Abstract: A network controller for delay measurement in SDN and related delay measurement system and delay measurement method are provided. A probe packet is used to record the transmission of the probe packet between the network controller and network switches, to calculate a transport delay time between the network switches and hop delay time between the network switches, to obtain the delay of each link in the transmission path, which helps in finding out a critical hop in the SDN transmission path. Through the delay measurement mechanism according to the present disclosure, the critical hop will become a reference based on which a network manager adjusts a network framework, or a basis taken by an SDN control system to select a path.

Abstract: A method for live migration of a virtual machine in a MR-IOV environment is provided. The method is used in a system, wherein the system includes a plurality of computing hosts, an MR-IOV device, and a management host including a physical function and configured to implement a plurality of virtual functions. Eand each computing host and the management host are coupled to the MR-IOV device. The method includes: migrating, by a source computing host of the computing hosts, a source virtual machine in the source computing host to a destination VM in a destination computing host of the computing hosts, wherein the source VM includes a source VF; transmitting, by the destination computing host, a request message to a management host and reassigning, by the management host, a first VF corresponding to the source VF in the management host to the destination VM according to the request message.

Abstract: A tree recovery method for a software-defined network (SDN) adapted to an SDN controller is provided. The tree recovery method includes: establishing topology information based on a current SDN topology and storing the topology information in a storage of the SDN controller; receiving a failure message reporting a failure link of the SDN, a plurality of network nodes of the topology information are classified into at least one losing nodes and at least one remaining node according to the failure link; and calculating and linking the at least one losing node to the at least one remaining node by using the topology information stored in the storage.

Abstract: The present disclosure provides a data storage method, a data storage system and a requesting node. The data storage method includes the following steps. A register identifier and a register time are written into a target data table. The target data table is read to look for a register time record, such that an access right of the storage node is determined. A requesting node having the access right computes result data, and writes a usage identifier and the result data in the target data table. The target data table is read to judge the validity of the result data.
