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.
Hybrid MSTP is fully compatible with existing MSTP networks and
delivers improved efficiencies in network O&M, providing the optimal
performance and cost-effectiveness to meet the demands of the
transformations in packet-based transmission over bearer networks.
According to data released Ovum, as of the second quarter of 2015,
Huawei ranked first in the optical network and MSTP/Hybrid MSTP
market worldwide. Huawei MSTP/Hybrid MSTP products and services are
used in 130 countries and regions worldwide.
