IPv6-based OTN, PTN, IPRAN, SPN and PON network automatic deployment method

Abstract

The invention discloses an IPv6-based OTN (Optical Transport Network), PTN (Packet Transport Network), IPRAN (Internet Protocol Radio Access Network), SPN (Shortest Path Network) and PON (Passive Optical Network) automatic deployment method. The method comprises the following steps of enabling a target device to generate a global unicast address through an EUI-64 rule and enabling the relay deviceto receive an NDP message sent by the target device; sending the NDP report to a network manager or a controller; enabling the network manager to unblock the NDP message and obtain an device management IP; enabling the network manager to add a port, connected with the target device, of the relay device into the management vlan through an SNMP protocol; enabling the network manager to reply to theRouter Solidion message and sends the Router Solidion message to the target device through the relay device; connecting the controller with the target device through an SNMP (simple network management protocol) or a netconf protocol after receiving a Router Advertent message fed back by the target equipment; and after the controller is connected with the target device through a netconf protocol in the SDN network environment, configuring the IP and the port number of the controller are configured to the target device and enabling the target device to be connected with the openflow of the controller. Compared with the prior art, a DHCP is not needed, the system overhead in the IP distribution management process is reduced, the efficiency is improved, and the system stability and transparency are improved.

Description

technical field [0001] The invention relates to the field of digital communication, in particular to a method for automatic deployment of IPv6-based OTN, PTN, IPRAN, SPN and PON networks. Background technique [0002] Such as figure 1 As shown, in the prior art, a DHCP (Dynamic Host Configuration Protocol, Dynamic Host Configuration Protocol) method is used to allocate management IPs to each device. The network management or controller needs to synchronize the device IP and manufacturer information through the internal notification mechanism and DHCP service to establish a management connection from the controller to the device. [0003] However, the above method has the following disadvantages: 1. The device needs to exchange complex DHCP messages to obtain the management IP, which increases system overhead and reduces efficiency; 2. Using the DHCP service requires additional system resources, and at the same time The stability of the system is reduced to a certain extent...

[0003] However, the above method has the following disadvantages: 1. The device needs to exchange complex DHCP messages to obtain the management IP, which increases system overhead and reduces efficiency; 2. Using the DHCP service requires additional system resources, and at the same time The stability of the system is reduced to a certain extent (it is completely dependent on the DHCP service); 3. It is necessary to use the synchronization mechanism of the internal DC and DHCP service, which reduces the transparency of the system
