  • Method of transmitting data with redundant structure, and device for transmitting data by said method
    Patent number: 7463655
    Abstract: The present invention provides a data transmission method in which a SONET is applied to Ethernet LANs. This method realizes a redundant structure of the Ethernet while utilizing the bandwidth of the SONET. On a server side, a working path and a back-up path of the Ethernet are multiplexed onto the same path of the SONET, and data transmission is conducted through the multiplexed path. On a client side, a data packet transmitted through the multiplexed path is divided by a filtering operation through detection of a port ID added on the transmitting side.
