MSTP is a multi-service transport platform based on SDH. It inherits SDH's protection, recovery and OAM abilities and supports transmission of PDH, SDH, Ethernet, ATM, and other services. MSTP is the most extensive multi-service transport solution used to carry network applications.
Hybrid MSTP incorporates evolutions from the new generation of multi-service transport solutions. The Hybrid MSTP system uses a unified switching architecture that combines the transmission capacity of conventional MSTP models with the added packet transport capabilities found in the MPLS/MPLS-TP tech.
