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

Embodiment Construction

[0064] The present invention will be described in detail below in conjunction with the drawings.

[0065] Such as figure 1 As shown, the present invention is mainly applicable to a PON system, which is composed of an optical line terminal OLT (Optical Line Terminal) at the central office, an optical network unit ONU (Optical Network Unit) at the user end, and an optical distribution network (ODN). The method for realizing user port VLAN service management in the optical network unit provided by the present invention is mainly to provide an effective user port VLAN service management method for ONU, thereby reducing hardware and logic operations and ensuring the fluency of service data flow , Effectively track the service configuration status of the user port.

[0066] Such as Figure 4 As shown, the user port VLAN service management method of the present invention includes the following steps:

[0067] Step 200: Define the service type, record the type of each service and the number...

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 a VLAN tag (Virtual Local Area Network, virtual local area network) processing function of a Layer 2 data stream in a PON (Passive Optical Network) ONU (Optical Network Unit) system. The data flow VLAN tag processing function means that in the ONU system, the data flow engine decides whether to perform VLAN tag processing on the user's upstream and downstream messages. The ONU VLAN tag processing object includes the CVLAN defined by IEEE (Institute of Electrical and Electronics Engineers) 802.1Q (Customer VLAN, user private network VLAN tag) and IEEE802.1ad QinQ (also known as Stacked VLAN or Double VLAN, refers to the user private network VLAN tag encapsulated in the carrier public network VLAN tag) introduced SVLAN (Service Provider VLAN, Carrier public network VLAN tag). Background technique [0002] Currently, PON ONUs include EPON (Ethernet Passive Optical Network) and GPON (Gigabit-Capable Passive O...
