Step 301：Receive the multicast message that the 3rd ECP Extended Capabilities Port is submitted；For example, in Fig. 1, when ECP Extended Capabilities Port f is connected
Terminal to its belonging to the first multicast group in when sending a multicast message, the 3rd outside bridge port expander 23 can will be connect
The multicast message received submits to control bridge 1, and control bridge 1 can receive multicast message from virtual port f, that is, receive extension end
The multicast message that mouth f is submitted.
Step 302：Multicast message is sent to the outside bridge port expander being directly connected to control bridge.
Here, control bridge 1 is when receiving a multicast message, it is thus only necessary to is sent to multicast message and the control bridge
The 1 outside bridge port expander being directly connected to, generally outside bridge port expander all includes or level is associated with some ECP Extended Capabilities Ports, such as
Shown in Fig. 1, control bridge 1 needs only to the multicast message that ECP Extended Capabilities Port f is submitted being sent to the first outside bridge port expander
21 and the 3rd bridge port expander 23, i.e., only it need to send two parts, rather than three parts；, can be very big accordingly, with respect to prior art
Reduction control bridge 1 and outside bridge port expander between the data volume to be transmitted, reduce both between link burden.
Preferably, the method for the retransmitting multi-casting message, it is further comprising the steps of：It is determined that any void in this control bridge
Intend port and belong to same multicast domain with the 3rd ECP Extended Capabilities Port, then pass through the virtual port retransmitting multi-casting message.
In practice, the virtual port in control bridge is also possible to that a terminal can be directly connected to, if the virtual terminal
Mouth belongs to same multicast domain with the 3rd ECP Extended Capabilities Port, then the multicast message should be also sent to the virtual port.
Preferably, it is described that multicast message is sent to the outside bridge port expander being directly connected to control bridge, including：Obtain
Take the 3rd set that all ECP Extended Capabilities Ports being in extension bridge with the 3rd ECP Extended Capabilities Port in same multicast domain are formed；
It is provided with any outside bridge port expander for confirming to be directly connected to the control bridge or level is associated with the 3rd set
In any ECP Extended Capabilities Port when, by the E-CID of the 3rd ECP Extended Capabilities Port（E-Channel Identifier）In embedded multicast message, and
Multicast message is sent to the outside bridge port expander.
Here, if an outside bridge port expander is not provided with and does not also have level to be associated with and the 3rd extension end
It is when mouth is in the ECP Extended Capabilities Port of same multicast domain, then obvious just It is not necessary to give the more reports of outside bridge port expander transmission
Text, so as to which can saves the bandwidth between control bridge and outside bridge port expander.Here, it is necessary to inform that outside bridge port expands
It is as transmitted by the 3rd ECP Extended Capabilities Port, for example, can be embedding by the E-CID of the 3rd ECP Extended Capabilities Port that exhibition device, which can obtain multicast message,
Enter multicast message.
The embodiments of the invention provide a kind of device of the retransmitting multi-casting message for control bridge, including with lower module：The
One message receiving module, the multicast message submitted for receiving the 3rd ECP Extended Capabilities Port；First message sending module, for inciting somebody to action
Multicast message is sent to the outside bridge port expander being directly connected to control bridge.
The embodiment of the present invention three provides a kind of outside bridge port expander of being used for based on embodiment two and issues multicast
The method of message, as shown in figure 4, comprising the following steps：
Step 401：Receive multicast message；
Step 402：It is determined that any ECP Extended Capabilities Port in this outside port expander（Extended Port）With the 3rd extension end
When mouth is in same multicast domain, multicast message is issued by the ECP Extended Capabilities Port；Here, because outside port expander has carried
The configuration information of the preceding multicast domain that have received from control bridge 1 in the extension bridge, and include E-CID in multicast message, because
This, it can be determined which ECP Extended Capabilities Port gone out thereon belongs to same multicast domain with the ECP Extended Capabilities Port corresponding to the E-CID.Such as：
（1）Outside port expander knows all expansions that same multicast domain is not at the 3rd ECP Extended Capabilities Port in extension bridge in advance
Port is opened up, can necessarily be informed in all expansions for being not at same multicast domain in this outside port expander with the 3rd ECP Extended Capabilities Port
Port is opened up, when issuing, avoids these ECP Extended Capabilities Ports；（2）Outside port expander knows extension bridge in advance
In all ECP Extended Capabilities Ports that same multicast domain is in the 3rd ECP Extended Capabilities Port, can necessarily be informed in this outside port expander
In all ECP Extended Capabilities Ports of same multicast domain are in the 3rd ECP Extended Capabilities Port, then only issue multicast message by these ECP Extended Capabilities Ports
.
Step 403：Pass through the cascade port in the bridge port expander of this outside（Cascade Port）Issue multicast message.
Here it is possible to understand, if there is no ECP Extended Capabilities Port in the bridge port expander of this outside, not operating procedure
402, if not cascading port, not operating procedure 403.
In the Br agreements of IEEE 802.1, some outside bridge port expanders in an extension bridge are a layering knots
Structure, in outside bridge port expander, terminal can be directly connected to by ECP Extended Capabilities Port, is cascaded by cascading port outside next layer
Portion's bridge port expander and bridge port expander outside last layer is connected to by uplink port.It is understood that outside bridge
Port expander issue a process of multicast message it is to be understood that by uplink port receive last layer issued it is more
Text is reported, if being provided with the ECP Extended Capabilities Port that same multicast domain is in the 3rd ECP Extended Capabilities Port in the outside bridge port expander,
Multicast message is then transmitted to by terminal by the ECP Extended Capabilities Port；If cascaded in the outside bridge port expander by cascading port
Have next layer of outside bridge port expander, then next layer of outside bridge port expander be possible to be provided with the 3rd ECP Extended Capabilities Port
, then also should be by cascading port by multicast message to being issued to next layer of outside bridge port in the ECP Extended Capabilities Port of same multicast domain
Expander.
For example, as shown in figure 1, port a, b, e and f belong to the first multicast group, when the multicast message transmitted by the f of port is controlled
Bridge 1 processed is forwarded to after the first outside bridge port expander 21, and because ECP Extended Capabilities Port c is not belonging to the first multicast group, then shielding is expanded
Open up port c；Next layer of the second outside bridge port expander 22 is handed down to by cascading port 211 by multicast message afterwards, by
The first multicast group is belonged in ECP Extended Capabilities Port a and b, then multicast message is issued by ECP Extended Capabilities Port a and b, then terminal can just connect
Receive multicast message.Accordingly, in the second outside bridge port expander 22, because ECP Extended Capabilities Port d is not belonging to the first multicast group,
Then shield ECP Extended Capabilities Port d；And ECP Extended Capabilities Port e belongs to the first multicast group, then the multicast message is sent by ECP Extended Capabilities Port e, that is, reached
To terminal；Preferably, due to ECP Extended Capabilities Port f and identical with the ECP Extended Capabilities Port that this sends the multicast message（An if for example, expansion
The E-CID for opening up original ECP Extended Capabilities Ports of the PCID of port with sending multicast message is identical, then it represents that and the two ECP Extended Capabilities Ports are identical,
Here E-CID is that E-Channel Identifier, PCID are Port E-CID）, then can shield.
Preferably, the cascade port in the bridge port expander by this outside issues multicast message, including：Pass through this
All cascade ports in outside bridge port expander issue multicast message.Here, because cascade port be possible to level be associated with
3rd ECP Extended Capabilities Port is in the ECP Extended Capabilities Port of same multicast domain, therefore, can issue multicast message by all cascade ports, so as to
Ensure that multicast message can reach purpose terminal.
Preferably, the cascade port in the bridge port expander by this outside issues multicast message, including：It is determined that
Any cascade port level in the bridge port expander of this outside is associated with the extension end that same multicast domain is in the 3rd ECP Extended Capabilities Port
During mouth, multicast message is issued by the cascade port.If it is understood that one in the bridge port expander of this outside
Cascade port does not have level to be associated with the ECP Extended Capabilities Port for being in same multicast domain with the 3rd ECP Extended Capabilities Port, then obviously It is not necessary to by being somebody's turn to do
Cascade port issues multicast message.
The embodiment of the present invention additionally provides a kind of device for issuing multicast message for outside bridge port expander, including
With lower module：Second message receiving module, for receiving multicast message；
Second message sending module, for it is determined that any ECP Extended Capabilities Port and the 3rd ECP Extended Capabilities Port in this outside port expander
During in same multicast domain, multicast message is issued by the ECP Extended Capabilities Port；
