Dell'Oro: Cloud Deceleration Expected in 2023

Hyperscale data center capex is on track for 28 percent growth 2022, according to a new report from Dell'Oro Group, owever, cloud service providers are expected to enter a digestion cycle in 2023.

“Data center capex has grown double-digits for the fifth consecutive quarter, led by the US hyperscalers’ investments in new data center footprints,” said Baron Fung, Research Director at Dell’Oro Group. “With supply improvements in the recent quarter, vendors were able to reduce backlog significantly in the rest of cloud and enterprise markets. However, we anticipate growth headwinds ahead, as the hyperscalers wind down on their expansion cycle, and enterprises tighten IT capital spending in light of an uncertain business climate,” explained Fung.

Additional highlights from the 3Q 2022 Data Center IT Capex Quarterly Report:

  • China cloud and enterprise data center markets are undergoing deep spending cuts.
  • Upcoming server architectural changes will drive long-term data center investments.
  • Data center capex growth is projected to grow single digits in 2023.

Zayo highlightes a series of expansions to its independent fiber network infrastructure, including continued growth in its long-haul capacity with three new and overbuilt dark fiber routes, 18 new 400 Gbps enabled routes, and a newly completed Transpacific subsea route connecting the U.S. and Tokyo. This series of expansions from Zayo marks the latest in the company’s $250 million investment into its global infrastructure this year. 

Zayo’s two new dark fiber routes include:

  • Cleveland to Columbus: This newly completed route is more direct than other available routes and provides new diversity from existing routes, giving Zayo customers an alternative routing option into Columbus, a growing data center and webscale market.
  • St. Louis to Indianapolis: This route provides the lowest latency and most direct path compared to other providers in the market, and gives Zayo customers an alternative route option to avoid Chicago when connecting East to West markets. The route is scheduled for completion by the end of 2022.

In addition to the new dark fiber routes, Zayo has overbuilt the following route with new fiber capacity:

  • Las Vegas to Phoenix: This low latency route will provide Zayo customers with ample fiber capacity, which is scarce along this route. In 2023, Zayo is set to enable this route with 400G capabilities using the overbuilt fiber.

New 400G routes include:

  • Atlanta to Orlando
  • Chicago to Columbus (Direct)
  • Cleveland to Ashburn
  • Columbus to Ashburn (Direct)
  • Dallas to Houston
  • Dallas to San Antonio
  • Denver to Dallas
  • Ft. Wayne to Chicago (via Indianapolis)

Zayo’s newest completed Transpacific subsea route connects Hillsboro, Oregon, to Tokyo utilizing the TGN-P cable marks the third Transpacific route for Zayo, in addition to its existing capabilities on PC-1 and Unity. The route provides a diverse option to PC-1 for a Transpacific cable landing in the U.S. Pacific Northwest and also includes a diverse landing station in Tokyo. The route is available with pre-provisioned and pre-tested 10G Waves circuits and is managed by Zayo’s network operation center (NOC) for enhanced customer service.

“Zayo is committed to supporting the needs of our customers, not only for today, but for the innovations of tomorrow,” said Bill Long, chief product officer at Zayo. “Zayo is one of the only national providers actively pursuing new fiber builds, which have been enabled through our extensive existing infrastructure footprint, expertise within our teams, and the agile business structure Zayo has worked to build over the last 15 years. The continued expansion of our dark fiber and wave routes provides our customers with the customization and scaling ability they need to accelerate their digital transformation journeys.”

End-to-End network slicing with Ericsson, KDDI

Ericsson, Japanese operator KDDI, and Sony carried out a proof-of-concept (POC) showing end-to-end network across two simultaneous slices for the same user equipment and the same end-user service. 

In this PoC, Ericsson's 5G Core equipment and Sony's 5G SA mobile devices applied User Equipment Route Selection Policies (URSP) standards and Priority Scheduling to enable a gaming app to use two different network slices – one for video and one for mobile operation signals. This showed that dedicated network slices can be used for different processes on a mobile device by changing the terminal’s route selection policies in response to a request from 5G core equipment.

Chris Houghton, Senior Vice President and Head of Market Area Northeast Asia, Ericsson, says: “This significant achievement with KDDI, an important customer of ours, and Sony, a key partner, paves the way for all sorts of applications in network slicing. We will continue to support our customers and partners in Japan to monetize their networks by delivering new value and services for end users.”

The PoC showed that in a highly loaded mobile network, Radio Access Network (RAN) Slicing functions such as Quality of Service and Radio Resource Partitioning (RRP) can provide the required service isolation and differentiated priorities to protect the mobile broadband user performance. In addition, end-to-end network slices were deployed by the Service Orchestration, with the profiles for the RAN and 5G core and cell-level radio resources partitioned using RRP

Mr. Toshikazu Yokai, Managing Executive Officer, General Manager of Mobile Network Technical Development Division, KDDI, stated. “KDDI is constantly working on technology validation with the aim to create new use cases and services utilizing 5G standalone. KDDI will continue to develop and verify technologies to create new value.”

Dell'Oro: Campus switch sales hit record high in 3Q 20

Worldwide campus switch sales were up 23 percent year-over-year (Y/Y) in 3Q 2022, the highest growth rate in nearly two decades, surpassing even the rate of recovery after the two prior market downturns in 2008 and 2020, according to Dell'Oro Group. Growth was broad-based across most vendors, including large and small players, but Cisco was the only vendor with meaningful share gain, increasing by nearly five points during the quarter.

“Gradually improving supply situation is helping release aging backlog, which sent port shipments to record levels for the quarter and for the first nine months of the year,” said Sameh Boujelbene, Vice President at Dell’Oro Group. “ Unfortunately, most of the backlog fulfilled during the quarter is from orders placed ahead of the list price increase. Consequently, vendors’ margins continue to be suppressed as cost continues to rise without being passed on to customers. As a point of reference, the cost of some constrained components went up by factors of 100 to 500.

“With such a strong performance for the first nine months of the year, the market is on track to achieve strong double-digit growth in 2022. Although 2022 is coming above expectations, we have not changed our forecast for 2023 and still predict a low-single-digit growth in the market. This growth will be fueled by near-record backlog levels reported by most manufacturers. Nevertheless, as the 2023 year progresses and backlog starts to normalize, macro-economic headwinds may start to suppress market performance,” added Boujelbene.

Additional highlights from the 3Q 2022 Ethernet Switch – Campus Report:

  • As supply remains tight, market share shifts are and will remain subject to wild quarterly variations that may not be necessarily reflective of competitive displacements, but rather the timing of shipments.
  • Huawei retained the leading revenue position in China, for the second consecutive quarter after being displaced by H3C in 1Q 2022.
  • 5/5.0 Gbps ports were up more than 40 percent Y/Y, marking the second consecutive quarter of strong double-digit growth. What was interesting this quarter was that growth was diversified across various vendors, unlike prior quarters when Cisco used to drive more than two-thirds of the shipments in this segment.

Nokia supplies optical backbone for Portugal's research network

Nokia is building a nation-wide optical transport network spanning 3,000km for FCCN, which provides high-speed Internet connectivity and IT services to the Portuguese higher education and research system. 

The agreement includes Nokia’s 1830 Photonic Service Interconnect optical transport and switching solutions, management systems for the dense wavelength division multiplexing (DWDM) network, and design, implementation, and maintenance services.

Nokia submitted the winning bid in an international tender to build a new RCTS optical network as part of the 17 million RCTS100 Project, 13 of which came from the European Regional Development Fund (ERDF).The new DWDM network replaces FCCN’s legacy OADM network with Colorless-Flexgrid (C-F) reconfigurable optical add/drop multiplexers (ROADMs) to enable simple and remote reconfiguration of lightpaths, and increases network capacity by a factor of 10 using 100G/200G wavelengths.
