摘要:
The invention relates to a method of transmitting data over a wireless link, comprising the insertion of the data into packets according to a format corresponding to at least certain layers of a first protocol for data transmission over a wireless network, as well as the use of these packets to form a frame in accordance with a second protocol for data transmission over a wireless network, different from the first protocol, and the transmission over the wireless network according to the second protocol. The invention also relates to the apparatus implementing the method.
摘要:
A method for connecting a device to a wireless network; at the level of a bridge device, configure to interface with the wireless network that maintains single management information. The bridge device separately registers, with respective MAC addresses, the device and itself as wireless devices on the wireless network.
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 method for reserving an isochronous resource over a link between a first bus and a second bus, the link including a first interface device connected to the first bus and a second interface device connected to the second bus. The reservation of the resources over the link is transparent to the devices connected to the busses. The method includes, at the level of the interface devices, intercepting the connection set up messages sent by the devices connected to the busses, checking whether a source device and a sink device for which the set-up message has been intercepted are on different busses, and in the affirmative, reserving resources for the connection over the link.
摘要:
An electronic device with a limited time of use. The electronic device comprises a physical interface for removable connection to a host device, a processor and a usage time limit module with a counter. When the counter reaches a pre-determined value, the usage time limit module is configured to disable the electronic device, preferably by modifying the hardware of the electronic device, e.g. by disabling a communication line between the processor and the physical interface, which may be effected by blowing a fuse. The usage time limit module is powered by the host device via a power supply from the physical interface. In a preferred embodiment, the electronic device is a storage device. In a further preferred embodiment, the physical interface is a USB interface.
摘要:
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:
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.
摘要:
The invention concerns a method for transmitting packets in a network comprising at least a first sub-network and a second sub-network connected through a transparent communication link, said link comprising at least a first interface device connected to the first sub-network and a second interface device connected to the second sub-network. The method comprises the steps of: attributing a first set of addresses to the interface devices on the communication link; attributing a second set of addresses to nodes connected to the sub-networks, the attribution of the second set being done independently from the attribution of the first set; checking whether there appears a conflict between an address of the first set and an address of the second set, and in the affirmative: changing the conflicting address of the first set to a non conflicting address. The invention also concerns a device for implementing the method as well as a method for detecting and transmitting packets to be transmitted over the link.
摘要:
The invention concerns a method for managing resets in a communication network comprising wireless devices connecting busses over a wireless link, comprising the steps of: electing a parent wireless device among the wireless devices of the network, other wireless devices being labeled child wireless devices; having a first child wireless device send a bus reset message to the parent wireless device further to a reset on the child wireless device's local bus; having the parent wireless device spread the bus reset to other child wireless devices; having the other child wireless devices perform a bus reset on their local wired bus.
摘要:
A method and device for implementing a method for associating communication devices capable of wireless interfacing. The method includes producing a relation between communication devices capable of wireless interfacing enabling dialogue among them exclusively. The devices comprise a single and permanent identifier, can be connected to a cable network and exchange data through the latter. The association can be modified by connecting the devices to be associated to a single cable network.
