Abstract:
1. A method for improving subscriber access capacity of a broadband access device comprising a plurality of access ports, comprising: establishing at least one Virtual Local Area Network Path Identifier (VlanPI) and corresponding VlanPI Tag; establishing one VLAN Circuit Identifier (VlanCI) and one corresponding VlanCI Tag for each of the plurality of access ports of the broadband access device; dividing the plurality of access ports into groups and assigning the established VlanPI to each group, wherein one VlanPI Tag and one VlanCI Tag are established to be combined to identify one of the plurality of access ports and to be inserted into at least one ethernet frame, different groups correspond to different VlanPI Tags, and a VlanCI corresponding to a first group of the groups can be identical with a VlanCI corresponding to a second group of the groups, wherein the broadband access device comprises multiple network switching chips, and the step of dividing the plurality of access ports into groups comprises: categorizing access ports belonging to each network switching chip into one group which corresponds to one Vlan PI; determining a VlanCI which corresponds to an access port, inserting the VlanCI Tag for identifying the VlanCI into an ethernet frame; determining a VlanPI corresponding to a group to which the access port belongs, inserting a VlanPI Tag for identifying the VlanPI into the ethernet frame; and transmitting the ethernet frame tagged with the VlanCI Tag and the VlanPI Tag to an uplink device through an uplink port by the broadband access device which connects with the uplink device.
