Research On SPTN Control Network And Implementation Of DHCP On Equipment

The government-enterprise private line service and the wireless back-transmission service are the two high-value services of the operator's PTN network,and the government-enterprise private line service is generally carried by the miniaturized PTN equipment.With the maturity of PTN technology and the rise of SDN/NFV technology,operators have put forward new demands on PTN networks,especially in the field of government and enterprise special lines,how to realize the centralized intelligent management and control of the government-enterprise private network,the rapid opening and adjustment of the featured business,and the open innovation of the new business of the government and enterprises in the future have become the problems that operators need to solve in the operation of the customer.In order to solve the painful points of the opening and running of government and enterprise private line services,the introduction of SDN can realize the opening of network capabilities in the government and enterprise private line business areas,create a new business experience,and realize efficient operation and maintenance of the network.Aiming at the strategy of miniaturized PTN network SDN proposed by operators,especially the implementation of S-SCN function required by operators to support interoperability between different manufacturers.This paper focuses on the research of SPTN control network,and completes the design and implementation of the key module DHCP Client of SPTN equipment.By setting up a real test environment in the laboratory,operating the domain controller DC to complete the functional test of the DHCP Client module for SPTN equipment.Miniaturized SPTN equipment completes the test of different manufacturers interoperability in the pilot network,and extensively and deeply realizes the interoperability among different manufacturers in the control domain,which lays a foundation for the commercialization of SPTN equipment and SPTN network engineering.
