Abstract: Embodiments of the present invention disclose a data processing method including: obtaining, by a distribution server, original data, determining a target type of the original data, determining, based on the target type, a target computing server to which the original data belongs, and sending the original data of the target type by sending a data storage request to the target computing server; and receiving, by the target computing server, the data storage request sent by the distribution server, storing the original data of the target type, and each time a preset aggregation period is reached, determining aggregated data of the target type in a current aggregation period based on original data of the target type that is received in the current aggregation period. By using the present method, efficiency of data statistics processing can be improved.

Abstract: Systems and methods are provided for use of common mode rejection (CMR) for echo cancellation in uplink communications. A node in a cable network configured for transmitting downstream (DS) signals and receiving upstream (US) signals, may include echo cancelling circuits configured for cancelling echo introduced by the DS signals and/or transmittal of the DS signals, onto US signals and/or US reception path, to facilitate full-duplex (FDX) communications of the DS signals and US signal. The echo cancelling circuits may be configured for operating in the analog domain. The echo cancelling circuits may include an echo cancelling combiner configured for combining two or more upstream signals non-coherently.
