Abstract: A node in a distributed network computes a hash of content for a service received in a data packet. The node verifies the data packet by comparing the hash of the content of a service received from a neighboring node to a hash of the content computed by the node. An amount of content of the service having a same identification is accumulated in a trusted execution environment (TEE) of the node, and a signature based on code stored in a TEE of the node is generated. The node then sends the data packet to the next neighboring node, where the service-related information includes the service ID, a hash of the service content and the signature. The service records with the accumulated amount of service content, accumulated hash values, and nodes' signatures are sent to the validation nodes to reach consensus for the service provided.

Abstract: This application provides an optical link fault identification method, and relate to the field of communications technologies. The method includes: obtaining performance data of a network device, extracting a feature parameter of the performance data, and identifying a fault mode on an optical link based on the feature parameter. The method resolves problems of a difficulty in fault identification and slow troubleshooting that are caused by a large quantity of devices, many line faults, and a difficulty in obtaining manual troubleshooting cases. In addition, a fault can be quickly identified when the fault occurs, improving troubleshooting efficiency. When an optical link risk does not cause a fault, deterioration of the performance data can be found in advance based on a feature, to perform identification and warning.

Abstract: The present technology discloses a frameless modular multi-functional electronic device. The electronic device includes a base module with a processor and multiple component modules, at least one of which is configured to connect directly in contact with the base module. The modules each include a connecting member to slidably align and mate the component modules together, and an electrical interface to transmit digital information and energy between connected base and component modules. The component modules are interchangeably connected directly in contact with each other and, when assembled, form the frameless modular multi-functional electronic device.

Abstract: The present technology discloses storing data in a peer-to-peer network. A first computing device identifies other computing devices in the peer-to-peer network. Each of the computing devices have an established social relationship with at least another one of the computing devices. A degree of connection between the first computing device and each of the other computing devices is detected. A group of the other of computing devices is selected based on the degree of connection for storing the data, and a storage trust level is assigned to each of the other computing devices in the group. The storage trust level of each of the other computing devices is based on the established social relationship. The data is then transmitted to each of the other computing devices in the group for storage.

Abstract: Techniques are presented to improve the security of operation for autonomously driving automobiles and other transportation or robotic equipment with varying degrees of autonomous operation. This can include an end-to-end closed-system support of control sensors' own signal emission and self-controlled frequency or polarization, which can be hard to decipher by external attackers. The control systems can employ majority voting by multiple perception results from both time (e.g., samples from same polarization in time series of an epoch, given the fact of oversampling) and space (e.g., different polarizations or sensor types) domains for enhanced security.

Abstract: A computer implemented method for self-learning of a control system. The method includes creating an initial knowledge base. The method learns first principles using the knowledge base. The method creates initial control commands derived from the knowledge base. The method generates constraints for the control commands. The method performs constrained reinforcement learning by executing the control commands with the constraints and observing feedback to improve the control commands. The method enriches the knowledge base based on the feedback.

Abstract: The present invention relates to a base station, a small cell, and a method for scheduling a communications link resources. A first small cell reports load information and channel state information of a channel between the first small cell and a neighboring second small cell to a base station. The first small cell receives link pre-scheduling signaling from the base station. The link pre-scheduling signaling includes wireless resource occupation information that indicates an occupancy of a wireless resource of the first small cell by a backhaul link. The first small cell allocates a first wireless resource in available wireless resources to the backhaul link according to the channel state information and the wireless resource occupation information, and allocates a second wireless resource in the remaining available wireless resources to an access link used for data transmission between the first small cell and a user equipment device.

Abstract: An uplink synchronization method and a terminal are disclosed, where implementation of the terminal is as follows: a supporting terminal sends the reference signal by using a access identifier of a benefited terminal, and receives a adjustment value of synchronization information of the supporting terminal, so that uplink synchronization is implemented. The supporting terminal does not need to access a network, and therefore interference caused by the supporting terminal to another terminal and the benefited terminal on an access device side is avoided, and a preamble signal resource is reduced.
