Abstract:
The disclosed embodiments provide a system for transmitting a link state message in a network. During operation, the system obtains a network topology for the network. Next, the system uses the network topology to identify a reflood set of neighbors of the flooding node for reaching a set of two-hop neighbors of the flooding node. The system then transmits a link state message with an indication to reflood the link state message to the reflood set of neighbors. Finally, the system transmits the link state message without the indication to reflood to remaining neighbors of the flooding node that form a non-reflood set.
Abstract:
A method is implemented by a network device that functions as a border node of a first area and a second area of a multi-area hierarchical computed source packet in routing (SPRING) network, where sources for multicast groups with sources in a second area are represented as virtual nodes in a first area, where the first area is a level 1 (L1) network and the second area is a level 2 (L2) network. The method supports the interworking of areas in the hierarchical computed SPRING network.
Abstract:
A method is executed by a network device in a network implementing multicast using unicast tunnels. The network device functions as a computing element for convergence after an event potentially affecting a multicast distribution tree (MDT) in the network. The method maximizes reliability and minimizes an impact of a re-optimization of the convergence by sequencing the installation of updates to state in at least one forwarding element in the network to reduce lost data packets and delay of data packets during an update sequence. The method includes receiving at the computing element the event potentially.
Abstract:
Systems and methods for supporting SMP connectivity checks across virtual router in a high performance computing environment. In accordance with an embodiment, SMA model enhancements allow for the possibility to send a packet (i.e., SMP) that is addressed to a local router port. The SMA where the packet is addressed can receive the packet, and then apply a new attribute that defines that the requested information is on a remote node (e.g., connected by a physical link across subnets). In accordance with an embodiment, the SMA can operate as a proxy (receives a SMP and sends another request), or the SMA can modify the original packet and send it on as an inter-subnet packet.
Abstract:
Systems, methods, and apparatuses are provided herein for time-stamping a Controller Area Network ("CAN") bus message. Control circuitry (e.g., of a network bridge) may receive a CAN message, and may, in response to receiving the CAN message, generate a time stamp. The control circuitry may add an entry to a lookup table stored in memory, wherein the entry correlates a CAN message Identifier ("ID") corresponding to the CAN message with the time stamp. The control circuitry may encapsulate the CAN message and the time stamp, and may transmit the CAN message according to the time stamp.
Abstract:
A method includes receiving one or more node connections (310) from a mesh network (200) external to the data processing hardware. The mesh network includes a network of nodes (350) each operative to transmit and/or receive directional beams containing packets of data (80). The method also includes identifying a route (201, 202) within the mesh network for providing a data packet from a source (210) to a destination (220) and determining schedule information (34) associated with the identified route, the schedule information coordinating wireless communication between at least a first node and a second node along the route to transfer the data packet. The method also includes providing the schedule information to the first node and the second node.
Abstract:
A method for providing a service by a transparent internet cache (TIC) server in a communication network supporting a multipath transport control protocol (MPTCP) is provided. The method includes establishing an MPTCP connection with a user equipment (UE) and an original server through a first network, upon receiving a service provision request from the UE, releasing the MPTCP connection established among the TIC server, the UE, and the original server if data related to a service corresponding to the service provision request is cached, and providing the service corresponding to the service provision request to the UE.
