C4L is now running its MPLS network coreTX in parallel with their existing Cisco network, a significant milestone in the rollout plan.
C4L has raised additional funding to deploy coreTX on new, privately owned dark fibre routes between key data centre locations across the UK, installing Juniper MX480 or MX960 routers at each PoP.
Having already migrated all external connectivity and upstream Tier 1 providers from their existing network to a new 100Gb dedicated fibre ring, C4L's capacity planning, stability, traffic management and DDoS mitigation strategies which were not previously available, are now live positioning them able to commence planning for full customer migration to coreTX.
It claims a new suite of diagnostic tools have closely monitored and seen no outages on the coreTX network, despite fibre failovers, site reconfiguration and various real and simulated network traffic events.
As well as creating several shorter paths for traffic and utilising all the available fibre to keep latency to a minimum, C4L state they have commissioned new fibre links, each with N+2 failover paths configured by default to ensure it is carrier grade.
Their aim is to provide levels of network stability, security and scalability that are in excess of both their current network and the connectivity market as a whole.
Simon Mewett, CEO of C4L, said: "As a result of some limitations in our initial rollout, we have creatively redesigned the network and taken important strategic decisions to raise the additional investment necessary.
"Although this inevitably caused a delay in rollout completion, I am pleased to confirm that coreTX will now be upgraded to a 100% Juniper network, removing all interoperability concerns between multiple vendors.
"coreTX has been thoroughly tested and proven, validating both our design and selection process and demonstrating that the Juniper MX core delivers a truly carrier grade network".
