Introducing COLT's Pan-European Switched Ethernet VPN
COLT Telecom Group plc has just unveiled a new managed service that promises to reshape how businesses move data across Europe. The service, a Switched Ethernet VPN built on Cisco’s optical transport platform, brings together two industry leaders in a way that delivers both speed and security to enterprises that demand reliable, high‑performance connectivity. Instead of offering a generic Ethernet bundle, COLT has engineered a solution that flexes to traffic spikes, supports any‑to‑any routing, and guarantees end‑to‑end encryption over a dedicated fibre ring.
At its core, the VPN leverages Cisco’s proven multiservice architecture to provide a burstable bandwidth experience. Businesses can purchase a baseline capacity - whether it’s 100 Mbps or 5 Gbps - and then tap into additional network resources when demand surges. The result is a service that feels like a dedicated link but behaves like elastic cloud bandwidth, a combination that is especially valuable for bursty workloads such as large data transfers, video streaming, or real‑time analytics.
Behind the marketing buzz is a clear, data‑driven story. Cisco collaborated closely with COLT’s research team to understand the needs of their shared customer base. Interviews and surveys revealed that enterprises were actively looking for a solution that could handle high‑throughput applications while remaining cost‑effective. The focus on burstable bandwidth directly responded to this insight, giving businesses a safety net during peak periods without locking them into an expensive flat‑rate plan.
Security is another pillar of the offering. Every packet travels over fibre rings that are isolated from the public Internet, and the service includes built‑in encryption. That combination mitigates the risk of data exposure while meeting strict regulatory requirements for sectors such as finance, healthcare, and government.
COLT’s CEO, Jean‑Yves Charlier, highlighted the company’s commitment to staying ahead of Ethernet technology. He said, “COLT is at the forefront of Ethernet technology developments and we intend to maintain our lead by continuous innovation.” This focus on innovation aligns with Cisco’s own strategy of providing services that “fully meet the needs of European enterprises.” The partnership has produced a service that feels both familiar to existing customers and fresh enough to attract new ones.
The launch follows a series of infrastructure investments that have expanded COLT’s fibre footprint across key European markets. By integrating the VPN into this network, COLT can offer a consistent, high‑performance experience from London to Warsaw, from Madrid to Oslo, and beyond. The geographic reach is not a secondary benefit - it’s a foundational element that gives the VPN its market‑shaping potential.
With the density of COLT’s network coverage, the company is well positioned to deliver a powerful value proposition to enterprises in Europe. Rob Lloyd, President of Cisco Systems Europe Middle East and Africa, said, “COLT’s Switched Ethernet VPN service gives European customers unparalleled price‑performance and service‑flexibility today. Wrap this up with COLT’s award‑winning reputation for customer service and support, and you have the potential of a truly ‘market‑shaping’ service.”
By offering any‑to‑any connectivity with high levels of security and the flexibility of burstable bandwidth, the VPN addresses a growing demand for low‑latency, high‑throughput links. Applications that need real‑time data backup, offsite disaster recovery, or data centre consolidation all benefit from a service that treats the network as a private, dedicated path. This capability is especially valuable for businesses that are already exploring hybrid‑cloud architectures and need a reliable bridge between on‑premises data centres and public cloud platforms.
In practice, the VPN is designed to be simple to deploy. Customers can sign up for the service through COLT’s online portal, specify their desired capacity, and then map their existing network onto the dedicated fibre ring. The service’s management interface exposes real‑time usage metrics, allowing administrators to see exactly how bandwidth is being consumed and when burst events occur. This visibility empowers teams to adjust their operations accordingly, reducing the risk of unexpected downtime.
In summary, COLT’s new Switched Ethernet VPN marries Cisco’s technical expertise with COLT’s expansive network and customer‑centric culture. The result is a managed service that delivers high‑performance, secure, and flexible connectivity to European enterprises. The combination of burstable bandwidth, any‑to‑any routing, and a dedicated fibre ring positions the VPN as an attractive choice for organizations looking to future‑proof their data movement strategies.
Technical Foundations and Network Design
The VPN’s architecture is built upon a stack of proven Cisco technologies that together provide reliability, scalability, and service assurance. At the base of the stack is the Cisco ONS 15454 Multiservice Provisioning Platform, which orchestrates traffic across the network and ensures that each customer’s bandwidth slice is isolated from others. The platform’s built‑in quality‑of‑service policies allow administrators to enforce traffic priorities, guaranteeing that mission‑critical applications always receive the bandwidth they need.
Above the ONS platform, the service uses Cisco’s Resilient Packet Ring (RPR) technology. RPR is a recent standard from the Institute of Electrical and Electronics Engineers (IEEE) that enables providers to carry voice, data, and video over existing Synchronous Optical Network/Synchronous Digital Hierarchy (SONET/SDH) fibre rings. Because RPR is designed to handle multiprotocol traffic efficiently, it reduces the need for separate circuits for each service type, lowering overall operational costs.
The choice of RPR is intentional. It leverages the robustness of legacy fibre infrastructure while adding the agility of packet‑based routing. By embedding the VPN traffic into the ring, COLT can guarantee low‑latency paths between any two points on the network, a feature that is especially valuable for real‑time applications like video conferencing and live data feeds.
To handle storage‑intensive workloads, the VPN incorporates Cisco MDS 9000 series Multilayer Storage Area Network (SAN) switches. These switches provide high‑speed, low‑latency paths for block‑level storage traffic, which is essential for customers that use the VPN to consolidate data centres or migrate large volumes of data to the cloud. The MDS series’ support for Fibre Channel over Ethernet (FCoE) means that SAN traffic can travel seamlessly over the same infrastructure that carries regular Ethernet packets, simplifying network design and reducing capital expenditures.
Complementing the SAN infrastructure are Cisco Catalyst switches, which offer robust Layer 2 and Layer 3 capabilities for edge routing and access control. Catalyst devices support a wide range of features - such as VLAN segmentation, port security, and link aggregation - that help customers segment their internal traffic and enforce strict access policies. The Catalyst lineup also supports advanced analytics, giving administrators visibility into network health and potential bottlenecks before they become critical issues.
When all these components work together, they form a network that is both resilient and flexible. The ONS platform’s provisioning engine can re‑allocate bandwidth on the fly, the RPR ring ensures low‑latency paths across Europe, the MDS SAN switches provide storage‑centric performance, and the Catalyst switches offer granular control at the edge. Together, they give COLT’s customers a single, cohesive environment that meets a wide range of business needs.
Beyond the core hardware, the VPN benefits from a suite of management tools that provide end‑to‑end visibility. Service-level agreements (SLAs) are monitored in real time, with dashboards that display latency, packet loss, and jitter metrics. If the network detects a deviation from expected performance, it can automatically trigger alarms, create troubleshooting tickets, and even re‑route traffic to maintain service quality.
For organizations that rely on strict compliance, the VPN’s architecture also offers robust logging and audit trails. Every packet is stamped with metadata that can be traced back to its source, enabling regulators to verify that data flows are compliant with privacy laws such as GDPR. The dedicated fibre rings also eliminate the risk of data leakage across shared media, a concern for highly regulated industries.
Because the VPN is built on open, industry‑standard protocols, it can integrate with a wide array of third‑party solutions. Whether a customer wants to use their own firewall, application delivery controller, or cloud‑based analytics platform, the architecture supports those choices without compromising performance or security.
Overall, COLT’s Switched Ethernet VPN demonstrates how a thoughtfully layered network can deliver both the speed of a private fibre ring and the flexibility of packet‑based services. The combination of Cisco’s ONS, RPR, MDS, and Catalyst technologies ensures that the VPN is resilient, secure, and ready to meet the most demanding enterprise workloads.
Enterprise Value and Future Outlook
From a business perspective, the new VPN unlocks several key advantages for European enterprises. First, the dedicated fibre ring guarantees predictable latency, which is critical for applications that cannot tolerate packet delays. For example, a financial trading firm that relies on millisecond‑level data feeds will find that the VPN’s low latency keeps its trading edge sharp.
Second, the burstable bandwidth model aligns costs with usage. Enterprises can maintain a baseline capacity that covers their regular traffic, then tap into additional bandwidth during seasonal peaks or large‑scale migration projects. This pay‑for‑what‑you‑use approach prevents the inefficiencies of over‑provisioning while still ensuring that critical workloads never suffer.
Third, the integrated security framework offers a seamless shield against external threats. Because traffic never traverses the public Internet, the risk of interception or tampering drops dramatically. For companies that handle sensitive customer data or intellectual property, this level of isolation can translate into compliance savings and reduced exposure to cyber risk.
Customers who use the VPN for data centre consolidation benefit from a unified transport layer that supports both LAN and SAN traffic. Consolidating multiple data centres over the VPN can reduce the complexity of inter‑site connectivity, lower total cost of ownership, and improve overall data center efficiency. The Cisco MDS SAN switches, for instance, enable high‑throughput block‑level replication, ensuring that data remains synchronized across sites with minimal latency.
The VPN also positions enterprises for a hybrid‑cloud future. By using the dedicated fibre ring as a secure conduit, organizations can move workloads between on‑premises data centres and cloud platforms without exposing traffic to the wider Internet. This architecture simplifies data migration strategies, reduces the need for VPN concentrators or MPLS circuits, and can accelerate time‑to‑value for cloud initiatives.
From a market perspective, COLT’s service taps into a growing demand for European‑centric connectivity solutions. The company’s extensive network footprint, combined with Cisco’s technological pedigree, gives it a competitive edge over providers that rely on older, less efficient routes. The partnership also demonstrates a willingness to co‑develop solutions that are grounded in customer research, reinforcing trust among enterprise buyers.
Looking ahead, the VPN’s architecture is designed to accommodate future growth. As bandwidth demands rise, the ONS provisioning platform can scale to support additional users without requiring a complete redesign of the network. Moreover, the RPR ring’s inherent resilience - thanks to its ability to route around failed links - ensures that service availability remains high even as the network expands.
The industry is also moving toward greater automation. COLT’s service already exposes APIs that allow customers to manage bandwidth allocation programmatically. This capability is a stepping stone toward fully automated, intent‑based networking that could adjust resources in real time based on predictive analytics.
In terms of competitive positioning, the VPN offers a unique blend of features that are difficult to replicate. While many providers offer dedicated circuits or MPLS, the combination of burstable bandwidth, any‑to‑any routing, and an isolated fibre ring creates a differentiated value proposition. For enterprises that cannot compromise on performance or security, the VPN is a compelling option.
In essence, COLT’s Switched Ethernet VPN delivers tangible business outcomes - reduced operational costs, enhanced security, and improved agility - while laying the groundwork for future digital transformations. By combining Cisco’s proven hardware with a customer‑centric approach, COLT provides a service that is ready to meet today’s challenges and tomorrow’s opportunities.
