Description
Technical Field
The invention relates to a network communication technology, in particular to a rapid management system based on an OTN channel.
Background
The OTN is a next-generation backbone transport network based on a wavelength division multiplexing technology and organized in an optical layer. OTN passes through a new generation of "digital transport" and "optical transport" as specified by a series of ITU-T recommendations, g.872, g.709, g.798, and so on. The OTN solves the problems of weak scheduling capability, networking capability, protection capability and the like of the traditional WDM network wavelength-free/sub-wavelength service. At the edge layer of the OTN network, signals of different systems are encapsulated into a frame structure in a unified OTN system with rich overhead, and based on the frame structure, the unified operation, management and maintenance of the WDM whole network based on the OTN system are realized.
The OTN technology (OTH in the electric domain and ROADM in the optical domain) solves the problems that the cross grain of the SDH based on VC-12/VC4 is smaller, the scheduling is more complex and the requirement of large-grain service transmission is not adapted, and partially overcomes the defects that the fault location of a WDM system is difficult, the networking capability is weaker in a networking mode taking point-to-point connection as a main mode, and the provided network survivability means and capability are weaker;
therefore, a fast management system or method based on OTN channel is also needed to be solved urgently.

an access type OTN management and control system; the access type OTN management and control system supports DHCP Server service, has IP address allocation and planning strategies of the access type OTN, and allocates random IP addresses for the access type OTN equipment by adopting a DHCP protocol.
Further, the method for the access-type OTN management and control system to obtain the IP address of the access-type OTN device is that the access-type OTN device and the access-type OTN management and control system obtain the IP address of the device in a NETCONF call home manner through a standard RFC 8071 mode.
Still further, the access type OTN management and control system has a DHCP server capability, or is separately deployed from a DHCP server device.
Particularly, when the access-type OTN management and control system is separately deployed from the DHCP server device, the access-type OTN management and control system establishes a NETCONF connection with the access-type OTN device in such a manner that the access-type OTN management and control system manually initiates establishment of a NETCONF connection with the access-type OTN device or automatically establishes a NETCONF connection with the access-type OTN device through a fixed NETCONF user name and password.
In addition, when the access type OTN management and control system is separately deployed from the DHCP server device, the method for the access type OTN management and control system to obtain the IP address of the access type OTN device is to inform the DHCPserver device of the IP address of the management and control system device after the DHCPserver device completes the IP address allocation of the access OTN device.
Further, the office-side OTN device is a metropolitan area network OTN device or a government-enterprise trunk OTN device.
Still further, the process of acquiring the own IP address by the access OTN device includes the following steps:

Detailed Description
The invention will be further described in detail with reference to examples of embodiments shown in the drawings to which, however, the invention is not restricted.
As shown in fig. 1 and 2, a fast management system based on OTN channel includes:
local side OTN equipment; the local side OTN equipment supports the DHCP Relay function, completes the basic configuration of the DHCP Relay and configures the Relay agent of the IP address of the DHCP Server;
an access-type OTN device; the access type OTN equipment adopts GCC2 through GCC default configuration, and simultaneously can select GCC0, GCC1, GCC2 and any combination to communicate with local side OTN equipment in a dialing mode; the access type OTN equipment is used as a DHCP Client, and the distributed ip address is a management address;
an access type OTN management and control system; the access type OTN management and control system supports DHCP Server service, has IP address allocation and planning strategies of the access type OTN, and allocates random IP addresses for the access type OTN equipment by adopting a DHCP protocol.
The access type OTN equipment obtains the IP address flow as follows:
1) the access type OTN equipment is communicated with metropolitan area network OTN or government and enterprise trunk OTN equipment through a default GCC channel (GCC 2) to establish a PPP link;
2) CPE OTN comes out of the field and configures default IP address (e.g.: 192.192.192.192, or generating a temporary IP address from the sequence number SN of the CPE OTN);
3) the access type OTN is used as a DHCP Client to send a broadcast DHCP request message on a PPP link at regular time to acquire an IP address of the access type OTN;
4) after receiving the broadcast message of the DHCP Client, the metropolitan area network OTN equipment or the government and enterprise trunk OTN equipment converts the broadcast message into a unicast message and forwards the unicast message to the access type OTN management and control system;
5) and the DHCP Server service of the access OTN controller allocates an IP address and a default gateway (static route) for the access OTN equipment according to the IP address planning principle of the CPE equipment, and returns a response DHCP message to the access OTN.
6) The DHCP Server can set the IP address of the controller as a default DNS IP address, and the default DNS IP address is carried (selectable) in the DHCP response message;
7) receiving the DHCP Reply message of the access type OTN controller by the metropolitan area network OTN equipment or the government and enterprise trunk OTN equipment, and then forwarding the DHCP Reply message to the access type OTN equipment;
8) and the access type OTN equipment sets an IP address and a default gateway according to the corresponding response message.
The management and control system should have the capability of planning the IP address and set the IP address allocation rule for the DHCP server.
Alternative schemes for acquiring the IP address of the equipment by the management and control system are as follows:
the first scheme is as follows: the DHCPserver informs the IP address of the management and control system equipment after completing the IP address allocation of the OTN access equipment;
scheme II: the OTN access equipment and the management and control system can acquire the IP address of the equipment in a standard RFC 8071 mode by adopting a NETCONF call home mode.
The management and control system can have DHCP server capability and can also be deployed separately from the DHCP server.
The management and control system and the equipment establish NETCONF connection mode as follows:
the first method is as follows: the management and control system can manually initiate the establishment and access of NETCONF connection of OTN equipment
The second method comprises the following steps: the management and control system can automatically establish NETCONF connection with the accessed OTN equipment through a fixed NETCONF user name and password.
After the access type OTN equipment acquires the IP address of the access type OTN equipment, the management and control system manages the access type OTN equipment in a large area mode as follows:
a. the access type OTN equipment actively initiates the establishment of TCP short connection to a management and control system after acquiring the IP of the access type OTN equipment and the address of the management and control system through DHCP; the management and control system monitors by using a 4334 port as a default of the server, and the monitoring port used by the management and control system is configurable.
b. After the TCP connection is successfully established, the access type OTN equipment sends an authentication plaintext message to the management and control system, wherein the message format is plain text, single line and UTF-8 encoding.
c. After receiving the message, the management and control system adds a prefix "Received:" to the original message, and immediately returns to the client, and disconnects the TCP connection (the management and control system actively tries to disconnect the connection).
d. If the device fails to establish a TCP connection with the port of the policing system 4334, the device should adopt a certain reconnection mechanism, such as retry once every few minutes and retry 3 times. Even without a reconnect mechanism, at a minimum, it is guaranteed that a device reboot or power-up will trigger the action of resending the TCP message. If the Received feedback message is Received, the TCP message does not need to be sent later unless the IP is changed. TCP messages can occur unconditionally if the device does not have the capability of historical IP comparison
e. After the above steps, a so-called CALL HOME process is completed, and the following steps are a process of starting normal netconf connection establishment, and the direction is that the management and control system actively connects the device
f. The management and control system uses the information in the message, and after the verification is passed, the management and control system tries to establish a new netconf connection with the port of the device 830. If the TCP message does not contain the key ID, the default user name password is adopted to connect the equipment, and if the TCP message contains the key ID, the user name password appointed by the equipment is used to connect the equipment
g. After successful connection, the management and control system modifies the netconf user password through the modifyUserPassword interface (only for the case of using the default user name password).
And after the management and control system acquires the network element information, all external management and control ports are closed through the setMcPortStatus interface.
The above-mentioned embodiments are only for convenience of description, and are not intended to limit the present invention in any way, and those skilled in the art will understand that the technical features of the present invention can be modified or changed by other equivalent embodiments without departing from the scope of the present invention.
