Patent number: 11283649Abstract: Methods, computer program products, and systems are presented. The method computer program products, and systems can include, for instance: receiving, by a Network Virtualization Edge (NVE) of a first virtual network (VN), a multicast packet from a virtual machine (VM) of the first virtual network (VN); determining, by the NVE, whether the NVE currently supports forwarding the multicast packet to a second NVE of a second virtual network (VN), the second virtual network (VN) being logically separated from the first virtual network (VN); responsively to determining that the NVE currently supports forwarding the multicast packet to a second NVE of a second virtual network (VN) forwarding, by the NVE, the multicast packet to the second NVE.Type: GrantFiled: September 30, 2019Date of Patent: March 22, 2022Assignee: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Kai Hong Du, Heng Guo Ge, Shashi Pratap Singh, Lin Wei Wu, Le Od Zhang

Patent number: 10684882Abstract: Methods, computer program products, and network authority devices are presented. The methods include, for instance: updating a source network with migration information of a virtual machine to redirect network traffic for the virtual machine to a destination network; and updating at least one remote network with the migration information of the virtual machine. In one embodiment, the updating includes updating the source network concurrent with a migration of the virtual machine to minimize interruption of the network traffic. In another embodiment, the updating includes updating a network device of the source network to forward the network traffic for the virtual machine to another network device of the destination network. In a further embodiment, the updating includes updating the source network to redirect the network traffic from at least one client on the at least one remote network.Type: GrantFiled: December 27, 2017Date of Patent: June 16, 2020Assignee: International Business Machines CorporationInventors: Jing Lu, Heng Guo Ge, Da Shen, Jun Yao

Patent number: 10237083Abstract: In an approach to routing and forwarding a data packet with a forwarding RBridge and a corresponding RBridge, a computer, in response to receiving a TRILL data packet, performs the following steps: parsing a TRILL header of the TRILL data packet, and acquiring an egress RBridge nickname of the TRILL data packet; obtaining routing information corresponding to the egress RBridge nickname, wherein the information indicates whether the forwarding RBridge is the penultimate hop RBridge on the forwarding path to which the egress RBridge nickname is corresponding; and in response to the indication in the information that the forwarding RBridge is the penultimate hop RBridge on the forwarding path to which the egress RBridge nickname is corresponding, stripping the TRILL header of the TRILL data packet off to obtain an original data packet, and forwarding the original data packet to the egress RBridge from an out port specified by the information.Type: GrantFiled: August 14, 2015Date of Patent: March 19, 2019Assignee: International Business Machines CorporationInventors: Kai Hong Du, Heng Guo Ge, Fu Hui Li, Jiu Xing Nie, Da Shen
