摘要： Systems and methods may be provided embodying an optimized Trill LAN network hello mode. The optimized hello mode may allow the number of LAN hellos exchanged to be reduced significantly in a steady state mode of operation. No modifications to the current Trill specification are needed and in a converged state (when designated RBridge election and appointed forwarder appointments are complete), only 1 hello PDU per RBridge is originated in every hello interval.

摘要： The method involves issuing, by an active interface, an Internet Protocol probe packet (IPPP) to a probe target, issuing, by a first alternate interface, a first transitive probe packet (TPP) to the active interface, where the first alternate interface and the active interface belong to a broadcast domain. The method further involves awaiting, by the active interface, a responsive IPPP from the probe target, awaiting, by the first alternate interface, a first responsive TPP from the active interface, and determining network conditions based upon receiving at least one of the responsive IPPP and the first responsive TPP.

摘要： The invention relates to a method for routing packets. The method includes receiving a first packet to route, obtaining a first route entry using a first IP address associated with the first packet, where the first route entry includes a first prefix, a first route nexthop generation (RNG) and a first route nexthop pointer (RNP) to a second route entry. The method further includes comparing a route generation (RG) for the second route entry with the first RNG where the RG for the second route entry and the first RNG are equal, obtaining a first neighbor cache entry (NCE) from a first NCE pointer (NP) stored in the first route entry, and routing the first packet using the ARP information in the first NCE, where a route dependency list pointer (RDLP) in the second route entry points to the first route entry.

摘要： In a particular embodiment of the present invention, a forwarding node in an ad hoc network collects sets of node information pertaining to its neighbor nodes. An example of a type of node information is history information that indicates previous time periods during which a neighbor node has been available for communication. Other types of node information may include proximity information that indicates how far a neighbor node is from the forwarding node. In selecting a routing path, the forwarding node takes into account information collected in the sets of node information. A routing path can be selected to include a neighbor node having the highest probability to be available for communication. Additionally or alternatively, a routing path may be selected to minimize the power transmission level required for the forwarding node to forward data packets.
