Conveying network-address-translation (NAT) rules in a network
In one embodiment, a first networking device associated with a switched network comprises one or more processors and one or more computer-readable media storing computer-executable instructions that, when executed, cause the one or more processors to perform acts comprising configuring, on the first networking device, a network-address-translation (NAT) rule indicating that a first multicast group is to be translated to a second multicast group. The acts further include, at least partly in response to the configuring of the NAT rule, storing the NAT rule at the first networking device, generating a message indicating the NAT rule, and sending the message to at least a second networking device associated with the switched network.
Cellular access of user-defined networks
Techniques are described herein for providing cellular access of a user-defined network. In one example, a user plane function of a cellular network obtains, from a control plane function of the cellular network, an indication that a first user equipment is attempting to connect to a user-defined network via the cellular network. The user plane function joins a multicast group configured to include a second user equipment connected to the user-defined network via a wireless local area network. The user plane function obtains a multicast packet that is transmitted between the first user equipment and the second user equipment and that is addressed to the multicast group, and converts the multicast packet to a unicast packet.
Localized multicast in a low power and lossy network based on rank-based distance
In one embodiment, a method comprises: identifying, by a low power and lossy network (LLN) device in a low power and lossy network, a minimum distance value and a distance limit value for limiting multicast propagation, initiated at the LLN device, of a multicast data message in the LLN; and multicast transmitting, by the LLN device, the multicast data message with a current distance field specifying the minimum distance value and a distance limit field specifying the distance limit value, the multicast transmitting causing a receiving LLN device having a corresponding rank in the LLN to respond to the multicast data message by: (1) determining an updated distance based on adding to the current distance field a rank difference between the receiving LLN device and the LLN device, and (2) selectively retransmitting the multicast data message if the updated distance is less than the distance limit value.
Public access point
The invention instantiates a Personal VLAN bridge, using IEEE Std. 802.11 elements. The result is a bridge, referred to as a public access point, that is better suited for implementing public wireless data networks than the IEEE Std. 802.11 architecture. The invention also provides a location-update protocol for updating the forwarding tables of bridges that connect public access points together. The invention further provides a method for more controlled bridging, which is referred to as fine bridging.
Method of concerted data synchronisation across a wireless mesh network
A method for concerted synchronization of data across a wireless mesh network comprises transmission of a broadcast message to a target device via a predicted route that is capable of being acknowledged by at least one network device not on the predicted route. The data is assimilated from at least one network device, and is capable of addition to a broadcast message. In this way, it is possible to synchronize a plurality of network devices via one outgoing broadcast message and one incoming broadcast message.
REDUNDANT TRAFFIC SUPPRESSION RELAYING MECHANISM FOR BLE-MESH SYSTEMS
A BLE-Mesh device includes a controller, an RF driver for driving the transceiver adapted to be coupled to an antenna, and a counter. The controller implements an applications layer including BLE and Mesh Applications, and a BLE stack and a mesh stack. A redundant traffic suppression relaying algorithm is for waiting for a random time within a selected time window from W1 to a later W2 before attempting to transmit a first packet that has the first relay device's sender's source (SRC) address and a sequence (SEQ) number. If during the random time a packet with both the device's SRC address and the SEQ number is received, the counter is incremented from an initial count to a current count. After the random time elapses, the current count is compared to a Cthreshold value, and the first packet is transmitted only if the current count <the Cthreshold value.
Device, system and method for transmitting a response command to a radio using a visualization of locations of radios and communication links therebetween
A device, system and method for transmitting a response command to a radio using a visualization of locations of radios and communication links therebetween is provided. A device generates a visualization of respective locations of radios and communication links therebetween, the visualization distinguishing between the radios that are inside a coverage area of a communication network and a first radio that is outside of the coverage area, the visualization indicating a second radio in communication with the first radio via a local communication link. The device detects an input indicating a response command associated with the first radio. The device determines a routing path from the computing device to a given radio of the radios that are inside the coverage area. The device transmits, to the given radio, via the routing path, the response command.
CONVEYING NETWORK-ADDRESS-TRANSLATION (NAT) RULES IN A NETWORK
In one embodiment, a first networking device associated with a switched network comprises one or more processors and one or more computer-readable media storing computer-executable instructions that, when executed, cause the one or more processors to perform acts comprising configuring, on the first networking device, a network-address-translation (NAT) rule indicating that a first multicast group is to be translated to a second multicast group. The acts further include, at least partly in response to the configuring of the NAT rule, storing the NAT rule at the first networking device, generating a message indicating the NAT rule, and sending the message to at least a second networking device associated with the switched network.
Systems and methods to support node mobility in wireless networks
A network includes a mobile network node (MNN) that includes a mobile node communications manager (MNCM) to facilitate wireless communications to a plurality of stationary network nodes (SNNs) in a wireless network via a wireless network protocol. The MNCM utilizes a multicast address received over the wireless network. The multicast address is assigned to a predetermined network time slot to communicate uplink data from the MNN to the SNNs. The MNN receives downlink data via a separate predetermined network address and time slot assigned to a given SNN.
ORTHODROMIC ROUTING
A method and apparatus for routing packets in a network, such as a satellite mesh network. Geographic routing is employed in which packets specify their physical destination location. Network nodes maintain physical location information for nodes, along with routing information, for a limited portion of the network which is local thereto. At each node and for each packet, a target node is selected from the limited portion. The target node may be the node which is closest in orthodromic distance to the physical destination location. Based on the routing information, a next node belonging to the limited portion of the network and located along an available network path between the node and the target node is determined, and the packet is forwarded to the next node.
