve in conventional system because the scheduling delay introduced by the network is unknown to the mobile wireless terminal. Thus, constant adjustment is required. One way to overcome this problem is to apprise the mobile wireless terminal of the maximum scheduling delay.

An OFDM system uses a normal mode which has a symbol length T, a guard time TG and a set of N sub-carriers, which are orthogonal over the time T, and one or more fallback modes which have symbol lengths KT and guard times KTG where K is an integer greater than unity. The same set of N sub-carriers is used for the fallback modes as for the normal mode. Since the same set of sub-carriers is used, the overall bandwidth is substantially constant, so alias filtering does not need to be adaptive. The Fourier transform operations are the same as for the normal mode. Thus fallback modes are provided with little hardware cost. In the fallback modes the increased guard time provides better delay spread tolerance and the increased symbol length provides improved signal to noise performance, and thus increased range, at the cost of reduced data rate.
