摘要： Embodiments herein relate to transmitting specific traffic along a blocked link. A status of links between switches of a network is monitored. The status of the links is one of blocked and non-blocked. A blocked link is not used by a Spanning Tree Protocol (STP). At least one of the network switches is configured to transmit the specific traffic along the blocked link.

摘要： A method includes receiving, by a network management system, network data from a plurality of network devices configured to provide a network at a site; receiving, by the processing circuitry, user impact data from a plurality of client devices that access the network at the site; determining, based on the network data, a pattern of one or more network events occurring over time; correlating in time the pattern of the one or more network events to an adverse user impact event indicated by the user impact data received from the plurality of client devices; and determining, in response to the correlating, an instance of overwhelming network traffic having an adverse user impact. In some examples, the network data includes network traffic impact data, such as a number of packets dropped at a switch port due to congestion.

摘要： Methods and systems for supporting efficient load balancing among a plurality of switches and a plurality of end nodes arranged in a tree topology in a network environment. The methods and systems can sort the plurality of end nodes, wherein the plurality of end nodes are sorted in a decreasing order of a receive weight. The method and system may further route, in the decreasing order of receive weights, the plurality of end nodes, wherein the routing comprises selecting at least one down-going port and at least one up-going port. Further, the method and system can increase an accumulated downward weight on each selected down-going port by the receive weight of the routed end node, and increase an accumulated upward weight on each selected up-going port by the receive weight of the routed end node.

摘要： Systems and methods for using queue pair 1 (QP1) for receiving multicast based announcements in multiple partitions in a high performance computing. In accordance with an embodiment, by extending the scope of QP1 to also include receiving and sending multicast packets in any partition defined for the port, it is possible to implement generic MC based announcement and discovery without requiring the complexity of unique QPs for individual partitions, nor any update of QP configuration as a consequence of change of partition membership.

摘要： Systems and methods for supporting efficient virtualization in a lossless interconnection network. An exemplary method can provide, one or more switches, including at least a leaf switch, a plurality of host channel adapters, wherein each of the host channel adapters comprise at least one virtual function, at least one virtual switch, and at least one physical function, a plurality of hypervisors, and a plurality of virtual machines, wherein each of the plurality of virtual machines are associated with at least one virtual function. The method can arrange the plurality of host channel adapters with one or more of a virtual switch with prepopulated local identifiers (LIDs) architecture or a virtual switch with dynamic LID assignment architecture. The method can assign each virtual switch with a LID. The method can calculate one or more linear forwarding tables based at least upon the LIDs assigned to each of the virtual switches.

摘要： Starting a spanning tree protocol (STP) process in a network device excludes performing a root bridge election sequence. The network device receives and learns the STP roles and STP states of its ports based on the received bridge protocol data units (BPDUs) during a quiescent period of time subsequent to starting STP processing. Port role and port state learning occur absent the generation and transmission of BPDUs during the quiescent period of time. Subsequent to the end of the quiescent period, the network device commences generating and transmitting BPDUs.

摘要： The subject technology addresses a need for improving utilization of network bandwidth in a multicast network environment. More specifically, the disclosed technology provides solutions for extending multipathing to tenant multicast traffic in an overlay network, which enables greater bandwidth utilization for multicast traffic. In some aspects, nodes in the overlay network can be connected by virtual or logical links, each of which corresponds to a path, perhaps through many physical links, in the underlying network.

摘要： A wireless sensor network (WSN) clustering routing method based on optimization with salp swarm algorithm includes: S1: constructing an objective function by comprehensively considering factors as follows: node residual energy, a distance between cluster head nodes, a distance between a cluster member node and a cluster head node, a distance from a node to a base station, and a number of cluster head nodes; S2: solving the objective function by using a salp swarm algorithm, to find an optimal clustering scheme, and thus dividing the WSN into non-uniform clusters, wherein in each cluster, the cluster member node sends data to the cluster head node in a single-hop manner; S3: constructing a minimum spanning tree with the base station as a root node by using a routing utility function ƒ(CHi); S4: sending, by the cluster head node, data to the base station through routing organized by the minimum spanning tree.
