Abstract: In one embodiment, an intermediate node in a contention-based shared-media computer network determines a scheduled window within which a packet (with an assigned priority) should be transmitted by the intermediate node. In particular, the intermediate node may specifically determine whether an actual transmission time is prior to, during, or after the window, and sets a priority of the packet as either i) a reduced priority when the actual transmission time is prior to the window, ii) the assigned priority when the actual transmission time is during the window, or iii) an augmented priority when the actual transmission time is after the window. As such, the intermediate node may then transmit the packet from the intermediate node with the set priority at the actual transmission time.

Abstract: In one embodiment, an intermediate node of a computer network can receive a message intended for a destination. The message can include a header indicating a source route. The intermediate node can determine a routing entry for the destination associated with a next hop based on the source route and cache the routing entry. The intermediate node can further receive a second message intended for the destination that does not indicate the next hop, and transmit the second message according to the cached routing entry.

Abstract: In one embodiment, a particular device (e.g., switch) receives a neighbor discovery (ND) message from a non-trusted non- switch device, the ND message having an associated address, and creates a corresponding binding entry for the address in a temporary tentative state without forwarding the ND message. In addition, the switch then generates and forwards a first duplicate address detection (DAD) message on behalf of the non-trusted non-switch device. In response to receiving a second DAD message from a non-owner device, the switch may either drop the second DAD message when a corresponding second address of the second DAD message is stored as a tentative-state entry, or else forward the second DAD message to a corresponding owner device of the second address for neighbor advertisement (NA) defense when the second address is not stored as a tentative-state entry.

Abstract: A source IPv6 mobile router is configured for establishing an IPv4 tunnel with destination IPv6 mobile router using a synthetic tag address, specifying a forwarding protocol, and IPv4 source and destination addresses. If an optional transport header is used (e.g, UDP port), the source port and destination port also are added to the synthetic tag address. The IPv6 packet includes a reverse routing header that enables the destination IPv6 mobile router to recover routing information for reaching the source IPv6 mobile router via the IPv4 network. Hence, all IPv4 routing information that may be needed by the destination IPv6 mobile router in sending an IPv6 reply packet back to the source IPv6 mobile router is maintained in the routing header specified in the IPv6 reply packet.

Abstract: A mobile router is configured for optimized utilization of reverse routing headers, to specify a path between an originating mobile router and a home agent. Reverse routing headers enable each mobile router within the path to the home agent to specify its care of address, enabling the home agent to establish a bidirectional tunnel to the originating mobile router via the corresponding mobile router. The mobile router selectively updates the reverse routing header in a received packet by inserting the source address value of the received packet into the reverse routing header and inserting its corresponding care of address into the specifies reachability of a most recent entry in the reverse routing header via the source address value. The mobile router also may request the originating mobile router to increase the reverse header size.

Abstract: Methods and apparatus for processing registration requests by a Home Agent supporting Mobile IP are disclosed. A registration request is received from each of a plurality of Mobile Nodes, the registration request specifying a care-of address. A binding is established between each of the plurality of Mobile Nodes and the associated care-of address, each of the plurality of Mobile Nodes being associated with one another. For instance, the plurality of Mobile Nodes may be statically or dynamically assigned the same Home Address. A tunnel is then created between the Home Agent and the care-of address for each of the plurality of Mobile Nodes, thereby enabling a server request to be distributed by the Home Agent to one of the plurality of Mobile Nodes via the associated tunnel. For instance, a server request addressed to the Home Address may be forwarded to one of the Mobile Nodes assigned that Home Address.
