What is the MSTP device?
The OptiX OSN serie intelligent optical transmission system (MSTP) developed by Huawei is the intelligent optical transmission equipment.
The OptiX OSN serie is of a “universal switch” architecture. That is, the OptiX OSN serie can be used in packet mode or in TDM mode. When used with the other equipment of Huawei, the OptiX OSN serie supports various networking applications, such as the pure packet mode application, hybrid networking application (overlay networking of the packet mode and TDM mode), and pure TDM mode application. By using a proper networking solution, the data service and conventional SDH service can be processed in the optimal manner.
The OptiX OSN serie transmits voice and data services on the same platform with high efficiency. It integrates the following technologies:
In packet mode, the OptiX OSN 3500 supports the following technologies:
- Multiprotocol Label Switching (MPLS)
- Multiprotocol Label Switching Transport Profile (MPLS-TP)
- Pseudo Wire Edge to Edge Emulation (ETH PWE3)
- TDM PWE3
- ATM PWE3
In TDM mode, the OptiX OSN 3500 supports the following technologies:
- Synchronous digital hierarchy (SDH)
- Plesiochronous digital hierarchy (PDH)
- Ethernet
- Asynchronous transfer mode (ATM)
- Storage area network (SAN)/Video
- Wavelength division multiplexing (WDM)
- Digital data network (DDN)

OSN 500 is a small but fully functional device that can basically meet the needs of small businesses, but other models of equipment have many business slots and can meet greater needs. Even OSN 7500 also has the function of wavelength division. Through the comparison of the above data, we know the similarities and differences of these MSTP devices, so we can choose the right product according to our needs.
