China Mobile Guangdong and Huawei Deploy the First OTN P2MP Cloud Access Private Line

Jul 26, 2021

[Guangzhou, China, July 26, 2021] On July 25, the Guangdong branch of China Mobile (Guangdong Mobile) and Huawei took the lead in provisioning the OTN point-to-multipoint (P2MP) cloud access private line, providing low-latency and highly reliable differentiated cloud access experience for SMEs and helping them achieve digital and cloud-based transformation. This private line further diversifies the enterprise private line products of China Mobile.

In 2019, the State Council of China officially released the Development Plan for Guangdong-Hong Kong-Macao Greater Bay Area. This document specifies the plan to promote rapid economic development and embrace emerging services and demands in the Greater Bay Area, cultivating a hotbed of innovation and growing the capabilities of new industries. By the end of 2020, there were 53,000 national high-tech enterprises in Guangdong province. One result of this digital and cloud-based transformation is that these enterprises have higher requirements on the latency and packet loss rate of private lines.

With "Responsibility makes perfection" as its guideline, China Mobile strives to surpass itself and continuously provides premium communication services for enterprises and individuals. Following this guideline, Guangdong Mobile has always been committed to building premium basic communication networks for the Greater Bay Area. In 2018, Guangdong Mobile built the world's largest all-optical cross-connect network, including 81 OXC grooming hubs and implementing all-optical mesh and direct connections between nodes. Moreover, Guangdong Mobile has deployed over 2,000 OTN nodes to build a premium OTN private line network covering 21 prefecture-level cities in the province. This network is connected to Hong Kong and Macao operator networks as well as China Mobile's premium enterprise network to support fast private line access, providing enterprise customers with secure, on-demand, and flexible services.

The OTN P2MP cloud access private line solution launched by Guangdong Mobile and Huawei is an important piece in the existing enterprise private line product portfolio and meets the increasing quality requirements SMEs have for networking and cloud access private lines. By integrating OLTs and OTNs, this solution comprehensively converges gigabit access and all-optical networks, providing industry customers, such as SMEs, with a premium cloud access experience. This solution has the following advantages:

  • Fast network coverage: The OTN P2MP private line uses existing ODNs that have covered business buildings to implement fast coverage and provisioning of enterprise private lines.
  • Quality cloud access: OLTs innovatively use upstream OTN boards to transmit services over exclusive OTN channels. This prevents service congestion and ensures zero packet loss. In addition, innovative dual-channel isolation technology for service and management signals ensures that private lines achieve deterministic E2E low latency and provides premium cloud access experience for SMEs.
  • E2E smart management and control: This solution uses iMaster NCE, Huawei's management and control engine, to implement cross-domain management and control of OTNs and OLTs, fast E2E service provisioning, SLA visualization, and self-service bandwidth adjustment, offering self-service and e-commerce experience.

During the 14th Five-Year Plan period, the digital economy in the Greater Bay Area will develop rapidly. Guangdong Mobile will continue to increase their network quality and use wide-coverage OTNs to provide ubiquitous optical connections for various industries such as finance, healthcare, and education, as well as support business buildings. Together, this brings convenient, agile, and premium connections to facilitate the digital transformation of SMEs and promote the prosperity of the information society.
