  • Publication number: 20140351590
    Abstract: A network device is provided. The network device is connected to a number of slave network devices. Each slave network device communicates with the network device by using an Internet protocol (IP) address. The network device includes an Internet protocol security (IPsec) module and a network address translation (NAT) module. The IPsec module establishes an IPsec tunnel to a network gateway in the Internet and retrieves an IPsec IP address corresponding to the IPsec tunnel. The NAT module converts the IP addresses of the slave network devices to the IPsec IP address, such that the slave network devices use the IPsec IP address to communicate with the network gateway through the IPsec tunnel.

  • Patent number: 8884209
    Abstract: A light determination circuit having a laser module and a detection circuit is provided. The detection circuit comprises a threshold voltage determination unit, a comparison unit and a switch unit. The threshold voltage determination unit determines a threshold voltage corresponding to the laser module. The comparison unit is for comparing a voltage level at a first node of the laser module with the threshold voltage to output a switch signal. The switch unit is controlled by the switch signal to switch the voltage level at an output end of the detection circuit. When the laser module is conducted, the voltage level at the first node is lower than the threshold voltage, the switch signal controls the switch unit, such that the output end outputs a high level voltage and vice versa.

  • Patent number: 8767583
    Abstract: A network resource allocating method for a residential gateway includes the following steps. A first downlink bandwidth is allocated to a residential gateway for process of a first service. A second downlink bandwidth is allocated to the residential gateway for process of a second service. A processing priority of the first service is higher than a processing priority of the second service. A first downlink rate of the residential gateway is detected when the residential gateway processes the first service. A second downlink rate of the residential gateway is detected when the residential gateway processes the second service. A bandwidth usage state of the residential gateway is determined according to the first and the second downlink rates. The second downlink bandwidth of the residential gateway is adjusted according to the bandwidth usage state such that the quality of service (QoS) of the first service or the second service is enhanced.
