    Abstract: In one embodiment, a device in a network receives node information regarding a plurality of nodes that are to join the network. The device determines network formation parameters based on the received node information. The network formation parameters are indicative of a network join schedule and join location for a particular node from the plurality of nodes. The device generates, according to the network join schedule, a join invitation for the particular node based on the network formation parameters. The join invitation allows the particular node to attempt joining the network at the join location via a specified access point. The device causes the sending of one or more beacons via the network that include the join invitation to the particular node. The particular node attempts to join the network via the specified access point based on the one or more beacons.

    Abstract: Methods and network devices are disclosed for traffic-engineered forwarding through a new form of bit indexed explicit replication. In one embodiment, a method includes receiving at a first node in a network a message comprising a message bit array, and comparing bit values at one or more bit positions in the message bit array to one or more entries in a forwarding table stored at the first node. The one or more bit positions correspond in this embodiment to links in the network. This embodiment of the method further includes forwarding the message over a link represented in the forwarding table if a result of the comparing indicates that the link is included in a path to be taken by the message. In a further embodiment of the method, the message is a multicast message and forwarding the message comprises forwarding a replica of the multicast message.

    Abstract: In one embodiment, an addressing agent determines a logical static IP addressing scheme for a computer network, the addressing scheme shared with an application server and defining a static mapping of IP addresses to particular types of application-based devices that are managed by the application server in particular physical locations within the computer network. The addressing agent determines a topology of the computer network indicative of application-based devices, their type, and their physical location. The addressing agent calculates a dynamic IP address for the devices based on their type and physical location as defined by the addressing scheme, and collaboratively assigns their corresponding calculated dynamic IP address. The application server can thus manage application-based devices according to whichever device of a particular type is in a particular physical location based on the addressing scheme, regardless of which particular application-based device of that particular type is in that particular physical location.

    Abstract: Methods and network devices are disclosed for failure protection in traffic-engineered bit indexed explicit replication networks. In one embodiment, a method includes receiving at a node in a network a message comprising a message bit array, where bit positions in the message bit array correspond to respective links in the network. The method further includes evaluating a bit value at a bit position in the message bit array, where the bit position corresponds to a network link represented in a forwarding table for the node, checking for a failure state of the link represented in the forwarding table, and, responsive to a determination of a failure state of the link, modifying one or more bit values in the message bit array. In one embodiment a network device includes a network interface, a memory configured to store a forwarding table, and a processor configured to carry out the methods.
