The rapid growth of mobile and cloud services, media streaming and social networking as well as fast emergence of new applications and services sets new requirements not only for ever-increasing network capacity, but makes it essential for operators to be able to adapt their telecom infrastructure and respond very fast to changing environment. At the same time an operator has to balance its efforts to accommodate new market needs and the essential task of providing high-quality services to existing business, which may also mean support of legacy applications and telecom technologies.
Packet Optical Transport based on MPLS-TP/Carrier Ethernet technologies provides an optimal solution to those challenges, offering efficiency and scalability of packet networks with performance, resiliency and carrier-class features on par with traditional TDM networks, support of various types of traffic and interfaces, combined with NMS-based centralized network management and OAM-based fault management and performance monitoring. This combination helps carriers to optimize capital expenditure and operational expenses, while maintaining high level of scalability, reliability, performance and security.
SDN/NFV strategy can be efficiently applied to MPLS-TP/Carrier Ethernet transport to achieve enhancement of network and service agility and further improve TCO.
