Techniques are disclosed for allocation of resources under the control of resource managers and the choice and coordination of resource acquisition protocols to communicate with these resource managers. The resource managers may be distributed and heterogeneous. For example, a technique for use by a service provider for allocating one or more resources from multiple resources associated with multiple resource managers based on at least one service agreement offer from a service client comprises the following steps/operations. At least one service agreement offer is obtained. A resource allocation is automatically determined based on the obtained service agreement offer. The automated step/operation of determining the resource allocation comprises: (i) coordinating selection of a resource acquisition protocol from among multiple resource acquisition protocols for use in communicating with the multiple resource managers to acquire one or more resources associated therewith; and (ii) evaluating a performance associated with one or more of the multiple resource acquisition protocols.

A method for connecting a terminal to a telecommunication network via an access point. After a request to connect a terminal to a first access point, the first access point determines if it has access to a resource for serving the terminal and, if possible, serves the terminal. If not, the first access point requests, from at least one second access point to which is it connected, a resource for serving the terminal; and in the event that the resource is available to the second access point, the first access point transfers, to the terminal, data for enabling the terminal to connect to the second access point.

Proposed are a virtual guest management system and a virtual guest management method capable of improving the usage efficiency of resources. In a virtual guest management system comprising a plurality of virtual hosts, a virtual guest arranged in each of the plurality of virtual hosts, and a management system that manages migration of the virtual guest, the management system adds a used resource history of a migration-target virtual guest to a used resource history of a destination candidate virtual host, estimates the used resource history of the destination candidate virtual host upon assuming that the migration-target virtual guest was migrated, and determines the destination virtual host among the destination candidate virtual hosts based on an estimated result.

A system, a method, and a computer program are provided for provisioning a network connectivity link to a node in a virtual private network. The method includes receiving a connectivity link change request that includes a request to change a bandwidth allocation for the network connectivity link, retrieving network connectivity information, applying the request to change the bandwidth allocation to the current bandwidth value and changing the bandwidth allocation for the connectivity link, evaluating the bandwidth values for all network connectivity links in the virtual private network, determining whether the sum of bandwidths exceeds the aggregate bandwidth value, and configuring a router with the updated bandwidth allocation to effectuate the updated bandwidth allocation in said network connectivity link.

Systems and methods of adaptive bandwidth (BW) management are provided by a control unit of distribution and central units to monitor power and traffic loads at a plurality of nodes in a network; a BW management unit communicating with the control unit to reassign a set of network slices with a set of smaller bandwidth parts (BWPs); the BW management unit configured to define a smaller BWP from a slice mapping for the slice reassignment during a AC power outage, the slicing mapping includes network slices tied to smaller BWPs in the network; and the BW management unit configured to adapt BW for users at the node by reassigning of at least one network slice with a defined smaller BWP at the node in response to a condition determined by the BW management unit, the condition of at least one of a AC power outage, and reduced traffic load at the node.

[Problem] When a resource reserved in a resource sharing system become unavailable, the reservation is efficiently reset.

[Solution] A resource sharing system 10 shares resources 30 with a plurality of users 20 (user terminals). A resource reservation management device 42 includes: a reservation setting unit 402 that accepts a reservation request for the resource 30 from the user 20, and sets a reservation on a predetermined resource 30 in the resource sharing system 10; and a reservation changing unit 404 that resets the reservation to another resource 30 in the resource sharing system 10 in case the predetermined reserved resource 30 becomes unavailable. if the other resource 30 has insufficient resource capacity, the reservation changing unit 404 resets the reservation to the other resource 30 based on a reservation changing policy defining which reservation is preferentially reset out of the reservation to be reset.

Aspects involve an apparatus, device, systems, and methods for instantiating and operating a cloudless infrastructure of computing devices that communicate peer-to-peer and mostly off-grid (or otherwise without communicating through a conventional centralized network) to share resources, access, and provide services and applications, store and access data and other information, and the like. The systems may provide services to connecting computing devices, such as user devices, personal computing devices, mobile devices, laptops, personal computers, Internet of Things (IoT) devices etc., in communication with one or more of the nodes of the infrastructure. The infrastructure exchanges or manages communications, transactions, and/or data in a cloudless and/or decentralized environment to freely exchange information between the nodes to allow the infrastructure to scale in response to client demands, adapt the infrastructure to a failed node with minimal impact on connected computing devices, and provide robust security to customer information, communications, and devices.

A method includes, in response to receiving a request for a graphical visualization of a microservice mesh comprising one or more nodes, obtaining information associated with services operating at the one or more nodes and connections between the one or more nodes. The method further includes determining, in view of the information, one or more types of requests associated with each of the services. The method further includes generating the graphical visualization of the microservice mesh. The graphical visualization includes a first vertex corresponding to a particular service and a second vertex corresponding to a type of a request received by the service. The first vertex and second vertex are connected by an edge that corresponds to the request.

Performance issues in a service function chain having a plurality of resources and a plurality of network functions each having a network function queue are diagnosed. Each network function queue is monitored and queueing information for input packets for each of the plurality of network functions is dumped to a data store. Each resource that is under contention is identified as well as which of the network functions is a contender for the resources. A diagnosing algorithm is used to diagnose performance problems and an impact graph for each victim packet is generated. A summary of results as a list of rules is then provided.
