Patent number: 11395308Abstract: Systems and methods for allocating edge computing resources may receive a predicted user route defining multiple wireless access points available along the route at respective time points and an assured delay constraint, determine, for each wireless access point, datacenters in the network meeting the assured delay constraint when accessed through the wireless access point, and construct an auxiliary graph dependent on the predicted user route and the determined datacenters. Each determined datacenter is represented by at least one node in the graph and each path in the graph defines a sequence of datacenters and a corresponding sequence of wireless access points through which they are accessible. A lowest cost path in the graph is determined and the sequences of datacenters and wireless access points defined by the lowest cost path are provided to a resource orchestrator that allocates edge computing resources for a mobile user traversing the predicted user route.Type: GrantFiled: April 30, 2019Date of Patent: July 19, 2022Assignee: Fujitsu LimitedInventors: Qiong Zhang, Qingya She, Weisheng Xie, Paparao Palacharla, Tadashi Ikeuchi

Patent number: 10432552Abstract: 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.Type: GrantFiled: May 11, 2018Date of Patent: October 1, 2019Assignee: Fujitsu LimitedInventors: Qiong Zhang, Paparao Palacharla, Weisheng Xie, Qingya She, Tadashi Ikeuchi

Patent number: 10432537Abstract: 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.Type: GrantFiled: May 11, 2018Date of Patent: October 1, 2019Assignee: Fujitsu LimitedInventors: Qiong Zhang, Qingya She, Weisheng Xie, Paparao Palacharla, Tadashi Ikeuchi

Patent number: 9565101Abstract: A method employing resource orchestration algorithms may find a fewest number of working data centers (DCs) to guarantee K-connect survivability using an overlay network representing a physical optical network. The overlay network may not include certain topological features of the physical optical network. A risk-based algorithm may result in fewer working DCs for K-connect survivability. A delay-based algorithm may be more suitable for delay-sensitive cloud applications.Type: GrantFiled: December 10, 2013Date of Patent: February 7, 2017Assignee: Fujitsu LimitedInventors: Qiong Zhang, Qingya She, Xi Wang, Paparao Palacharla, Motoyoshi Sekiya
