摘要:
A method for determining a remote timeout parameter in a network comprising a link between a first bus and a third bus. The link is implemented through a first and a second bridge portal connected respectively to the first and the third bus, and is modelized as a second bus connected to the first bus and the third bus through bridges. Upon solicitation to provide its contribution to a timeout for a request subaction, the first bridge portal adds to the timeout contribution the first bridge portal's maximum request subaction processing time and either the link's maximum transmission time of half of the link's maximum transmission time, depending on the location of the destination node of the request subaction.

The invention concerns a communication method in a home network comprising at least two devices connected to a communication bus, characterized in that, a first device including an internet application and a second device including means for connecting to the internet, said second device being able to manage at least one internet application protocol, said method comprises the steps of: sending a request from said first device to said second device for opening a connection between said first and second devices, wherein said request contains an internet application protocol identifier to identify the internet application protocol to be used over said connection; sending an internet protocol request under the format of said internet application protocol from said first device to said second device; forwarding said internet protocol request from said second device to an internet server; upon receipt; transferring a response from said internet server to said first device through said second device over said communication bus. The invention also concerns a network and a device for implementing the method above.

Method for isochronous data packet transport over a wireless network, comprising the steps of: collecting a plurality of isochronous data packets at a service specific convergence sub-layer of a wireless source device; posting said plurality of isochronous data packets as a whole to a common part convergence sub-layer of the wireless source device, wherein said plurality of isochronous data packets posted to the common part convergence sub-layer corresponds to the amount of isochronous data packets generated by a transmitter over a 2 ms period.
摘要:
The invention relates to a process for managing resources in a communication network comprising at least two communication buses linked by way of a wireless transmission bridge, the said bridge comprising for each bus a real portal connected to this bus, each portal being furnished with wireless communication means. The process is characterized by the steps: modelling the said wireless bridge by each real portal in the form of virtual buses and virtual bridges, each virtual bridge comprising two virtual portals; emulating a global register of passband availability for the entire wireless bridge; reserving passband with the said global register for each wireless link participating in a communication. The invention applies in particular in field of home automation.
摘要:
Device for connecting a wireless network to at least one other network comprising a bridge module for managing a plurality of ports for connecting to respective networks, the device comprising a wireless network management module for managing associations, with an access point of a centralized wireless network, of devices of networks connected to the bridge device other than the wireless network; wherein the bridge device is adapted to be a station of the wireless network.
摘要:
A process for synchronization in a communications network comprising at least two buses interconnected by a wireless communications network, each bus being linked to the wireless communications network by a portal. The process comprises the steps of: determining a so-called cycle server portal whose own clock will serve as a reference for the other portals; transmitting, via each portal, a synchronization signal at a predetermined instant with respect to the start of a frame and characteristic of each portal, the frame being defined with respect to each portal's own internal clock, the synchronization signal being achieved via the insertion of a control window; and detecting, via each portal, the control windows of other portals and selecting one of the detected windows for the synchronization of the receiver portal's own clock with the clock of the cycle server portal, the selected window corresponding to a portal whose clock is already synchronized with that of the cycle server portal. The invention also relates to receiver and transmitter apparatuses implementing the process.

The present invention generally relates to distributed data storage systems. In particular, the present invention relates to a method of data placement in a distributed data storage system that combines high data availability with a low impact on network and data storage resources, in terms of bandwidth needed for exchange of data between network nodes and in terms of number of network nodes needed to store an item of data.
摘要:
Within the framework of a wireless local area network, the reliability of the transporting of the multicast streams is not enhanced by an acknowledgement of receipt mechanism. To improve this reliability the invention proposes a method of transporting packets transmitted in multicast mode by a device for connection between a first network and a second network, the multicast packets originating from the second network destined for clients of the first network, characterized in that it comprises a step of reception of multicast packets and the despatching according to a unicast transmission mode of at least certain packets transmitted in multicast mode to at least one of the clients of the first network that are subscribers to the transmission group.
摘要:
Method for linking a first and a second communication bus through a wireless link, comprising a first portal connected to the first bus and a second portal connected to the second bus, said first and second portal communicating over a wireless connection. The method comprises the steps of: associating the two portals to the wireless network; exchanging, between the two portals of self identification packets of nodes connected to their respective local busses, including the self identification packets of the portals themselves; generating a reset on each bus; carrying out a self identification procedure on each bus, where each portal generates self identification packets for itself and for nodes of the respective remote bus, using the self identification packets received following the association step.
