Description
Technical field
The present invention relates to a kind of apparatus and method for realizing M-VLAN, more M-VLAN are realized more particularly to a kind of
Rack OLT device, and its method for realizing using rack OLT device more M-VLAN.
Background technology
In data communication network now, the demand of video traffic is ubiquitous, due to the data traffic of video traffic
Very big, multicast is as a kind of point-to-multipoint, i.e., single-point sends multipoint reception or multiple spot sends multipoint reception, efficient data propagate
Technology, because it can effectively reduce network load, saving network bandwidth, so being had a wide range of applications in video traffic.
Operator opens multicast services using local side apparatus, and for different access business, operator considers to use different VLAN
(Virtual Local Area Network) makes a distinction.
At present, in general access network equipment can regard the equipment of only one aspect, multicast as an entirety
VLAN realization is exactly to be realized in this one-level aspect.Under normal circumstances, two layers of OLT (Optical as access network
Line Terminal) equipment, typically it is made up of a main control card and multiple business line cards.Line card typically carries out datum plane
Data transmission disposal, main control card typically carry out the processing of protocol control plane, i.e. main control card protocol module needs to handle per bracing cable
The protocol massages of card.And when equipment it is feature-rich after, main control card needs more protocol modules to go to support, this is also tended to
Main control card is caused performance issue occur.
For the multicast functionality of standard, typically it is only provided in same VLAN and multicast traffic stream is replicated with being turned
Hair, i.e. single multicast VLAN.In single multicast VLAN system, any group address all only in groups in only one VLAN, this
Comparatively sample main control card loads smaller when multicast protocol is run.But in the mistake for actually opening multicast service operation
Cheng Zhong, single multicast VLAN just obviously can not meet operator and the different video traffics for accessing business distinguished using different VLAN
It is required that.Therefore, in order to solve this problem well, more multicast vlan technologys are arisen at the historic moment.Using more multicast vlan technologys,
Operator divides the different access business of development video traffic using different M-VLAN.In more M-VLAN systems, pin
To different group address, in groups in different M-VLAN.So require it is multigroup broadcast VLAN protocol modules, received often at it
One come from user side multicast protocol message when, be required for carry out group address judgement, then looked for according to group address
Carried out in groups to its corresponding M-VLAN.This certainly will add the negative of main control card in the realization of more M-VLAN systems
Load.And because the number of users of the OLT device terminal of access network is huge, after more M-VLAN video traffics are opened, multicast association
The amount for discussing message is also very huge, may also can so bring the performance issue of equipment.

Processing for multicast service, according to the relevant criterion of China Telecom, in protocol processes, multicast protocol module is not
It is concerned about the VLAN entrained by the protocol massages that terminal ONU (Optical Network Unit) equipment sends over, multicast protocol
Module is only concerned the group address in multicast protocol message, then with this group address in correct M-VLAN in groups.For
For single multicast VLAN system, because whole system only exists a M-VLAN, any one group address all stamps this
VLAN cans.But for supporting the system of more M-VLAN so to handle, system can permit a moment
Many individual M-VLAN exist simultaneously.This has just had more a process that its corresponding M-VLAN is found according to group address.
When there is substantial amounts of user to access, it is exactly that the multicasts of all line cards is assisted that the multicast protocol module of master control is to be dealt with
Message is discussed, would is that huge this when of multicast protocol message amount.For each protocol massages, lookup system will be carried out
The operation of system M-VLAN, this process searched frequently, can certainly will so add the burden of main control card.One kind of the present invention

224.1.1.10, the Report messages that VLAN Tag (virtual local area network tags) are 123 " are conveyed directly to exchange chip 122；
S33：Exchange chip 122 will " group address 224.1.1.10, VLAN Tag (virtual local area network tags) be 123 "
Report messages are sent to line card multicast protocol module 121 to realize multicast functionality：The configuration information of oneself is first looked for, is found
M-VLAN corresponding to 224.1.1.10 is 1000；Line card multicast protocol module 121 oneself is with VLAN1000 and group address
224.1.1.10 in groups；Then by ONU it is original " VLAN123, group address 224.1.1.10 " the first multicast protocol message turn
Change " VLAN1000, group address 224.1.1.10 " the second multicast protocol messages into；
S34：Line card multicast protocol module 121 is by " VLAN1000, group address 224.1.1.10 " the second multicast protocol messages
Exchange chip 122 is sent back again；
S35：Exchange chip 122 will " VLAN1000, group address 224.1.1.10 " the second multicast protocol messages be sent to master control
Card 11 goes to handle；
S36：The second multicast protocol message that main control card 11 receives is already provided with correct M-VLAN, so working as master control
Multicast protocol module 111 receive " after VLAN1000, group address 224.1.1.10 " the second multicast protocol messages, from " VLAN1000,
Outside VLAN and group address are extracted in group address 224.1.1.10 " the second multicast protocol messages；Then to group address
224.1.1.10 directly with VLAN1000 in groups；Last master control multicast protocol module 111 carries out relevant treatment and is grouped into the 3rd
Multicast protocol message is sent to network side.
