SK Telecom, the largest mobile operator in Korea with nearly 50 percent of the market share, will be building a high capacity leaf-spine based data center network leveraging VXLAN/EVPN for virtualization, scalability and availability, providing customers with 5G high-speed network services.

The Korean mobile operator commercialized its 5G service in December 2018 for the first time and intends to apply Mobile Edge Computing (MEC) for an efficient IT infrastructure expansion plan in line with its service expansion. Accordingly, in a bid to provide high-capacity data transmission services reliably, it reviewed introducing high-speed network switches capable of supporting 25GbE/100GbE or higher, as well as the existing 10GbE speed. Arista switch platforms are expected to become key elements of the network infrastructure as they would provide reliable services, efficient network management and real-time monitoring features.

Arista Networks is providing SK Telecom with universal spine and leaf network switches, combining routing and switching “to reduce complexity and significantly improve scale without compromising performance at speeds of 100+Tbps.” In addition, Arista’s network switches would enable functionality such as “100GbE aggregation, large routing tables, high resiliency, hybrid cloud traffic patterns, lossless connectivity and real-time monitoring in a single chassis, meeting the requirements of commercial, private and hybrid clouds.”

Arista EOS

“By installing Arista Networks’ network switches optimized for 5G in our infrastructure, we have been able to provide high-quality 5G services quickly and reliably to our customers,” said Se Wook Kim, Manager for SK Telecom’s Core Engineering Team of Infra Eng Group at ICT Infra Center. “Arista Networks also offers prompt and expert support services appropriate for our business characteristics, for which reliable service operation is essential. In the future, we intend to work together to proceed with network infrastructure upgrades in accordance with our 3G service expansion.”

At the core of Arista’s solution is Arista EOS (Extensible Operating System). This would help simplify network operations with single image consistency, Smart System Upgrade (SSU) and integration. Arista CloudVision would extend this approach by delivering a consistent telemetry and automation system for the entire network across private, public and hybrid clouds.

VXLAN/EVPN technology: WorldStream

Arista’ VXLAN/EVPN technology has also been adopted by Infrastructure-as-a-Service hosting provider WorldStream for example, a fast-growing provider of security-focused IaaS hosting solutions with more than 15,000 dedicated servers installed in its company-owned data centers in the Netherlands. The company recently announced a strategic technology partnership with Arista Networks, allowing WorldStream’s engineering teams to uniquely design its virtualized, elastic network on top of their extensive global network backbone – a backbone featuring a high-bandwidth capacity with 10Tbps available.

Once ready, the VXLAN/EVPN-powered WorldStream Elastic Network will provide organizations worldwide with a high level of control over comprehensive data center, network and cybersecurity features locally at the edges of the WorldStream network backbone. WorldStream’s R&D department expects the custom design of the new network to be ready Q1 2020 at the latest.
