  • Method for measuring network throughput
    Patent number: 9749210
    Abstract: A method for measuring network throughput is provided. The method comprises the following steps: exchanging messages with a time synchronization protocol server in compliance with a time synchronization protocol, synchronizing a slave clock with a master clock of the time synchronization protocol server according to time information related to the messages, and calculating at least one network throughput according to the time information and size information related to the messages.

  • Network device, IPsec system and method for establishing IPsec tunnel using the same
    Patent number: 9602470
    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.
