| 20080244017 | Filtering application messages in a high speed, low latency data communications environment - Methods, systems, and products are disclosed for filtering application messages in a high speed, low latency data communications environment that include: receiving an application message in a transport engine of a message receiving device from a message transmitting device, the application message having a message contents label and a collision indicator, the message contents label representing contents of the application message, the collision indicator specifying whether the message contents label represents different contents in at least one other application message; determining, by the transport engine, whether contents of the application message satisfy a transport layer constraint in dependence upon the message contents label; providing, by the transport engine, the application message and the collision indicator to messaging middleware of the message receiving device if the contents of the application message satisfy the transport layer constraint; and administering the application message, by the messaging middleware, in dependence upon the collision indicator. | 10-02-2008 |
| 20080310423 | Synchronization of Message Stream in a Multi-tier Messaging System - A group communication service is adapted for multi-point to multi-point communication. Identical message streams are received by a tier of processing servers from a tier of sources. The processing servers deliver the message streams to a tier of destinations. The group communication service enables the processing servers to deal with newly added message streams and deleted message streams while preserving total ordering. | 12-18-2008 |
| 20080310444 | Group Communication System Achieving Efficient Total Order and State Synchronization in a Multi-tier Environment - A group communication service maintains synchronization limiting the group to the processing entities that receive a plurality of source message streams from sources outside the group and transmit delivery message streams to destinations that are outside the group. Synchronization of message ordering and other state synchronization directives are communicated from a leader exclusively to other group members. Once having declared themselves to be synchronized and active by a reply protocol message, which is an opaque object and is interpreted by an application layer, the processing entities independently process the source message streams in accordance with the order specified in the directives, without requiring additional sequencing information from another processing entity. | 12-18-2008 |
| 20090052318 | SYSTEM, METHOD AND COMPUTER PROGRAM PRODUCT FOR TRANSMITTING DATA ENTITIES - A method, system and computer program product for transmitting data entities, the method includes: receiving data entities to be transmitted over multiple channels; and preventing a transmission of data entities that are to be transmitted over congested channels while transmitting data entities that are to be are to be transmitted over non-congested channels | 02-26-2009 |
| 20100054195 | Efficient Deallocation of Network Resources Based on Network Node Location Extrapolation - Deallocating resources allocated to a network communications session, including extrapolating an expected location of a selected node that belongs to a communications path of a network communications session, determining if the extrapolated location is beyond a predefined range from a neighboring node that belongs to the communications path of the network communications session and that immediately neighbors the selected node along the communications path, and deallocating any resources allocated to the network communications session if the extrapolated location is beyond the range. | 03-04-2010 |
| 20100074255 | Efficient Light-Weight Multicasting Communication Protocol - Efficient Light-Weight Multicasting Communication Protocol A method for communication in a computing environment is provided. The method comprises transmitting a first data packet to one or more receiving units in a first set; receiving one or more acknowledgement messages (ACKs) from one or more receiving units in a second set, wherein the second set is a subset of the first set; removing the first data packet from a queue, in response to receiving at least one ACK from N receiving units within a time threshold; and re-transmitting the first data packet to the first set, in response to failing to receive at least one ACK from N receiving units within the time threshold. | 03-25-2010 |
| 20110016349 | REPLICATION IN A NETWORK ENVIRONMENT - A method for server replication in a network environment is provided. The primary server provides a first service to a client. If the first service involves interaction with a non-deterministic data source, the primary server performs the interaction and provides information about the interaction to a secondary server that is a replica of the primary server. The secondary server uses the information about the interaction to synchronize the secondary server with the primary server. | 01-20-2011 |

| 20110006674 | METHOD FOR FABRICATING NANO-SCALE PATTERNED SURFACES - A method for fabrication of substrate having a nano-scale surface roughness is presented. The method comprises: patterning a surface of a substrate to create an array of spaced-apart regions of a light sensitive material; applying a controllable etching to the patterned surface, said controllable etching being of a predetermined duration selected so as to form a pattern with nano-scale features; and removing the light sensitive material, thereby creating a structure with the nano-scale surface roughness. Silanizing such nano-scale roughness surface with hydrophobic molecules results in the creation of super-hydrophobic properties characterized by both a large contact angle and a large tilting angle. Also, deposition of a photo-active material on the nano-scale roughness surface results in a photocathode with enhanced photoemission yield. This method also provides for fabrication of a photocathode insensitive to polarization of incident light. | 01-13-2011 |
