Method for supporting asymmetrie digital subscriber line access in embedded operating system

A method for supporting non-symmetry digital user line circuit access in an embedded operating system, comprising, starting establishing dialogue process through PPPoE protocol depot, completing address finding stage, the server setting up connection for the user, and assigning an IP address for the user through dynamic allocation, using the IP address to achieve dynamic bonding with the networking protocol depot module, the data conference creating stage, wherein the original IP data pack passing through the PPP protocol depot and PPPoE protocol depot, proceeding packing and re-framing on the dispatching party, removing the remaining IP data by the packet header step-by-step on the receiving party. The invention can fully utilize the network resource of the broad band business and conserve the line expenditure. ii
