Patent number: 11917523Abstract: A polymorphic network control system and a polymorphic network control system method supporting terminal mobile access. A network architecture is redesigned based on the idea of separation of an identifier from a locator. In this network mode, the three-layer protocol is no longer a traditional IP message, but a message carrying a locator and an identifier. The polymorphic SDN network controller is responsible for forwarding the data packet to a destination corresponding to a destination locator. When the network location of a mobile device is changed, the transmission connection established based on the identifier will suspend communication due to the disconnection of the physical link. When the mobile device is re-accessed and a new forwarding path is established, the transmission connection can recover communication.Type: GrantFiled: May 30, 2023Date of Patent: February 27, 2024Assignees: ZHEJIANG LAB, INFORMATION ENGINEERING UNIVERSITYInventors: Zhongxia Pan, Peng Yi, Le Tian, Tao Zou, Juan Shen

Patent number: 9836712Abstract: A method and information processing system manage workflow instance migration. A received migration plan indicates a set of workflow migration points associated with an initial workflow process model. The set of workflow migration points is associated with a set of workflow activities of the initial workflow process model. At least one workflow instance is selected from a set of workflow instances. A current migrateability state associated with the selected workflow instance is determined based at least on the set of workflow migration points. Migration of the workflow instance to a new workflow process model is granted in response to determining that the current migrateability state is set to migrateable. Migration of the workflow instance to the new workflow process model is prevented for at least a given amount of time in response to determining that the current migrateability state fails to be set to migrateable.Type: GrantFiled: August 10, 2012Date of Patent: December 5, 2017Assignee: International Business Machines CorporationInventors: Liana L.

Patent number: 8498890Abstract: A method and information processing system manage workflow instance migration. An initial workflow process model is compared with a new workflow process model. A set of differences between the initial workflow process model and the new workflow process model are determined. At least one set of activities associated with the initial workflow process model that is migrateable to the new workflow process model is identified based on the set of differences. A migration plan associated with the initial workflow process model and the new workflow process model is generated. The migration plan includes the at least one set of activities associated with the initial workflow process model. The migration plan is then used to evaluate a set of workflow instances associated with the initial workflow process model and migrate one or more of these workflow instances to the new workflow process model based thereon.Type: GrantFiled: September 18, 2009Date of Patent: July 30, 2013Assignee: International Business Machines CorporationInventors: Liana L.
