Managing the ASON Protocol

After the ASON software is enabled, the default ASON protocols are configured for the NE. After the ASON topology is created, you can set again the ASON protocols you need to facilitate the management of ASON link resources and ASON services.

Precautions

NOTICE:

Usually, you do not need to modify the protocol configurations.
You can modify the protocol configurations when the ASON networking is a special one, or when a higher security is required.

Querying the LMP Discovery Type
You can query the overhead bytes that are used by the LMP for the system to automatically discover TE links. Currently only the D4-D12 bytes are used. They are used for the communication between NEs.
Disabling the LMP Protocol
Usually it is not allowed to disable the LMP except in the following two cases. One is when an ASON NE is connected with a traditional NE that is incapable of transparent transmission. The other one is when an ASON NE has an optical interface that does not connect any fiber. In these two cases, you can disable the LMP to release idle resources for a better resource allocation.
Disabling the OSPF Protocol
Usually it is not allowed to disable the OSPF protocol except in the following two cases. One is when an ASON NE is connected with a traditional NE that is incapable of transparent transmission. The other one is when an ASON NE has an optical interface that does not connect any fiber. In the two cases, you can disable OSPF to release idle resources for a better resource allocation.
Encrypting the OSPF Protocol
You can query and set the OSPF protocol authentication and encrypt the OSPF protocol to ensure the security of the ASON network.
Setting the OSPF TE Link Flood Threshold
The TE link flood threshold defines the frequency of the flood on the TE link. After the network fault is cleared, the TE link data changes for times as the NE data upload or synchronization is performed. When the change times reaches the threshold, the flood takes place on the TE link.
Encrypting RSVP
To ensure the security of the ASON network, you can encrypt the Resource Reservation Protocol (RSVP). The encryption operation needs to be performed for two neighboring NEs. Two neighboring NEs can implement protocol interworking only if the two NEs have the same authentication type and authentication key.
Creating Out-Fiber Control Channels
The out-fiber control channel realizes the interconnection between two ASON domains. You can use an Ethernet cable to connect two edge NEs of two ASON domains, and then manually create an out-fiber control channel on the Web LCT. In this way, the communication between the two ASON domains is realized at the control plane.
