Huawei Releases White Paper on Key Technologies in Open Optical Transmission Systems
Network openness calls for opening up and standardizing NBIs to the maximum extent possible
[Los Angeles, USA, March 23, 2017] Huawei has released a White Paper on Key Technologies in Open Optical Transmission Systems (‘White Paper’ for short) at OFC 2017. This White Paper elaborates on the industry's urgent requirements for network openness and major challenges, and proposes opening up interfaces at the control layer and implementing system integration at the transmission layer.
Optical networks are facing significant changes, including increasing demands from new services such as 4K/8K video, VR/AR, cloud computing, 5G, and data center services, as well as ever-changing customer requirements. Communication networks need to provide high performance and sufficient openness to enable flexible, intelligent, and diversified service deployment.
IHS undertook a survey to assess whether telecom operators are willing to use open line systems. According to the survey result, the industry is trending toward open network architecture. Telecom operators are in urgent need of network openness due to the following:
- To Quickly Adopt the Latest Technologies
- User-defined Networks, Fast Service Provisioning
- Lower OPEX
According to the White Paper, because optical networks are highly complex, fully opening up the physical layer makes system integration difficult, brings risks to system stability, reduces transmission performance, and increases OPEX. Operators also need to ensure the overall network performance and reliability.
The White Paper summarizes that all parties in the industry can maximize their capabilities when vendors integrate bottom-layer optical transmission systems and operators control upper-layer networks. In this case, operators can gain maximum network autonomy without compromising system performance and stability.
Based on the existing standards and technologies, Huawei promotes software interface standardization to connect bottom-layer transmission systems and upper-layer control systems. This allows services on different vendors' networks to interconnect and interwork with each other and to be freely dispatched, achieving network openness.
Based on open network architecture, Huawei’s CloudOptiX solution enables multi-vendor inter-domain service interconnection and interworking and helps operators to optimize network configurations and reduce OPEX. The solution also integrates the latest technologies in both the electrical and optical domains to guarantee the stable, reliable, and sustainable evolution of bottom-layer transmission systems.
It accelerates building an open network ecosystem and helps operators fully cloudify their networks to achieve digital transformation, build future-proof high-bandwidth, low-latency, open, and intelligent transport networks, and efficiently support various new network services.
