摘要： A method and apparatus for routing packets in a network, such as a satellite mesh network. Geographic routing is employed in which packets specify their physical destination location. Network nodes maintain physical location information for nodes, along with routing information, for a limited portion of the network which is local thereto. At each node and for each packet, a target node is selected from the limited portion. The target node may be the node which is closest in orthodromic distance to the physical destination location. Based on the routing information, a next node belonging to the limited portion of the network and located along an available network path between the node and the target node is determined, and the packet is forwarded to the next node.

摘要： In a configuration wherein N individual fibers interconnect two devices, each fiber can be configured, through configuration of the packet processing devices at each end of the fiber, to carry traffic in a single direction. From the perspective of the first device, an arbitrary subset T of the N fibers can be used for transmitting signals to the second device. The packet processing devices terminating a subset R of the remaining N-T fibers can be configured so that the first device may receive signals from the second device.

摘要： A front-haul controller for a network coupling a BBU and an RRH that exchanges RF analog signals with a supported UE. The network comprises a plurality of nodes coupled by variable bit-rate network communications links. The BBU exchanges packets of frequency-domain samples with the RRH along the network. The front-haul controller monitors information about wireless spectrum occupancy at the RRH and at least one spectrum occupancy threshold and varies a bit-rate of the network link in accordance therewith. The front-haul controller can proactively adjust the bit-rate and/or the threshold during periods associated with at least one event that may impact the spectrum occupancy. The network link can be a FlexE, SONET, DWDM, LAG and/or ECMP link.

摘要： A ring control protocol is used to establish a separate control plane for a plurality of physically dual homed devices to enable collections of dual homed devices to be represented by a single pair of addresses into the attached routed Ethernet network. The gateway devices analyze the passing ring control packets to create direct mappings for data packets to the routed Ethernet network. Thus, although the dual homed devices are treated as a ring from a control perspective, the data path is implemented to be direct so that data packets continue to flow directly from the dual homed devices to each of the attached gateway devices. In one embodiment, each of the gateway devices implements a virtual switch and advertises the MAC address of the virtual switch into the routed Ethernet network rather than the MAC addresses of each of the attached Ethernet Switch Units.

摘要： In at least some embodiments, the disclosure includes an apparatus a root node in a packet based network that multicasts a plurality of packets. The apparatus also includes an intermediary node coupled to the root node and a plurality of leaf nodes coupled to the intermediary node. The root node, the intermediary node, and the plurality of leaf nodes are arranged in a tree topology. The packets are received at the intermediary node from the root node at a data rate equal to the data rate of the leaf node having the maximum data rate. The packets are multicast from the intermediary node to each of the plurality of leaf nodes at a plurality of different data rates such that each particular one of the plurality of leaf nodes receives the packets at a data rate corresponding to the data rate for the particular one of the plurality of leaf nodes.

摘要： A method and apparatus in provided which enables fast layer 2 reconfiguration in a network that includes Routing Bridges. Each Routing Bridge stores, for each forwarding target, identifiers of a primary next Rbridge and an alternate next Rbridge. The forwarding target may be a network end node, or an Egress Rbridge associated with the network end node. In response to a trigger condition, layer 2 communications are selectively switched from a path that includes the primary next Rbridge device to a path that includes the alternate next Rbridge device.

摘要： Paths may be advertised on a network implementing a link state routing protocol by using Path State Advertisements (PSAs) that are distributed in the same manner as link state advertisements. The path state advertisements contain path entries, each of which includes a globally unique path ID and path information such as a series of nodes or links that defines the path through the network. When a PSA is received by a network element, the network element will evaluate the path entries in the PSA to determine if the PSA is relevant and, if necessary, install forwarding state for the relevant path entries. PSAS not relevant to a network element are not used to affect forwarding state on the network element. Label based forwarding may be used by the network elements to forward data along the path, in which the globally unique path ID is used as the label.

摘要： A packet header in a source routed network is augmented to include, with each hop identifier, at least one bit for indicating congestion at the particular hop. As the packet traverses from the source to the destination, when congestion is detected at a hop, a congestion bit associated with the hop is set in the header. At the destination, when another packet is forwarded from the destination to the source on the same path, the congestion bits are reflected back to the source. When the source receives the congestion bits, it has the option of re-routing subsequent communications between the source and destination nodes by generating a new hop list, which routes around one or more of the congested hops.
