Cisco presents Silicon One engine of "Internet for the Future"

by James E. Carroll

Cisco unveiled its next generation architecture - its foundation for building a new Internet, by combining silicon, optics, and software. At its "Internet for the Future" event in San Francisco, the company also unveiled new carrier-class routers and discussed an expanded sales strategy that will allow hyperscale web companies and other customers to purchase silicon and optical components directly.

Cisco Silicon One is the new unified, programmable silicon architecture that will be the foundation of Cisco’s routing portfolio going forward, including fixed and modular platforms.  It offers programmability, buffering, power efficiency, scale, and feature flexibility.


The first Cisco Silicon One device - dubbed Q100 - surpasses the 10 Tbps routing performance, although in the near term the company expects to deliver up to 25 Tbps. Q100 actually began sampling 2 years ago and is now shipping. It offers global route scale, deep buffering, and P4 programmability with switching efficiency. It delivers 2x bandwidth and 3x packets-per-second over current routing silicon.

The new Cisco 8000 series carrier-class router is the first platform built with Cisco Silicon One, specifically the Q100. Key features include:
  • Optimized for 400 Gbps and beyond, starting at 10.8 Tbps in just a single rack unit
  • Powered by the new, cloud-enhanced Cisco IOS XR7 networking operating system software,
  • designed to simplify operations and lower operational costs
  • Offers enhanced cybersecurity with integrated trust technology for real-time insights into the trustworthiness of critical infrastructure
  • Service providers gain more bandwidth scale and programmability to deliver Tbps capacity
Saudi Arabia's STC will be the first carrier to deploy the Cisco 8000 series. Comcast and NTT Communications are also testing the platform.

The new Cisco IOS XRT promises:
  • 50% less memory footprint
  • 50% faster boot time
  • 40% smaller image sizes
  • 40% faster download
  • Root-of-trust in the hardware and a cloud-based method for verifying trust in the NOS
Silicon + Optics

Over the past few years, Cisco has been investing in silicon photonics, including its acquisitions of CoreOptics, LightWire and Luxtera.  Its acquisition of Acacia is pending -- all of which reflect the company's desire to improve the availability, capacity, density and power-efficiency, especially at 400G and above.  The strategy has 3 major themes:

  • Optical  innovations will drive architectural transitions, including coherent pluggables and co-packaging.
  • Different optical consumption model, including fully integrated systems, pluggables, and components
  • Cisco Optics on non-Cisco hosts.

In terms of the new sales model, Cisco CEO Chuck Robbins said the key idea is to provide greater flexibility in how customers consume the technology. Cisco cited Google and Facebook as partners who are interested in disaggregated solutions.

Microsoft is testing the use of its SoNIC technology in conjunction with the Cisco 8000 platform.

“Innovation requires focused investment, the right team and a culture that values imagination," said Chuck Robbins, chairman and CEO of Cisco. "We are dedicated to transforming the industry to build a new internet for the 5G era. Our latest solutions in silicon, optics and software represent the continued innovation we're driving that helps our customers stay ahead of the curve and create new, groundbreaking experiences for their customers and end users for decades to come.”

FCC kicks off mmWave spectrum auction

The FCC commenced the next of its 5G auctions, with bidding on spectrum in the upper 37 GHz, 39 GHz, and 47 GHz bands (Auction 103).  The FCC is making 3,400 MHz of millimeter-wave spectrum available through this auction. 

Auction 103 will offer 14,144 Upper Microwave Flexible Use Service licenses in the Upper 37 GHz, 39 GHz, and 47 GHz bands, and the licenses will be based on Partial Economic Areas (PEAs). Category M/N consists of blocks in 37.6 – 40 GHz, including 10 blocks (Blocks M1–M10) in the Upper 37 GHz band and 14 blocks (Blocks N1–N14) in the 39 GHz band; and Category P consists of 10 blocks (Blocks P1–P10) in 47.2 – 48.2 GHz, the 47 GHz band.

Current auctions are posted here: https://www.fcc.gov/auction/103/round-results

“Today’s spectrum auction shows that America is continuing to lead the world in 5G, the next generation of wireless connectivity.  These airwaves will be critical in deploying 5G services and applications.  Auctioning the 39 GHz and upper 37 GHz bands together presents a critical opportunity for 5G deployment as it represents the largest amount of contiguous spectrum available in the millimeter-wave bands," stated FCC Chairman Ajit Pai.

“Notably, we’re setting up the Upper 37 GHz, 39 GHz, and 47 GHz auction to be our second-ever incentive auction.  This one will be different from the broadcast incentive auction that Congress authorized years ago, but it’ll have the same worthy goal: clearing or repacking existing licensees to make spectrum as useful as possible, boosting competition and benefiting consumers.

“Pushing more spectrum into the commercial marketplace is a key component of our 5G FAST plan to advance American leadership in the next generation of wireless connectivity.  Earlier this year, we concluded our first-ever high-band 5G auctions of the 28 GHz and 24 GHz bands. Next year, we look forward to initiating two mid-band spectrum auctions—the 3.5 GHz auction on June 25, 2020, and an auction in the 3.7-4.2 GHz band in the latter part of 2020.  These and other steps will help us stay ahead of the spectrum curve and allow wireless innovation to thrive on our shores.”

NTT develops Direct Spectrum Division Transmission for satellites

NTT has developed a technique called Direct Spectrum Division Transmission (DSDT) that divides the spectrum of the satellite communications signals into multiple sub-spectra, then makes communications after allocating them to the unused frequency slots of the operating band of the transponder in space, and finally recombines the divided sub-spectra into a single carrier signal.

NTT said it has verified this technique in satellite experiments.

The idea is to attach a “DSDT adapter” to an existing satellite modem. This divides and recombines the spectrum of the signal so that unused frequency resources scattered throughout the operating band of the transponder can be used without affecting existing signals of other users that share the same transponder. In addition, this technique enhances communication security by dividing the signal into multiple sub-spectra in the transmitter and combining the multiple sub-spectra back into the original signal in the receiver.

Intel unveils cryogenic control chip for quantum systems

Intel Labs unveiled a cryogenic control chip — code-named “Horse Ridge” — for quantum computing systems. Horse Ridge is a mixed-signal SoC that brings the qubit controls into the quantum refrigerator — as close as possible to the qubits themselves. It effectively reduces the complexity of quantum control engineering from hundreds of cables running into and out of a refrigerator to a single, unified package operating near the quantum device.

Intel said the Horse Ridge design radically simplifies the control electronics required to operate a quantum system. It replaces bulky instruments with a highly-integrated system-on-chip (SoC) that will simplify system design and allow for sophisticated signal processing techniques to accelerate set-up time, improve qubit performance and enable the system to efficiently scale to larger qubit counts. Designed to act as a radio frequency (RF) processor to control the qubits operating in the refrigerator, Horse Ridge is programmed with instructions that correspond to basic qubit operations. It translates those instructions into electromagnetic microwave pulses that can manipulate the state of the qubits.

The Horse Ridge chip, which was developed with TU Delft and TNO (Netherlands Organization for Applied Scientific Research), will enable control of multiple quantum bits (qubits) and set a clear path toward scaling larger quantum systems. Horse Ridge is fabricated using Intel’s 22nm FinFET technology.

“While there has been a lot of emphasis on the qubits themselves, the ability to control many qubits at the same time had been a challenge for the industry. Intel recognized that quantum controls were an essential piece of the puzzle we needed to solve in order to develop a large-scale commercial quantum system. That’s why we are investing in quantum error correction and controls. With Horse Ridge, Intel has developed a scalable control system that will allow us to significantly speed up testing and realize the potential of quantum computing,” states Jim Clarke, Intel’s director of Quantum Hardware.

Apstra accelerates NOS upgrades in multi-vendor networks

Apstra has updated its flagship AOS with the ability to automate and validate Network Operating System upgrades across an entire IP fabric. The new feature, which supports multiple vendors, ensures compliance and reduction in maintenance time from weeks or months to hours or days.

Apstra said it leverages a sophisticated, extensive automated testing platform that verifies the quality of the Apstra AOS software at scale, and models the different services and payloads. The company runs fifteen million unit tests per day, covering 600+ topologies, 100+ physical devices with a variety of hardware vendors, models, and chipsets (Arista, Cisco, Juniper, Dell, Edgecore, Mellanox, Quanta, Celestica, etc) as well as virtual appliances (vEOS, NXOSv, Cumulus, OPX, Ubuntu/CentOS). Any device in the data center can be connected to any other device (physical or virtual) through the use of a reservation system and an automated programmable L1/2 patch panel, which allows Apstra to replicate and test any customer topology in its own infrastructure prior to deployment.

As an example, Apstra said a major financial services company had a single engineer working on OS upgrades, taking upwards of eight months to upgrade 174 switches. The same tasks could have been completed with AOS Maintenance Mode and Device OS Upgrade in approximately 87 hours.

GlobalConnect tests 400G coherent transmission with metro

GlobalConnect, which owns a 42,000 km fiber network and 18,000 sqm high-security data center space in Northern Europe, competed a field trial demonstrating 400 Gbps coherent transmission over a 50 gigahertz (GHz) fixed grid metro transport network concurrently with pre-existing 10G channels.

The trial was conducted over a live GlobalConnect optical link in the Oslo metropolitan area using the Infinera Groove G30 Compact Modular Platform. The trial demonstrated seamless interoperability with deployed metro transport infrastructure. The error-free testing included multiple 300G and 400G alien wavelength transmission use cases over a live metro network link originally designed for and currently running 10G wavelengths using on-off keying (OOK) modulation technology.

The companies said the field trial showcased the ability to boost the capacity of a 10G-engineered OOK-based network by going from 10G to 400G per wavelength, thus increasing the fiber capacity to 32 terabits on an existing 50 GHz fixed grid metro network.

“With the explosive growth in data traffic and acceleration of digital transformation, optical network flexibility and scalability remain critical to our ability to be responsive to our customers’ evolving communications needs,” said Anders Kuhn Saaby, CTO, GlobalConnect. “We remain committed to advancing our fiber infrastructure with cutting-edge technologies to keep pace with growing capacity demands and allow us to expand our addressable market.”

The Infinera Groove G30 is an open, disaggregated networking solution designed to be compatible with third-party optical line systems and diverse network environments, including conventional 10G-engineered non-coherent metro networks designed with OOK, a legacy transport technology that poses limitations for upgrading to higher-capacity wavelengths.
