The Group provides fixed-network, mobile communications, Internet, and IPTV products and services for consumers, and ICT solutions for business and corporate customers.

挑战
Deutsche Telekom faced the challenge of building a new, elastically scalable model for their core central-office data center optimized for performance, low latency, and cost. They needed to deliver IPv4 services to customers in a native IPv6 network and automatically provision IPv4 and other L4-7 services quickly and efficiently. The architecture had to comply with core ETSI NFV documents while maintaining simplicity and openness. The demand for broadband had exploded, and customers wanted always-on connectivity without paying a premium, driving average revenue per user (ARPU) lower. Traditional service delivery times were no longer competitive, requiring weeks or months to configure using conventional networking technologies.
解决方案
Deutsche Telekom partnered with A10 Networks to develop a carrier-grade, IPv4-over-IPv6 Softwire solution as a virtualized network function. A10 Networks’ software-based and API-driven architecture, commitment to open standards like OpenStack, and willingness to create innovative solutions were key to helping Deutsche Telekom develop TeraStream. TeraStream is an all-IP cloud-enabled network piloted at Hrvatski Telekom in Croatia, delivering all services, including voice, IPTV, and Internet access, as cloud services provisioned on demand. TeraStream uses OpenStack for cloud orchestration, allowing control over compute, storage, and network resources in its data centers. The network functions are virtualized to create customized communications services quickly. A10 Networks implemented LW4o6 in its A10 Thunder Series CGN, and TeraStream deployed vThunder as a virtual service. The Thunder CGN product line is part of the A10 aCloud Service Architecture, enabling cloud operators to dynamically provision Layer 4-7 tenant services while improving agility and reducing cost.

Case Study
Vodafone Hosted On AWS
Vodafone found that traffic for the applications peak during the four-month period when the international cricket season is at its height in Australia. During the 2011/2012 cricket season, 700,000 consumers downloaded the Cricket Live Australia application. Vodafone needed to be able to meet customer demand, but didn’t want to invest in additional resources that would be underutilized during cricket’s off-season.
