Despite the rapid development of 3G, traditional TDM services will still be a source of lucrative profits for telecommunications operators for a long time, so PTN must have multi service carrying capacity. The end-to-end pseudo wire simulation (PWE3) technology emerged to meet this requirement. MPLS-TP adopts PWE3 circuit simulation technology to adapt to all types of customer services, including Ethernet, TDM, ATM, etc., and provides end-to-end, dedicated line level transmission pipelines.

As a business simulation mechanism, PWE3 essentially encapsulates business data with a special circuit simulation message header, carrying basic business attributes such as frame format information, alarm information, signaling information, and synchronization timing information of the business data in the special message header, in order to achieve the purpose of business simulation [4]

The end-to-end services in the PTN network are shown in Figure 2. PWE3 requires the establishment and maintenance of pseudo wires (PW) in the tunnels of packet switched networks (PSN). PSCCM22AAN 16418-5312 uses PW encapsulation to transmit business data at the operator’s edge devices (PE), while preserving the attributes and characteristics of the business itself as realistically as possible. For customer equipment, PW represents a link or circuit exclusively occupied by a specific business, known as a virtual circuit. The customer’s device (CE) does not perceive the presence of the core network and believes that the services being processed are all local services.
