A computer implemented method, apparatus, and computer usable program code for processing data packets. A set of data fragments are received at the data processing system to form a set of received data fragments. Assembly of the set of data fragments is initiated into a data packet, and a determination as to whether the data packet is an incomplete data packet. Responsive to a determination that the data packet is an incomplete data packet, the incomplete data packet is filled with at least one character to form a final data packet. The final data packet is forwarded to the target.

Methods and devices for processing incomplete data packets

A computer implemented method for obtaining a secure route. A trusted host sets a node security association for a trusted host. The trusted host receives, at the trusted host, a client communication request directed to a destination host. The trusted host builds a secure route query comprising a trusted host address, a destination host address, and at least one security level, to form at least one secure route. The trusted host sends packets from the trusted host to the destination host based on the at least one secure route. The packets are responsive to the client communication request, and the packets each have a security label that matches the security level.

A multi-display system and method supporting differing accessibility feature selection provides a suitable display for a user with limited visual acuity, while providing a second display having a different accessibility feature set to a second user. An application or operating system checks selected accessibility features and display settings corresponding to each graphical display device and generates multiple graphical outputs in conformity with program output and the corresponding accessibility features and display settings for each device. One graphical display may be a personal computer display and the other a projector, so that an accessible desktop can be presented to the presenter, while the presentation can be shown with a desired set of attributes. The operating system may support the above-described operation by generating the multiple display outputs from the accessibility settings and a single program output. Alternatively, an application can generate two display outputs in conformity with accessibility selections.

A method and apparatus are provided for use with a SEA or other bridge device, which is positioned between virtual and physical LANS and is adapted to monitor connection setup packets. If the SEA detects such a packet, it determines whether it can accommodate the MSS value listed in the packet. In one embodiment, a method is provided for implementation by a bridge device positioned to transfer data packets between a specified LPAR system arid a specified host. The method comprises the step of detecting a packet that is transmitted to the bridge device, in order to set up a connection between the LPAR system and the host. The method further comprises determining whether the detected packet indicates an initial MSS value for the connection that is greater than a prespecified MSS value. Upon determining that the detected packet indicates an initial MSS value that exceeds the prespecified MSS value, the packet is altered to establish the prespecified MSS value as the MSS value for the connection.

A dynamically-enforceable application-controlled quasi-reliable extension to TCP permits a client application to dynamically set a percent loss tolerance for data transmission reliability through network input/output system calls to the TCP, thereby programming the transport layer to optimistically acknowledge non-critical missing frames. The reliability requirement can be dynamically set within TCP to the level of reliability required for specific data frames within the data stream during the data transfer. Based on this loss tolerance specified, the TCP layer makes a determination whether to trigger a retransmission or continue delivering out-of-order frames to the application. A forced acknowledgement frame is sent for each missing packet until the number missing packets causing forced acknowledgments within the current receive buffer frame exceeds the loss tolerance. This process avoids needless retransmissions and permits the TCP data flow and sliding window to advance uninterrupted, thereby providing substantial performance benefits to network throughput.

Method, system and article for client application control of network transmission loss tolerance

Disclosed is a virtual world server receives an update signal corresponding to an RFID tag. The virtual world server determines an RFID tag identifier, an RFID reader identifier, and an associated asset name from the update. The virtual world server looks up a virtual area associated with the RFID reader identifier. The virtual world server teleports a virtual asset associated with the RFID tag identifier to a virtual area in the virtual world. The virtual world server renders a model of the asset in a virtual world based on an avatar perspective.

Determining availability of a destination for computer network communications that include providing on a caching device a destination availability cache comprising at least one cache entry representing availability of a destination and providing, from the caching device to a source, through computer network communications, information indicating the availability of the destination. In typical embodiments, the cache entry comprises a network address of a destination device and a time limitation for the cache entry.

A method, computer program product, and data processing system for efficiently discovering and storing path MTU information in a sending host are disclosed. In a preferred embodiment, two path MTU tables are maintained. One path MTU table contains MTU values corresponding to the first-hop routers associated with the sending host. The other path MTU table contains MTU values corresponding to individual destination hosts. When the sending host needs to send information to a destination, it first consults the MTU table associated with individual destination hosts. If an entry for that destination host is found in the table, the sending host uses that MTU value. If not, the sending host consults the MTU table for the first-hop router on the path to the destination host and uses that MTU value. If that MTU value is too high, a new entry is made in the host-specific MTU table for the destination host.

Efficient path maximum transmission unit information discovery and storage

Responsive to receiving a request for a data communications connection, a data communications module of a receiver determines whether a sender of the request is local or remote with respect to the receiver. The data communications module also determines whether a location response flag indicates local or remote. If the relative location of the sender with respect to the receiver corresponds with the location response flag, then the data communications connection is allowed. Otherwise, the connection is not allowed.

Network location based processing of data communication connection requests

A method in a data processing system for reducing the learning curve of a transmission control protocol connection. A domain name system is queried for information. The information and a previously used transmission control protocol parameter for a transmission control protocol connection are received from the domain name system. The information and the previously used transmission control protocol parameter are used to configure a current transmission control protocol connection.
