Arista Networks Korea announced on the 15th that it has supplied '7500R' and '7280SR', deep buffer network switches that can effectively handle traffic surges such as network micro bursts, to improve the service quality of KT's big data infrastructure.

In line with KT's 5G-based digital transformation strategy, the importance of big data is growing, and the stability and operational efficiency of infrastructure systems have emerged as more important factors than ever.

KT's KT DS analyzed solution proposals from each vendor to ensure stable quality. After several months of field testing, it was finally decided that the network should be configured with deep buffer-based switches in a big data environment.

Accordingly, KT compared and analyzed the performance test results between vendors and confirmed that Arista's deep buffer switches, 7500R and 7280SR, maintain stable quality without service loss even when microbursts occur.

Arista's deep buffer switch has proven its excellence in most of its customers operating big data services around the world, and has been confirmed once again in KT's big data infrastructure in Korea.
The Arista 7500R is a Universal Spine platform that combines routers and switches to reduce complexity and dramatically improve scale, with no performance degradation even at 100+Tbps transmission speeds. Additionally, the 7500R provides 100GbE density in a single chassis, large routing tables, high resiliency, hybrid cloud traffic patterns, lossless connectivity, real-time monitoring, and more, meeting the needs of public, private, and hybrid clouds.

The 7500R is based on the intelligent network operating system, 'EOS (Extensible Operating System)', and provides non-blocking virtual queuing (VoQ) technology that can prioritize traffic according to settings, SSU (Smart System Upgrade), flexible integration with existing networks, and compatibility between new and old models.

The Arista 7280SR is a fixed-type switch and router, and is a universal leaf platform that complements the 7500R universal spine platform. The 7280SR operates based on the existing EOS, thereby reducing complexity and saving time required for certification, resulting in reduced operating costs. Additionally, Arista CloudVision can be used to automate and manage a company's entire network infrastructure.

KT Data Intelligence Team Manager Dong-hee Seo said, “Arista’s 7500R and 7280SR have significantly improved the stability of big data services without data loss even in situations where network traffic suddenly surges as a result of performance tests,” and “Arista’s CloudVision and Telemetry have enabled integrated network management, which has greatly improved work efficiency.”

Currently, KT is introducing Arista's 7500R and 7280SR to stably accommodate the traffic load generated from big data infrastructure, thereby increasing the work efficiency of administrators.

In addition, through Arista Telemetry, we can instantly collect and analyze network status, allowing us to quickly identify network operation status, such as the timing of momentary traffic surges and causes of load occurrence, and build a system for easy management.

Kim Se-jin, CEO of Arista Networks Korea, said, “In order to provide stable services, infrastructure that transmits big data must now address the ‘buffer’ that can accommodate sudden surges in traffic, in addition to managing the ‘bandwidth’ that accommodates average network traffic.” He emphasized, “The Arista 7500R is positioned as the optimal alternative for large enterprise customers that demand high performance by providing an integrated solution that integrates switches and routers that were previously used separately.”
