摘要： According to an example, to load balance a group of servers, a service access request message is sent by a client terminal and is received at a load balancing device, wherein a source Internet Protocol address of the request message is an Internet Protocol address of the client terminal of a first protocol version. A server is selected from the group of servers to send the request message. A determination is made as to whether the first protocol version is same as a second protocol version of an IP address of the selected server. If the versions are the same, the request message is sent to the selected server. Otherwise, network address translation is performed to replace the source Internet Protocol address of the request message with an Internet Protocol address of the second protocol version to send the request message.

摘要： The present invention relates to a method for accurately detecting oscillations and improving stability of power systems. The method includes the steps of providing a phase-locked loop having a phase detector, a loop filter, and a number-controlled oscillator. The method further includes the steps of extracting an input signal from the power system, using the phase-locked loop to track the frequency and phase of a targeted mode in the input signal, and creating a locally generated reference signal to fit the input signal and to allow the input signal's modal information to be obtained. The method further includes the step of performing mode shape analysis utilizing the reference phase signals constructed from the tracked frequencies.

摘要： A technique for operating a wireless communications system that supports multi-user multiple-input multiple-output (MU-MIMO) communications between a base station and multiple mobile stations involves generating inter-cell interference information at the mobile stations and providing the inter-cell interference information to the base station. The base station uses the inter-cell interference information to calculate channel quality indicators (CQIs) and then makes scheduling decisions in response to the CQIs. Data is transmitted from the base station to the mobile stations according to the scheduling decisions.
