摘要： Latency Based Forwarding (LBF) techniques are presented for the management of the latencies, or delays, of packets forwarded over nodes, such as routers, of a network. In addition to a network header indicating a destination node for receiving the packet, a packet also includes an LBF header indicating the packets accumulated delay since leaving the sender and maximum and minimum latencies for the entire journey from the sender to the receiver. When a packet is received at a node, based on the accumulated delay, the maximum latency, and the minimum latency, the node places the packet in a forwarding queue to manage the delays between the sender and the receiver. The LBF can also indicate a policy for the forwarding node to used when determining the enqueueing of the packet. A dynamic queueing policy can increase the fairness with which packets are forwarded.

摘要： A system for dynamically offloading data and video traffic to a broadcast offload core network from a cellular network or to the cellular network from the broadcast offload core network is provided. The system includes an analytics engine (301), a load manager (304), and a radio access network (RAN). The analytics engine (301) captures geographical radio frequency (RF) information from a geographical RF information database. The geographical RF information includes an operator infrastructure information, a physical terrain information, a subscriber information, a coverage information, a signal quality information, and telecom traffic patterns. The analytics engine (301) determines whether to offload the data and the video traffic to at least one of a unidirectional downlink network from a unicast network or the unicast network from the unidirectional downlink network by analyzing a hybrid cellular user equipment (306) from a particular geographical location trying to access the data or video content.

摘要： An illustrative embodiment includes a host device configured to communicate over a network with a storage system comprising a plurality of storage devices. The host device comprises a set of input-output queues and a multi-path input-output driver configured to select input-output operations from the set of input-output queues for delivery to the storage system over the network. The multi-path input-output driver is further configured to determine fabric identifiers for respective ones of a plurality of paths from the host device to the storage system, and to select particular ones of the paths for delivery of the input-output operations to the storage system based at least in part on the fabric identifiers. The fabric identifiers may be determined for the respective paths, for example, based at least in part on responses to a predetermined command sent over the paths by the multi-path input-output driver.

摘要： A router and methods for routing packets in a network are described. The router and methods are implemented with a dynamic link state routing protocol (DLSP). The router dynamically computes a best path from one or more paths by periodically probing links of peer nodes to determine link metrics associated with a link. The one or more link metrics include a link bandwidth to a peer node and a link latency to the peer node. Further, the router can dynamically recalculate the one or more link metrics associated with the link every 10 seconds. The router can also monitor one or more link state changes based on the one or more link metrics, wherein the link state changes are monitored every 60 second. The router can further determine a single link metric based on the link bandwidth to the peer node and the link latency to the peer node.

摘要： A system and method for determining a network path through a network that is managed by a software defined network (Ts SDN) controller incorporating time management are disclosed. In some embodiments, the SDN controller can determine that a data packet originating from a transmitting device and directed to a receiving device is associated with one of: time-sensitive, time-aware or best effort characteristic. The controller can then determine a network path for transport of the data packet from the transmitting device to the receiving device with a guaranteed end to end delay to satisfy the characteristic. The end to end delay considers latency through each layer the data packet transitions through after being conjured at an application layer of the transmitting device. The data packet is then transmitted from the transmitting device via the network path to the receiving device.

摘要： A method is performed by a network device acting as a switch in a Software Defined Networking (SDN) network, where the switch has established a plurality of connections with a controller in the SDN network. The method implements connection-specific output actions to provide control over which connection from the plurality of connections is to be used by the switch for transmitting packets to the controller. The method includes generating a flow entry that includes a packet matching criteria and an output action that specifies a connection identifier. The method further includes receiving a packet for forwarding, determining whether the packet matches the packet matching criteria of the flow entry, and transmitting the packet to the controller using the connection identified by the connection identifier specified in the flow entry in response to determining that the packet matches the packet matching criteria of the flow entry.
