20090316719 | METHOD FOR MANAGING MECHANISMS TO ENHANCE TRANSMISSION OF DATA STREAMS IN A TUNNEL, CORRESPONDING COMPUTER PROGRAM PRODUCT, STORAGE MEDIUM AND TUNNEL END-POINT - A method is proposed for the management of mechanisms to enhance data stream transmission on a tunnel supported by a main communications network, the transmission of each stream being done according to a frame transport protocol with acknowledgment, the tunnel being implemented between first and second tunnel end-points connected respectively to first and second sub-networks, each stream being transmitted from a sender device to a receiver device through the tunnel, one of the devices which are the sender device and the receiver device being connected to the first sub-network and the other being connected to the second sub-network. The method comprises the following steps performed by the tunnel end-point for a given stream: first partial determining of a nature and a location of a problem of transmission for the given stream enabling first pieces of information to be obtained on a problem by analysis of the given stream; receiving second pieces of problem information coming from the second tunnel end-point and resulting from a second partial determining of the transmission problem performed by the second tunnel end-point; final determining of the nature and location of the transmission problem by combination of the first and second pieces of problem information; managing the transmission enhancement mechanisms as a function of the result of the final determining. | 12-24-2009 |

20100290479 | METHOD AND DEVICE FOR PARAMETERIZING A BRIDGE WITHIN A COMMUNICATION NETWORK - In order to parameterize, within a communication network, a bridge to be put in communication with at least one element to be connected to said bridge, said bridge comprising at least one created port, a parameter representing a predetermined waiting period and corresponding to a time for detection by said bridge, during a phase of listening to the data received by said at least one created port, of the presence of any communication loop within said network, is determined; a filtering of said at least one created port is activated, said filtering being adapted to prevent the sending and reception by said at least one created port of inter-bridge management messages; the bridge is configured with said parameter thus determined; a new port of said bridge is created with a view to setting up communication with said at least one element; and said filtering is deactivated. | 11-18-2010 |
20110060974 | METHODS AND DEVICES FOR TRANSMITTING A DATA STREAM AND CORRESPONDING COMPUTER READABLE MEDIA - A data stream is transmitted from a transmitting device to a receiving device via a communication network. Data of the data stream is transmitted to the receiving device by using a transport protocol without data acknowledgement. In a transmission method, parity-encoding parameters for parity encoding a data set of the data stream is determined via the transmitting device. The transmitting device also generates parity data from the data set by using the determined parity-encoding parameters. The transmitting device further transmits the generated parity data to the receiving device via the communication network by using a transport protocol with data acknowledgement. | 03-10-2011 |
20110141904 | METHOD AND APPARATUS FOR TRANSMITTING PACKETS OF A TWO-WAY PASSENGER DATA STREAM - A method is proposed for transmitting packets of a two-way passenger data stream set up between first and second terminal devices. The passenger stream is compliant with a passenger transport protocol with acknowledgement defining a plurality of packet categories, and is intended to be encapsulated by a manager device according to an encapsulating transport protocol with acknowledgement. The manager device obtains a packet of the passenger stream transmitted from the first terminal device to the second terminal device, makes a first check to see if the packet obtained belongs to at least one predetermined category among the plurality of packet categories and, in the event that the first check is positive, encapsulates at least one part of the data of the obtained packet according to an encapsulating transport protocol without acknowledgement. | 06-16-2011 |
20130208708 | Method and device for collaborative data communication in a radio network - The present invention relates to communication between collaborative nodes configured to collaboratively communicate in a radio network. A corresponding method comprises: sending, by each active node of the set of collaborative nodes, an RTS message for the same transmission slot; sending, by one of the active nodes, referred to as coordinator node, a CTS message to acknowledge reservation of said transmission slot on behalf of all the active nodes, upon receiving the RTSs; wherein the transmission slot is divided, based on the sent RTSs, into sub-slots for respective active nodes to transmit data packets. The invention provides an improved use of the reserved transmission slot, and a reduced waste of reserved time. | 08-15-2013 |
