Method and system for realizing user port vlan service management in optical network unit

Abstract

The invention provides a method and system for achieving user port VLAN service management in an ONU. The method includes the steps that operation is carried out on related service hardware and logic according to VLAN service configuration data attribute tables, and the VLAN service configuration data attribute tables are saved in a first memory space of the ONU; a new table is formed according to VLAN service configuration data issued by a gateway and saved in a second memory space of the ONU; the related service hardware and logic and the VLAN service configuration data attribute tables in the first memory space are updated according to comparison results between table data in the first memory space and table data in the second memory space so as to bring service configuration into effect. By comparing new configuration and original configuration first according to the configuration data issued by network management software and then determining a next action according to marked content, user port VLAN service configuration and deletion can be efficiently achieved, VLAN service configuration states can be tracked comprehensively, specific requirements for hardware forms are avoided, and the method can be simplified and is short in implementation cycle.

Description

technical field [0001] The present invention relates to the realization of the two-layer data flow VLAN tag (Virtual Local Area Network, virtual local area network) processing function in the PON (Passive Optical Network, passive optical network) ONU (OpticalNetwork Unit, optical network unit) system, the two-layer data The flow VLAN tag processing function means that in the ONU system, its data flow engine determines whether to perform VLAN tag processing on the user's uplink and downlink messages. The ONU VLAN tag processing objects include IEEE (Institute of Electrical and Electronics Engineers) 802.1Q defined CVLAN ( CustomerVLAN, user private network VLAN tag) and IEEE 802.1ad QinQ (also known as Stacked VLAN or Double VLAN, which refers to encapsulating the user private network VLAN tag net VLAN tag). Background technique [0002] Currently, PON ONUs include EPON (Ethernet Passive Optical Network, Ethernet Passive Optical Network) and GPON (Gigabit-Capable Passive Opt...

AI Technical Summary

Problems solved by technology

[0009] The technical problem to be solved by the present invention is: for most of the current VLAN business management methods, the typical all-delete and all-build management method is adopted, thereby increasing the number of times the system operates hardware entries, which may cause the interruption of user service flow, and cannot effectively Track the service configuration status of the user port
