[April 25, 2013] Deutsche Telekom selects Tail-f as provider of software-defined networking Tweet Apr 25, 2013 (Datamonitor via COMTEX) -- Deutsche Telekom AG, a provider of telecommunications services, has selected Tail-f Systems AB, a provider of network service programmability solutions, to deliver the key software components of its software-defined network, or SDN, in its TeraStream project. TeraStream's goal is to create an all-IP transformation to cope with exponential traffic growth while streamlining the delivery of network services in real time. With Tail-f's NCS (Network Control System) TeraStream is able to deliver this new networking model through a network-wide and service-aware unified application programming interface (API), Tail-f said. "We believe carriers can no longer afford to hard-code services into the OSS if they want to get to market quickly with new services," said Axel Clauberg, vice president, Aggregation, Transport, IP and Fixed Access, Deutsche Telekom AG. "The Tail-f NCS solution, with both services and the network modeled in a standardized high-level language, shortens time to market, increases vendor independence and dramatically improves the cost structure. This SDN solution is a key component in TeraStream's real-time OSS." "As a multi-vendor SDN solution provider, we are excited to partner with Deutsche Telekom to change the way network operations are being done," said Hakan Millroth, CTO of Tail-f Systems. "Tail-f has been driving standardization of network service programmability for a long time to reduce key pain points such as vendor dependence, lack of service innovation and high operating costs. The adoption of these standards by TeraStream and its network equipment providers will fundamentally change the networking industry." Tail-f Network Control System (Tail-f NCS) provides a new foundation for delivering a unified interface to all network devices and services. NCS leverages YANG (RFC 6020) and NETCONF (RFC 6241) - two standards that address service and device modeling and fail-safe mechanisms - to change network configurations, Tail-f added. Network services and devices are modeled in YANG, and their configuration states are centrally stored in NCS. NCS provides a declarative way to specify how a network service shall be applied to the network infrastructure. It provides a set of model-driven APIs, including publish-subscribe APIs, so that other systems can be kept in sync in real time. It applies all service changes towards the network as an atomic change set, the company concluded. http://www.datamonitor.com Republication or redistribution, including by framing or similar means, is expressly prohibited without prior written consent.
