One aspect provides a system and method for selecting a path for a data flow in a network. During operation, a first node receiving the data flow can determine flow information that specifies a destination node. The system estimates a Quality of Experience (QoE) value of each node based on the flow information and current operating status of each node. A management service generates a QoE topology of the network based on connectivity among the nodes and the QoE value associated with each node; determines a plurality of potential paths between the first node and the destination node, with each potential path comprising a plurality of intermediate nodes; and selects a path that provides best QoE performance based on the QoE topology. Selecting the path comprises computing a cumulative QoE value of each potential path based on QoE values of the intermediate nodes included in the potential path.

The present invention discloses an enhanced, self-healable or recoverable and recyclable 3D printed article and a preparation method and use thereof. By introducing a functional monomer into a 3D printing system, a self-healable or recoverable 3D printed article is prepared or the interface strength of the 3D printed article is enhanced; or by using at least one monofunctional thermoplastic photosensitive resin monomer as one of 3D printing raw materials, a recyclable 3D printed article is prepared.

Example implementations relate to managing a resource of a network device. A resource of a network device may be assigned from a first tenant to a second tenant of the network device. Resources of the network device may include an assignment right, an access right, and a configuration right, By assigning the resource to the second tenant, the second tenant may be granted an access right to the assigned resource. Responsive to the assignment of the resource, an access right to the assigned resource may be removed from the first tenant such that the first tenant is isolated from the resource.

The present disclosure discloses a full adder based on resistive-switching devices and an operation method thereof. A multi-bit full adder circuit is constituted by using a cross-bar array of resistive-switching devices, wherein data of standard sums is stored on the principle diagonal of the cross-bar array in a nonvolatile manner, and carry data is stored in adjacent units on both sides of the principle diagonal. The carry data is stored according to whether the storage loop (crosstalk loop) is turned on. With the present disclosure, the multi-bit full adder circuit is significantly simplified. Thereby, additional circuits for generating a carry signal are reduced, the circuit delay and chip area are decreased, and the adder has an ability of nonvolatile storage.
