More than 95 percent of the world’s intercontinental electronic communications traffic travels across undersea cables. Bandwidth is forecast to grow at more than 40 percent CAGR for the next several years in all regions.

With these growth figures in mind, there are three core challenges in managing your submarine network assets:

  • How can you keep up with voracious global bandwidth growth?
  • How can you protect terabits of traffic and avoid outages that come from faults?
  • How can you protect your revenues and margins while combating ongoing price erosion?

These three challenges might seem in opposition to each other—and solving them might be a daunting task. But Ciena has created the GeoMesh Extreme architecture to directly address these challenges.

Ciena's GeoMesh Extreme has four building blocks:

  • Switching: 5430 Packet-Optical Platform; 6500 Family; 8700 Packetwave® Platform; OneConnect intelligent control plane
  • Services: Cloud-based SLA Portal; PinPoint C-OTDR (Optical Time Domain Reflectometer); Managed Network Operations Center (NOC); network health; topology discovery; alarm correlation

Because Ciena recognizes that one size does not serve all, operators can build custom solutions by choosing the building blocks they require for purpose-built networks that address specific market requirements.

Here are some examples of how the various components work:

Ciena's SLA Portal enables you to dramatically improve customer satisfaction and retention by providing transparent visualization of service performance. Customers can self-diagnose network service health and verify SLA performance assurance. In addition, the portal is quick and simple to set up and is a fully managed subscription service, with no need for additional IT investment.

Through Ciena’s innovative approach, you can now offer secure access to a customer-branded portal that delivers performance reporting in a customized dashboard format. The startup costs are low, and the solution is fully scalable to support the largest networks and customer bases. In addition, the SLA Portal can be fully tailored to fit seamlessly into existing service provider portals.

PinPoint C-OTDR provides visibility into submerged plant performance of multiple segments and systems. It also enables remote access to C-OTDRs in various sites, from a centralized NOC/data center.

Ciena’s Managed NOC services act as an extension of the customer’s business, providing the networking skills and experience required to manage their network infrastructure, provision bandwidth growth, and minimize network downtime that impacts critical business processes. 

Utilizing big data analytics to move from reactive to proactive maintenance, Network Health provides operators with the ability to quickly identify and address areas where issues might occur in a network.

Ciena’s Topology Discovery maximizes network utilization by uncovering real network connectivity, stitching circuits, and identifying stranded bandwidth. It reduces costs with migration planning and identifying bandwidth bottlenecks.

Alarm Correlation clusters events and reduces the number of issues to troubleshoot. It also reduces times to troubleshoot by identifying related alarms and targeting them simultaneously.

Terrestrial networks have been moving toward packet-based systems because they offer many benefits, such as statistical multiplexing, over-subscription, and economies of scale. GeoMesh Extreme includes those benefits so submarine network operators can enjoy the same advantages as their terrestrial counterparts. By including packet switching, operators can seamlessly carry packet services from end-users to data centers, and everything in between—whether overland or undersea.

When GeoMesh was introduced just a few years ago, it blurred the lines between submarine and terrestrial networks by viewing the network from the end-to-end service paths. GeoMesh Extreme takes that network architecture to the next level by adding a significant number of new features and technologies built on cloud-based software innovation.

With GeoMesh Extreme in your arsenal, you’ll be able to optimize and monetize assets by designing your network from end-to-end. You’ll keep up with voracious global bandwidth growth, protect terabits of traffic, avoid outages that come from inevitable faults, and protect your revenues and margins by combating ongoing price erosion.
