Secundal viae reason mode is: one by one on the EOC headend with relevant informations such as the static pre-configured EOC head end IP of band external schema addresses.After EOC equipment was incorporated into the power networks, under the situation that the PON network link connects, the EOC head end sent the relevant informations such as IP address of oneself with the form of broadcasting packet at service channel.This information ONU can not handle, and directly passes through OLT; This message that also can terminate adds after the information such as relevant ONU IP address, receiving port that the form with broadcasting packet is transmitted to OLT on service channel, OLT this broadcasting packet that terminates.OLT is with the local MIB of this information architecture storehouse; Directly pass through the mode of OLT for ONU, OLT with the counter form of looking into the user's MAC address information of ONU port, carries out port locations by the OAM passage.OLT reports webmaster to information such as EOC head end IP address, port locations by snmp protocol, thereby finishes the automatic discovery and the port locations of EOC headend.Webmaster is finished status monitoring (perhaps finishing the state-detection of EOC head end by OLT), EOC head end and the service attribute of terminal and the configuration and the management of parameter to the EOC head end by snmp protocol.Thereby get through the EOC link channel, promptly finished developing and managing of PON+EOC passage.
This mode need be with relevant informations such as the static pre-configured EOC head end IP of external schema address, form with broadcasting packet sends to the PON network, OLT this message that terminates, and make up local MIB storehouse, OLT reports EOC head end information to give webmaster by snmp protocol, thereby finishes automatic discovery and the port locations and the follow-up configuration of EOC headend.
The problem of bringing of this mode is:
1) needs local out-band method pre-configured initiation parameter on the EOC headend, the close coupling degree between all departments of the increase operator service fulfillment flow process and complicated, and the management cost in increase O﹠M department's later stage.
2) the EOC head end send oneself in the mode of broadcasting packet initial information to OLT, OLT generally can be provided with speed limit to up broadcasting packet, therefore, there be possibility that abandons in this message, and causes the discovery procedure of EOC head end to extend; In addition, OLT need detect broadcasting packet one by one, has increased the weight of the processing burden of OLT greatly, makes OLT have the risk of reliability.
3) technical not every OLT supports the parsing to up broadcasting packet, and therefore, this way to manage is not of universal significance.
