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 through a extremely optimized networking infrastructure. Once we began this journey, we knew we needed to depart from conventional improvement approaches to reap the benefits of the newest technological developments and ship on the promise of 5G in file time.

Traditionally, introducing new know-how (3G, 4G/ LTE) within the wi-fi telecommunication business has been a fancy and time-consuming course of. It’s not 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 recent providers is a herculean activity.

Typical software program improvement helps 2-3 software program releases a 12 months and is normally a cumbersome and time-consuming improve course of. Consequently, the general time-to-market for brand new providers could be sluggish. This strategy 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 not often work instantly with engineering groups throughout improvement which may end up in 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 a whole bunch of microservices. Our converged core gateway is constructed on 4 key pillars which are essential 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, guaranteeing the community stays operational even within the occasion of an outage or failure. To realize this, we used redundant elements and superior networking strategies.
  • Full-stack cloud-native answer: Our full-stack answer features a containerized BareMetal platform constructed on Kubernetes, supporting absolutely cloud-native 5G community capabilities. The mixed platform and utility answer supplies a extra secure and fine-tunable answer for patrons.
  • Automation-driven deployment: Leveraging Cisco’s Community Companies Orchestrator (NSO) toolset for automating the deployment and administration of community providers has considerably diminished the effort and time required to deploy and keep 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 turn into customer-impacting.

A Distinctive Strategy

To efficiently deploy this answer 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 recent 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 comply with a rolling improve technique that simplified the general course of and diminished 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 in order that they may very well be proactively addressed. Moreover, real-time knowledge on community service degree 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 outcome? Actual-time monitoring by the engineering workforce accelerated the event cycle and helped to ship high-quality software program to the client.


A robust and progressive answer, our Converged Core gateway presents permits 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 clients a definite edge in a extremely aggressive business.
