With the successful application of DSL technology, the gradual popularization of FTTH technology, and the evolution
from traditional network to NGN, the trend of IP business bearing has been formed. In the future, the optical
transmission network of the entire business operations will be primarily responsible for the IP / Ethernet traffic
transmission, the optimization of the characteristics of data flow in groups, and will develop in a direction of smart,
integrated, broadband, efficient and reliable packet transmission technology (PTN). The PTN based on T-MPLS
technology, supporting all types of business (Ethernet, IP / MPLS, FR, ATM, TDM,...), simultaneously supporting
general users (wired / wireless) and commercial users in various types of business development, would become a new
generation of converged networks of PTN platform. This article analyzes the crucial technologies of PTN in respects of
the T-MPLS system of the framework agreement, the hierarchical structure, the network model, operational capacity,
protection switching mechanism, etc, and puts forward a PTN-building program facing the entire business operations.
