Abstract: A method of implementing a computing service on edge nodes of a communication network, where the computing service is made from a plurality of service functions, each of which is connected to another service function by a communication routine. Service functions and routines can be deployed on edge nodes and communication between any two service functions can be performed via a routine and a privacy router, with coordination from a routine manager. Service functions and routines can be grouped into tasks, which can be coordinated with task managers. Tasks can be grouped into works, which can be coordinated with work managers. Because a privacy router can perform encryption on routine communications, any of the entities implementing the computing service can be deployed on edge nodes of a communication network, and a service manager can interface with external entities.

Abstract: Embodiments of this application provide a central unit, a remote unit, a small cell system, and a communication method. A digital-to-analog conversion (DAC) module and an analog-to-digital conversion (ADC) module are disposed in the central unit, so that the central unit transmits an analog optical signal to the remote unit. When the central unit transmits the analog optical signal to a plurality of remote units, because a processing delay of an analog component in analog transmission is usually at a nanosecond level, and a total delay formed by a path transmission delay and the processing delay fluctuates slightly or even is fixed, synchronization of the plurality of remote units can be easily implemented in the central unit through calibration. Therefore, it is possible to easily implement a distributed MIMO function.

Abstract: A networked data analytics management (DAM) system includes a data representation manager (DRM), a data collection and preprocessor (DCP), a correlation manager (CM) and a data source discoverer (DSD). The DRM obtains representations of data sources, used to represent data source characteristic. The DCP interacts with the data sources to obtain data via data collection actions. The CM determines correlations between different obtainable data, based on the representations. The DSD interacts with a data consumer and the CM to determine the set of data collection actions to perform, and to configure the DCP.

Abstract: Embodiments of this application disclose a data transmission method and a communication apparatus. The method may be applied to a data transmission or data distribution scenario in a peer-to-peer P2P network. The method includes: A first end node sends delayed transmission information to a second end node, where the delayed transmission information indicates time information at which the first end node delays sending first data to the second end node. When determining that the second end node accepts the delayed transmission information, the first end node delays sending the first data to the second end node, to alleviate a load of the first end node, so that a network congestion problem caused by a large-scale concurrent data request can be resolved.
