摘要： A method and apparatus for routing multiple data streams simultaneously through independent routes between multiple-input-multiple-output (MIMO) stations in a mesh network. The disclosed feature allows transmission of multiple data streams via multiple routes from a source station (STA) to a destination station (STA), which are both MIMO capable, even though the relay STAs in between can be a single-input-single-output (SISO) STA. An extended routing request (RREQ) and routing reply (RREP) frames are utilized which provide a primary and secondary flag indication, which is utilized in combination with advanced programming for setting path cost metrics to assure independence of primary and secondary routes.

摘要： A system and method of managing a network that includes assets are described. The method includes modeling the network as a directed graph with each of the assets represented as a node and determining alternative paths to each node from each available corresponding source of the node. The method also includes computing upstream robustness of each node, computing upstream robustness of the network, and computing downstream criticality of each node. Managing the network and each asset of the network is based on the upstream robustness and the downstream criticality of each node.

摘要： Disclosed herein are systems, methods, and computer readable media for modifying IP backbone link weights such that multicast traffic and unicast traffic will not travel on a same path between nodes. The method comprises assigning link weights to nodes within an IP backbone such that multicast forwarding paths and unicast forwarding paths are failure disjoint, and delivering undelivered multicast packets using IP unicast encapsulation to the loopback address of next hop router on a multicast tree upon link/interface failure.

摘要： A method and system are described for providing hitless protection in a packet switched network having source nodes and destination nodes. The method includes enabling a working path and a protecting path between the source and destination nodes. The working path is non-overlapping with respect to the protecting path. The method further includes replicating traffic in a given one of the source nodes to generate replicated traffic. The method also includes forwarding the traffic and the replicated traffic through a working path and a protecting path, respectively, from the given one of the source nodes to a particular one of the destination nodes. The method additionally includes delivering a hitless-protected service in the particular one of the destination nodes by selecting traffic packets received from either the working path or the protecting path.

摘要： Each of a network fabric controller device and a network fabric forwarder devices includes network connecting hardware and network managing logic. The network connecting hardware of the devices connects them to a singly contiguous network fabric including switching devices that route data between initiator nodes and target nodes and that have routing logic programmable by the controller device. The controller device does not directly route the data themselves. The network managing logic of the devices effects multipaths for transmission of the data through the singly contiguous network fabric from the initiator node to the target nodes via programming of the routing logic of the switching devices.

摘要： A method for establishing disjoint data connections between two clients by a network is proposed. The method comprises different steps at different devices. A first client device sends via a client-network interface one or more connection request messages to a network for requesting at least two disjoint data connections to a second client device. The one or more connection request messages contain first indicating data, indicating a first predetermined set of network resources, and second indicating data, indicating a second predetermined set of network resources, which is disjoint to said first set of network resources.
