摘要： A method and an apparatus for processing upstream data abnormity are provided. The method includes: an Optical Line Terminal (OLT) detecting that upstream data is abnormal, the OLT instructing one or more Optical Network Units (ONUs) to stop transmitting the upstream data and/or instructing one or more ONUs to change a physical channel. By means of stopping ONUs from transmitting upstream data and/or changing the physical channels of ONUs, the present invention solves the problem of the upstream data abnormity in the related art, thereby can avoid the impact on normal service transmission of ONUs, and ensure the quality of the network service.

摘要： Techniques, apparatus and systems are described for accommodating the optical network units (ONUs) having different nominal upstream bitrates on the same passive optical network (PON) system by making the specified burst preamble and the bandwidth map allocation record format invariant with respect to the nominal upstream bitrate of a target ONU. The disclosed techniques, apparatus and systems allow seamless evolution of the lower-bitrate services to higher-bitrate services offered to an end-user without need to upgrade the central office equipment. In addition they can avoid the adverse consequences of inadvertently connecting a high-upstream-bitrate ONU to a lower-upstream-bitrate network.

摘要： A method, a device and a system for configuring maximum standby time of wireless local area network station are disclosed. The method includes the following steps that: an access point (AP) receives an association request or a re-association request sent from a wireless local area network station (STA); the AP judges whether or not the STA supports an extended values of a standard maximum idle period according to a preset flag in the association request or the re-association request received, wherein the standard maximum idle period is the maximum idle period defined in the 802.11v; if the STA fails to support the extended values, the AP configures the maximum idle period of the STA within the standard maximum idle period; and if the STA supports the extended values, the AP configures the maximum idle period of the STA within the standard maximum idle period or the extended values of the standard maximum idle period according to an instruction from an upper layer. The present invention enables an STA needing to stand by for a long time within associated with an AP for a longer time, thus preventing the STA from frequently sending a Keep-alive frame to the AP and consequentially saving the power consumption of the STA and prolonging the service life of the battery of the STA.
