Problems solved by technology

[0012] Among the existing technologies, the disadvantage of the static configuration method is that it is too cumbersome to configure, and it cannot guarantee that the data flow on the network side can be classified according to the rules of the static configuration, and it is also not suitable for the actual application scenarios of dynamic changes; The disadvantage of the port method is that the design is complex and the hardware cost is expensive. At present, there are few corresponding Ethernet switching chips to support it; Super VLAN requires Ethernet switching chips to support Layer 3 functions
From the analysis of these three methods, there is no simple, effective and low-cost VLANID N: 1 convergence conversion method.

Embodiment Construction

[0085] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0086] image 3 It is a schematic diagram of the hardware structure of the MDU-type ONU used to realize the convergence and conversion of the VLAN ID involved in the present invention. The ONU includes three hardware modules: an Ethernet switch chip, a CPU and an EPON chip. The uplink port of the Ethernet switch chip is connected to the Ethernet side interface of the EPON chip, the management control interface of the Ethernet switch chip is connected to the CPU, and user ports 1 to 16 are respectively connected to the home gateway. It should be noted that the present invention In order to describe the technical solution clearly and completely, the text uses an ONU with 16 user ports as an example. The specific number of user ports is not necessarily 16. The number of user ports of different MDU-type ONUs is different. Applying the method described in the pre...

Abstract

The invention provides a solution to VLAN ID convergence conversion, which relates to VLAN ID conversion of MDU-type ONU providing Ethernet interfaces in EPON systems. The solution is characterized by comprising the following: step 1, performing power-up initialization; step 2, updating and analyzing VLAN ID conversion configuration tables to determine a VLAN ID conversion mode; and step 3, performing convergence conversion on downlink unicast messages and broadcast messages according to the result of analyzing the VLAN ID conversion configuration tables. The solution has the advantages that the solution can simply and conveniently restore VLAN ID on the same network side in a downlink direction to a plurality of VLAN IDs on different user sides, gives a conversion solution to the VLAN ID of data stream of which the target MAC address in a downlink part is broadcast, and is low in demand for hardware, simple to implement, short in development cycle and low in cost.

Description

technical field [0001] The present invention relates to the VLANID (Virtual Local Area Network Identifier, virtual local area network identifier) ​​conversion of the MDU type ONU that provides Ethernet interface in the EPON system, said MDU type ONU especially refers to the MDU type with a plurality of Ethernet interfaces on the user side ONU, specifically, is a solution to VLAN ID convergence conversion. Background technique [0002] The Ethernet-based EPON system (Ethernet Passive Optical System, Ethernet Passive Optical Network) is a single-fiber bidirectional optical access network with a point-to-multipoint structure. services, and provide up to 1Gbit / s uplink and downlink bandwidth for end users. The EPON system consists of an OLT (Optical Line Terminal) on the office side, an ONU (Optical Network Unit) on the user side, and an ODN (Optical Distribution Network) on the user side. According to the application scenarios of the current EPON equipment, the optical networ...
