Embodiment 1
[0026] figure 2 It shows the implementation process of the data playback simulation method provided by Embodiment 1 of the present invention, with the recording terminal as the execution subject, and the details are as follows:
[0027] In step S201, the data packet is converted into an LAPS frame according to the link access procedure (Link Access Procedure-SDH, LAPS) protocol on SDH, and the data packet is an Ethernet frame.
[0028] In this embodiment, the recording terminal is an intelligent terminal for storing data, such as a monitoring device. The data packet is an Ethernet frame. The LAPS frame is a variant of the HDLC protocol frame, which can provide data link services and protocol specifications, and can specifically encapsulate the IP data packets that the SDH network needs to transmit so as to define the encapsulated Ethernet frames. boundary. The recording end converts the data packets into LAPS frames according to the LAPS protocol, and the data packets are ...
Embodiment 2
[0033] Figure 4 It shows the implementation process of the data playback simulation method provided by the second embodiment of the present invention, with the download terminal as the execution subject, and the details are as follows:
[0034] In step S401, download the valid data saved by the recording end, parse the valid data to obtain a restored data stream including the LAPS frame and the identification character.
[0035] In this embodiment, the recording terminal is an intelligent terminal for storing data, such as a monitoring device. The data packet is an Ethernet frame. The LAPS frame is a variant of the HDLC protocol frame, which can provide data link services and protocol specifications, and can specifically encapsulate the IP data packets that the SDH network needs to transmit so as to define the encapsulated Ethernet frames. boundary. The download end downloads the valid data saved by the recording terminal, parses the valid data to obtain a restored data st...
