The problems for generating some management, the development of network technology must adapt to new virtualization technology trend.Therefore, IEEE
(Institute of Electrical and Electronics Engineers, Institute of Electrical and Electric Engineers) tissue
A series of 802.1 new standards are proposed for new technologies such as data center's virtual machine (vm) migrations, including 802.1Qau (lead to by congestion
Accuse), 802.1Qaz (enhanced transmission selection), 802.1Qbb (the stream control based on priority), 802.1Qbg (edge virtual bridge),
802.1BR (virtual bridge Interface Expanding) etc..
Wherein, remote exchange can be deployed as the policy control interchanger in virtual environment by 802.1BR standards, pass through
Multiple tunnels, edge virtual bridge copy packet is allowed to one group of remote interface, utilize the serial interface of waterfall type and flexible
Planned network is more effectively multicast frames, broadcast frame and unicast frame distribute bandwidth.

Embodiment
In order to provide effective implementation, the invention provides following embodiments, below in conjunction with Figure of description to this
Inventive embodiments illustrate.
Present invention firstly provides a kind of data forwarding port selecting method of vertical stack system, as shown in Fig. 2 including such as
Lower step：
Step 201：Multicast/broadcast member is scanned, identifies aggregation port therein；
Step 202：From the member port of the aggregation port, multicast/broadcast exit port is selected according to setting means；
Step 203：The multicast/broadcast exit port is bound with sendaisle so that message can be sent out when forwarding
It is sent to the multicast/broadcast exit port.
From the above it can be seen that the data forwarding port selecting method of vertical stack system provided by the invention, energy
It is enough to select a port to be received and dispatched as the message of all member ports of aggregation port or other data messages from aggregation port
Exit port, solve in the case of by LACP configuration distributings to CB, multicast or broadcast member in exist by one or two
The port trunking of above PE equipment into aggregation port and the problem of lead to not routing.
In the specific embodiment of the invention, the moment is forwarded when different messages forward or in different messages, can basis
The actual conditions of port occupancy and the content of message, attribute etc. select different ports to be used as end in an aggregation port
Mouthful.
In the specific embodiment of the invention, the setting means can be random selection mode.
In some embodiments of the invention, the aggregation port is the port based on link aggregate control protocol LACP, its
Member port includes the port of ports-Extending PE equipment, and the ports-Extending PE equipment comprises at least one.
In some embodiments of the invention, the step that the multicast/broadcast exit port and sendaisle are bound
Suddenly specifically include：
Extract the mark of the multicast/broadcast exit port；
Multicast is sent to the multicast/broadcast extension gap marker ECID and the mark of the multicast exit port of equipment generation
It is filled in together in sendaisle logon message and is sent to ports-Extending PE equipment；
According to the multicast/broadcast extension gap marker ECID parsed in the sendaisle logon message, by described in
Multicast/broadcast exit port and the Multicast Extensions gap marker ECID corresponding relations of generation are simultaneously tied up with the sendaisle
It is fixed.
When the ECP Extended Capabilities Port on PE is an aggregation port by LACP protocol aggregations, CB can record this aggregation port
Member corresponding to port-mark.And aggregation port member port possesses different ECID respectively, LACP ports extend as PE
The logic interface that mouth is aggregating, will not reallocate new ECID.Now, if by the aggregation port add some multicast or
Broadcast group, CB send PE CSP message E-channel registration messages to PE, and PE, which is received, carries E-channel registration messages
After CSP messages, multicast ECID and the aggregation port can be bound.
In some embodiments of the invention, the scanning multicast/broadcast member, identify the step of aggregation port therein it
Before, referring still to Fig. 2, in addition to：
Step 200：The physical port of the ports-Extending PE equipment is set as that multicast/broadcast sends the extension end of equipment
Mouthful, it is control bridge CB equipment that the multicast/broadcast, which sends equipment,；
Step 2001：After the ECP Extended Capabilities Port is polymerized at least one aggregation port, by least one polymerization end
Mouth is added in multicast/broadcast group, turns into the multicast/broadcast member in multicast group.
In 802.1BR agreements, PE can notice PE equipment successively to CB by Extended Port Create messages
Port.CB receives the message, therefrom parses the mark of PE ports, and records.At the same time, CB can be uniquely every
One PE port assignment, one ECID, and the corresponding relation of ECID and reception the message port is issued in CB hardware, this
Sample just creates an expansion interface on CB.By Extended Port Create messages it is continuous on send with ECID
Hair, CB can create ECP Extended Capabilities Port one by one on CASCADE mouths and be corresponded with each actual port on PE.Meanwhile
CB can send Extended Port Create Reply messages to PE, and carry and be assigned on PE ports in the message
ECID, the unique mark as the port on PE.
Specifically, as shown in figure 1, control bridge device CB and bridge Interface Extender BPE1 is extended when creating ECP Extended Capabilities Port
Process is：
101：Control bridge device CB to find BPE1, initiate internal extended bridge Interface Extender and create process.Control bridge device
Mutually hair LLDP (Link Layer Discovery Protocol, link layer hair between CB and extension bridge Interface Extender BPE1
Existing agreement) protocol massages, find the direct-connected port of other side and other side.
102：PE CSP are initialized.After CB and BPE1 have found other side mutually, independently trigger equipment and send CSP
Open (CSP openings) message, notify CSP agreements to open to other side, while wait other side to respond.
103：After CB equipment or PE equipment receive CSP Open messages, CSP Open Reply messages are sent to opposite end
Carry out response.Only when CB and PE receive CSP Open Reply messages, it was demonstrated that bilateral agreement, equipment are all ready, Neng Goulian
Connect foundation.
104：When bilateral agreement, equipment are all ready, CB cans initialize flow port on BPE1.By sending Port
Parameters Set (port parameter setting) message carries out some settings to PE ports.PE replys Port Parameters
Set Reply messages are responded.
105：CB initialization C-VLAN components port, PE create ECP Extended Capabilities Port.PE sends Extended Port to CB
Create (ECP Extended Capabilities Port establishment) message, physical port information on PE is carried in the message.PE to CB by sending Extended
The port of Port Create message notification devices, CB receive Extended Port Create messages, by parsing, obtain
The PE port-marks that are carried in message are simultaneously recorded.Specifically, for example, sharing N number of port on PE, PE is each port assignment
A port identifies, such as the numeral such as 1,2,3 ... N is used as uniquely tagged.In fact, the port-mark includes but is not limited to count
Word, if can distinguish different port can, for example, it is also possible to be symbol etc..These port-marks and port are recorded on PE
Corresponding relation.Finally, the upper all of the ports of PE all report CB by way of sending Extended Port Create messages.
106：After CB receives these Extended Port Create messages, parse port-mark therein such as 1,
2nd, 3 ... N etc., and the size for each such PE port assignments one unicast ECID, the ECID is 0-4 kilobytes, together
When, ECID and PE the port-mark corresponding relation for port assignment are recorded in CB local database or resource chained list,
And transmittable Extended Port Create Replay messages are replied.
107：It is similar with prior process that subsequent expansion port creates process.
The port that CSP messages are received on CB is referred to as CASCADE ports, such as Port1, Port2 in Fig. 3.CB will connect
Receive the CASCADE ports for the Extended Port Create messages for carrying port-mark n and the ECID mono- for port n distribution
The part that hardens is removed, is that the port on PE creates respective extension port.Meanwhile CB will seal to be identified as the ECID of n port assignment
In Extended Port Create Reply messages, PE is sent to.By taking Fig. 3 as an example：PE1 and PE2 have port respectively
Port3、Port4；Port, Port5, Port6 port.PE1 and PE2 is respectively that the port-mark that these ports are extracted or constructed is
Numeral 3,4；5、6、7.PE1 records port and port-mark corresponding relation：Port3-3, Port4-4.PE2 records port and port
Identify corresponding relation：Port5-5, Port6-6, Port7-7.PE sends Extended Port Create messages, message to CB
The port-mark of middle carrying 3,4,5,6,7.Respectively, it is 3,4 that the message that PE1 is sent, which carries port-mark,；The message that PE2 is sent
The port-mark of carrying is 5,6,7.Port1 receives the Extended Port Create messages of PE1 transmissions, and Port2 is received
The Extended Port Create messages sent to PE2.CB is port Port3, Port4 points that PE1 upper ports are identified as 3,4
With ECID：13、14；Port Port5, Port6, Port7 to be identified as 5,6,7 on PE2 distribute ECID：15、16、17.Note
Record corresponding relation PE1:3-13、4-14；PE2:5-15、6-16、7-17.Wherein PE1, PE2 be PE on port-mark, the latter
For the ECID of port-mark distribution.CB by this to should corresponding relation insert Extended Port Reply messages, to PE send out
Send.PE receives Extended Port Create Reply messages, parses the ECID wherein distributed and port-mark (PE1：
3-13、4-14；PE2：5-15,6-16,7-17) after, then the content (PE1 with locally having recorded：Port3-3、Port4-4；PE2：
Port5-5, Port6-6, Port7-7) compare.ECID and its port are obtained, hardware is then issued, by ECID and corresponding physics
Mouth is bound.Each port is just so on PE and CB extension mouth generates one-to-one relation, reference picture 3,
Port3, Port4, Port5, Port6, Port7 correspond to ECP Extended Capabilities Port Bep3, Bep4, Bep5, Bep6, Bep7 respectively.
As shown in figure 3, working as CB and PE has formed 802.1BR environment, now, if two ECP Extended Capabilities Ports are polymerized to one
Aggregation port, turn into an aggregation port as Bep4, Bep5 are polymerized to an aggregation port TRUNK1 or Bep6, Bep7 polymerization
There is new logic port to produce on TRUNK2, PE.Wherein, E1 E-channel1, E2 E-channel2.Now, it is polymerization
Port sets mark, has two schemes available：1) aggregation port (such as TRUNK1/TRUNK2) regenerates port-mark X
And send Extended Port Create messages to CB, CB be the logic port generate new unicast ECID-X and
Send back and in Extended Port Create Reply messages.But there is following problem in this method：First, account for
With unicast ECID resources, reduce the expansible capacity in port；Secondly, even if the problem of not considering ECID, the unicast redistributed
ECID-X can not with actual physics port binding, because actual physical port has possessed allocated unicast ECID, such as 13,
14、15、16、17；Again, 802.1BR agreements are not specified by logic port distribution unicast ECID to be.3 points based on more than,
TRUNK1, TRUNK2 no longer send Extended Port Create messages to CB to be applied.Therefore, TRUNK1, TRUNK2
Exist as the logic interface floated on BEP mouths, bound therewith without single unicast ECID.Although TRUNK1, TRUNK2 do not have
New unicast ECID is corresponded to therewith, but CB can record aggregation port member, CASCADE ports and its unicast ECID-
TURNK1:4-14-Port1(CASCADE)、5-15-Port2(CASCADE)；TRUNK2：6-16-Port2(CASCADE)、7-
17-Port2 (CASCADE), the visible Fig. 4 A of detailed device, Fig. 4 B.
TRUNK1, TRUNK2 are added in some multicast or broadcast group, CB can be that multicast/broadcast distributes a multicast
ECID, and multicast ECID is tied on all members of this multicast group/broadcast group.CB sends to PE and carries E-
Channel Register (E-channel registrations) message.PE equipment receives E-channel Register messages and parsed
Multicast ECID therein.And the ECID and physical port actual on PE are bound.
Due to Bep4, Bep5 and Bep6, Bep7 the LACP ports aggregated into do not have corresponding unicast ECID can and group
Broadcast E-channel to be bound, therefore in embodiments of the present invention, send PE CSP messages in CB and carry out E-channel and end
Before mouth binding, multicast member is scanned by CB, if some member is LACP aggregation ports and its member port is extension mouth,
So CB just calculates exit port of the member port for electing LACP as aggregation port, the exit port according to setting means
For receiving multicast or the message of broadcast or other data；After selecting exit port, extraction member's port-mark, and the multicast
ECID is filled in E-channel Register messages and is sent to PE, is bound.
In some embodiments of the invention, the setting means includes hash algorithm.
In a kind of specific embodiment of the present invention, by taking Fig. 3 as an example, TRUNK1 and Bep6 that Bep4, Bep5 are polymerized,
The TRUNK2 that Bep7 is polymerized is added separately in multicast ip224.1.1.1 and VLAN1000.CB records TRUNK1, TRUNK2
And its member identities and ECID：3-13、4-14；5-15、6-16.CB is that TRUNK1, TRUNK2 distribute multicast ECID (scope 4k
+ 1~16k) it is 5001,12002.Hash multicast ECID1 (5001) divided by TRUNK1 member can will be added with TRUNK1
The remainder (such as remainder is m) of number selectes the m+1 port of LACP member as multicast exit port as final value:
Multicast ECID1%2=5001%2=1, remainder 1, then take TRUNK1 second port Bep5 finally selected as algorithm
Exit port represents LACP ports and is added in multicast ip224.1.1.1.And by under the CASCADE mouths (Port2) where Bep5 mouths
CB hardware is sent out, is added in multicast ip224.1.1.1.Meanwhile 5-15 (unicast ECID) and 5001 (groups will be identified corresponding to Bep5
Broadcast ECID) insert E-channel Register messages transmission PE.If TRUNK1 is added to another multicast
Ip224.1.1.2, and the multicast ECID that CB is the Multicast Group Assignment is 5002, then according to same algorithm：5002%2=0,
The port so elected is TRUNK1 a port Bep4.Insert the port of E-channel Register messages
Mark, unicast ECID, multicast ECID are respectively just 4,14,5002, and the CASCADE mouths for issuing CB hardware are Port1.With
TRUNK2 is added exemplified by VLAN1000, it is assumed that CB is that the multicast ECID of VLAN1000 distribution is 12002, then according to algorithm picks
The port gone out is：12002%2=0, corresponding ports are TRUNK2 a port Port6, and unicast ECID is 16, end
Mouth is identified as 6.The CASCADE mouths for issuing CB hardware are Port2, insert the mark of the port in E-channel Register messages
Knowledge, unicast ECID, multicast ECID are respectively：6、16、12002.
PE receives E-channel Register messages, parses multicast ECID and port-mark therein, only with
TRUNK1 is added exemplified by multicast ip224.1.1.1.PE parses 5,15,5001 from E-channel Register messages.Root
According to the record shown in Fig. 4 A, Fig. 4 B, it is Port5 to find corresponding ports, is then bound Port5 and multicast ECID5001.
So, that be actually added into multicast ip224.1.1.1 is exactly port Port5, and Port4 is not in multicast ip224.1.1.1.
Similarly, TRUNK1 is added to multicast ip224.1.1.2 and TRUNK2 and is added to VLAN1000 and can adopt this method, final real
The port that border adds is respectively Port4 and Port6.
So the retransmission method proposed according to above example of the present invention, when a multicast message, in multicast group, (ip is
224.1.1.1 when) forwarding, if its multicast exit port is TRUNK1, then it can find exit port Port1 on CB
(the upper Port1 of CB and the IP 224.1.1.1 of multicast group play hardware), after message reaches PE, it is forwarded to Bep5.
Because the aggregation port does not have the ECID (different from LACP member port ECID) for distributing unicast, i.e., CB fails
The LACP aggregation ports perceived on PE are an independent extension mouth.So some of LACP can be chosen by a kind of method
Member port (PE ECP Extended Capabilities Port), is bound with multicast ECID.When flux of multicast forwards or copies to the LACP,
This member port elected is copied to regard to forwarding.LACP port assignment ECID are given so as to avoid, had both saved unicast ECID
Resource, reduce the complexity for carrying out hardware hash routings on PE between different ECP Extended Capabilities Ports again.
