BT’s new automation platform accelerates journey to SD-WAN

BT has launched a new Service and Network Automation Platform (SNAP) designed to help customers innovate using SD-WAN and network functions virtualisation (NFV) technologies.

The unique platform sits at the heart of BT’s global network and leverages SD-WAN controllers from Cisco and Nuage Networks. SNAP also works with Cisco’s Network Services Orchestrator. SNAP uses open source software and industry-standard languages including YANG for network modelling and TOSCA for service definition and VNF service chaining. Control commands can now cascade through BT’s systems taking effect within minutes, something that previously could take weeks.

BT said it plans to extend orchestration from its core network to major third-party cloud data centres and all the way into customers’ local area networks (LAN) and data centre LANs (DC-LANs). This will provide end-to-end applications visibility, control and configuration from customers’ laptops and devices through to servers in the cloud.

BT has pooled its SD-WAN and NFV expertise and key skills into a new Centre of Excellence (CoE). The CoE supports the full life cycle of customers’ SD-WAN or NFV services, collaborating across design and deployment to operations. The integrated team is backed with a programme of investment in training and tools in areas such as YANG, Netconf and TOSCA — new skills that are in very short supply.

Keith Langridge, vice president of network services at BT, said: “We’re investing to make it easier for our customer to take advantage of the latest networking technologies and cloud. Our new Service and Network Automation Platform and Centre of Excellence help customers tap into our wealth of know-how and experience in SDN and NFV. We have created a unique environment in which customers can deploy the latest software-defined services alongside their underlying network technologies. This transforms their experience of the journey to SD-WAN and makes the promise of software-defined services an operational reality.”

BT first to deploy Nokia's 7750 SR-s platform

BT will be among the first operators in the world to deploy Nokia's 7750 Service Router (SR)-s platform to boost backbone network capacity in preparation for the continued rise in residential and mobile traffic driven by the traffic demands of FTTP and 5G.

The Nokia 7750 SR-s will augment the existing Nokia 7750 SR and 7950 Extensible Routing System (XRS) it BT's network. Financial terms were not disclosed.  Nokia described the deal as an exclusive agreement.

Howard Watson, BT Group CTIO, said: "BT's FTTP footprint is growing on a daily basis, and we are launching 5G this year in the busiest parts of 16 of the UK's busiest cities. These technologies create an amazing customer experience, and drive people to watch more, play more and share more. We have to stay ahead of the massive traffic growth that this will bring, and Nokia are a key part of that, giving us the capacity and automation that we need."

Sri Reddy, Co-President of IP/Optical Networks at Nokia, said: "Nokia's 7750 SR-s platform, based on our FP4 silicon, will offer BT's network the enhanced capabilities and automation needed to address continuously mounting capacity demands as it moves toward 5G. Our exclusive partnership will allow BT's converged core network to grow, and move to a programmable, insight-driven network architecture, creating a platform for BT's growth to continue as demand for its services in FTTP and 5G expands."

The Nokia 7750 SR-s is powered by the company's multi-terabit network processor silicon (FP4).

Nokia Unveils its Next Gen IP Routing Engine

Nokia unveils its fourth generation network processing silicon for powering the first petabit-class core IP routers.

The new FP4 silicon, which comes six years after the preceding FP3 chipset was announced, offers 2.4 Tb/s half-duplex capacity, or 6X more capacity than the current generation 400 Gb/s FP3 chipset. The FP4 will support full terabit IP flows. All conventional routing capabilities are included. Deep classification capabilities include enhanced packet intelligence and control, policy controls, telemetry, and security.


The FP4 could be used to provide an in-field upgrade to Nokia’s current line of core routers and carrier switches. It will also be used to power a new family of 7750 SR-s series routers designed for single-node, cloud scale density. In terms of specs, the SR-s boasts a 144 Tb/s configuration supporting port densities of up to 144 future Terabit links, 288 400G ports, or 1,440 100GE ports. Absolute capacity could be double for a maximum of 288 Tb/s configuration. It runs the same software as the company’s widely-deployed systems.  The first 7750 SR-s boxes are already running in Nokia’s labs. First commercial shipments are expected in Q4.

Nokia is also introducing a chassis extension option to push its router into petabit territory. Without using the switching shelf concept employed in the multi-chassis designs of its competitors, Nokia is offering the means to integrate up to six of its 7750 SRS-s routers into a single system. This results in 576 Tb/s of capacity, enough for densities of up to 2,880 100GE ports or 720 400G ports.

Quantum Network Link goes live in UK

The world’s first commercial-grade quantum test network link is now operational between the BT Labs in Suffolk and the Cambridge node of the UK’s new Quantum Network, which is being built by the Quantum Communications Hub, a collaboration between research and industry, supported by the UK’s National Quantum Technologies Programme. The new connection stretches from BT’s Adastral Park research campus near Ipswich in the East of England, to Cambridge. The wider UKQN network then extends onward over the National Dark Fibre Infrastructure Service to Bristol in the South-West.

The link uses over 125km of standard BT optical fibre between Cambridge and Adastral Park, with BT Exchanges acting as ‘trusted nodes’ along the route. The link will carry both quantum and non-quantum traffic; the QKD technique shares data encryption keys via an ultra-secure quantum channel over the same fibre that carries the encrypted data itself.

ADVA confirmed that its FSP 3000 is playing a key role in the new UKQNtel transport network secured by quantum key distribution (QKD). As part of an initiative led by QComm Hub, and with partners BT, ID Quantique and the universities of Cambridge and York, ADVA has constructed a QKD link capable of carrying classical and quantum channels on the same standard, installed fiber.

“Today’s launch is a significant step for network security. As well as being the UK’s longest QKD-protected link able to transmit both classical and quantum applications, this solution breaks new ground by showcasing the readiness of quantum cryptography for real-world transport,” said Professor Tim Whitley, MD, research and innovation, BT. “Our team has been at the forefront of developing quantum-secure telecoms infrastructure from day one. We’ve succeeded in taking the technology from PoCs in the lab to real-world demonstrations. Now we’re closing in on enabling customer trials and plans for full-scale deployments. Soon mission-critical networks will be protected even from cybercriminals intent on harvesting information today in order to decode and exploit it tomorrow.”

BT employs ADVA's precision synchronization for 5G

BT is deploying ADVA's Oscilloquartz synchronization technology to bring 4G coverage to previously underserved areas and begin the rollout of 5G services across the UK. The new synchronization solution is deployed nationwide in 10 core time base sites, 106 metro time sites and close to 1,000 Tier 1 sites at the network edge.

Prior to this deployment, BT’s timing network was based purely on frequency synchronization.

ADVA said its Oscilloquartz enables BT to distribute stable and accurate phase and time-of-day information. The new synchronization network is built on the OSA 5430 and OSA 5440 and integrated with ADVA’s network management solution. The technology provides the sub-microsecond accuracy required for next-generation mobile applications together with hardware redundancy for unbeatable resilience.

ADVA’s modular grandmaster clocks support PTP, NTP and SyncE over multiple 10Gbit/s interfaces. They provide high levels of accuracy and holdover performance in case of GNSS outages, meeting ITU-T G.8272 primary reference time clock (PRTC) requirements. Comprehensively managed by ADVA’s network management solution, the technology is also ready to combine with its advanced cesium clocks for enhanced PRTC levels of stability, accuracy and reliability even without GNSS.

“Adding robust, highly accurate phase and time synchronization unleashes the full potential of our network. Not only does it empower us to deliver the services our customers demand today but it’s also the key to our 5G aspirations,” said Neil McRae, chief architect, BT Group. “The OSA 5430 and OSA 5440 offer the robustness of hardware redundancy together with the scale we require to meet tomorrow’s needs. Their modular design also means that our network is ready to support future timing technologies without further upgrades. Our close partnership with ADVA’s team and their Oscilloquartz timing experts is another crucial factor. It’s been clear from day one that they understood our core requirement for a flexible architecture with superb levels of precision and protection.”

“Phase synchronization has been a long-term development in international standards, and ADVA has actively contributed to that process,” commented Mike Gilson, standards contributor and technical specialist, timing and synchronization, BT Group. “By incorporating these capabilities in a flexible, high-performance solution, ADVA has created a synchronization network ready for the demands of 5G connectivity. We‘ve been very pleased with the way ADVA’s team have worked closely with us to fulfill not only our initial requirements but also provide a foundation for the future.”

“Bringing these levels of accuracy and resilience to BT’s mission-critical synchronization network is a real milestone. Achieving phase synchronization is a major challenge but with our uniquely flexible, high-capacity technology and the dedication and experience of our team, we’ve been able to handle all of that complexity on BT’s behalf and provide the ideal solution for its needs and ambitions,” said Sarah Mendham, senior director, sales, ADVA.
