A multi-terminal interaction relation maintenance system and method, the interaction relation is states of performing instruction and data synchronization interaction by a plurality of terminals in the same service instance in a traffic service system. The system comprises an interaction service module and an interaction terminal. Terminals that have an interaction relation belong to the same bounding group, terminals in the same bounding group are served by the same service instance, the interaction service module manages the bounding group based on rules, comprising but not limited to creating, modifying and deleting the bounding group, provides a mutual addressing service for the terminals in the bounding group and also provides a service for a terminal to be bound or unbound with other terminals, and after mutually addressing by means of the interaction service module, terminals interact with each other by means of instruction and data interaction.

The present invention can perform efficient data processing by sharing computing resources with other vehicles through steps of monitoring a state of connection with a first server, determining whether the state of connection with the first server is a delay occurrence state, and transmitting a message for searching for a second vehicle in order to form a P2P group for computing resource sharing. One or more of an autonomous vehicle, a user terminal and a server of the present invention can be associated with an artificial intelligence module, an unmanned aerial vehicle (UAV) robot, an augmented reality (AR) device, a virtual reality (VR) device and a 5G service related device.

Systems and methods are provided to process an event stream using nodes arranged as a cluster in which the nodes are in a leader-follower relationship with one node being the leader at any given time. Tracking of node membership and leadership status can be conducted in a manager node for a variety of applications. Each node of the cluster can register in the manager node and can receive the same set of event streams as the other nodes of the cluster. The leader node can process an event of an event stream with the follower nodes tracking the processing by the leader node, where the leader node can publish the processed event. Leadership can be changed from the leader node to another node of the cluster based on a performance criterion of the leader node. Additional systems and methods can be implemented in a variety of applications.

Apparatus and methods for establishing a permissioned blockchain on an Internet of Things (IoT) system. The method may be performed by a central IoT hub. The method may include identifying a IoT nodes associated with the IoT system. The method may also include running an authentication routine on the identified IoT nodes. The method may further include identifying a subset of the IoT nodes that have been authenticated by the authentication routine. The method may further include grouping the subset of IoT nodes into a first group of IoT nodes and a second group of IoT nodes, the grouping being based at least in part on available storage space and processing speed of each of the subset of IoT nodes.

Data relating to at least the dynamic objects of the surrounding area is ascertained by sensors of at least one motor vehicle. The data is stored in a database provided by a motor vehicle, acting as a server for the surrounding area, which communicates with other motor vehicles. When a request message is received, the motor vehicle acting as a server transmits at least one part of environmental data in the database to the requesting motor vehicle and/or transmits a request message for transmitting environmental data, relating to the requested data about at least one object, to other motor vehicles to update the database and/or captures environmental data relating to the at least one object by other sensors. The database is updated to include the transmitted or captured environmental data.

A method and device for determining a cluster network card, and a computer readable storage medium. The method comprises: reading a network segment of a Cluster IP from a configuration file of a current node; determining the type of the network segment of the Cluster IP by means of an address string in the network segment of the Cluster IP; obtaining an IP and a network card corresponding to the type of the network segment of the Cluster IP on the current node; and calculating the network segment of each IP, determining the IP corresponding to the network segment with the same address string as a Cluster IP, and determining the network card where the IP is located as a cluster network card. According to the disclosure, the cluster network card can be automatically and accurately found according to the configuration file.

Described herein is a transient social network that exists as long as its members are physically together. Members become a part of a private social network, referred to as a Cliq, which is facilitated by the use of an application on participant's mobile devices. The Cliq instance is recorded on a server automatically, storing the place and time of the participants meeting. A meta-identity profile of the Cliq is established and content is recommended or desired content is retrieved upon request.

In one aspect, machines in a managed network implements a set of rules that cause individual machines to directly interact with only a small number of machines in the network (i.e., a local neighborhood within the network), while the independent local actions of the individual machines collectively cause the individual machines to be self-organized into one or more communication orbits without any global control or coordination by a server or an administrator. The communication orbits are used for supporting network, security and system management communications in the managed network.

A method and an apparatus for data processing are provided. Interface circuitry connects the apparatus in a distributed system. Processing circuitry generates first hash values for a first group of virtual nodes to be added into a hash ring. The first group of virtual nodes represents a first newly added device in the distributed system. Then, the processing circuitry distributes the data in the distributed system according to the hash ring that includes the first group of virtual nodes. When the distribution of the data in the distribution system fails to satisfy a uniformity requirement, the processing circuitry identifies a specific virtual node in the first group of virtual nodes that causes the distribution to fail the uniformity requirement. Then, a hash value for a makeup virtual node to replace the specific virtual node is generated to update the distribution of the data in the distributed system.

The techniques and systems described herein implement an improved peer matching service by coordinating peer matching requests across multiple peer matching nodes configured within a peer matching unit so that resource consumption can be spread out and resource limitations are not exceeded. Moreover, the peer matching service can determine if a peer matching unit is overloaded (e.g., experiencing an increased number of requests in a given time interval that is causing performance degradation), and the peer matching service can implement an action to scale out the number of requests within the peer matching unit (e.g., re-distribute some peer matching requests to another peer matching unit). In various examples, the peer matching service can determine if peer devices are co-located peer devices based on location information and can generate a list that prioritizes the co-located peer devices.
