    Abstract: A migration system for migrating an application between environments is provided. The migration system includes analyzes a profile of the application on a first environment based on a conformance check. The migration system reconstructs application dependencies with respect to a second environment, based on the application profile analysis, to produce an updated environment with reconstructed application dependencies. The migration system migrates the application from the first environment to the updated environment with the reconstructed application dependencies.

    Abstract: The present invention discloses a method and apparatus for processing a data packet in a software defined network SDN protocol-based network. The method comprises: receiving a data packet forwarded by a SDN switch in the network; obtaining a rule corresponding to a data flow where the data packet is located; determining, according to the received data packet, data flow characteristics of the data flow where the data packet is located; determining timeout information of the rule according to a predetermined matching relationship between the data flow characteristics and the timeout information, the timeout information indicating time that the rule will be kept in a flow table of the SDN switch; and sending the rule and the timeout information of the rule to the SDN switch for processing the data packet by the SDN switch according to the rule. By means of the method and apparatus of the embodiments of the present invention, the timeout information of the rule may be set flexibly, so that the performance of SDN is boosted efficiently.

    Abstract: In one embodiment, a system includes a first tracked device and a second tracked device. The first tracked device includes first known device data, describing one or more previous connections known to the first tracked device. The second tracked device includes second known device data, describing one or more previous connections known to the second tracked device. The first tracked device is configured to connect to the second tracked device, transfer to the second tracked device at least a portion of the first known device data, and receive from the second tracked device at least a portion of the second known device data. The first tracked device is further configured to modify the first known device data to incorporate the second known device data. The second known device data includes data related to a previous connection involving a third tracked device outside a signal range of the first tracked device.
