How Cisco Deployed the World’s Largest Converged Core Gateway

Cisco not too long ago 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 hundreds of thousands 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 growth approaches to benefit from the newest technological developments and ship on the promise of 5G in document time.

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

Standard software program growth helps 2-3 software program releases a 12 months and is normally a cumbersome and time-consuming improve course of. In consequence, the general time-to-market for brand new companies may be sluggish. This method can be extra error-prone as a result of buyer suggestions is integrated 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 hardly ever work immediately with engineering groups throughout growth which may end up in a disconnect between the engineers constructing the code and the shopper groups which might be 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 a whole bunch of microservices. Our converged core gateway is constructed on 4 key pillars which might be vital to its success in an operator’s community:

  • Extremely accessible and geo-redundant design: The converged core structure is designed to be extremely accessible, 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 parts and superior networking methods.
  • Full-stack cloud-native resolution: Our full-stack resolution features a containerized BareMetal platform constructed on Kubernetes, supporting absolutely cloud-native 5G community capabilities. The mixed platform and software resolution supplies a extra secure and fine-tunable resolution for patrons.
  • Automation-driven deployment: Leveraging Cisco’s Community Providers Orchestrator (NSO) toolset for automating the deployment and administration of community companies has considerably diminished the effort and time required to deploy and preserve the community whereas growing its reliability and efficiency.
  • Simplified real-time monitoring: Platform and 5G functions are monitored in real-time, this enables the community operator to detect anomalies early and avert potential points earlier than they develop into customer-impacting.

A Distinctive Method

To efficiently deploy this resolution at a large scale towards an aggressive timeline, we created closed-loop communication between our engineering groups and the shopper groups. This method 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 growth and supply course of, we created a co-development atmosphere supporting quicker iteration of latest options and the power to check them in a managed atmosphere each inside Cisco labs and the shopper lab earlier than releasing them to manufacturing.

This method helped streamline the software program growth 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 diminished 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 vital points early in order that they could possibly 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 impression of any points on the general efficiency of the community.

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


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