Layer 2 data and the analysis of three layer datas, the acquisition Layer 2 data table corresponding with the data flow and three layer datas are carried out according to stream
Table, QINQ tables are generated according to the Layer 2 data table of acquisition and three layer data tables, according to the QINQ patterns being pre-selected and relatively
The configuration parameter answered, will need the value corresponding to the field of matching to be delivered in register in QINQ tables, meanwhile, positioning searching is pre-
In configuration processing function corresponding to the QINQ patterns first selected, the configuration processing function pair register arrived by positioning searching
Need the value corresponding to the field of matching to carry out rule match, the match is successful, then the data flow corresponding to QINQ tables is performed outer
Layer QINQ labels SVID mark, and the data flow after mark is delivered into corresponding port, output of queuing up is set so as to realize in OLT
Standby upper configuration QINQVLAN, carries out outer layer QINQ labels SVID mark from the ONU data flows received to OLT, improves
The processing speed of QINQ messages, in EPON+EOC networks, carries out inner VLAN tag identifier, in OLT on the port of EOC terminal
The upper mark for carrying out outer layer QINQ labels SVID, because broadcast traffic can only be transmitted in identical vlan number, so this set
The network configuration for optimizing EPON+EOC systems further, greatly reduces the transmission range of broadcast traffic, reduces nothing
The appearance of traffic situation is imitated, user's networking speed is improved.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
Any modifications, equivalent substitutions and improvements made within refreshing and principle etc., should be included in the scope of the protection.
