  • Publication number: 20180262431
    Abstract: A resource orchestration framework may include vertices representing physical network nodes and a resource orchestrator. The resource orchestrator may receive a service function chain request specifying service functions to perform on respective physical nodes and a first starting time for launching a first one of the service functions. The resource orchestrator may determine an ending time for performing the first service function that, with the first starting time, defines a time duration for the first service function, identify vertices at which the first service function is available during the time duration, map a first vertex to the first service function in a candidate service function chain, determine a second starting time for launching a second one of the service functions dependent on the first starting time, and provide the candidate service function chain, the first starting time, and the second starting time to a neighbor vertex of the first vertex.

  • Publication number: 20180262443
    Abstract: A resource orchestration framework may include vertices representing physical network nodes and a resource orchestrator. The resource orchestrator may obtain a service function chain specifying, for multiple service functions, mappings of the service functions to respective physical nodes along a specified forwarding path, and a first starting time at which to instantiate resources for a first service function in the chain on the first mapped physical node. The resource orchestrator may instantiate the resources for the first service function on the first mapped physical node at the first starting time, prior to arrival of a first packet in a packet flow for the service function chain at the first mapped physical node and, subsequently, instantiate resources for a second service function in the chain on the second mapped physical node at a second starting time, prior to arrival of the first packet at the second mapped physical node.

  • Publication number: 20180227244
    Abstract: Systems and methods for identifying a mapping solution for a virtual network request are disclosed. A resource orchestrator may receive a virtual network request specifying resources required on physical nodes in a network and generate a mapping solution for the request. Generating the mapping solution may include identifying vertices at which a first resource is available, mapping each identified vertex to the first resource in a respective candidate chaining solution, determining, for each identified vertex, a number of messages including the candidate chaining solution to be forwarded to respective neighbor vertices, and forwarding the determined number of messages to the respective neighbor vertices. Determining the number of messages to be forwarded may include applying a message forwarding policy to reduce the total number of messages forwarded between vertices when generating the mapping solution. The policy may be dependent on the topology of the virtual network request.

  • Publication number: 20180227243
    Abstract: Systems and methods for performing distributed virtual network embedding are disclosed. A resource orchestrator may receive a virtual network request specifying a set of virtual nodes, a set of virtual links, each connecting two virtual nodes in a mesh topology, and resource requirements for some virtual nodes. The orchestrator may partition the virtual network request into multiple sub-requests, each specifying a linear topology for a subset of the virtual nodes and links within the mesh topology. The sub-requests may collectively include all virtual links within the mesh topology with no overlapping links. Resource orchestrators may collaborate to compute, independently for each sub-request, a respective chaining solution in which each virtual node is mapped to a physical node having resources sufficient to implementing the virtual node. A resource orchestrator may combine the respective chaining solutions for each of the sub-requests to generate a mapping solution for the virtual network request.

  • Publication number: 20180219762
    Abstract: In one or more embodiments, one or more systems, methods, and/or processes may receive a service function chain description that includes service functions associated with multiple domains, and rather than any of the domains ignoring or rejecting outside nodes, nodes may be configured to communicate with the outside nodes in implementing a service function chain associated with the service function chain description. For example, an arbiter (e.g., a central arbiter) may provide control information and/or configuration information, based on the service function chain description, to one or more systems of each domain. In one instance, the arbiter may provide the control information and/or the configuration information to a border node of each domain. In another instance, the arbiter may provide the control information and/or the configuration information to a domain controller of each domain.

  • Patent number: 10038496
    Abstract: Methods and systems for determining optical network utilization efficiency include generating a random demand set and calculating a demand fill ratio (DFR) based on the random demand set. The random demand set includes network demands for a given optical network topology that provide 100% of the wavelength slots in the optical network topology. The DFR may be calculated using different wavelength assignment algorithms, such as a first fit wavelength assignment algorithm, from the randomly generated demands in the random demand set. The DFR may be calculated without and with wavelength conversion nodes.

  • Patent number: 10012716
    Abstract: In an MRI method and apparatus a 3D magnetic resonance scan sequence is performed to acquire MR raw data, which are entered into k-space with 2D CAIPIRINHA undersampling. The sampled data are reorganized into data blocks that each contain one sampled k-space location. The data blocks are extracted from k-space in a predetermined sequence, and image data are reconstructed from the k-space data respectively in the extracted data blocks. The application of the 2D CAIPIRINHA undersampling method with corresponding reorganized data blocks into a 3D scan sequence, in particular a SPACE scan sequence, significantly improves the comfort of an examination subject as well as the overall image quality thereof.

  • Patent number: 9998563
    Abstract: Systems and methods for performing vertex-centric service function chaining in multi-domain networks are disclosed. A resource orchestration framework of a multi-domain network may include vertices representing physical nodes and edges representing physical links in the network. A sole resource orchestrator (in a centralized system) or multiple resource orchestrators (each associated with a respective domain in a distributed system) may coordinate execution of a common compute function on multiple vertices to identify candidate service function chain solutions to a service function chain request. The request may specify a fixed-ordered chain or a flexible-ordered chain. The compute function may, during each of multiple supersteps, determine whether a partially mapped chain can be extended on a given vertex, send a controller message to a neighbor vertex with which it has a qualified link, or return a completed chain, which may be selected for execution, dependent on applicable policies.
