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.

In one embodiment, a technique for load balancing of throughput for multi-PHY networks using decision trees is provided. A first device of a mesh communication network may collect at least one transmission metric indicative of a primary link and a secondary link between the first device and a second device of the mesh communication network. The first device may provide the at least one transmission metric as input to one or more decision trees comprising one or more attributes that are each indicative of a threshold for a corresponding transmission metric. The first device may obtain an output from the decision tree comprising a selection of either the primary link or the secondary link. The first device may send, based on the output from the decision tree, one or more packets to the second device using the selected link.

Provided are a service operation method, a service operation device a storage medium and an electronic device. The method includes: determining service information about multiple nodes in a distributed network after determining a link failure in the distributed network, computing a restore path centralizedly for services indicated by the service information about the multiple nodes, and operating the services by using the restore path.

Disclosed herein are systems and methods for scalable and secure transmission of multicast data over a public communication network. In exemplary embodiments of the present disclosure, a virtual overlay network can be presented as a single virtual interface to a computing device, for the receipt and transfer of multicast data in a secure and scalable manner across a public insecure communication network.

Example implementations relate to management of network topologies. A primary tree having multiple connection graphs is generated for each node in the network. Each connection graph has at least one ordered list of one or more network node connections and the generated connection graphs provide a full network fit for each node in the network. The connection graphs are stored in at least one network switch to be used for network switch functionality. Additional connection graphs are generated for one or more network nodes connections based at least on network link capacity and provide for sharing of one or more of network links between multiple network node connections. The additional connection graphs are stored in the at least one network switch to be used for subsequent network switch functionality.

Aspects and examples are disclosed for apparatuses and processes for establishing a communication link between a network using a routing protocol for low power and lossy networks (RPL) and a non-RPL-enabled device. For instance, a communication link establishment method includes establishing, by a routing protocol for low power and lossy networks (RPL) enabled device, a communication link with a non-RPL-enabled device. The method also includes establishing, by the RPL-enabled device, a network connection with an RPL-enabled network. Further, the method includes providing, by the RPL-enabled device, a proxy communication link between the non-RPL-enabled device and the RPL-enabled network. Providing the proxy communication link includes assigning a globally unique address (GUA) to the non-RPL-enabled device, and transmitting, by the RPL-enabled device, a proxy destination advertisement object to the RPL-enabled network where the proxy destination advertisement object comprises the GUA.

A mesh network system adapted for a wireless access point includes multiple mesh network nodes, which are a root node, relay nodes, and leaf nodes. The root node is communicatively connected to the wireless access point. The relay nodes and the leaf nodes are configured to receive a downlink message having a downlink destination address. When one of the relay nodes that receives the downlink message determines that the downlink destination address fails to match its mesh network address, the relay node queries a routing table to find a next-hop node address directing to the downlink destination address and forwards the downlink message to the mesh network node corresponding to the next-hop node address. When one of the leaf nodes that receives the downlink message determines that the downlink destination address fails to match its mesh network address, the leaf node discards the downlink message.

Systems and methods for InfiniBand fabric optimizations to minimize SA access and startup failover times. A system can comprise one or more microprocessors, a first subnet, the first subnet comprising a plurality of switches, a plurality of host channel adapters, a plurality of hosts, and a subnet manager, the subnet manager running on one of the one or more switches and the plurality of host channel adapters. The subnet manager can be configured to determine that the plurality of hosts and the plurality of switches support a same set of capabilities. On such determination, the subnet manager can configure an SMA flag, the flag indicating that a condition can be set for each of the host channel adapter ports.

Systems, methods, and devices for offloading network data to a datastore. A system includes a publisher device in a network computing environment. The system includes a subscriber device in the network computing environment. The system includes a datastore independent of the publisher device and the subscriber device, the datastore comprising one or more processors in a processing platform configurable to execute instructions stored in non-transitory computer readable storage media. The instructions includes receiving data from the publisher device. The instructions include storing the data across one or more of a plurality of shared storage devices. The instructions include providing the data to the subscriber device.

Systems, methods, and devices for improved routing operations in a network computing environment. A system includes a virtual customer edge router and a host routed overlay comprising a plurality of host virtual machines. The system includes a routed uplink from the virtual customer edge router to one or more of the plurality of leaf nodes. The system is such that the virtual customer edge router is configured to provide localized integrated routing and bridging (IRB) service for the plurality of host virtual machines of the host routed overlay.
