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 thousands and thousands of subscribers (5G SA, NSA, and 4G NSA) together with terra bytes of throughput through a extremely optimized networking infrastructure. After we began this journey, we knew we needed to depart from conventional improvement approaches to make the most of the most recent technological developments and ship on the promise of 5G in document time.

Traditionally, introducing new know-how (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 come back to fruition. Monolithic software program merchandise and sophisticated multi-vendor environments imply the launch of latest providers is a herculean job.

Typical software program improvement helps 2-3 software program releases a 12 months and is often a cumbersome and time-consuming improve course of. Consequently, the general time-to-market for brand spanking new providers will be sluggish. This method will also 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 hardly ever work immediately with engineering groups throughout improvement which can lead to a disconnect between the engineers constructing the code and the client 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 essential 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 attain 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 features. The mixed platform and software resolution offers a extra steady and fine-tunable resolution for patrons.
  • Automation-driven deployment: Leveraging Cisco’s Community Companies Orchestrator (NSO) toolset for automating the deployment and administration of community providers has considerably lowered the effort and time required to deploy and keep the community whereas growing its reliability and efficiency.
  • Simplified real-time monitoring: Platform and 5G purposes are monitored in real-time, this enables the community operator to detect anomalies early and avert potential points earlier than they change into customer-impacting.

A Distinctive Strategy

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

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

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

Bringing engineers into the fold for real-time monitoring

Software program engineers had been empowered with real-time community monitoring, offering visibility into essential points early so 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 higher perceive how the software program is used within the discipline and the influence of any points on the general efficiency of the community.

The outcome? 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 permits service suppliers to optimize their networking infrastructure as they undertake new applied sciences equivalent to 5G. And with its extremely accessible and geo-redundant design, containerized platform, deployment automation, and monitoring capabilities, Cisco’s Converged Core gateway provides clients a definite edge in a extremely aggressive trade.
