    摘要: A method of carrying SDH services in PON is provided, in which tributary units carrying SDH service data are mapped into payload part of GEM frames, thereby implementing transmission of SDH services in GPON. De-capsulation is performed in reverse process at receiving end. A device of receiving or transmitting SDH services and a method of mapping SDH data frame into PON data frame are also provided. The present invention may be merged with SDH network directly since standard SDH tributary unit structure is adopted, and extraction of virtual containers that includes SDH service data and synchronism can be accomplished conveniently based on pointer adjustment mechanism adopted by tributary units.

    摘要: Systems and methods for distributed overlay multi-channel MAC for wireless ad hoc networks are described. In one aspect, the systems and methods divide channel frequencies defined by a wireless network protocol into a single home channel and multiple guest channels that are orthogonal to the home channel. Each of the network nodes in the ad hoc network operates on the home channel for respective variable and overlapping amounts of time to maintain network connectivity with other respective network nodes. Additionally, each of the network nodes determines whether and when to switch from the home channel to a particular guest channel of the guest channels for a variable amount of time to increase data throughput over one or more corresponding communication links in the ad hoc network with other network node(s).

    摘要: A switching power supply controller has a nominal loop gain and transient loop gain that is only activated in response to an abrupt load change in one direction. The transient loop gain may be implemented with a series-connected diode and resistor combination arranged in a feedback configuration with an error amplifier. A large load change in one direction may swing the output of the error amplifier and forward bias the diode to create a non-linear gain change.

    摘要: The present disclosure is related to a method for monitoring upstream burst performance in a point to multi-point access network. The method comprises: determining the expected time of the upstream data burst from the current terminal end (TE) reaching the head end (HE) using the timeslot assigned to the current TE, monitoring the actual time of the upstream data burst from the current TE reaching the HE, calculating and saving the difference between the expected time and the actual time of the upstream data burst from the current TE reaching the HE; calculating and outputting whether the difference is equal to or exceeds the TE's performance index value for the predetermined monitoring terms. The method provided by the present disclosure may monitor upstream burst performance of the entire network and discover the TEs with potential malfunctions, to effectively improve the network's stability.
