The encapsulation mode that the miniaturization access PTN device manages message according to described second adjusts the Working mould of itself
Formula.
In the embodiment of the present application, miniaturization access PTN device, can also be according to the after identifying the second management message
The encapsulation mode of two management messages carrys out the operating mode of adjust automatically itself, achievees the purpose that automatically configure operating mode.That is,
After the encapsulation mode for receiving the second management message, to reach both sides' peer-to-peer communications, it is necessary to the operating mode for adjusting itself, with
So that the encapsulation mode of the message itself sent out is identical as the encapsulation mode for the message that other side sends out.

In implementation, the second management message described in the transmission device transparent transmission in the Metropolitan Area Network (MAN) is specifically as follows, and receives institute
After stating the second management message that auxiliary configuration equipment is sent, the second management message is encapsulated as third and manages message, it is described
It is to increase multiprotocol label switching (MPLS, Multi- on the basis of the second management message that third, which manages message,
Protocol Label Switch) label switched path (LSP, Label Switching Path) and PW labels message；?
Third management message is descapsulated into the second management message when being sent to miniaturization access PTN device.
In general, the transmission of message be from an interface (being assumed to be interface A) of Metropolitan Area Network (MAN) be transferred to Metropolitan Area Network (MAN) another
Interface (is assumed to be interface B), and in order to ensure that message is accurately transferred to correct interface in Metropolitan Area Network (MAN), metropolitan area network equipment can be
A mouthfuls are packaged message, and write-in destination is two labels of interface B, i.e. LSP and PW to indicate.When message reaches interface B
When, metropolitan area network equipment removes the LSP encapsulated outside message and PW, in this way, from B mouthfuls of messages out and the A mouthfuls of messages entered
It is identical, such process is transparent transmission.
In the prior art during transparent transmission using plus VLAN and realize that transparent transmission, VLAN ID only have by the way of removing VLAN
12bit, and realized by the way of increasing MPLS LSP and PW label, removing MPLS LSP and PW labels in the embodiment of the present application

More service groups.
In implementation, the auxiliary configuration equipment manages message by described first with preset encapsulation mode and is packaged into the second pipe
Message is managed, is specifically as follows：After auxiliary configuration equipment manages message increase VLAN marks by described first, to manage communication port
(MCC, Management Communication Channel) standard packaging format is packaged into the second management message.
The case where being same plant equipment for access PTN device and convergence PTN device, management passage can be able to be mark
The accurate channels MCC, it can be to manage message first that miniaturization, which accesses management message on the interface that PTN device is docked with Metropolitan Area Network (MAN),
On the basis of increase VLAN marks, again outer envelope label 13, ACH, MEL VER (Maintenance Entity
Group Level version) etc. labels (MCC standard packagings) message, wherein VLAN mark can be used for distinguish protocol stack
Logic interfacing.
The access side device of same producer is directly docked with convergence side apparatus, and the forwarding of Metropolitan Area Network (MAN) is not present, therefore, same
It is executed by Routing Protocol in management passage between plant equipment, the forwarding of the management message in transmission process is forwarded according to IP
, that is, auxiliary configuration equipment to the forwarding for managing message is forwarded on different vlan sub-interfaces by the Routing Protocol of equipment room,
Then the standard packaging format and VLAN of MCC are encapsulated again according to vlan sub-interface.
In implementation, the auxiliary configuration equipment manages message by described first with preset encapsulation mode and is packaged into the second pipe
Message is managed, is specifically as follows：Auxiliary configuration equipment manages described first after message increases VLAN marks and is further added by MPLS outer layers
VLAN (that is, MVLAN) is identified and MCC encapsulation, forms the second management message；Transmission device in Metropolitan Area Network (MAN) is by described second
Message transmission is managed to miniaturization access PTN device, is specifically as follows：Transmission device in Metropolitan Area Network (MAN) is identified according to MVLAN will
The second management message transmission to miniaturization accesses PTN device.
The case where across metropolitan area network construction for miniaturization access PTN device, management passage retains and adds outside MCC encapsulation format
One layer of VLAN, UNI docking modes may be used in business, overlay modes may be used in management passage.Under this scene, auxiliary
Routing forwarding can be carried out by ospf protocol by configuring between equipment and miniaturization access PTN, outer layer adds the encapsulation of MCC.
Transmitting message is distinguished according to VLAN in Metropolitan Area Network (MAN), and MVLAN belongs to VLAN, and the transmission device in Metropolitan Area Network (MAN) is exactly
Carry out transmitting message according to this VLAN ID.
In implementation, the auxiliary configuration equipment manages message by described first with preset encapsulation mode and is packaged into the second pipe
Message is managed, is specifically as follows：The auxiliary configuration equipment is according to pair between pre-stored purpose IP address and VLAN marks
Relation table is answered, determines the corresponding VLAN marks of the first management message, and manage message by described first and increase the VLAN
Mark forms the second management message.
The case where across metropolitan area network construction for miniaturization access PTN device, when management passage is UNI patterns, auxiliary configuration
Can not be by routing forwarding between equipment and miniaturization access PTN device, but the correspondence of IP address and VLAN can be passed through
Relation list is forwarded.For example IP is that the miniaturization of 192.168.1.2 accesses the management passage (Metropolitan Area Network (MAN) where PTN device
The tunnels PW) the MVLAN of logic interfacing be 23, the corresponding of a 192.168.1.2 and VLAN 23 is done inside X equipment and is closed
It is table, then plus VLAN 23 when receiving the message forwarding item of this purpose IP address.
Auxiliary configuration equipment to the forwarding for managing message is forwarded according to the correspondence of the IP and VLAN of configuration, metropolitan area
Metropolitan Area Network (MAN) transmission device in net is to carry out transfer management message to miniaturization access PTN according to VLAN.
In implementation, the method may further include：
The auxiliary configuration equipment by the second management message before being sent to Metropolitan Area Network (MAN), for the second management report
Text addition overhead messages, and the overhead messages are managed into message with described second and are sent to Metropolitan Area Network (MAN) together；Wherein, described auxiliary
Help the identification field that message includes different from service message.
In order to further distinguish message and general service message, the embodiment of the present application can also be matched by auxiliary to be installed
Standby to send overhead messages, since general business message only has one layer of message, the message that identifies for needs is by auxiliary with installing
It is necessary to manage two kinds of message and Added Management message after standby increase overhead messages, so as to distinguish other messages.Its
It is secondary, can also include the identification field (such as 0x6666) different from service message in overhead messages, come whereby the message with
Other messages distinguish.Identification field is the TYPE type fields of ether network packet, for example, since service message will not be used
0x6666 values, therefore 0x6666 may be used to identify.
For the ease of the implementation of the application, it is described in detail below with a specific example.
Inventor first analyzes the message format of each node of existing network, and Fig. 4 shows the application reality
The analysis schematic diagram to existing network in example is applied, as shown, this five nodes of A, B, C, D, E are described below respectively：
A：The interface of management server and Metropolitan Area Network (MAN), this interface of Metropolitan Area Network (MAN) and the network interface of PC are the interfaces of equity,
The message format of transmission is two layers of ether network packet, specific as follows shown：
| DMAC | SMAC | TYPE | PAYLOAD | CRC |
B：Node message format in Metropolitan Area Network (MAN) in transmission process is to increase MPLS LSP on the basis of A nodes
With PW etc., tubing envelopes message format is as follows：
C：There are three types of access ways, respectively customer network interface for the docking of the access node of Metropolitan Area Network (MAN) and miniaturization PTN
(UNI, User Network Interface) docking, Network-Network interface (NNI, Network-Network Interface)
Docking, OVERLAY docking, are described as follows：
More common, the C under UNI docking modes that can be seen that the first UNI docking mode from three kinds of access ways above
The message format of node is as follows：
| DMAC | SMAC | VLAN | TYPE | PAYLOAD | CRC |
As can be seen that the message of C nodes and the difference of A nodes are above, a vlan domain is increased, for distinguishing industry
Business and management logic interfacing.
D：For the node before miniaturization access PTN device internal control CPU, this node is to introduce automatic study
The dummy node for managing VLAN and accessing, message format are identical as C nodes.
E：For CPU management IP protocol stack entrance in miniaturization access PTN device, learn pipe automatically also for introducing
The dummy node managed VLAN and be arranged.
By analysis above, it can be found that having no idea to realize the automatic study for managing VLAN under existing structure.Cause
This, the embodiment of the present application is modified existing network topology.
Fig. 5 shows modified network topology schematic diagram in the embodiment of the present application, as shown, being repaiied to existing network
It is to increase an equipment between management server in machine room and Metropolitan Area Network (MAN) to change, to realize the function of automatic study and configuration of IP.
Wherein, the message of A nodes with modification before it is identical, the message of B node be increased on the basis of A ' and C LSP with
PW, to realize that the transparent transmission of A nodes and C nodes (and is needed from A nodes to C nodes in existing scheme plus VLAN operations, saved from C
Point needs VLAN to operate to A nodes).Message reason of changes between A ' and C is, from A ' to E, the equipment on side is all point
It is miniaturization access PTN, for the message both sides on network management path, as long as accomplishing that the encapsulation of equity and decapsulation can be real
Existing intercommunication, can also increasing some instruction signalings, (existing scheme cannot achieve the reason learnt automatically for learning automatically
It is the signaling that can not increase study).
According to realization method, the application scenarios of miniaturization access PTN device can be divided into the following two kinds：
The first scene, miniaturization access PTN device and the equipment that convergence PTN device is same producer, between the two
Management passage can be the channels MCC of standard, the management message lattice on interface that miniaturization access PTN device is docked with Metropolitan Area Network (MAN)
Formula can be：
Wherein, M_DMAC is the MAC Address outside MPLS, and label13, ACH, MEL VER are MCC standard packagings, from DMAC
It is CPU management message to be processed backward, Software Protocol Stack can be entered, VLAN is used to distinguish the logic interfacing of protocol stack.
Application scenarios in second of scene, that is, the modified topological diagram of the embodiment of the present application (Fig. 5), small-sized PTN
Across metropolitan area network construction application, meanwhile, management passage also retains the encapsulation format of MCC, and outside adds last layer VLAN, this mode industry
Business uses UNI docking modes, management passage to use overlay modes.
Under this topology, the message format of each node can be as follows：
The management message A come out from NM server is route by the equipment (auxiliary configuration equipment) between A and A '
And encapsulation, it is deformed into A ' messages；C points are transparent to by MVLAN by Metropolitan Area Network (MAN), become D after minimizing PTN inter-process, most
CPU management is given on end.Response message is then corresponding reverse process.
It, can be by open most short between auxiliary configuration equipment and miniaturization access PTN device under this application scenarios
Heat source (OSPF, Open Shortest Path First) agreement carries out routing forwarding, and outer layer adds the encapsulation of MCC.?
There are multiple logic routing interfaces on the interface of auxiliary configuration equipment docked with Metropolitan Area Network (MAN), is distinguished by VLAN.
The shortcomings that this scheme, is that the logic interfacing number of OSPF is more, is got over to transmitting the impact of logic CPU of OSPF
Greatly.
The third scene still uses the topological diagram of Fig. 5, but management passage is no longer OVERPLAY patterns, but UNI moulds
Formula.
The message format of each node can be as follows：
It is by network management configuration IP and VLAN between auxiliary configuration equipment and miniaturization access PTN device under this scene
Correspondence forwarding list, rather than pass through routing forwarding.For example, the pipe where the miniaturization access PTN that IP is 192.168.1.2
