Abstract:
1. An access device, comprising: a subscriber interface functional module; a main control switching functional module; and a Multi-Protocol Label Switching (MPLS) connection management functional module for establishing a label connection needed for a service transmission of the access device and for using, controlling, and releasing the label connection during the service transmission, wherein the MPLS connection management functional module comprises: an internal MPLS connection resource management module configured to manage internal connection resources between the subscriber interface functional module and the main control switching functional module, wherein the internal MPLS connection resource management module is configured in the main control switching functional module; an MPLS control management module configured to establish an internal label connection between the subscriber interface functional module and the main control switching functional module according to internal connection resource information sent from the internal MPLS connection resource management module, and establish an external label connection between the access device and a network side; and an MPLS service processing module configured to map a service sent from a user terminal to the internal label connection when the service is transmitted to the subscriber interface functional module, and perform a label switching process between the internal label connection and the external label connection when the service mapped to the internal label connection is transmitted to the main control switching functional module, wherein the internal label connection and the external label connection are both MPLS connections; and wherein the internal MPLS connection resource management module and the MPLS control management module are configured in the main control switching functional module of the access device, and a distributed MPLS connection configuration module and a distributed MPLS service processing module are configured distributedly in the subscriber interface functional module, wherein:
