摘要： One embodiment allocates and uses exclusive and overlapping transmission units in a network. One embodiment includes sending information, from a first network node in a network, during an exclusive transmission unit, wherein the exclusive transmission unit includes one or more wireless time slot-frequency pairings assigned to the first network node to send info nation without another assigned network transmission unit providing overlapping time slot-frequency interference from another network node communicating in the network. One embodiment includes sending information, from the first network node, during an overlapping transmission unit, wherein the overlapping transmission unit includes one or more wireless time slot-frequency pairings assigned to the first network node to send information, with the overlapping transmission unit overlapping in time slot-frequency with one or more other assigned network transmission units that will cause interference if simultaneously used.

摘要： A node in a Low power and Lossy Network (LLN) is managed by monitoring a routing configuration on a node in a LLN. A triggering parameter that is used to invoke an address change on a child node is tracked and a threshold against which to compare the triggering parameter is accessed. The triggering parameter is compared to the threshold. Based on results of comparing the triggering parameter to the threshold, it is determined that an address change at the child node is appropriate. An address change of a child node appearing in the routing configuration is invoked based on the determination that an address change is appropriate.

摘要： In one embodiment, a node “N” within a computer network utilizing directed acyclic graph (DAG) routing selects a parent node “P” within the DAG, and, where P is not a DAG root, may determine a grandparent node “GP” as a parent node to the parent node P. The node N may then also select an alternate parent node “P′” that has connectivity to GP and N. N may then inform P and P′ about prefixes reachable via N, and also about P′ as an alternate parent node to P to reach the prefixes reachable via N. Also, in one embodiment, P may be configured to inform GP about the prefixes reachable via N and also about P′ as an alternate parent node to P to reach the prefixes reachable via N, and P′ may be configured to store the prefixes reachable via N without informing other nodes about those prefixes.

摘要： A system for providing a tree topology for a network having an interior gateway protocol. A first router receives a hello message from all connected routers in the network. The hello messages include tree topology information. The first router then uses the tree topology information to determine a parent of the router. The first router then establishes connections with directly connected routers at the same level in the tree topology. The first router also generates link messages that include all of the prefixes for children of the first router and broadcasts the link messages.

摘要： A clusterhead of a tree-based, mobile ad hoc network includes a mobile IP proxy resource for registering a received binding update request from a mobile ad hoc router within the network, creating a first mobile IP tunnel with the mobile ad hoc router, sending a second binding update request to a remote home agent of the mobile ad hoc router, and initiating a second mobile IP tunnel between the clusterhead and the home agent. If a packet received from the mobile ad hoc router specifies a destination determined as reachable within the mobile ad hoc network, use of the second mobile IP tunnel is minimized by outputting the packet toward the destination according to the mobile ad hoc routing protocol. If the packet is not reachable within the mobile ad hoc network, the packet is forwarded via the second mobile IP tunnel to ensure packet transmission is topologically correct.

摘要： A mobile router is configured for attaching to a selected router in a clustered network (e.g., a mobile ad hoc network) based on identifying a network topology model of the clustered network from received router advertisement messages that include tree information option fields specifying attributes of the network topology model. The mobile router selects which router advertisement originator to attach to based on correlating the attributes of the router advertisement originators relative to identified priorities, and orders the router advertisement originators within a default router list based on the identified priorities. If the mobile router detects a router from a second clustered network, the mobile router advertises to the attachment router that the second clustered network is reachable, enabling the two clustered networks to communicate using a point-to-point link between the respective attachment routers.

摘要： A default gateway router of a multi-homed site is configured for supplying, to a host device, a plurality of address prefixes having been advertised by respective exit routers providing respective connecting links for the multi-homed site to a wide area network. The default gateway router sends the address prefixes to the host device in a determined order based on a determined preference in the default gateway router for reaching the respective exit routers. The host device is configured for selecting a source address according to the determined order supplied by the default gateway router. The address also prefixes may be grouped according to identified destination prefixes, enabling the host device to select, for a given identified destination prefix, the source address according to the ordering of address prefixes within the corresponding group.

摘要： A source IPv6 mobile node is configured for forwarding an IPv6 packet via an IPv4 connection with a destination IPv6 router. The IPv4 packet includes IPv4 source and destination addresses, a UDP source port and UDP destination port, and a synthetic tag address in the IPv6 destination address field. The synthetic tag address, a valid (routable) IPv6 care of address, has an address prefix routed to the IPv6 router. The address prefix specifies a forwarding protocol, the IPv4 destination address for the IPv6 router, and a site-level aggregation identifier. An address suffix for the synthetic tag address specifies the IPv4 source address, the UDP source port and UDP destination port. Hence, the synthetic tag address enables the destination IPv6 router to send an IPv6 reply packet back to the source IPv6 mobile node via the IPv4 network.
摘要翻译：源IPv6移动节点被配置为经由与目的地IPv6路由器的IPv4连接来转发IPv6分组。 IPv4分组包括IPv4源地址和目的地址，UDP源端口和UDP目的端口，以及IPv6目的地址字段中的合成标签地址。合成标签地址，一个有效的（可路由的）IPv6地址保护，具有路由到IPv6路由器的地址前缀。地址前缀指定转发协议，IPv6路由器的IPv4目的地址和站点级聚合标识符。合成标签地址的地址后缀指定IPv4源地址，UDP源端口和UDP目的端口。因此，合成标签地址使目的IPv6路由器能够通过IPv4网络将IPv6应答分组发送回源IPv6移动节点。
