Abstract: A method for filtering web page content is disclosed in this invention. In the method, a web page request to obtain a web page from a web server is received from a client through a network equipment after the client builds a connection with the web server. The network equipment transmits the web page request to a cloud server for determining if the web page needs to be blocked according to the web page request. A first disconnection request and a second disconnection request is generated according to the web page request if it is determined that the web page needs to be blocked. The first disconnection request is transmitted to the client and the second disconnection request is transmitted to the web server through the network equipment. Subsequently, the connection between the client and the web server is disconnected.

Abstract: A discrete loading algorithm maximizes data rate or system performance margin for discrete multitone (DMT) transmission. A preliminary bit assignment for each subchannel is first obtained by optimizing a DMT system with an available bandwidth. The subchannels that receive negative bit assignments are then excluded for further optimization until all the bit assignments are positive. The bit assignment of each subchannel is rounded and a corresponding rounding error is calculated. If the total bit number of the bit assignments are greater than the available bandwidth, the bit assignment of the subchannel having the least rounding error is decreased by one bit. If the total bit number of the bit assignments are smaller than the available bandwidth, the bit assignment of the subchannel having the largest rounding error is increased by one bit.
