Abstract: Methods and arrangements for facilitating virtual machine migration across data centers. A virtual machine is designated for migration from a first data center to a second data center, the virtual machine including a real identifier. A pseudo identifier is assigned to the virtual machine, and the pseudo identifier is mapped to the real identifier at a controller of the first data center. The real identifier is replaced in a data packet with the pseudo identifier for a routing task. Communication is maintained between the controller of the first data center and a controller of the second data center, and the controllers are synchronized to update a correct location of the virtual machine. The virtual machine is migrated from the first data center to the second data center.

Abstract: Techniques for providing session level replication and fail-over as a network service include generating a replication rule that replicates network traffic destined for a primary server from an originating server to a network controller and installing said rule in a switch component, identifying flows from the originating server to the primary server, replicating each incoming data packet intended for the primary server to the network controller for replication and forwarding to replica servers, determining said primary server to be in a failed state based on a number of retransmissions of a packet, to selecting one of the replica servers as a fail-over target, and performing a connection level fail-over by installing a redirection flow in the switch component that redirects all packets destined to the primary server to the network controller, which forwards the packets to the replica server and forwards each response from the replica server to said originating server.

There is offered to the client device two or more delivery schedules for delayed digital content delivery during the predetermined time period. Other variants and embodiments are broadly contemplated herein.

Abstract: Described herein are methods, systems, apparatuses and products for phase determination in an electricity grid. An aspect provides for determining phase for at least one electric grid device via receiving power consumption measurements derived from electricity grid devices connected in the electricity grid, comparing, over a series of time intervals, a total power consumed; and determining a phase for at least one electricity grid device.

Abstract: A system, and computer program product for mobile data transmission are provided in the illustrative embodiments. A request for data is received from a mobile device. A determination is made whether a data transmission over a mobile data communication network in response to the request can be delayed, forming a time-shifting determination. A determination is made, responsive to the time-shifting determination being affirmative, a delayed schedule for the data transmission in response to the request such that the data transmission is completed by a deadline. The data is transmitted over the mobile data communication network according to the delayed schedule.

Abstract: Systems and methods for effecting delayed delivery of data. There are received, at a scheduler, from a plurality of mobile computing devices, a plurality of requests for transmission of data objects. Responsive to the requests, communication is made to at least one of the devices at least one offer for a delayed transmission deadline of at least one data object. There is received, at the scheduler, at least one response to the at least one offer, and there is determined a scheduling priority of transmissions based on the at least one response.

Abstract: A method for enabling co-existence of multiple machines with identical addresses within a single data center network. The method includes assigning a unique pseudo identifier to each machine in the network that can be used for routing a packet to a destination machine, replacing a sender media access control address on an address resolution protocol request with a pseudo identifier of the sender at an edge network switch, retrieving a private network identifier from a mapping table based on the sender pseudo identifier and returning a pseudo identifier for the destination address based on the private network identifier, and replacing the pseudo identifier of the destination address with an actual identifier at a destination edge network switch for routing the packet to the destination machine.
