Disclosure method that includes traversing a user instance distribution of user instances of a user on hosts in a cluster to detect whether a trigger condition for user scheduling of adjustment of the user instance distribution is satisfied; migrating the user instance to be migrated out from the one or more hosts from which the user instances are to be migrated out to the one or more second hosts to which the one or more user instances are to be migrated in if the trigger condition for user scheduling is satisfied. The implementations of the present disclosure may schedule resources based on user instance distributions of users on hosts and achieve a balanced distribution of user instances. The implementations further avoid placing user instances of all users into a small number of hosts, increase the ability to prevent risks, and enhance the user experience.

A control device that performs resource allocation to a network including a transmission device, one or more transfer devices, and a reception device as nodes, the control device including a schedule database unit that holds schedules of time slots not allocated to specific communication, the schedules being set in advance for respective nodes of the network, and a schedule processing unit that, in a case where a communication request is received, selects a time slot that satisfies a transmission request amount of the transmission device on the basis of remaining transmittable amounts of respective time slots in the schedules and notifies the transmission device of a selected time slot.

Methods, systems, and devices are described for providing dynamic spatial allocation of satellite capacity based on aircraft load forecasting. In embodiments, a satellite communications system provides network access service over a service area via a plurality of satellite user beams, predicts spatial network resource demand for the service area over one or more service periods based at least in part on forecasted travel paths of a plurality of mobile multi-user terminals over the one or more service periods and respective predicted service demands for the plurality of mobile multi-user terminals, determines a satellite capacity resource configuration for the plurality of satellite user beams for the one or more service periods based on the predicted spatial network resource demand, and then adapts at least one characteristic of the plurality of satellite user beams for the one or more service periods based on the determined satellite capacity resource configuration.

Provided are a computer program product, system, and method for resource allocation in accordance with one embodiment of the present description, in which a resource allocation such as a buffer credit allocation for a port in a storage area network is initialized as a function of a measurement of a length of a communication link for the port of the storage area network. In one embodiment, the length measurement is a function of a minimum command response time of a command issued over the communication link. Other aspects of resource allocation in accordance with the present description are described.

A method for managing transmission resources in a SIP-based communication system by a SIP registrar server can include receiving a first number of register requests from a first client from the number of clients, each register request corresponding to one slot in the predetermined first time period; receiving a second number of register requests from a second client of the number of clients, each register request corresponding to one slot in the predetermined first time period, wherein the second number of register requests exceeds the acceptable predetermined number of register requests for the second client, and assigning a number of slots not used by the first client within the predetermined first time period to the second client for sending the register requests which exceed the acceptable predetermined number of register requests for the second client. A system for implementation of the method and an apparatus can be utilized in embodiments of the method and the system.

Systems and methods for preemptive adjustments of connections in a server connection pool are provided. In example embodiments, a number of quality of service engines analyze server connection pool metrics data to generate instructions to increase or decrease the number of connections in a connection pool, preemptively, before shortages or surpluses of connections occur. Corrective engines can analyze performance of the quality of service engines and can, when necessary, instruct the quality of service engines to modify their prediction mechanisms.

Systems and methods for allocating resources. The system includes a communications module, a processor, and a memory. The memory stores a data record and instructions that, when executed, configure the processor to obtain a data record and transmit an existing score indication corresponding to the data record for display at the client device; receive a first time parameter and an action indicator associated with a shared resource and, in response, determine a first provisional score corresponding to the data record based on the existing score indication, the action indicator, and the first time parameter to provide a first provisional score indication; transmit the first provisional score indication and a selectable option associated with the action indicator for display at the client device while the first provisional score indication is displayed; and in response to receiving a resource transfer instruction, allocate the shared resource associated with the action indicator.

A computer apparatus (e.g. a server) and a method for managing transmission resources in a SIP-based communication system can include use of a SIP registrar server that is adapted to receive register requests from a number of clients connected to the SIP registrar server via a communication network. Each client can be granted a predetermined number of register requests in a predetermined first time period where each register request corresponds to a slot. In the first time period, at least one slot not used by a first client can be lent to a second client. In a second time period, the at least one slot lent to the second client can be reclaimed by the first client or another client. The reclaiming of the lent slot(s) can include making the second client function as a proxy for other clients according to a third party registration process.

A transmission device includes at least one port, first and second transceivers, and a processor. The first transceiver transmits or receives a frame signal to or from one adjacent node within a ring network including a plurality of nodes. The frame signal includes an overhead and a plurality of slots. The second transceiver transmits or receives a frame signal to or from another adjacent node within the ring network. The processor sets port information to the overhead of a frame signal to be transmitted from the first transceiver. The processor acquires slot information from the overhead of a frame signal received by the first transceiver or the second transceiver based on the port information. The processor sets a received data signal in a slot allocated based on the slot information, among the plurality of slots of a frame signal to be transmitted from the first transceiver or the second transceiver.

Examples described herein provide a packet ingress and egress system with a memory buffer in a network device. The ingress and egress system can generate a time stamp for one or more received packets at an ingress port, allocate a received packet to a queue among multiple queues, and permit egress of a packet from a queue. An ingress port can have one or more queues allocated to store received packets. An egress port can use the one or more queues from which to egress packets. A maximum size of a queue is set as the allocated memory region size divided by the number of ingress ports that use the allocated memory region. An egress arbiter can apply an arbitration scheme to schedule egress of packets in time stamp order.
