The OTN bandwidth such as unicast 10G (gigabytes), 40G, 100G, 200G or 400G may be selected according to maximum stream flow in ground.Such as work as maximum
Flow is 9G, then the OTN bandwidth of unicast 10G may be selected.
Further, the first plane and the corresponding wavelength of the second plane can be according to actual needs using 40 waves or 80 waves
OTN system.
Further, step S20 includes:
Two OTN planes are arranged between any two website, are denoted as the first plane and the second plane respectively by step b；
The business radio frequency channel of odd wave is deployed in first plane by step c, and the protection radio frequency channel of the odd wave is deployed in
Second plane.
The business radio frequency channel of even number wave is deployed in second plane by step d, and the protection radio frequency channel of the even number wave is deployed in
First plane, to obtain first plane and the second plane of active and standby radio frequency channel each other.
Specifically, two OTN planes are set between any two website, are denoted as the first plane and the second plane respectively,
The business radio frequency channel of odd wave is deployed in the first plane, the protection radio frequency channel of odd wave is deployed in second plane, and will be even
The business radio frequency channel of number wave is deployed in the second plane, and the protection radio frequency channel of even number wave is deployed in the first plane, to obtain active and standby wave each other

The OTN system of face and the second plane is as shown in Figure 5 and Figure 6.In Fig. 5, in the first plane (plane A), surprise that overstriking is shown
The business radio frequency channel that number wave is plane A is the protection radio frequency channel of plane B (the second plane) without the even number wave that overstriking is shown；Fig. 6's
In second plane, even number radio frequency channel that overstriking is shown is the business radio frequency channel of the second plane, and the odd number radio frequency channel that no overstriking is shown is the
The protection radio frequency channel of one plane.In embodiments of the present invention, using radio frequency channel as Minimal Protective granularity.
It is understood that the first plane is principal plane for the first plane, the second plane is spare plane；It is right
For the second plane, the first plane is spare plane, and the second plane is principal plane.
In addition, after step b, the step S20 can also include:
The business radio frequency channel of odd wave is deployed in second plane, the protection radio frequency channel of the odd wave is deployed in described
One plane.
The business radio frequency channel of even number wave is deployed in first plane, the protection radio frequency channel of the even number wave is deployed in described

Indication Signal, alarm indication signal), OCI (Open Connection Indicator, disconnect alarm),
LCK (Locked, locking alarm) and SSF (Server Signal Failure, the alarm of service layer's Signal Fail).If monitoring
The optical signal of wavefront outputs default warning information in the first plane traffic radio frequency channel respective links, then by optical signal from first
The business radio frequency channel of plane switches in the protection radio frequency channel of the second plane.As long as it is understood that the first plane traffic radio frequency channel pair
Answer the warning information outputed set by any one in link, it all can be by the optical signal of the first plane from the business of the first plane
Radio frequency channel switches in the protection radio frequency channel of the second plane.If monitoring, the optical signal of wavefront is corresponding in the business radio frequency channel of the second plane
Default warning information is exported in link, then optical signal can be switched to directly to the guarantor of the first plane from the business radio frequency channel of the second plane
It protects in radio frequency channel.
Further, the default warning information it is optional be optical signal power be less than preset threshold when output, even examine
The power for measuring optical signal in the first plane traffic report respective links is less than preset threshold, then the low alarm letter of output power
Breath, will be in the protection radio frequency channel of optical signal switching to the second plane, wherein and preset threshold is arranged according to specific needs, this
Embodiment is not particularly limited preset threshold.
Further, if not monitoring, the optical signal of wavefront exports in advance in the first plane traffic radio frequency channel respective links
If warning information, then continue monitor wavefront optical signal whether outputed in the first plane traffic radio frequency channel respective links it is default
Warning information.
If some communication service needs 4 links, then the link of λ 1, λ 2, λ 3 and λ 4 as the communication service is distributed.Its
In, the business radio frequency channel of λ 1 and λ 3 protect radio frequency channel in the second plane in the first plane；The business radio frequency channel of λ 2 and λ 4 in the second plane,
Protect radio frequency channel in the first plane.If the business radio frequency channel of the corresponding key light fiber break of the first plane, λ 1 and λ 3 can switch to
Two planes protect radio frequency channel accordingly.λ 1 and 3 link of λ have the interruption of certain time length in this process, but due to λ 2 and λ 4
The radio frequency channel quality of link is unaffected, and therefore, for a user, user is can not to perceive λ 1 and 3 link down of λ to communication industry
The influence of business.In the present embodiment, interrupting duration can determine as the case may be, and such as interrupting duration may be 50ms (millisecond),
Or 40ms etc..It follows that influence of the radio frequency channel switching to business is reduced by two OTN planes active and standby each other of setting,
If being distributed evenly over the first plane and the second plane as business of the same race opens multilink, if the optical fiber event of the first plane
Barrier, radio frequency channel are switched in 50ms to the second plane, client side port may interrupting service, but during this, distribute originally
It is unaffected in the radio frequency channel of the second plane.
The present embodiment is each core site setting at least one by the way that at least two core sites are arranged in same city
A convergence website；The plane that two active and standby radio frequency channels each other are disposed between any two website is denoted as the first plane and the respectively
Two planes；If monitoring, the optical signal of wavefront exports default warning information in the first plane traffic radio frequency channel respective links,
By in the protection radio frequency channel of optical signal switching to the second plane, it is closer that one or more geographical location is converged by convergence website
Data center, convergence website pass through core site intercommunication with the farther away data center in other geographical locations as data center outlet
(such as some website farther out from core site, but from convergence website it is closer, then may be coupled to convergence website in, pass through the remittance
Poly- website is connect with core site, without being connected in core site), avoid the farther away data center in geographical location and core
The distance between center station point is too far and causes optical fiber used too many, reduce distributed more live data centers networking plan at
This, and by disposing OTN plane active and standby each other between any two website, improve distributed more live data centers networking
The stability of scheme link.
Further, OTN network-building method second embodiment of the present invention is proposed.
The difference of the OTN network-building method second embodiment and the OTN network-building method first embodiment is, OTN group
Network method further include:
Half link between any two website is assigned to first plane by step e, the other half link is assigned to
Second plane, the link after obtaining the distribution of any two website.
Step f carries out link aggregation to the link after the distribution of any two website, obtains aggregated links.
In embodiments of the present invention, the corresponding equipment of any two website can establish multilink by OTN.Wherein, should
Equipment can be interchanger or router etc..After any two website establishes multilink by OTN, by any two website
Between half link be assigned to the first plane, at this point, the corresponding radio frequency channel of the second plane is as protection radio frequency channel, i.e., for being assigned to
For half link in first plane, the first plane is as service plane, and the second plane is as protection plane；And it will be left
The other half link be assigned to the second plane, for the remaining half link being assigned in the second plane, the first plane is
Plane is protected, the second plane is service plane, the link after obtaining the distribution of any two website.
After link after obtaining the distribution of any two website, it is poly- that link is carried out to the link after the distribution of any two website
It closes, obtains aggregated links.Specifically, when carrying out link aggregation, the corresponding interface of multilink is configured to a group, the group
A corresponding interface, it is link aggregation interface that this, which organizes corresponding interface,.It is to want OTN plane during carrying out link aggregation
Both ends polymerize simultaneously.Specifically, link aggregation can refer to Fig. 7, in Fig. 7, be set as interchanger, be by website 1
A plurality of ethernet link between website 2 is polymerize.
At this point, if at most half links are shaken under aggregated links interface when the main optical signal in aggregated links is shaken,
The other half link can keep working normally, and link aggregation interface can keep connecting, i.e., link aggregation interface can keep UP (connection)
State is not at DOWN and (disconnects) state, overlying roaduay will not be caused by protocol convergence.
It should be noted that cross-site link can configure BGP (Border Gateway Protocol, borde gateway association
View) or the Routing Protocols such as OSPF (Open Shortest Path First, Open Shortest Path First).If based on mutually
Standby OTN plane, if not having member port under link aggregation interface, i.e. the corresponding device port of link aggregation interface is disconnected company
