KDDI deploys TIP's Distributed Disaggregated Backbone Routers

KDDI started deployment of the Telecom Infra Project's Distributed Disaggregated Backbone Routers (DDBR) as the Internet gateway peering routers.

KDDI estimates that DDBR carrying live internet traffic could reduce power consumption by about 46% and the rack space by about 40% compared to the traditional routers in KDDI production networks.

KDDI cites two key advantages for its DDBR architecture:

1. Optimal Merchant Silicon Selection and Configuration

Traditional routers comprise software, hardware and semiconductor chips chosen by one vendor. On the other hand, this DDBR comprises DriveNets Network Cloud software, hardware (40×100GE line card systems) from Delta Electronics, and merchant silicon (Jericho2) from Broadcom. Only one Jericho inside the hardware box has enough capability to fulfill software/hardware features and scalability in KDDI production networks. As a result, DDBR leads to reduce the power consumption, the equipment capital cost and the rack space.

2. Sharing of Hardware Resource

In a carrier's traditional network architecture, the dedicated routers for core, edge and internet GW are deployed depending on each area. On the other hand, DDBR can utilize the same white box hardware infrastructure for multiple areas such as core, edge and internet GW. As a result, it will enable KDDI to share hardware spare parts in our backbone networks, leading to the reduction of the equipment capital cost.

KDDI completed the DDBR technical requirements document in May 2021 and TIP announced the DDBR compliant vendors in March 2022. In March 2022, KDDI completed a final phase of commercial testing for DDBR.

FCC considers spectrum sharing for 42 GHz band

The FCC opened a proceeding to consider innovative sharing models in 500 megahertz of spectrum in the 42 GHz band. 

As the spectrum between 42-42.5 GHz is largely unused, the FCC proposes exploring an innovative, non-exclusive spectrum access model in this greenfield spectrum, which is ideal for experimentation due to the lack of incumbent licensees.

The FCC proceeding build a record on the benefits and drawbacks of implementing a shared licensing approach in this band.  It will seek comment on three specific shared licensing approaches: 1) a nationwide non-exclusive licensing approach, in which licensees coordinate specific deployment sites with a third-party database; 2) a site-based licensing approach, in which licensees would apply for each deployment site directly with the FCC; and 3) a technology-based sensing approach, in which operators would employ such technologies to avoid harmful interference from one another.

The NPRM proposes licensing the 42 GHz band as five 100 megahertz channels, and seeks comment on other aspects of implementing a shared licensing approach, including coordination mechanisms, first-in-time protections, buildout requirements, technical rules, and potential synergies with the sharing approaches being considered for the Lower 37 GHz (37-37.6 GHz) band.  It also proposes measures to protect radioastronomy services in the adjacent 42.5-43.5 GHz band.

FCC Chairwoman Jessica Rosenworcel states: So much of what is creative in wireless happened here first, on our shores.  And this agency played no small part in making this true.  We were the first to borrow the academic ideas of Ronald Coase and reimagine the distribution of airwaves with auctions.  More than three decades later we have raised $233 billion using this tool—one we need Congress to continue.  We were also the first to take a handful of underused frequencies known as “garbage bands” in the 900 MHz, 2.4 GHz, and 5.8 GHz range and do something radical—give the public access to these airwaves.  It worked because this is the unlicensed spectrum where Wi-Fi was born.  More recently, we blazed a trail for incentive auctions—again, the first to do this in the world.  We also created an innovative structure with a hierarchy of rights in the 3.5 GHz band combined with new systems to support dynamic spectrum access.  

Our goal today is to continue that creative streak.  This time we are going to do it with a millimeter wave band.  When I took over at the Federal Communications Commission, I believed the agency had overinvested in millimeter wave auctions at the expense of moving to market the mid-band spectrum essential for nationwide 5G service.  So we pivoted—fast.  With the help of my colleagues, we quickly launched auctions in the 3.45 GHz band and 2.5 GHz band.  With those successful mid-band efforts in the rear-view mirror, we are now turning back to millimeter wave.  But this time we want to consider something different.  

In the 42 GHz band we have 500 megahertz of greenfield airwaves with no federal or commercial incumbencies.  So we are putting out ideas.  We are exploring non-exclusive access models.  This could entail using a technology-based sensingmechanism to help operators actively detect and avoid one another.  It could involve non-exclusive nationwide licenses that leverage a database to facilitate co-existence.  It could also entail site-based licensing.  To get even more out of this effort we ask if our approaches could be combined with shared-used models in other spectrum bands, like the lower 37 GHz band."

Dell'Oro: Market for cloud security solutions continues growth

The worldwide market for virtual- and software-as-a-service(SaaS)-based network security solutions achieved its twentieth consecutive quarter of sequential revenue growth in 1Q 2023, according to a newsly published report from Dell'Oro Group.

The pace of year-over-year (Y/Y) revenue growth for these solutions was over 20 percent in 1Q 2023, which was over twice as strong as for the traditional network security hardware appliances.  Network security solutions available in a virtual- or SaaS-based form factors span both traditional and newer product segments, such as firewalls, security service edge (SSE), secure web gateway (SWG), and web application firewalls (WAF).

“The shift to a cloud-centric IT architecture created a seismic shift in how enterprises consume network security technology with virtual- and SaaS-based network solutions grabbing the limelight,” said Mauricio Sanchez, Research Director at Dell’Oro Group. “In a world where applications, data, and users are all over the globe, the traditional approach of deploying hardware just doesn’t cut it anymore, and it’s the flexibility and agility of software and cloud-delivered form factors that are the better fit for the modern enterprise,” added Sanchez.

Additional highlights from the 1Q 2023 Network Security Quarterly Report:

  • Zscaler, Palo Alto Networks, and Akamai owned over a third of the network security market consisting of virtual- and SaaS-based solutions.
  • Zscaler was the top vendor in the SSE market, which is entirely SaaS-based (cloud-delivered).
  • Palo Alto Networks cracked into the top three due to its strong performance in the SSE and virtual firewall markets.
  • Akamai was the leading vendor in the SaaS-based WAF market.

Dell'Oro: Ethernet adapter market correction underway

A correction for the Ethernet Controller and Adapter market is underway as server vendors and cloud service providers reduce excess inventories as server demand weakens, according to a new report from Dell'Oro Group. However, the Smart NIC market is poised for double-digit growth in 2023, with broader adoption in the Cloud and Enterprise markets.

“After achieving record growth in 2022, the Ethernet Controller and Adapter market started the year on a soft note with revenues down 8 percent Y/Y in 1Q 2023,” said Baron Fung, Senior Research Director at Dell’Oro Group. “This was not a surprise given that the market for most server components has been in a correction for several quarters, and server demand had fallen sharply during the quarter. This slowdown could persist for several quarters. However, there are growth opportunities in 2023, with increased Smart NIC adoption and shift towards higher server port speeds to support accelerated computing requirements for AI applications,” added Fung.

Additional highlights from the 1Q 2023 Ethernet Adapter and Smart NIC report include:

  • The Ethernet Controller and Adapter market is forecast for 6 percent revenue growth in 2023.
  • 100 Gbps and higher speed ports could account for nearly half the market in 2023.
  • Smart NIC open vendors such as AMD, Intel, and NVIDIA in a position to capture more than 30 percent of the Smart NIC market in 2023.
