Network unit) directly it is connected with subscriber terminal equipment, provide PC (Personal Computer, personal computer) to end user
Online, VoIP (Voice Over Internet Protocol, the networking telephone) voices and IPTV (Internet Protocol
Television, network protocol television) multiple business such as Set Top Box.
Because PC businesss of networking, VoIP speech businesses and IPTV set top box business (hereinafter referred to as three kinds business) are belonging respectively to
Different Virtual network operators, thus the upstream of three kinds of business from the PON mouths of ONU go out when, need to take respectively and the business
VLAN (Virtual Local Area Network, the VLAN) marks of map network operator.Due to PC online,
The message that VoIP voices, the user terminal of IPTV set top box send and receive is general all without the untag of VLAN tag (label)
Message, therefore ONU needs are according to certain logic rules, respectively by the upstream of three kinds of business plus corresponding with current business
VLAN is identified and sent to network in the way of tag messages.
At present, industry generally using following two methods by the upstream of three kinds of business respectively plus corresponding VLAN and
Network is sent in the way of tag messages.
(1) traffic differentiation based on port.
Because the different user port essence of ONU is exactly the different port that correspondence is exchanged, therefore ONU different ports can
It is configured to different VLAN and binds corresponding business for each VLAN；A kind of business of binding is fixed in each port of ONU
(PC businesss of networking, VoIP speech businesses or IPTV set top box business), multiple ports of ONU binding different business cooperate reality
Existing various mixed services.PC businesss of networking and VoIP business both can also adopt route pattern, IPTV using bridge mode

The VLAN tag for carrying are sent to network.ONU by different VLAN tag distinguish PC business of networking streams, VoIP Business Streams or
IPTV set top box Business Stream；After ONU differentiated service streams, transparent transmission process is carried out to band tag messages or translation is processed.
But, when above two method is used, it is respectively present following defect：
(1) for the method for " traffic differentiation based on port ", ONU must be equipped with multiple user ports；It is existing
Most of ONU normally only equipped with 1 user port, the ONU of unique user port can only use a kind of business, it is impossible to while
Using three kinds of business.Therefore the method for " traffic differentiation based on port " can only make on the ONU equipped with multiple user ports
With its scope of application is relatively simple, is not easy to people and uses.
(2) for the method for " traffic differentiation based on port ", user is same on the ONU with multiple user ports
When using three kinds of business when, need to carry out different configurations in advance according to the operator of different business and by PC, VoIP voice and
IPTV set top box inserts corresponding user port, if wrong plug user port, can not carry out the business then, and difference is carried out in advance
Configuration and insert multiple user ports operating process it is more complicated, be not easy to people and use.
(3) for the method for " traffic differentiation based on VLAN ", VoIP speech businesses and IPTV set top box business are sent out
The message for send, receiving is necessary for tag messages；Therefore, " based on VLAN traffic differentiation " method may be only available for send and
Receive VoIP speech businesses or the IPTV set top box business of tag messages, it is impossible to the VoIP suitable for sending and receiving untag messages
Speech business or IPTV set top box business.For Most current send and receive the VoIP speech businesses of untag messages or
For IPTV set top box business, the scope of application of the method for " traffic differentiation based on VLAN " is relatively simple, and being not easy to people makes
With.
