In mobile backhaul networks dominated by SDH technology, exclusive rigid transmission pipelines are provided for services. Although PSCCM22AAN 16418-5314 ensures high reliability of transmission, from another perspective, treating different types of services equally is also a waste. For example, for voice services with high real-time requirements and ordinary internet services, the two have completely different requirements for network transmission. PTN can perceive business characteristics and provide just the right services, achieving on-demand allocation and benefiting each other. The most economical way for telecom operators is to provide just the right service for different business flows with different requirements, especially in the context of a significant increase in bandwidth demand.

The OAM mechanism of PSCCM22AN 16418-5314 basically inherits the OAM idea of SDH, providing hierarchical alarm and performance management for segment layer, tunnel layer, and pseudo line layer. By supporting hierarchical OAM, faults in PTN network can be quickly located, and network performance can also be detected, including packet loss rate, latency, etc. [5]

The OAM message encapsulation format specified by ITU-T for T-MPLS [6] is shown in Figure 3. PSCCM22AAN 16418-5314 also uses MPLS encapsulated label messages for OAM signaling messages at various levels. In order to distinguish between OAM signaling messages and user business data messages, a special label is defined: 14, which is used to identify OAM signaling messages. By defining a series of OAM protocol packets, G.8114 has implemented a rich variety of OAM functions.
