Description
Technical field
The present invention relates to the communications field, in particular to one kind connection method for building up and device.
Background technology
As Network is increasing to the demand of bandwidth and dispatching, optical-fiber network is progressively to optical transport network
Third generation digital transmission network evolution based on (Optical Transport Network, abbreviation OTN), optical transport network lead to
The dense wavelength division system for crossing photosphere provides the bandwidth of vast capacity, and (Optical is exchanged by the light-path data cell of electric layer
Data Unit, abbreviation ODUk) flexible dispatching, networking capability and protective capability are provided.Meanwhile by introducing automatic hand over
Optical-fiber network (Automatically Switched Optical Network, abbreviation ASON) concept is changed, forms management, control
Three system, transmission planes, make optical-fiber network more intelligent.
Foundation for ASON business in OTN equipment, all it is from the client side of first node from the point of view of transport plane
Mouthful arrive tail node client side port, client side signal generally comprise synchronous digital network signal, ethernet signal, OTN signals or
Signal on other high-speed interfaces, above-mentioned signal carry out electro-optic conversion (upper road) in first node, then carry out photoelectricity in tail node
Change on (lower road), so as to finishing service.However, for said process, the restriction ability of head and the tail node client side port (by
Constraint information represents) it must can unanimously ensure the normal operation of light-path and electric pathway business, as shown in figure 1, due to visitor
Family side ports are located at the edge of network, therefore, the link carried in above-mentioned client side port are referred to as into edge link.Based on difference
Conversion veneer type, consider following several scenes：
1) scene 1：Client side signal is converted into optical channel transmission unit (Optical by light repeat plate
Channel Transport Unit, referred to as OTUk) signal, into photosphere transmission；, it is necessary to meet following bar under the scene
Part：Only need to establish optical layer connection, the access point port of optical layer connection must determine that head and the tail node must possess consistent signal
Type, speed etc.；
2) scene 2：Multiple client side signals are converted into OTUk signals by converging plate, into photosphere transmission, at this
, it is necessary to meet following condition under scene：Only need to establish optical layer connection, the access point port of optical layer connection must determine, head and the tail
The client port of node must be corresponded to strictly, and signal type must be consistent；
3) scene 3：Client side signal intersects client's plate by electricity and is first converted into ODUk signals, is selected by electric cross exchange plate
Select electric cross link plate and be converted into OTUk signals, it is necessary to meet following condition under the scene：Need first to establish optical layer connection,
The access point port of optical layer connection it needs to be determined that, establish electric layer connection on this basis, head and the tail node must possess identical electricity
Cross over transition ability, the signal of optical layer connection must be consistent；
4) scene 4：If client side signal, by protecting veneer to carry out signal protection, head and the tail node must also possess phase
It just can guarantee that business is successfully established with protective capability.
With reference to above scene, restriction ability will at least include signal access capability, protective capability, customer side counterpart and correspond to light
Layer access point, electric crossing, optical layer connection end point wavelength bearing capacity, electric layer connection end points time slot bearing capacity etc..
Control plane can establish business with soft permanent connection and exchange connection two ways in ASON.It is soft forever to connect
It is the client port information that can determine head and the tail node by webmaster by network management system initiation connection foundation request to connect, but for
Scene 1,2,3 can not obtain photosphere access point automatically, can not also determine its protective capability for scene 4, that is to say, that by soft
It is permanently connected to establish the restriction ability that the mode of business know the edge link of head and the tail node.On the other hand, the company of exchange
It is to establish request to be initiated by User Network Interface (User-Network Interface, abbreviation UNI) by client device to connect,
This mode can not more know the edge link restriction ability of head and the tail node automatically.
From the foregoing, it will be observed that conventionally, as the constraint information of head and the tail node can not be known, so as to when establishing connection
It can not ensure that the constraint information for establishing the both sides of connection meets corresponding requirement, so, because constraint information is unsatisfactory for requiring, from
