  • Manufacture and method for accelerating network address translation
    Patent number: 7561585
    Abstract: The speed of the network address translation translated with software is generally slower than the speed of transmitting packet in the network, so that the data stored in memory is affected. In this invention, the network address translation is translated by hardware, and a plurality of comparing engines is employed to accelerate the translating speed. Therefore, even in the worst case scenario, the time needed for translating the network address is shorter than the time needed for storing the packet into memory, so that the operation of the network address translation is assured not to affect the data transmission in the network.
