The invention provides a method and a device capable of realizing P2P flow optimization based on a local scheduling mechanism. The method comprises the following steps: a DPI system indentifies the P2P signalling of a client side, and the P2P signalling is copied and transmitted to a redirected network element and comprises a resource access request; the redirected network element returns a redirected message to the network client side, the resource access request is redirected to a local Tracker agency, and the redirected message comprises the IP address of the Tracker agency; the client side sends the resource request message applied by P2P to the local Tracker agency; the local Tracker agency optimizes a Peer listing returned to the client side; P2P users in the area are dispatched to provide request accessing resource for the client side to guide flow localization. The invention remits P2P traversing and outlet flow.
