In ASON, realize that DCN mainly contains following three kinds of modes:
(1) in-band signalling mode (In-band), signaling message are embedded in the optical link or passage that carries data flow, and for example, the overhead byte that uses SDH is as signalling path.
(2) the inside and outside signaling method of optical fiber (In fiber, Out-of-fiber), signaling message are carried in the special-purpose passage, and separate with data channel, but are carried in the same optical fiber, for example, adopt wavelength dedicated or special-purpose TDM time slot as signalling path.
(3) the outer mode (Out-of-fiber) of optical fiber, signaling message is carried in the special-purpose passage, and outside the optical fiber that carries data channel.Specifically, it can be divided into dual mode again: a kind of is to adopt special optic fibre, carries two-way SDH in the optical fiber and connects, and signaling message is placed on the payload part transmission; Another kind is to adopt outside signaling network, for example adopts Ethernet.
In ASON, can realize the DCN of multitude of different ways usually, every DCN more alternatively need reconfigure.At present, traditional way is manually each communication entity to be carried out the DCN configuration, still, adopts above-mentioned way, and for a medium size network, because interstitial content is numerous, therefore, layoutprocedure is more time-consuming, and easy error.

The 4th step: network element is with outer control interface neighbours' configuration, so that outside band, can communicate news under the situation between each network element.
The 5th step: if front four goes on foot successfully, then return the response message of handover success,, then return the response message of handoff failure to the device of this execution mode if fail to device.
In this execution mode, this device also includes the switching command feedback and guarantees module, and it has the effect that guarantees reliability.For example; At sending module after network element sends switching command; Through the regular hour, if when receiver module is not received the successful respond message of a certain network element, sending module will issue switching command to this network element again; When sending module repeatedly sends switching command and receiver module does not receive that when responding, authentication module is provided with failure to user prompt to a certain network element.
Embodiment two:
As shown in Figure 3, it is the use sketch map of present embodiment.As scheme the device and the network element of visible this execution mode, wherein network element is among the ASON, i.e. the ASON network element.
During instruction button, the device of this execution mode issues the instruction that switches in being with to each network element in the user presses band.Handoff procedure is following:
The first step: input module is judged the user and is supressed instruction button in the band, confirms that the user is input as the in-band method type.
Second step: configuration generation module generates the required configuration data of in-band method type.
The 3rd step: sending module sends configuration data and assigns the switching command that switches in the band to each network element.
The 4th step: receiver module receives the response message that network element returns.
The 5th step: authentication module shows the switching result of each network element according to the response message of each network element to the user.
Be the respective action of each network element below:
