Abstract
The invention discloses a communication management method and system based on intelligent optical network unit. When the system is on, the management function modules of its main server or backup server start to be initialized. The communication configuring modules built in the main server and the backup server also start to be initialized to automatically update the initialization configuring data corresponding to and connected with the client terminal of the intelligent optical network. The client terminal of the intelligent optical network automatically conducts the functional identification and initialization of the CPU control module and the internet-of-things interface module. According to the communication management method and system based on intelligent optical network unit proposed by the invention, a long-time TCP connection and fault-tolerance and correction mechanism between a modularized intelligent optical network and a management platform is maintained. With the management method, the requirement of the TCP on the number of the TCP interfaces can be effectively reduced; the number of the servers and the overheads of the servers can be reduced; the switching between the main server and the backup server is realized, so is the switching between the IP and the domain name. Further, as fault-tolerance processing is introduced, connection can recover automatically when a fault occurs to the intelligent device.
Description
Technical field
The present invention relates to intelligent management system, and in particular to a kind of communication management method based on ASON unit and
System.
Background technology
As social informatization process is being developed rapidly, various sensors, digitlization and intelligent equipment occur in us
The every aspect of life.Technical method and complexity more and more higher involved by this kind of information system, this requires manager
Method also will grow with each passing hour, and need the ability for giving management " thinking ".
Modular ASON unit light harvesting network technology, the informationization technology such as technology of Internet of things and embedded technology
, system module is more, in order to ensure systematic function under LAN and wan environment can efficiently and stable operation,
Need a set of special management method and system.
All as the server end of TCP, management server connects the modules of traditional mode managed devices as TCP
Each module of the client for connecing, management equipment and managed devices sets up TCP connections, due to the port numbers of management server
Limited, this mode wastes the port numbers of TCP connections, increased the expense of system.
Traditional mode is addressed by IP address, this mode on a local area network using having no problem, but in wide area
Probably due to the IP address of server-assignment is modified and causes mistake in net.
The content of the invention

(205) ASON client receives master server or standby server data；
(206) ASON client end closes socket sockets.
As shown in figure 3, when the establishment of socket, after the completion of binding, server end is added to prison the socket for listening to
In the filec descriptor set listened, generally, the maximum of the theoretical filec descriptor of a process is 1024.Select
All Files descriptor is monitored, judges whether server socket is readable, if readable receive new connection, if unreadable,
Continuation judges whether client file descriptor is readable, if readable, judgement receives return value, if return value is more than 0, connection
Set up, if return value is less than or equal to 0, restart connection procedure.
Step (3) master server or standby server addressing start automatic identification addressing system, and ASON client is write from memory
To recognize first select and search server using the mode of IP address, if after timer expired, still not finding server, can turn
And the mode of domain name is used, and server is searched, if now timer is also overtime, the mode of IP address is reused, iterative cycles.
