Description
Technical field
The present invention relates to network communication and transmission technology, particularly a kind of method realizing tangent rings user data message intercommunication
And equipment.
Background technology
At present, the technology solving double layer network loop problem has RSTP (RSTP, Rapid Spanning
Tree Protocol), each vlan spanning-tree (PVST, Per-VLAN Spanning Tree), Multiple Spanning Tree Protocol (MSTP,
Multiple Spanning Tree Protocol) and rapid ring protection protocol (RRPP, Rapid Ring Protection
Protocol).RSTP/PVST/MSTP application comparative maturity, but convergence time is in second level.RRPP is to be specifically applied to Ethernet
The link layer protocol of ring, has more faster convergence rate than RSTP/PVST/MSTP.And on the convergence time of RRPP and looped network
Nodes are unrelated, can be applicable to the larger network of network diameter.
If Fig. 1 is that RRPP is monocyclic, it comprises main control VLAN (VLAN 3), sub- control VLAN (VLAN 4) and part is protected
Example (protection VLAN 2-10 generally can protect in example controlling VLAN also to add), due to controlling VLAN only to transmit
RRPP protocol massages, so can not carry out data message in all RRPP transmission nodes on this RRPP ring on controlling VLAN
Intercommunication, all can be dropped when receiving the data message with control VLAN tag when the non-RRPP port on RRPP transmission node.
So in Fig. 1, being unable to the data message of intercommunication VLAN 3-4 between user 1 and user 2.Typically in single domain situation
Under, user can evade these and control VLAN, do not forward the data message with controlling VLAN tag as far as possible.
For the data message protecting VLAN in domain, RRPP transmission node can learn all data messages in transmitting procedure
MAC address entries, this means that RRPP transmission node can therefore take substantial amounts of MAC address entries.
When two looped networks are tangent it is necessary to the RRPP ring of two not same areas of configuration is tangent, such as the networking in Fig. 2, two
RRPP tangent rings, it is that (main control VLAN is 3 to 3-4, and sub- control VLAN is 4, gives tacit consent to main control that left side configuration domain 1 controls VLAN
VLAN ID adds 1 and is son control VLAN ID), it is 5-6 that right side configuration domain 2 controls VLAN, the protection example of left side RRPP ring
VLAN is 3-10, and the protection example VLAN of right side RRPP ring is 2-20, and middle transmission node common equipment belongs simultaneously to left side
RRPP ring and right side RRPP ring, therefore middle transmission node common equipment has control VLAN 3-6.
The RRPP ring in left side can forward the VLAN 5-6's (the control VLAN tag of non-left side RRPP ring) of user 1 access
Data message, but the data message of VLAN 5-6 can not forward in right side RRPP ring；The RRPP ring on right side can forward user 2
The data message of the VLAN 3-4 (the control VLAN tag of non-right side RRPP ring) accessing, but the data message of VLAN 3-4 is not
Can forward in left side RRPP ring, the data message of VLAN 3-6 therefore between user 1 and user 2, can not be forwarded all the time.So it is right
Data interchange between tangent rings, user 1 and user 2 also must be evaded falling these and control VLAN 3-6.
Although user can evade control VLAN, this is to waste so that intercommunication between user to a kind of of VLAN resource
VLAN passage reduce.When the tangent rings of more not same areas are configured on transmission node common equipment it is meant that having more
VLAN be unable to intercommunication, the loss of this VLAN resource is just more serious.

To be illustrated with instantiation below.
Embodiment of the method one
, it is 3- that left side configuration domain 1 controls VLAN to the present embodiment taking the networking structure schematic diagram of RRPP tangent rings shown in Fig. 2 as a example
4 (main control VLAN is 3, and sub- control VLAN is 4, and acquiescence main control VLAN ID adds 1, and as son controls VLAN ID), right side configures
It is 5-6 that domain 2 controls VLAN, and the protection example VLAN of left side RRPP ring is 3-10, and the protection example VLAN of right side RRPP ring is 2-
20, middle transmission node common equipment belongs simultaneously to left side RRPP ring and right side RRPP ring, and therefore middle transmission node is public
Equipment has control VLAN 3-6 altogether.
On RRPP ring, the port between equipment is RRPP port, and on RRPP ring, the port between equipment and user is non-RRPP
Port.The present embodiment so that the data message of user 1 one VLAN 4 of transmission is to user 2 is as a example said to technical solution of the present invention
Bright, and premised on the mapping item that there is described data message purpose MAC on transmission node A, Fig. 3 is the flow process of the present embodiment
Figure, comprises the following steps：
Step 301：The master port of host node 1 sends the first hello packet to transmission node on the RRPP ring of left side.
Step 302：Transmission node common equipment receives the first hello packet, fills out in the reserved bit of described hello packet
Fill the first packaging V LAN ID.
In this step, described first hello packet is forwarded to transmission node common equipment, and transmission node common equipment is in institute
The reserved bit stating hello packet fills the first packaging V LAN ID, and described first packaging V LAN ID protects real for left side RRPP ring
Arbitrary VLAN ID of transmission node common equipment all control VLAN is excluded in example.
Wherein, left side RRPP ring protection example VLAN is 3-10, and all control VLAN of transmission node common equipment are 3-
6, thus be excluded that the VLAN ID in the left side RRPP ring protection example of all control VLAN ID of transmission node common equipment is
VLAN 7-10, wherein any one can be it is assumed that select VLAN 7 to make as the first packaging V LAN ID in the present embodiment for selection
For the first packaging V LAN ID.
Equally, if transmission node common equipment receives the first hello packet that host node 2 sends, first
The reserved bit of hello packet fills the second packaging V LAN ID, and described second packaging V LAN ID protects example for right side RRPP ring
Arbitrary VLAN ID of middle exclusion transmission node common equipment all control VLAN, that is, the second packaging V LAN ID can be VLAN2
Or any one of VLAN7-20 (such as VLAN 2).
Step 303：Described first hello packet is transmitted to the secondary port of host node 1 by transmission node common equipment.
Step 304：The secondary port of host node 1 receive that transmission node common equipment sends through the of filling reserved bit
One hello packet, sends the second hello packet to transmission node ring from master port, described second hello packet carries
State the first packaging V LAN 7.
Step 305：All transmission nodes on the RRPP ring of left side receive described second hello packet, start in domain 1
PBB function, and preserve the VLAN 7 in the second hello packet.
In this step, the transmission node B on the RRPP ring of left side, transmission node common equipment, transmission node A are successively received institute
State the second hello packet, be respectively started the PBB function in respective domain 1, and preserve the VLAN 7 in the second hello packet.
Preserving VLAN 7 is in order to when the non-RRPP port of the transmission node on the RRPP ring of left side receives with control VLAN
During 3 or VLAN 4 data message, carried out PBB encapsulation, the B-VLAN of encapsulation is VLAN 7, so it is ensured that carrying
The data message controlling VLAN 3 or VLAN 4 normally forwards between transmission node on RRPP ring.
Step 306：User 1 sends the data message of VLAN 4 to user 2, and the source MAC of described data message is user's 1
MAC, purpose MAC is the MAC of user 2.
Step 307：Transmission node A receives the data message that user 1 sends, and carries out PBB envelope to described data message
Dress.
In this step, transmission node A receives the data message that user 1 sends, and the VLAN ID due to data message is
The control VLAN of left side RRPP ring, therefore will carry out PBB encapsulation to this data message, to ensure that this data message is successfully forwarded to
User 2.Before PBB encapsulation, the transmission node A first mapping item according to the local preservation of described data message purpose MAC inquiry, from
And search the transmission node bridge MAC being connected with the user receiving described data message, it is in the present embodiment and search and user 2 phase
The bridge MAC of transmission node C even, as purpose MAC in BMAC, then carries out PBB encapsulation.PBB encapsulation operation is：Envelope
Purpose MAC in dress B-MAC is the bridge MAC in the correspondence mappings list item inquiring, and source MAC is the bridge MAC, B- of transmission node A
VLAN is VLAN 7, and I-SID is preset value, is set to full F in the present embodiment, for representing that this PBB message is in RRPP domain
PBB message.Wherein the value of this I-SID specifically can be worth with system default or human configuration one.
If transmission node A does not inquire and data message purpose MAC (MAC Address of user 2) corresponding mapping table
, then need to make this data message reach user 2 using broadcast mode, will purpose MAC in B-MAC be encapsulated as broadcasting MAC.
Typically, when transmitting message for the first time between user 1 and user 2, broadcast mode can be passed through, but after transmitting message, transmission
Node A, and transmission node C all can learn to corresponding mapping item (i.e. data message source MAC and PBB encapsulation BMAC
In source MAC), so, subsequently just can directly inquire about mapping item to carry out PBB encapsulation, wherein concrete of mapping item
Habit process will not be described here.
Step 308：Data message forwarding after PBB is encapsulated by transmission node A is gone out.
Because the data message after PBB encapsulation is unicast message, therefore transmission node A is transmitted to this ring by RRPP port
Next-hop transmission node, is transmission node common equipment in the present embodiment.
Step 309：Transmission node common equipment receives the data message after PBB encapsulation, if described data message
User vlan ID belongs to the protection example VLAN ID of described second RRPP ring, then the BVLAN in this PBB encapsulation of data message
Heavy label is described second packaging V LAN, then forwards from the RRPP port of described second RRPP ring；Otherwise decapsulate institute
State PBB encapsulation of data message, then forward from the RRPP port of described second RRPP ring.
In this step, transmission node common equipment receives the datagram through PBB encapsulation that transmission node A sends
Literary composition, first determines whether whether the user vlan ID of described data message belongs to the protection example VLAN ID of described second RRPP ring.
In the present embodiment, the user vlan ID of described data message is VLAN 4, and the protection example of the second RRPP ring is VLAN2-20,
The described user vlan ID stating data message belongs to the protection example VLAN ID of the second RRPP ring, and therefore transmission node is public sets
Standby is described second packaging V LAN the BVLAN heavy label in this PBB encapsulation of data message, then from described second RRPP ring
RRPP port forwards.Here the second packaging V LAN is the 2nd RRPP of exclusion transmission node common equipment all control VLAN
Arbitrary VLAN ID of ring protection example it is assumed that being VLAN 10, then by the BVLAN (VLAN 7) in this PBB encapsulation of data message
Heavy label is VLAN 10, then forwards from the RRPP port of described second RRPP ring.
If the protection example of the second RRPP ring is VLAN 5-20, the user vlan 4 of this PBB encapsulation of data message is not
Belong to the protection example VLAN ID of the second RRPP ring, now message is directly decapsulated, by second by transmission node common equipment
The RRPP port of RRPP ring forwards the data message after decapsulation.
Step 310：Transmission node C receives the data message after the PBB encapsulation that transmission node common equipment sends, deblocking
Fill this message and be transmitted to user 2.
In this step, transmission node C receives the data message after the PBB encapsulation that transmission node common equipment sends, will
It is decapsulated, and the data message after decapsulation is sent to user 2 by non-RRPP port.
In the present embodiment, if transmission node A carries out PBB encapsulation, do not inquire mapping item, but by destination address
