Improved delivery, better visibility: How Accedian and VMware are working together to help CSPs navigate the 5G world
Adding a new dimension of visibility to the Cisco Full-Stack Observability portfolio with Accedian Skylight
Tools & Support
SK Telecom boosts capacity planning and improves operational efficiency with Skylight
Business issue
SK Telecom’s long-term technology goals revolve around applying big data to reliably assure performance of their network infrastructure and the services that run on it.
This involves:
- Using KPIs to proactively avoid user experience issues
- Detecting traffic microbursts
- Locating bottlenecks and using that information to improve network capacity
- Immediately identifying and detecting any network misconfigurations
- Optimizing fault failover to eliminate service downtime and improve network quality
These objectives had been identified as paramount to support SK Telecom’s business goals related to 5G, namely:
- Use service metrics to develop new revenue through targeted advertising, location- and situationally-aware applications, and on-demand video delivery using a subscription model
- Have network performance and agility underpin all services, from pre-5G mobile broadband, voice and video over LTE (VoLTE / ViLTE), through to new revenue sources targeted by their big data strategy
- Streamline and automate network management by coupling complete monitoring coverage with their SDN control infrastructure
To achieve all these objectives, SKT required a solution capable of:
- Per-flow measurements with microsecond precision
- Ultra granular, sub-second sampling
- One-way and two-way measurement capabilities
- Integrating into SK Telecom’s sophisticated, multi-vendor network and their custom-designed management and orchestration systems
Solution benefits
SK Telecom deployed Accedian’s Skylight. This multi-vendor compatible, standards-based solution centralizes a real-time view of network performance throughout the network. It also augments SK Telecom’s existing management system with real-time quality of service (QoS) and quality of experience (QoE) KPIs. Skylight enables SK Telecom to:
- Maintain control and optimize end-user experience through complete, network-wide QoS and QoE
- Consistently support standard monitoring protocols across multiple vendors’ network equipment
- Support next-generation networking using automation, programmability and dynamic service chaining and deployment
- Drive the orchestration layer using real-time metrics
Business value and ROI
Deploying Skylight nationwide generated some impressive positive outcomes, including:
- Increased operational efficiency through accurate, localized information about network segments where issues originate or occur
- Effective capacity planning for special events and locations, such as festivals or sports stadiums
About SK Telecom
Established in 1984, SK Telecom is Korea’s largest telecommunications company with more than 28 million mobile subscribers, accounting for about half the market. Its notable achievements include the following highlights: world’s first company to commercialize CDMA and HSDPA networks, provider of Korea’s first LTE service (launched in 2011), the world’s first mobile carrier to commercialize 225 Mbps LTE-Advanced (2014), and successful commercialization of 300 Mbps tri-band LTE-A carrier aggregation.
“Best-possible quality of service and quality of experience is at the heart of our reputation and our business. This is particularly important as we continue to extend our network towards 5G, and to expand coverage with small cells, making the need for 24x7 end-to-end network visibility critical. Accedian’s performance monitoring solutions make this possible.”
