Abstract
The invention discloses a kind of method that travelling across VLAN multicast is realized under PON system, comprise the following steps：After PON system initialization, the configuration of ONU travelling across VLAN multicasts is handed down to by OLT, ONU end receives up IGMP Report messages；ONU programs receive the IGMP Report messages of up direction, check whether message has VLAN ID；If VLAN ID, ONU search travelling across VLAN multicast forward table, otherwise abandoned；If in travelling across VLAN multicast forward table, ONU finds corresponding VLAN ID, then up IGMP Report messages is converted into corresponding VLAN ID, otherwise just directly forwarded to PON mouths.The present invention is directed to PON system, and OLT realizes travelling across VLAN multicast functionality simultaneously under IGMP Snoop and IGMP Proxy patterns.
Description
Technical field
The present invention relates to a kind of method that travelling across VLAN multicast is realized under EPON, more particularly to PON system.
Background technology
Compared with cable transmission, optical fiber transmission has the advantages such as capacity is big, loss is small, anti-electromagnetic interference capability is strong, because
And the cost transmitted with optical fiber progressively declines, the optical fiber of access network is inevitable development trend, and EPON uses
Passive device, is realize the most potential technology of broadband optical access net.
Classify from the content of carrying, PON technologies mainly include APON（ATM Based PON, asynchronous transfer mode are passive
Optical-fiber network）、EPON（Ethernet Based PON, Ethernet passive optical network）And GPON（Gigabit PON, gigabit
EPON）Deng.
As shown in figure 1, PON is typically by positioned at central office（CO）Optical line terminal（OLT）It is located at user with a series of
The ONU at end（Optical network unit, Optical Network Unit）Or ONT（ONT Optical Network Terminal, Optical Network
Termination）Form, in these devices between be the optical distribution network being made up of optical fiber, passive optical splitters or coupler
（ODN, Optical Distribution Network）.
In PON system, under IGMP Snooping modes, ONU performs IGMP Snooping functions, and OLT performs IGMP
Proxy, by the dynamic group membership management of IGMP protocol realizations of standard, mainly by IGMP Report/Leave and
Query message realizes being dynamically added/exit and maintaining for multicast member.Multicast service control of authority under which is by IPTV
Business platform realizes that IPTV platforms obtain access authority information of the user to multicast service, and foundation by the certification of set top box
Its access rights pushes different electronic program EPGs to user, and user can only access the channel correlation shown on specific EPG,
And then realize multicast access privilege control.
In such a mode, ONU is by intercepting multicast application terminal（Such as set top box）Be sent to the IGMP of multicast router into
The mode of member's report Report message, the corresponding relation of group membership and exchange interface is formed, i.e. multicast forward table, multicast turns
The forwarding-table item delivered is using Group addresses/multicast mac address as index, rather than with MVLAN+Group addresses/multicast MAC
Address is as index；The downlink multicast packet that ONU is received according to multicast forward table is transmitted to the phase with group membership
Interface is answered, the M-VLAN of ONU per-port basis carries out rough control to the multicast access rights of each uni port.
Then when realizing travelling across VLAN multicast functionality, as shown in Fig. 2 ONU descending multicast data message is carried out across
VLAN multicasts（Such as the VLAN ID of VLAN=M multicast data message are replaced with to VID=I User IP TV VLAN ID）.
OLT ends must be turned on IGMP Proxy functions, and the VLAN ID for the IGMP report messages that uplink user end is sended over turn
The VLAN ID of the multicast source are changed to, the IGMP report messages are then sent to distal end multicast source, so as to realize PON system
Under travelling across VLAN multicast.
But if OLT under IGMP Snooping patterns, the travelling across VLAN multicast under PON system can not just be realized, because
The VLAN ID of multicast source can not be converted into for the VLAN ID of up IGMP Report messages.
The content of the invention
For above-mentioned problem, it is an object of the invention to provide the side that travelling across VLAN multicast is realized under a kind of PON system
Method so that OLT can realize travelling across VLAN multicast functionality under IGMP Snoop and IGMP Proxy patterns so that across
VLAN multicasts are realized to be realized under both modes simultaneously.
The purpose of the present invention is achieved through the following technical solutions：
A kind of method that travelling across VLAN multicast is realized under PON system, wherein, comprise the following steps：
After PON system initialization, the configuration of ONU travelling across VLAN multicasts is handed down to by OLT, ONU end receives up
IGMP Report messages；
ONU programs receive the IGMP Report messages of up direction, check whether message has VLAN ID；
If VLAN ID, ONU search travelling across VLAN multicast forward table, otherwise abandoned；
If in travelling across VLAN multicast forward table, ONU finds corresponding VLAN ID, then by up IGMP Report messages
VLAN ID corresponding to being converted to, are otherwise just directly forwarded to PON mouths.
The method that travelling across VLAN multicast is realized under above-mentioned PON system, wherein, in addition to ONU by descending Query messages and under
Row multicast traffic stream is converted to the ONU unique VLAN ID of downlink side.
The method that travelling across VLAN multicast is realized under above-mentioned PON system, wherein, the PON system is wrapped successively by descending direction
Include multicast packet source, OLT, ONU and IPTV service platform.
The method that travelling across VLAN multicast is realized under above-mentioned PON system, wherein, the IPTV service platform includes interacting letter
The IPTV set top box and IPTV TVs of breath.
The method that travelling across VLAN multicast is realized under above-mentioned PON system, wherein, the PON system is APON systems or EPON systems
System or GPON systems.
Compared with the prior art, the beneficial effects of the present invention are：
For PON system, OLT can realize travelling across VLAN multicast under IGMP Snoop and IGMP Proxy patterns
Function so that travelling across VLAN multicast is realized to be realized under both modes simultaneously.
Brief description of the drawings
Fig. 1 shows the structural schematic block diagram of PON system in the prior art；
Fig. 2 shows that OLT opens the schematic flow sheet that IGMP Proxy realize travelling across VLAN multicast in PON system；
Fig. 3 shows the schematic flow sheet for the method that travelling across VLAN multicast is realized under PON system of the present invention.
Embodiment
With reference to schematic diagram and concrete operations embodiment, the invention will be further described.
As shown in figure 3, realizing the method for travelling across VLAN multicast under a kind of PON system of the present invention, comprise the following steps：
After PON system initialization, the configuration of ONU travelling across VLAN multicasts is handed down to by OLT, ONU end receives up
IGMP Report messages；
ONU programs receive the IGMP Report messages of up direction, check whether message has VLAN ID；
If VLAN ID, ONU search travelling across VLAN multicast forward table, otherwise abandoned；
If in travelling across VLAN multicast forward table, ONU finds corresponding VLAN ID, then by up IGMP Report messages
VLAN ID, are then sent to OLT by the IGMP report messages corresponding to being converted to, and are otherwise just directly forwarded to PON mouths.
In embodiments of the present invention, in addition to descending Query messages and downlink multicast stream compression are changed to ONU by ONU
The unique VLAN ID of downlink side.
Referring to shown in Fig. 3, involved PON system is by descending direction in the present invention, successively including multicast packet source,
OLT, ONU and IPTV service platform.IPTV service platform includes interacting the IPTV set top box and IPTV TVs of information, IPTV
Business will carry out parameter setting according to the requirement of different telecommunications companies, and meet the service requirement of PON system.
