CCSA held the inaugural meeting of “next generation optical transport network industry and technology standards Promotion Committee (tc618)” on December 25, 2020. The meeting elected the leaders of “next generation optical transport network industry and technology standards Promotion Committee” at all levels. At the same time, it held the annual meeting of the new Generation Optical Transport Network Development Forum (ngof). At the meeting, ccsatc618 / ngof issued the “cloud era oriented” policy The white paper on high-quality dedicated line technology (2020 Edition) proposed five-star high-quality experience index of cloud network integration, defined the service quality experience requirements of cloud network integration from five dimensions of security, reliability, convenience, responsiveness and perception, and fully adapted to the needs of users in different industries in office system cloud, production system cloud and core system cloud. The release of the white paper will further support operators to build differentiated cloud network integration products and services, give full play to their network advantages, and realize unified cloud network management, so as to bring high-quality cloud network integration business experience to end industry users.

White paper on high quality dedicated line technology released to bring high quality cloud network integration business experience

Dr. Xu Yunbin releases white paper

In 2020, the epidemic will accelerate the popularization of business such as telecommuting and online education, and enterprise cloud will become the key to resume work and production. Gartner predicts that the global cloud computing market will exceed 350 billion US dollars in 2023. The white paper on Cloud Computing Development (2020) issued by China Academy of information technology also points out that the scale of China’s private cloud market will reach 79 billion yuan in 2020, an increase of 22.6% compared with that in 2019, and it is expected to reach 150 billion yuan by 2023. With the acceleration of cloud in the industry, the demands of industry users for cloud network integration products and services are constantly improving, especially for high-value industry users such as government affairs, finance, medical, industrial park, etc., who put forward clear index requirements for cloud security, network bandwidth, delay, reliability, isolation, self-management, etc., which puts forward severe challenges to the existing cloud network integration service products of operators Challenge.

Based on this, ngof cloud & dedicated line carrying working group proposed a five-dimensional service experience index system for cloud network integration, and focused on defining the highest five-star cloud network integration service experience index

Security: exclusive cloud / industry cloud service of grade III or above, and the dedicated line to the cloud is carried by L1 hard pipeline isolated private network;

Reliability: the service index of cloud network is 99.99%, which supports the active and standby cloud pools, and the reliability of dedicated line access service of the active and standby cloud pools reaches 99.99%;

Perception: when the router at the exit of user CE goes to the private line switch of cloud pool in one hop, the 100 km end-to-end opening delay is less than 1 ms, and the delay jitter is less than 10%, which is independent of the network load.

Responsiveness: cloud service supports day level opening, real-time fault response and hour level fault recovery.

Convenience: pre sales cloud business integrated ordering, cloud resources real-time visual, flexible adjustable, cloud services can be customized.

At the same time, the white paper compares the characteristics of MSTP / SDH, L2 / l3vpn, potn, osu-otn and other special line carrying technologies. The OTN based on OSU can carry the multi granular client side service access from 2Mb / s to 100GB / s. at the same time, based on the property of hard pipeline security isolation, it provides stable low delay, flexible and controllable ability, which can effectively match the differentiation of high-quality special line to cloud service Demand is the best bearer technology for high-quality cloud network convergence applications.

Dr. Xu Yunbin of ngof cloud & dedicated line working group pointed out: “cloud network convergence will accelerate the deep integration of optical network and cloud business, and build five-star cloud network convergence application with cloud light integration, which will be the core competitiveness of telecom operators to build differentiated cloud network services for vertical industries. Facing the future, ngof will work with upstream and downstream industries to promote the further innovation of quality cloud optical integration applications, bring high-quality cloud network services to many differentiated industry users, and promote the prosperity and development of global optical network technology and application industry. “

Ngof has been committed to promoting the prosperity and development of the optical network industry. The cloud & dedicated line carrying working group has carried out a series of in-depth studies focusing on quality dedicated lines. The white paper on high quality dedicated line technology for the cloud era has played a huge role in promoting the application development of optical network in the cloud era. Up to now, more than 60 provincial operators in China have released products related to OTN quality special line, which effectively supports the digital transformation needs of customers in government affairs, finance, medical, large enterprises and other industries. At the same time, its influence has further spread to Asia Pacific, Europe, Latin America and other regions, supporting overseas operators to launch localized OTN quality special line products.

CCSA has always attached great importance to standardization work, and always takes organizing and carrying out information and communication standardization activities as its mission, so as to make contributions to the development of national informatization and information industry. With the establishment of ccsatc618, ngof will also enter a new stage, which can give full play to its industrial and technological capabilities, and promote the continuous evolution and leading of China’s optical network industry by combining with CCSA’s advantageous industry and standard platform.
