Abstract: In some embodiments, a device in a network receives a packet from a sender that is destined for a receiver. The device forms duplicate packets of the packet. The device assigns a sequence number to the duplicate packets based on an identity of the sender and on a flow identifier associated with the packet. The device sends the duplicate packets with the sequence number via different paths in the network towards the receiver.

Abstract: In one embodiment, a device in a wireless network selects a transmission rate for one or more packets to be sent, based on a received signal strength indicator value. The device makes a determination that the one or more packets should be compressed, based on the transmission rate selected by the device. The device applies, based on the determination, stateless offline dictionary compression to the one or more packets, to form a compressed stream of one or more packets. The device sends the compressed stream via the wireless network and using the transmission rate selected by the device.

Abstract: In one embodiment, a mobile node having a first radio and a second radio applies stateless offline dictionary compression to an uncompressed stream of packets, to form a compressed stream of packets. The first radio of the mobile node communicates with a first access point of a wireless network and the second radio of the mobile node communicates with a second access point of the wireless network. The mobile node selects the first radio to send the uncompressed stream of packets and the second radio to send the compressed stream of packets. The mobile node sends, via the first radio, the uncompressed stream of packets to the first access point over a first wireless path. The mobile node sends, via the second radio, the compressed stream of packets to the second access point over a second wireless path.

Abstract: In one embodiment, a device identifies a plurality of access points of a wireless network. The device also identifies a plurality of mobile nodes of a mobile system. The device establishes a first label-switched path in the wireless network that comprises a wireless link between a first mobile node in the plurality of mobile nodes and a first access point in the plurality of access points. The device establishes a second label-switched path in the wireless network that comprises a wireless link between a second mobile node of the mobile system and a second access point in the plurality of access points.

Abstract: In one embodiment, a controller predicts an occurrence of an event in a wireless network, based in part on a movement of a mobile node of the wireless network. The controller initiates application of network-layer forward error correction encoding to a stream of packets to be sent during the event between the mobile node and an access point of the wireless network, to form one or more encoded packets. The controller causes the one or more encoded packets to be transmitted in conjunction with the stream of packets during the event. The controller ceases application of the network-layer forward error correction encoding after the event has occurred.

Abstract: In one embodiment, a controller obtains a stream of data packets. The controller applies network-layer forward error correction encoding to the stream of data packets, to form one or more encoded packets. The controller causes the stream of data packets to be sent via a link in a wireless network between a first radio of a node in the wireless network and a first access point to which the first radio is wirelessly connected. The controller causes the one or more encoded packets to be sent between a second radio of the node and a second access point in the wireless network.

Abstract: In one embodiment, a client device having a plurality of radios obtains a list of basic service set identifiers (BSSIDs) for a plurality of wireless access points of a wireless network. The client device associates each of the plurality of radios of the client device with a different wireless access point of the wireless network, based on the obtained list of BSSIDs. The client device receives a copy of a data packet from a particular one of the associated wireless access points. Each of the associated wireless access points receives a replicated copy of the data packet to be transmitted towards the client device. The device causes the associated wireless access points to cease further transmission of their copies of the data packet by acknowledging receipt of the data packet to the particular wireless access point.

Abstract: A communication system (100) and method for coupling a wireless local area network (WLAN 128) to a public network (102) to enable communication between User Equipment terminals (UEs 130) associated with the WLAN and the public network. The public network (102) can include a GSM (110) and/or a 3G-network (114). The WLAN (128) can include a HiperLAN, HiperMAN, or 802.11 network. Preferably, the communication is voice communication, and the system (100) is configured to enable the UEs (130) to access supplementary services provided by the public network (102). Subscriber and security information for the UEs (102) can be provided to the public network (102) from a SIM (134) associated with each UE, or from an identity module (138) comprising either a private memory with information stored therein, or a card holder/reader holding cards with subscriber and security information for one or more UEs.
