A distributed processing method based on a consistency protocol is provided. The method includes: transmitting a decree prepare request including a first decree number, the decree prepare request requesting other nodes to promise to no longer accept a fast write operation initiated by a leader node whose leader number is less than the first decree number, the first decree number representing a leader number of a current node, and the leader number representing a number of a decree at which the current node that becomes a leader node is located; and in response to receiving decree promises from at least a preset quantity of nodes among the other nodes, enabling the fast write operation from a subsequent decree number of a second decree number determined based on the decree promises, each of the decree promises including the first decree number.

A method includes defining a first specification for a first network slice, determining a first equilibrium value for a first time period for the first network slice offering, receiving a first bid price for the first network slice for the first time period from a first customer, comparing the first equilibrium value to the first bid price; and providing services using the network slice to the customer during the time period in accordance with the first specification and the bid price if the bid price meets or exceeds the equilibrium value.

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.

An information processing apparatus including: a memory; and a processor coupled to the memory, the processor being configured to: in a network coupling a plurality of storage nodes, at least one proxy, and at least one client; collect information of accesses executed most by the at least one client via the at least one proxy on a path of each access; based on the information of accesses, calculate network distances between the plurality of storage nodes and the at least one proxy; and based on the network distances, determine a leader to be one of the plurality of storage nodes that is close to one of the at least one proxy accessed most frequently.

A computer manages reconfigurations of a Byzantine fault-tolerant, distributed computing system comprising a network of first nodes adhering to a given consensus protocol at a reconfiguration service. The computer services the network by receiving a request of change of status of a second node with respect to the network. The computer informs at least a subset of the first nodes of the received request. The computer obtains an approval of the request, whereby at least a subset of the first nodes collectively approve the change of status as a result of contributions processed according to the given consensus protocol. The computer updates a configuration log according to request approvals obtained by servicing the network. The computer addresses requests of clients about configurations of the network based on the updated configuration log.

A method for managing a controller function of investigator equipment belonging to a backhaul network, the backhaul network comprising a plurality of items of equipment managing a unified wireless network. Each item of equipment the controller function of which is active fulfils a role of controller. The investigator equipment can activate and deactivate the controller function without requiring rebooting. The method comprises: recording age of investigator equipment corresponding to a time since which the equipment has been fulfilling the role of controller, broadcasting discovery request, determining that responding equipment is fulfilling role of controller according to information representing role of controller present in response from the responding equipment, when the controller function of the investigator equipment is active, obtaining the age of the responding equipment, and deactivating the controller function of the investigator equipment if the age of the investigator equipment is less than the age of the responding equipment.

Various approaches for providing network maintenance and health monitoring. In some cases, some approaches include systems, methods, and/or devices that provide for receiving and cataloging network incidents and invoking automated remediation in relation to network incidents.

A computer system synchronizes data in an edge computing network. A leader node is elected from a plurality of nodes, wherein the plurality of nodes includes a plurality of follower nodes that each cast a single vote for a candidate node, and wherein the candidate node is elected as the leader node in response to the candidate node receiving votes from a majority of the nodes. The leader node receives a request from a follower node comprising data to be replicated across the nodes, and transmits the data to the other nodes. When a majority of nodes receive the data, the leader node transmits instructions to the nodes to cause each node to commit the data to a data log maintained by each node. Embodiments of the present invention further include a method and program product for synchronizing data in substantially the same manner described above.

A method includes defining a first specification for a first network slice, determining a first equilibrium value for a first time period for the first network slice offering, receiving a first bid price for the first network slice for the first time period from a first customer, comparing the first equilibrium value to the first bid price; and providing services using the network slice to the customer during the time period in accordance with the first specification and the bid price if the bid price meets or exceeds the equilibrium value.

An apparatus in one embodiment comprises a processing platform that includes a plurality of processing devices each comprising a processor coupled to a memory. The processing platform is configured to implement at least a portion of at least a first cloud-based system. The processing platform comprises a modelling language extension module configured to implement artificial intelligence-based decision points into a process flow and compile context attributes associated with the artificial intelligence-based decision points based on data from artificial intelligence systems. The processing platform also comprises a process engine configured to convert the artificial intelligence-based decision points and context attributes to input to a process optimization algorithm, and an optimization engine configured to determine, by applying the process optimization algorithm to the converted input, an overall execution path within the process flow, and output a decision to a first of the artificial intelligence-based decision points based on the overall execution path.
