“Janus” Initiative Virtualizes Comcast’s Core
Network to Maximize Performance and Continue Delivering Superior
Internet Connectivity Today and Into the Future
Today Comcast unveiled Janus, an initiative that leverages
leading-edge cloud and AI/ML technology to transform the way its
core network will deliver next-generation Internet experiences to
customers today, and into the future. Janus maximizes network
performance and efficiency by virtualizing Comcast’s core network,
unlocking the ability to deliver consistently faster speeds and
even more reliable Internet service so customers can stream live
sports in 4K, stay connected when extreme weather hits, or use
their increasing number of devices to videoconference, VR, game,
surf and do everything else they want to do online.

Janus will transform the way the nation’s largest network,
accessible to more than 63 million locations nationwide, manages
the flow of Internet traffic to and from customers by shifting
management and control of its core routing, switching and transport
network functions to its edge cloud platforms. Traditionally, these
functions have been managed by proprietary hardware systems in
facilities across the country and now they will leverage the latest
innovation in cloud, edge compute, AI/ML, virtualization, and
digital optics.
Comcast is one of the first network operators in the world to
take these critical steps to virtualize and disaggregate the core
of its transport network and position it for the future of data
consumption. The move is designed to further enhance the
flexibility, reliability, and resiliency of its connectivity
offerings for both Xfinity and Comcast Business customers.
“Data usage continues to skyrocket at unprecedented rates,
primarily due to the rapid increase in streaming high-quality live
sports,” said Elad Nafshi, Chief Network Officer, Comcast. “Janus
builds upon years of investment and innovation to maximize our
network performance and will be a gamechanger for our customers,
our business, and the environment.”
Janus eliminates the proprietary bookended hardware components
and embedded software in Comcast’s network that configures and
manages the routing and transport of data to and from customers and
the Internet and replaces them with white box hardware and with
software that can perform those functions seamlessly. It also
incorporates next-generation, AI-powered self-healing functions
based on real-time telemetry and analytics, removing the
opportunity for human error in core network operations. Initial
trials are underway within Comcast’s network hub in Atlanta, with
wide-scale rollout expected in 2025.
The initiative is expected to deliver many benefits to Comcast
and its customers, including:
Speed for the Need
Football, the Olympics, soccer, basketball, baseball, and more
sports are increasingly streamed with each new season, causing data
traffic patterns to fluctuate massively on a daily basis. Janus
allows the network to scale capacity where it is needed seamlessly,
faster, with the lowest possible latency for live-streamed
performances, so customers never miss a beat.
Enhanced Reliability
When extreme weather, accidents, or vandalism cause damage to
the fiber, facilities or components that make up the core of
Comcast’s network, Janus will enable pinpoint visibility into where
the issue has occurred and eliminate the manual work required to
fix it. It automates the process of rerouting data traffic to
redundant network pathways that are not damaged to restore service
to customers faster. It also enables AI and machine learning
operations and performance optimizations, end-to-end, across
Comcast’s entire broadband network.
Cleaner, Greener Internet
Moving to more power-efficient virtualized and disaggregated
compute platforms will help reduce Comcast’s footprint and further
the company’s goal of being carbon-neutral by 2035. It shrinks the
space occupied within network facilities and reduces the amount of
electricity required to power and cool them.
To deploy Janus in the Atlanta region, Comcast is leveraging
Network Cloud software developed by DriveNets, a leader in cloud
network technology, and a “white box” solution provided by
UfiSpace. Comcast is further leveraging a new generation of
disaggregated, pluggable optics from multiple vendors enabling
greater performance and optionality across its core network. This
combination allows Comcast to use the best-in-class vendors for
hardware, software, and optics and for its core network, innovate
faster and reduce its overall costs.
