How Cisco Deployed the World’s Largest Converged Core Gateway


Cisco lately introduced the deployment of its 4G/5G cloud-native converged core gateway in a big, U.S.-based, tier-one community. This new converged gateway serves tens of tens of millions of subscribers (5G SA, NSA, and 4G NSA) together with terra bytes of throughput by way of a extremely optimized networking infrastructure. After we began this journey, we knew we needed to depart from conventional improvement approaches to benefit from the most recent technological developments and ship on the promise of 5G in report time.

Traditionally, introducing new know-how (3G, 4G/ LTE) within the wi-fi telecommunication trade has been a posh and time-consuming course of. It isn’t unusual for the entire course of to take as much as a decade to come back to fruition. Monolithic software program merchandise and complicated multi-vendor environments imply the launch of latest companies is a herculean process.

Standard software program improvement helps 2-3 software program releases a yr and is normally a cumbersome and time-consuming improve course of. In consequence, the general time-to-market for brand spanking new companies may be sluggish. This strategy can be extra error-prone as a result of buyer suggestions is included solely on the finish of the software program supply cycle, resulting in greater churn and a number of software program iterations earlier than it makes it to the manufacturing community. Additionally, buyer groups not often work instantly with engineering groups throughout improvement which can lead to a disconnect between the engineers constructing the code and the client groups which are managing the community.

Cisco’s Worth Proposition

Cisco’s Converged Core gateway addresses these challenges by leveraging cloud-native applied sciences and a CICD pipeline to construct a distributed system with lots of of microservices. Our converged core gateway is constructed on 4 key pillars which are crucial to its success in an operator’s community:

  • Extremely out there and geo-redundant design: The converged core structure is designed to be extremely out there, geo-redundant, and scalable, making certain the community stays operational even within the occasion of an outage or failure. To realize this, we used redundant elements and superior networking methods.
  • Full-stack cloud-native resolution: Our full-stack resolution features a containerized BareMetal platform constructed on Kubernetes, supporting totally cloud-native 5G community features. The mixed platform and utility resolution gives a extra steady and fine-tunable resolution for purchasers.
  • Automation-driven deployment: Leveraging Cisco’s Community Providers Orchestrator (NSO) toolset for automating the deployment and administration of community companies has considerably lowered the effort and time required to deploy and keep the community whereas rising its reliability and efficiency.
  • Simplified real-time monitoring: Platform and 5G functions are monitored in real-time, this permits the community operator to detect anomalies early and avert potential points earlier than they turn out to be customer-impacting.

A Distinctive Strategy

To efficiently deploy this resolution at an enormous scale towards an aggressive timeline, we created closed-loop communication between our engineering groups and the client groups. This strategy enabled tighter collaboration and a product that matched buyer expectations from the very begin.

Bringing engineering and buyer groups nearer – bridging the hole

By making buyer groups an integral a part of the general software program improvement and supply course of, we created a co-development atmosphere supporting sooner iteration of latest options and the power to check them in a managed atmosphere each inside Cisco labs and the client lab earlier than releasing them to manufacturing.

This strategy helped streamline the software program improvement course of enabling frequent software program drops, bettering software program high quality, and accelerating the time to deployment.

The software program improve course of was standardized to observe a rolling improve technique that simplified the general course of and lowered the improve time from a number of hours to beneath one hour.

Bringing engineers into the fold for real-time monitoring

Software program engineers have been empowered with real-time community monitoring, offering visibility into crucial points early so that they might be proactively addressed. Moreover, real-time information on community service stage KPIs (Key Efficiency Indicators), enabled the software program engineers to raised perceive how the software program is used within the area and the affect of any points on the general efficiency of the community.

The consequence? Actual-time monitoring by the engineering workforce accelerated the event cycle and helped to ship high-quality software program to the client.


A strong and progressive resolution, our Converged Core gateway gives allows service suppliers to optimize their networking infrastructure as they undertake new applied sciences equivalent to 5G. And with its extremely out there and geo-redundant design, containerized platform, deployment automation, and monitoring capabilities, Cisco’s Converged Core gateway offers prospects a definite edge in a extremely aggressive trade.
