Methods, apparatuses, and computer program products for estimating physical disparity for data locality in software-defined infrastructures are disclosed. For each node in a cluster of nodes connected to a switch, vital product data (VPD) of a cable connecting the node to the switch is obtained, and for each cable, a length of the cable is determined from the VPD. A management application assigns a group identifier to each node in the cluster based on the length of the cable connecting the node to the switch. The management application selects a node in the cluster for storing a data set in dependence upon the group identifier of the node.

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.

The technology disclosed relates to detection and resolution of conflicts between requested internet services and package of internet services associated with a domain. The method disclosed includes receiving a request from a client to add a requested internet service to a package of internet services. The method includes searching a domain name system (DNS) database for DNS records or a DNS server for external domains having attribute fields indicating attributes of the internet services in the package of internet services. The method includes comparing attributes of the requested internet service to attribute fields for the internet services in the package of internet services using a set of conflict definitions to identify attributes of the internet service requested conflicting with attributes of the package of internet services. When conflicting attributes are identified, the method includes invoking a resolution process to resolve the conflict.

The technology disclosed relates to resolution of conflicts between a requested internet service, requested by an internet service requesting server, and a package internet services. The method disclosed includes sending a conflict check result message to an internet service requesting server, indicating a presence of a conflict between a requested internet service requested by the requesting server and a package of internet services. The method includes receiving from the internet service requesting server a response including a selection from (i) an alternate internet service in the package of internet services to substitute for the requested internet service; (ii) a request to replace an existing connection with a service in the package of internet services with the requested internet service; and (iii) a request to initiate a custom resolution application. The method then responsively performs a respective conflict resolution step.

In one embodiment, a first networking device associated with a switched network comprises one or more processors and one or more computer-readable media storing computer-executable instructions that, when executed, cause the one or more processors to perform acts comprising configuring, on the first networking device, a network-address-translation (NAT) rule indicating that a first multicast group is to be translated to a second multicast group. The acts further include, at least partly in response to the configuring of the NAT rule, storing the NAT rule at the first networking device, generating a message indicating the NAT rule, and sending the message to at least a second networking device associated with the switched network.

An Internet of Things (IoT) network includes an IoT device with a communicator to send a communication including egress frame, protocol library builder to determine available protocols, frame analyzer to analyze an ingress frame, and frame builder to build the egress frame from the ingress frame. An IoT network includes an IoT device with network discoverer to identify available parallel communication channels between IoT device and target device, payload, payload fragmenter/packager to fragment the payload into sub-objects for transmission, and packet communicator to send sub-objects to the target device over parallel communication channels. An IoT network includes a plurality of IoT devices, which each include a communication channel to an upstream device, a network link to another one of the plurality of IoT devices, a hash calculator to identify a neighbor IoT device, and a communicator to send out a message to the neighbor IoT device.

In one embodiment, a computer-implemented method comprises storing, in one or more data repositories, a plurality of channel records, each channel record including a channel identification (ID) and channel status indicator; receiving, at a computing device, a join request for a client account to join a channel, the join request including a first channel ID; determining whether a channel record of the plurality of channel records stored in the one or more data repositories includes a channel ID that matches the first channel ID; in response to determining that each channel record of the plurality of channel records does not include a channel ID that matches the first channel ID, creating and storing, in the one or more data repositories, a first channel record that includes: the first channel ID and a channel status indicator set to active; receiving, at the computing device, a first notification from a programmed message transport service that a channel corresponding to the first channel ID is set to inactive; in response to receiving the first notification, updating the channel status indicator of the first channel record in the one or more data repositories to indicate that the channel is inactive; receiving, at the computing device, a first request to broadcast a message to a channel corresponding to the first channel ID; in response to receiving the first request to broadcast the message to the channel corresponding to the first channel ID, determining that the channel status indicator of the first channel record is set to inactive and blocking the broadcast of the message to the programmed message transport service.

The present disclosure relates to network connection methods and devices for connecting a terminal device to a network through a network access device. The network access device may include a processor and a connection configuration component. The processor receives a connection request from the terminal device. The processor also authenticates the terminal device based on the connection request, and obtains a verified Internet protocol (IP) address from the connection configuration component. The processor further transmits the verified IP address to the terminal device after the terminal device is authenticated, wherein the terminal device is configured to be connected to the network by using the verified IP address.
