Abstract:
1. A mobile Ethernet system, comprising: an Ethernet home agent device, E-HA, adapted for sending an Ethernet frame, sent by a corresponding node, CN, to a mobile node, MN, to an Ethernet foreign agent device, E-FA, performing Ethernet tunnel package to a resolution of the Ethernet frame sent by the E-FA via Ethernet tunnel and sending the packaged Ethernet frame to the CN; binding an 802 Media Access Control, MAC, home address, E-HoA, and an 802 MAC care of address, E-CoA, of the MN according to a received registration request message and returning a registration response message; unbinding the E-HoA and the E-CoA of the MN according to a received deregistration request message and returning a deregistration response message; the Ethernet foreign agent device, E-FA, adapted for sending an Ethernet frame, sent by a mobile node, MN, to a corresponding node, CN, to the Ethernet home agent device, E-HA, performing Ethernet tunnel package to a resolution of the Ethernet frame sent by the E-HA via Ethernet tunnel and sending the packaged Ethernet frame to the MN; relaying a registration request message carrying the E-HoA and the E-CoA of the MN to the E-HA, and relaying a registration response message returned by the E-HA to the MN; the mobile node, MN, adapted for performing data transmission with a CN through the E-HA and the E-FA via Ethernet tunnel; sending to the E-FA a registration request message containing the E-HoA and the CoA of the MN when the MN moves to an Ethernet foreign link or mobile Ethernet foreign domain not containing an E-HA or E-FA to which the MN previously belonged; sending to the E-HA a deregistration request message carrying the E-HoA and the E-CoA when the MN moves to an Ethernet home link or mobile Ethernet home domain from an Ethernet foreign link or mobile Ethernet foreign domain; wherein each mobile Ethernet domain in the mobile Ethernet system is assigned with a mobile Ethernet identification; mobile Ethernet identifications of adjacent mobile Ethernet domains are different from each other; each E-FA and E-HA belonging to a same mobile Ethernet domain are configured with a same mobile Ethernet identification; the mobile Ethernet identification is configured in a virtual local area network, VLAN, domain or a source virtual 802 MAC address domain in an Ethernet frame; wherein when each mobile Ethernet foreign domain is assigned with a mobile Ethernet identification, each mobile Ethernet foreign domain contains at least one E-FA and Ethernet foreign link, each E-FA corresponds to at least one Ethernet foreign link; and wherein when each mobile Ethernet foreign domain is not assigned with the mobile Ethernet identification, each mobile Ethernet foreign domain contains one E-FA and Ethernet foreign link, each E-FA corresponds to one Ethernet foreign link.
