Network-as-a-Service (NaaS) offers a flexible, cost-effective, and efficient way for businesses to manage their networking needs. Here is an overview to guide your selection and use of NaaS.

Network-as-a-Service (NaaS) is much more than an emerging subscription model for corporate networks.

With NaaS, the provider is responsible for buying and managing the routers, switches, load balancers, firewalls, and other security devices that once made up the infrastructure of costly, resource-draining, and limited-flexibility private networks.

What Preceded NaaS?

For decades, the traditional solution for wide-area networks has been private networks whereby enterprises bought, managed, and maintained networking equipment and secured connections serving onsite data centers. That practice was eclipsed by the more flexible and cost-efficient cloud architecture.

Then came Network-as-a-Service (NaaS), an emerging option intended to be provided across a standards-based automated ecosystem to help organizations meet fluctuating data needs and achieve business goals.

Soaring data traffic, driven by the broadening use of 5G, IoT, and video streaming (and the rapid emergence of AI), has given rise to the newer and more flexible WAN approach. Beyond not buying, managing, or maintaining network equipment, bandwidth, and specialized talent, NaaS offers many capabilities and functionality.

How Network as a Service Works

The MEF, an industry association and advocate for NaaS and friends, describes a full-bodied offering as "a new-paradigm solution by combining on-demand connectivity, application assurance, cybersecurity, and multi-cloud-based services delivered across a standards-based automated ecosystem of partners."

Of great importance is the MEF’s development of a much-needed NaaS Industry Blueprint and its work on open APIs. Network-as-a-Service providers need these APIs to automate common functions like order processing, service provisioning, and security. They can make it easier for an enterprise to order and use NaaS services.

With no viable alternatives, governments, enterprises, and operators team to tackle longstanding undersea cable resiliency challenges.

Is network resiliency able to reach beyond five nines and SLAs for enterprises seeking always-on services?

Given recent headlines and discussion in the wake of undersea cable cuts in the Red Sea, the answer is still no for multinationals. The situation is best described as business interruption as usual.

On Saturday, February 24, three different cables were reported to have suffered faults:

These international systems connect far-apart states like South Africa, the United Kingdom, and China. The faults off the coast of Yemen need to be repaired. The work is tough to do in a narrow, heavily traveled shipping lane that doubles as a war zone with a concentration of submarine cables on the sea floor.

Fighting in the Middle East is a concern as enterprises and the telecom industry rely on undersea cables to carry the bulk of their intercontinental traffic.

Since late February, three more faults in the region have been reported, according to TeleGeography, a research firm that builds and maintains massive data sets that are used to monitor, forecast, and map the telecommunications industry. One report has a ship dragging an anchor as the culprit, which the firm claims is the second most frequent cause behind cuts/faults of these business and communications lifelines.

The cause of the undersea cable disruption is still uncertain

Whodunnit? Since then, no open-source evidence has come out to support the claim that Houthis, part of a Yemen civil war, were responsible. "But here's one thing we do know: accidents happen all the time," noted Tim Stronge, Research VP at TeleGeography, in a March 5 advisory. "On average, two cables suffer faults somewhere in the world every week!”

The research firm tracks 574 active and planned submarine cables as of early 2024.

Suspicious activity or not?

Stronge does not believe the three almost simultaneous cable faults are overly suspicious.

“Geological features or permitting issues have occasionally forced installers to lay different cables in close proximity to each other,” he explained. Such a situation increases the danger of a multi-cable fault.

In 2012, multiple cables suffered faults off the coast of Alexandria, Egypt. “Initial speculation blamed saboteurs, but many in the submarine cable industry now believe that a single ship dragging its anchor was the cause.”

Is it time to panic?

Although the Red Sea cables carry 90% of Europe-Asia communications flow through them, operators have built a lot of redundancy into the network. The ability to reroute traffic is increasingly available.

There are fourteen cables already laid on the Red Sea. Even if three are down, eleven remain, wrote Stronge. “Data destined for damaged cables may be rerouted southward around the Cape of Good Hope or eastward through Asia and the United States.”

Tougher times ahead for undersea cable industry

Houthi attacks on ships make life tougher for the undersea cable industry, which could hurt enterprises.

  • Vessels that are sinking or sunken present new underwater hazards to cables and cable ships. The cables typically lie on the ocean floor.
  • Shipping attacks have caused marine insurance rates to spike.
  • Combined, these two may make the installation of new cables in the Red Sea too prohibitive and make repair risky.

Items for governments to act on

Governments are the ones on the hook for the long-term security of subsea cables. The International Cable Protection Committee (ICPC) has created a list of 16 action items.

ICPC membership comprises governmental administrations and commercial companies that own or operate submarine telecommunications or power cables, as well as other companies that have an interest in the submarine cable industry—including most of the world’s major cable system owners and cable ship operators. The group says the primary purpose of the ICPC is to help its members improve the security of undersea cables by providing a forum in which relevant technical, legal, and environmental information can be exchanged. U.S. members include JP Morgan Chase, Wells Fargo, University of Hawaii, U.S. Navy, Johns Hopkins University, AT&T and Ciena.

One priority, which is a work in progress, is changing rules and regulations to open new seabed lanes and landing zones for cables. Having physically diverse zones provides options in locating where cables come ashore.

Flirting with disaster

“Some government regulations (such as environmental protection) may unintentionally herd cables into narrow corridors,” explained Stronge. “As we’ve seen time and time again, a lack of physical diversity invites disaster.”

Seeking alternatives

When it comes to alternatives to undersea cables, the cupboard is bare. Satellite connections are not fast or large enough to carry the traffic load on submarine pipes. 5G is not mature enough to help.

One approach is to install cables over alternative routes. As we reported in December, the SeaMeWe-6 cable project seeks to construct a cable that links Asia, the Middle East, and Europe via a route through India rather than the Red Sea. The article noted that the U.S. “snatched away” control of the project from China due to the importance of having alternative paths to send data.

Industry experts predict a rapid emergence for the latest Wi-Fi version. Streaming and dense device use cases are seen as fits.

With wireless traffic far exceeding wireline data, it seems like a safe bet that the emergence of Wi-Fi 7 will take and hold the attention of enterprises and carriers looking to put the latest Wi-Fi products to work.

Buoyed by the recently launched Wi-Fi 7 Certified product certification program by the Wi-Fi Alliance, approved products will likely be embraced as part of the most compelling segment of the Internet access market this year.

“With the Wi-Fi Alliance recently announcing the opening of certification testing for Wi-Fi 7 products, don’t be surprised to see dozens of Wi-Fi 7 residential routers and broadband CPE models being deployed by operators by the end of this year,” explained Jeff Heynen, VP Broadband Access and Home Networking at Dell’Oro Group, a global market research firm. "Early gateway models, though pricey, have already been introduced to the market and will become much more widely available this spring and then well before the holiday season."

Why the rise of Wi-Fi 7?

Wi-Fi 7 products offer significantly more performance for enterprise users and can support more users in denser environments compared to Wi-Fi 6. It is pitched as a match for streaming applications and is able to handle more users per Access Point (AP), which translates into fewer devices to manage and maintain in deployments.

Wi-Fi 7 is attractive for many reasons. The first is its flexibility. The IEEE standard 802.11be works with several radio frequency bands, including 2.4GHz, 5GHz, and 6GHz. Its speed is another selling point, as it provides links at up to 40,000 M bit/sec. "When using Wi-Fi 7, the quality and resolution of video streaming are improved by 16 spatial streams and Multiple Input Multiple Output (MIMO) technology," according to Mordor Intelligence. Another feature of Wi-Fi 7, Hybrid Automatic Repeat Request (HARQ), enables multiple link adaptation.

Also of importance is that WI-Fi-7 devices are compatible with its most recent predecessor, Wi-Fi 6E.

Operators to Embrace Wi-Fi 7

There is more to Wi-Fi 7’s rapid emergence than simply technical features and advanced capabilities.

“Operators can’t wait to deploy Wi-Fi 7 products to help differentiate themselves in increasingly crowded broadband markets and to eliminate much of the confusion in the market with the coexistence of Wi-Fi 6 and Wi-Fi 6E,” explained Heynen.

While Wi-Fi 6E offers specific benefits over its Wi-Fi 6 predecessor, the latter has been implemented by entertainment and sports venue owners to best service fans in the stands who are increasingly armed with powerful mobile devices equipped with team and concessions apps. Pro sports teams are using Wi-Fi 6 to collect data from fans, which is used to provide each attendee with a more personalized experience.

Higher Performance Wi-Fi 7 Driven by Soaring Traffic

The amount of traffic being carried over Wi-Fi networks globally has roughly quadrupled in four years. In contrast, traffic over wired networks has only grown modestly during that same period, according to the Wi-Fi Alliance.

Early Wi-Fi 7 Products at Mobile World Congress

Last year saw chip, module, and device vendors, including Qualcomm, Broadcom, Intel, MediaTek, and CommScope, roll out products. Now, the Wi-Fi Alliance is forecasting more than 233 million Wi-Fi 7 devices to enter the market in 2024, growing to 2.1 billion devices by 2028.

Keysight Technologies plans to show its Wi-Fi 7 wireless connectivity test platform at the Mobile World Congress 2024 (MWC) in Barcelona later this month.

Wi-Fi 7 Certified Program to Drive Deployment

Just last month, the Wi-Fi Alliance launched the Wi-Fi 7 Certified program, which is designed to approve an interoperable device that provides a certain set of required capabilities. It is unclear if products released before certification will be compliant or adjusted to be compliant. As a resource for operators and business users (and those working from home), the alliance has created a product finder resource on its website where folks can type in a product name and maker to see if it’s certified.

The Bottom Line on Wi-Fi 7

Streaming-friendly features, frequency flexibility, and the bandwidth to address dense device environments portend to fuel the emergence of Wi-Fi 7. The Wi-Fi 7 market was valued at $875 million in the current year and is expected to reach $6.07 billion in the next five years, registering a CAGR of 47.32% over the forecast period, according to Mordor Intelligence.

The Wi-Fi 7 space is worth watching – closely - for enterprises and operators.
