Graphiant shakes up routing with its network edge service

Graphiant, a start-up based in San Jose, California, emerged from stealth to unveil a new network edge service that promises to shake up the established framework of VPNs, including MPLS and SDWAN.

The Graphiant Network Edge provides connectivity between the enterprise WAN, hybrid cloud, network edge, customers and partners. The service promises MPLS-like performance (guaranteed delivery, security and privacy) and Internet-class agility. 

All routing is handled by the Graphiant Stateless Core, which leverages a proprietary routing label system to provision protected paths across an underlay network that is managed by Graphiant. From the enterprise customer perspective, traffic remains encrypted from edge to edge, and SLA-grade performance is guaranteed. The company has its network core deployed in key Equinix data centers serving as its PoPs.

Graphiant's idea is to remove the need for network architects to build bespoke networks between every resource, hybrid cloud, edge network, customer and partner. Instead, they simply connect each resource to the Graphiant Stateless Core. 

“Network architects have to provide connectivity for an impossibly complex world,” says Khalid Raza, CEO of Graphiant. “Connecting business resources, hybrid cloud, edge networks and remote workers, is time-consuming, error-prone and full of security challenges.  We’ve delivered a solution that removes this complexity.”

What's next for enterprise connectivity?

Graphiant, a start-up based in Silicon Valley, has just unveiled a new network edge service that promises to shake up the established framework of VPNs, including MPLS and SDWAN.

In this video, we hear from Khalid Raza, founder and CEO of Graphiant, and who is widely regarded as a visionary in routing protocols and large-scale network architectures. Raza previously was founder & CTO of Viptela, an SDWAN pioneer that was eventually acquired by Cisco for $610 million in 2017.

Comcast to offer symmetrical multi-gig speeds in 2023

Comcast  has begun a nationwide rollout of multi-gig Internet speeds with the goal of reaching more than 50 million homes and businesses before the end of 2025.

As part of this initiative, Comcast is accelerating the transformation of its network to a virtualized cloud-based architecture that is fully prepared for 10G and DOCSIS 4.0.

Under this initiative Comcast is:

  • Immediately rolling out download speeds up to 2 Gigs – combined with up to 5x-to-10x faster upload speeds – to millions of homes and businesses; available in 34 cities and towns before the end of 2022; more than 50 million homes and businesses by the end of 2025; and continuing throughout the entire network. Initial rollouts are already underway in Colorado Springs, CO; Augusta, GA; and Panama City Beach, FL, with more launched at a regular cadence through the end of the year
  • For Xfinity customers: extending new multi-gigabit network speeds throughout the home with the multi-gig-capable Wi-Fi 6E Gateway, xFi connected home platform, and xFi Pod Wi-Fi extenders
  • For Comcast Business customers: Delivering ultra-fast Wi-Fi speeds for businesses with a new multi-gig capable gateway
  • Completing the core technical foundation for 10G, which will deliver multi-gig symmetrical speeds over the connections already installed in tens of millions of homes and businesses
  • Finalizing transition to a cloud-based, virtualized network that enables faster speeds, greater reliability for customers, while also implementing a network architectural update that enables greater upload and download capacity
  • Building multi-gig capabilities that can reach everyone connected to Comcast’s network, not just select neighborhoods and customers, just as Comcast has done with previous network improvements
  • Improving energy efficiency, helping Comcast become carbon neutral by 2035

“We’re making our network even smarter and faster, which allows us to quickly deliver true multi-gig Wi-Fi to tens of millions of businesses and residential consumers at an unprecedented pace,” said Charlie Herrin, President of Technology, Product, Experience at Comcast Cable. “Whatever the application, whatever the future holds, our network and world-class, whole-home Wi-Fi experience will be there and ready to power all of our customers’ connected experiences.”

Comcast demos 10G technologies

Comcast reached download speeds faster than 8 Gbps and upload speeds faster than 5 Gbps during a 10G event at CableLabs headquarters.For the demo, Comcast connected a 10G-enabled Virtualized Cable Modem Termination System (vCMTS) linked by more than 80 kilometers of fiber to the demonstration site. The fiber terminated into a production switch, which connected to what is believed to be the world’s first fully functional 10G-enabled Full Duplex DOCSIS...

Comcast tests Lumenisity's hollowcore fiber

Comcast confirmed its first deployment of advanced hollowcore fiber optics.Comcast connected two locations in Philadelphia, which enables network engineers to continue to test and observe the performance and physical compatibility of hollowcore fiber in a real-world deployment. Comcast successfully tested bidirectional transmission (upstream and downstream traffic traveling on a single fiber), used coherent and direct-detect systems (allowing for...

CableLabs cites 10G milestones

CableLabs cited a number of 10G milestones achieved in 2021:CableLabs recently published its first set of specifications for a new device, called the Coherent Termination Device, that enables operators to take advantage of coherent optics technologies in fiber-limited access networks. Typically used for long-haul, metro and submarine networks, coherent optics technologies enable operators to use their existing fiber assets more efficiently when teamed...

Comcast tests 10G modem based on full Duplex DOCSIS 4.0

Comcast achieved a top downlink performace of over 4 Gbps using a prototype 10G modem.  The lab test used a full duplex DOCSIS 4.0 system-on-chip (SoC) from Broadcom.The modem test utilized the DOCSIS 4.0 FDX SoC device, which Comcast demonstrated in April 2021, to pair with two cable modem chips. These were connected over a lab-based hybrid fiber-coaxial network to the vCMTS operating in DOCSIS 4.0 mode. Comcast said this represents the...
