Embodiment Construction

[0035] The technical solutions of the present invention will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

[0036] In order to solve the problem that the ONU repeatedly restarts due to the abnormal handling of the existing initialization process, which will cause a large burden on the OLT in the DPoE system connected to it, the present invention provides a method for the abnormal handling of the initialization process, which mainly includes:

[0037] When the DPoE system fails to obtain the configuration file, the ONU does not restart, and the DPoE system initiates a TFTP request to the background management system;

[0038] If the TFTP request is timed out or exceeds the predetermined number of times, and the DPoE system still fails to obtain the configuration file, it will instruct the ONU to reset and restart.

[0039] That is to say, when the DPoE system fails to obtain the configuration file, it does not reset and res...

Abstract

The present invention discloses a method and system for abnormal processing in the initialization process. The method includes: when the passive optical network over Ethernet (DPoE) system in the management background based on the cable transmission data service interface specification fails to obtain the configuration file, the optical network unit (ONU) Without restarting, the DPoE system initiates a simple file transfer protocol (TFTP) request to the background management system; if the TFTP request is timed out or exceeds the predetermined number of times, and the DPoE system still cannot successfully obtain the configuration file, it will instruct the ONU to reset and restart. The present invention solves the problem that the ONU is repeatedly restarted due to the abnormal processing of the existing initialization process, which will cause a large burden to the OLT in the DPoE system connected to it.

Description

technical field [0001] The invention relates to the communication field, in particular to a method and system for abnormal handling of initialization process. Background technique [0002] The Ethernet Passive Optical Network (EPON, Ethernet Passive Optical Network) system based on the DOCSIS, DataoverCableServiceInterfaceSystem management background, referred to as the DPoE system, the system architecture is as follows figure 1 As shown, the system mainly consists of a background management system comprising a simple file transfer protocol (TFTP, Trivial File Transfer Protocol) server, a simple network management protocol management server (SNMP Manager, SimpleNetworkManagementProtocolManager), a system log server (SyslogServer), and a time server (TODServer, TimeofDayServer), DPoE system including virtual coaxial cable modem (vCM), optical line terminal (OLT, OpticalLineTerminal) and other equipment, DPoE optical network unit (ONU, OpticalNetworkUnit) and user terminal equ...
