Abstract:
1. A communication proxy method, comprising: receiving, by a communication proxy device, a packet communicated between a provider device and an access device; converting: a) a physical port of the access device in the received layer 2 control protocol, L2CP, packet to the logic port used in the provider device or converting the logic port used in the provider device in the received L2CP, Dynamic Host Configuration Protocol, DHCP, or PPP over Ethernet, PPPoE, packet to the physical port of the access device according to a preset mapping information between a physical port of the access device and a logic port used in the provider device; and b) a physical port of the access device in the received Dynamic Host Configuration Protocol, DHCP, packet to the logic port used in the provider device or converting the logic port used in the provider device in the received DHCP packet to the physical port of the access device according to a preset mapping information between a physical port of the access device and a logic port used in the provider device; or c) a physical port of the access device in the received PPP over Ethernet, PPPoE, packet to the logic port used in the provider device or converting the logic port used in the provider device in the received PPPoE packet to the physical port of the access device according to a preset mapping information between a physical port of the access device and a logic port used in the provider device; and sending the packet after the converting; wherein, the mapping information comprises a physical port ID of the physical port and a logic port ID of the logic port, and in a Digital Subscriber Line, DSL, system, the physical port ID comprises at least one of an actual access node ID, a chassis ID, a rack ID, a frame ID, a slot ID, a sub-slot ID and a port ID; and the logic port ID is Arabic numerals arranged in sequence, or at least one of a virtual access node ID, a virtual chassis ID, a virtual rack ID, a virtual frame ID, a virtual slot ID, a virtual sub-slot ID and a virtual port ID, or a character string; in a Passive Optical Network, PON, system, the physical port ID comprises at least one of the actual access node ID, the chassis ID, the rack ID, the frame ID, the slot ID, the sub-slot ID, a PON interface ID, an optical network unit ID, a Transmission container ID, T-CONT ID and a port ID; and the logic port ID is Arabic numerals arranged in sequence, or at least one of virtual access network ID, a virtual chassis ID, a virtual rack ID, a virtual frame ID, a virtual slot ID, a virtual sub-slot ID, a virtual PON interface ID, a virtual optical network unit ID, a virtual T-CONT ID and a virtual port ID or a character string; and in a wireless access system, the physical port ID comprises at least one of the actual access network ID, the chassis ID, the rack ID, the frame ID, the slot ID, the sub-slot ID, a remote radio unit ID, RRUID, a sector ID, a frequency point ID, a channel ID, a service flow ID, SFID, and connection ID, CID; and the logic port ID is Arabic numerals arranged in sequence, or at least one of a virtual access network ID, a virtual chassis ID, a virtual rack ID, a virtual frame ID, a virtual slot ID, a virtual sub-slot ID, a virtual RRUID, a virtual sector ID, a virtual frequency point ID, a virtual channel ID, a virtual SFID and CID, or a character string.
