This application provides a resource reservation method and an apparatus. The method includes: receiving, by a node, a first message, where the first message carries a bandwidth value r1 of a resource requested to be reserved and a quantity Q1 of cycles occupied by the resource, the node maintains resource reservation states in K cycles, K is a positive integer, and Q1 is less than or equal to K; and updating, by the node, resource reservation states in Q1 of the K cycles based on the bandwidth value r1 and the quantity Q1. The node maintains the resource reservation states at a granularity of cycles. Therefore, the resource reservation states that need to be maintained by the node do not depend on a quantity of data flows processed by the node, and a performance requirement of a resource reservation for the node can be lowered.

A method comprises initiating a first application in a first one of a plurality of distributed processing nodes, and responsive to initiation of the first application, identifying a plurality of beacon entities to be contacted in conjunction with execution of at least a portion of the first application. The method also comprises, for each of at least a subset of the identified beacon entities, initiating an additional application in an additional one of the plurality of distributed processing nodes. The method further comprises aggregating processing results from the first and one or more additional processing nodes, and providing the aggregated processing results to a client. The plurality of distributed processing nodes may comprise a plurality of YARN clusters associated with respective data zones, with each of the clusters being configured to perform processing operations utilizing local data resources locally accessible within its corresponding data zone.

A method comprises configuring a first metagenomics sequencing center to perform metagenomics sequencing on a first set of biological samples, and processing metagenomics sequencing results from the first metagenomics sequencing center with additional metagenomics sequencing results from one or more other metagenomics sequencing centers for respective additional sets of biological samples in conjunction with associated epidemiological data accessible to respective ones of the first and additional metagenomics sequencing centers. The processing is configured to generate global view information characterizing epidemiological relationships between the metagenomics sequencing results from the first and additional metagenomics sequencing centers. The method further includes providing the global view information to a requesting client.

A first portion of a distributed catalog service is implemented for a given one of a plurality of distributed processing node clusters associated with respective data zones, each of the clusters being configured to perform processing operations utilizing local data resources locally accessible within its corresponding data zone. The first portion of the distributed catalog service receives a request to identify for each of a plurality of data resources to be utilized by an application initiated in the given cluster whether the data resource is a local or remote data resource relative to the given cluster, and provides a response to the request. The first portion of the distributed catalog service in combination with additional portions implemented for respective additional ones of the distributed processing node clusters collectively provide the distributed catalog service with capability to resolve local or remote status of data resources in each of the data zones.

Examples allocating resources to virtual network functions (VNFs). Some examples include monitoring information associated with a set of VNFs that includes a set of VNF instances. A resource allocation event may be predicted for a VNF instance based on the monitored information and a resource flexing model that is developed using a capacity metric of the VNF instance. A resource flexing plan may be generated based on the resource allocation event and an order of the set of VNFs in a service function chain.

The present document describes a method (900) for establishing control information for a control policy of a client (102) for streaming data (103) from at least one server (101, 701). The method (900) comprises performing (901) a message passing process between a server agent of the server (101, 701) and a client agent of the client (102), in order to iteratively establish control information. Furthermore, the method (900) comprises generating (902) a convergence event for the message passing process to indicate that the control information has been established.

Providing fluid external access to a resource that is internal to a network from external to that network. From within the network, the internal user simply provides an internal identifier, and the external user accesses not the internal identifier, but an external uniform resource identifier (URL) that the external user can simply select to obtain access to the internal resource of the network. This is accomplished by translating the internal identifier to an external URL having a proxy server as its domain name. When the external URL selects the URL, a request with that external URL is made to the proxy server, which translates the external URL back to the internal identifier, and coordinates with the network to obtain the resource for the external user.

A method and system for improving shared hardware and software resource system is provided. The method includes detecting and registering an Internet of things (IOT) device connected to a network. Hardware/software resources and sensors associated with hardware and software operations executed by the IOT device are identified and all available data and associated metadata associated with the hardware/software resources and the sensors are stored in a database. Additional available hardware/software resources and sensors associated with a plurality of IOT devices connected to the network are displayed and a command signal for assigning a specified hardware/software resource or sensor to the IOT device is executed. A network identification code associated with a location of the specified hardware/software resource or sensor is retrieved and enabled with respect to said IOT device.

Embodiments of the present invention provide a system for consolidating and processing multiple resource requests. The system is configured for receiving at least two resource requests from a first user, identifying that the at least two resource requests are associated with a second user, consolidating the at least two resource requests, and processing the consolidated at least two resource requests.

Some embodiments provide a novel method for deploying different virtual networks over several public cloud datacenters for different entities. For each entity, the method (1) identifies a set of public cloud datacenters of one or more public cloud providers to connect a set of machines of the entity, (2) deploys managed forwarding nodes (MFNs) for the entity in the identified set of public cloud datacenters, and then (3) configures the MFNs to implement a virtual network that connects the entity's set of machines across its identified set of public cloud datacenters. In some embodiments, the method identifies the set of public cloud datacenters for an entity by receiving input from the entity's network administrator. In some embodiments, this input specifies the public cloud providers to use and/or the public cloud regions in which the virtual network should be defined. Conjunctively, or alternatively, this input in some embodiments specifies actual public cloud datacenters to use.
