Building Strong Networks: Resilience vs. Diversity

Building Strong Networks: Resilience vs. Diversity

May 29, 2024

In the complex world of network architecture, resilience and diversity are pivotal in ensuring robust, uninterrupted services. Each concept plays a critical role, and their greatest potential is unlocked when they work together.

Resilience refers to a network’s ability to maintain an acceptable level of service in the face of various faults and challenges. Strategies to enhance resilience include implementing redundancy, which involves the presence of duplicate elements within the network infrastructure. This redundancy ensures continued operation and reliability, even when one component fails.

Diversity in network design means incorporating a variety of routes, vendors, technologies, and access points to prevent single points of failure. It involves using distinct and physically separate paths, technologies, or providers for network connections. This strategy is crucial for mitigating risks that could lead to widespread network failures, enhancing the network’s reliability and resilience against failures, including natural disasters or intentional attacks.

How Resilience and Diversity Complement Each Other

The synergy between resilience and diversity is particularly effective. For example, a network that not only has multiple pathways to reroute traffic (resilience through redundancy) but also uses different technology providers for these pathways (diversity) is far more robust. Such a network is better equipped to remain operational under multiple types of failures. The combination of diversified resilience strategies—where the methods for achieving resilience are themselves diverse—ensures that networks can withstand complex, unpredictable challenges.

Businesses must evaluate their current network structures and identify areas for enhancement to integrate resilience and diversity effectively. Key steps include conducting a thorough risk assessment, developing a plan that incorporates diverse technologies and providers, and regularly testing network resilience to ensure all systems function as expected when disruptions occur.

Resilience and diversity are foundational to strategic network planning. By understanding and deploying both, businesses can create networks that are not only robust and reliable but also prepared to handle the evolving challenges of the digital landscape.

In a world increasingly driven by data and connectivity, the importance of robust digital infrastructure cannot be overstated. This year at International Telecoms Week (ITW) 2024 hosted by Capacity Media, industry leaders and innovators gathered for an insightful Fishbowl Panel to discuss which routes are most influential in expanding subsea connectivity — that’s 99% of all intercontinental internet traffic.

Andy Bax, Senior Partner, Digital Infrastructure – Cambridge Management Consulting (moderator)

Wilfried Dudink, Strategy & Development, Network Service Providers – Digital Realty

Gil Santaliz, CEO – NJFX

Kapil Kumar Jain, VP & Global Head Network – Tata Communications

Noah Drake, President & Managing Director – Telstra

Monica Martinez Quero, Chief Marketing Officer– Telxius

Addressing Challenges and Seizing Opportunities in Subsea Connectivity

Andy kicked off the panel with a vibrant introduction of the participants, emphasizing the comprehensive expertise gathered. “We’ve all been in the business; we’ve been there, done that. We’ve run operations, we’ve built systems, we’ve developed networks,” Andy explained. He underscored the importance of smaller cable systems, posing to the panel, “What role do they play today? What role might they play in the future?”

Monica Martinez Quero, CMO at Telxius, took the lead, articulating the significance of smaller cable systems. “These systems connect less populated areas with less demand, serving as vital links for growing markets,” Monica said. She highlighted the San Juan project, extending from Punta Cana in the Dominican Republic to Puerto Rico and onto the United States, as a pivotal development in bridging high-capacity gaps in the Caribbean.

Monica further described the Junior cable, a 390-kilometer submarine system connecting Rio de Janeiro to Santos, which plays a critical role in routing traffic from Argentina to Virginia Beach in the U.S. “These cables are a part of the bigger topology map in the industry and play a big role due to their strategic positions and capabilities,” she added.

Acknowledging Monica’s insights, Andy reflected on the broader implications. “People often think about small systems as being regional, connecting small populations. But they are a different part of the ecosystem, integral to our global infrastructure.”

Gil Santaliz, CEO of NJFX, brought to light the strategic importance of the Confluence Cable System, a pivotal infrastructure project enhancing connectivity along the East Coast of the United States. “The Confluence Cable is providing an alternate path connecting five key landing stations—Boca, Jacksonville, Myrtle Beach, Virginia Beach, and Wall, New Jersey,” Gil explained. He emphasized the system’s role in offering failover capabilities and addressing the aging infrastructure challenges traditionally handled by highways and railroads. “By avoiding the congested right-of-way issues, this system not only supports inter-country but also intra-country traffic, enhancing the technological landscape significantly,” he added.

Noah Drake, President & Managing Director at Telstra, then shifted the focus towards regional connectivity and its impact on underserved populations. “The regional systems play a critical role, especially in the South Pacific, where we bridge the digital divide through a mix of subsea, wireless, and satellite technologies,” Noah noted. Reflecting on Telstra’s acquisition of Digital South Pacific, he highlighted collaborative efforts with governments to make these projects viable, emphasizing the synergy between commercial interests and social responsibilities.

Kapil Kumar Jain, VP & Global Head Network at Tata Communications, expanded on the discussion by linking the functionality of small cable systems to broader network resilience. “On both the East and West Coasts of the U.S., these smaller systems provide crucial alternate connectivity,” Kapil pointed out. He detailed how, during simultaneous disruptions of major routes, smaller systems facilitate a mesh ecosystem that maintains network integrity. “These cables are integral to our industry’s future, potentially increasing to represent 30-40% of our ecosystem within the next five years as we aim to connect digitally divided regions,” he projected.

As the panel discussion revealed, small submarine cable systems are more than mere supplements to their larger counterparts; they are vital components that ensure robust, resilient, and inclusive global connectivity. This holistic approach not only addresses immediate logistical challenges but also paves the way for a more interconnected and equitable future.

Wilfried Dudink, Strategy & Development, Network Service Providers at Digital Realty, reflecting on the evolving landscape of connectivity hubs in the Mediterranean, emphasized the emergence of new key locations beyond the traditional hubs like Marseille. “Cities like Barcelona, Genoa, Rome, Crete, Athens, and Tel Aviv are becoming significant connectivity hubs, aided by both terrestrial and innovative subsea cable technologies,” he stated. This diversification is seen as a vital strategy for enhancing regional connectivity resilience.

Andy Bax then broadened the discussion to address the challenges facing the industry, including the shortages in cable ships and manufacturing capabilities. “We’re witnessing a surge in demand for both large-scale and small, regional interconnector cables that offer diversity,” Andy noted. He highlighted ongoing issues such as the shortage of cable ships and the slow pace of scaling up manufacturing post-COVID, which are compounded by the need for dual-purpose ships that can both install and repair cables.

Moreover, there’s a push towards sustainability, demanding that end-to-end cable delivery aligns with eco-friendly practices.” He shed light on the aging fleet of cable ships, with many nearing the end of their service life, underscoring the need for investment in new, sustainable technologies for future developments.

The conversation then shifted towards the impact of geopolitics on the subsea cable industry, a topic further explored by Noah Drake and Gil Santaliz. Noah discussed the strategic delays and challenges posed by permitting processes and geopolitical tensions. “The industry is not just about managing physical resources but also navigating regulatory and political landscapes,” Noah explained.

Gil provided a deeper perspective on how geopolitical tensions are fostering innovation within the industry. “The demand for additional resilience has led to the development of Layer 1 SDN platforms, enabling dynamic switching between subsea cables, thus enhancing the monetization of these assets,” Gil detailed.

Wilfried added that geopolitical shifts are prompting the exploration of new routes, “The current geopolitical climate is pushing the industry to develop alternative routes, enhancing global connectivity diversity.” This includes potentially transformative routes from APAC directly to South Africa and across the Arctic.

Andy reflected on the broader implications of these challenges. “Addressing these issues isn’t just about overcoming technical obstacles but also involves enhancing cooperation between governments and private stakeholders to ensure the deployment of sustainable, resilient infrastructure.”


Adapting to the Evolving Demands of Subsea Cable Infrastructure

Kapil elaborated on the challenges faced by the industry due to recent cable damages and the complexities involved in repair processes. Highlighting the extended downtime, Kapil expressed concern over the industry’s responsiveness to unforeseen incidents, “It’s been two and a half months since the cable cuts, and without permits, we can’t even begin repairs. This situation forces us to rethink traditional routing and introduces substantial challenges but also opens opportunities for innovative solutions.”

The panel also discussed the broader implications of these delays, emphasizing the need for more robust infrastructure and faster response strategies to maintain global connectivity. Andy added perspective on the role of hyperscalers and traditional carriers in building redundancy into their networks. “Hyperscalers are pushing the boundaries, not just focusing on route diversity but also on path and system diversity, which is increasingly important as we aim to ensure resilience in our global networks,” Andy noted.

Wilfried touched upon the development of new connectivity hubs in the Mediterranean, expanding the geographic diversity and resilience of the network infrastructure. “The emergence of new hubs in locations like Barcelona and Tel Aviv represents a strategic evolution, offering alternative routes that enhance the overall robustness of our connectivity solutions,” Wilfried observed.

The conversation shifted to technological advancements that could mitigate some of these challenges. Kapil adding that the deployment of Layer 1 SDN might revolutionize how traffic is managed across these networks. “With SDN technology, we can automate the rerouting process, which currently relies heavily on manual intervention. This could significantly enhance our operational efficiency and reduce downtime during outages,” he proposed.

Andy directed the panel’s attention towards future developments in fiber technology and system capacity. “As we build larger cables with higher fiber counts, we need to consider the long-term implications of these developments on our networks and the global connectivity landscape. How do we manage the increased capacity, and what does it mean for the overall durability of our infrastructure?” Andy questioned.

The panelists discussed the potential for multicore fiber technologies to double the capacity of existing systems without adding more fiber pairs, a critical consideration as the industry seeks to expand capacity while managing the complexities of repair and maintenance.

The panelists delved deeper into the technical, operational, and geopolitical challenges facing the subsea cable industry, exploring strategies to navigate these complexities while fostering innovation and resilience in global connectivity.

The Future of Transatlantic and Global Subsea Networks

Kapil highlighted the ongoing and future challenges in the transatlantic routes, noting the proliferation of new, high-capacity cables. “As we look to the next three to four years, we may see multiple cables with 16 to 25 fiber pairs becoming available in the Transatlantic. However, integrating these cables to create a resilient network remains a puzzle, particularly in Europe,” Kapil reflected. He emphasized the need for innovative solutions to interconnect these diverse routes to ensure robust and redundant network architectures.

Andy responded to Kapil’s insights, focusing on the necessity for direct fiber restoration over mere capacity routing. “What Confluence is aiming to do on the East Coast of the U.S. needs to be mirrored along the entire coast of Europe to ensure seamless fiber restoration,” Andy added, underscoring the importance of comprehensive connectivity solutions that can adapt to unexpected disruptions.

Wilfried shared a specific example from Crete, where multiple cable landing stations are being connected to a central facility to facilitate switching between cables, enhancing network flexibility and resilience. “The project in Crete reflects a broader necessity for integrated infrastructure that can support the dynamic needs of the subsea community,” Wilfried noted.

The panel then opened the floor to questions from the audience, leading to a lively discussion about the investment challenges and educational gaps surrounding subsea cable systems. Andy tackled the overarching challenges facing the subsea community, particularly the need to elevate the industry’s profile to attract investment and governmental support.

Gil addressed the logistical and environmental challenges of deploying subsea cables, highlighting the delicate balance between development and local regulations. “The pushback from local communities and the high costs imposed by municipalities can significantly complicate development efforts,” Gil explained.

The session concluded with a consensus on the critical role of education and collaboration in overcoming the challenges faced by the subsea cable industry. The panelists underscored the importance of raising awareness about the strategic value of subsea cables and fostering partnerships to support sustainable and resilient infrastructure development.

Red Sea conflict

Red Sea Conflict Threatens Key Internet Cables – WSJ

Red Sea Conflict Threatens Key Internet Cables

Maritime attacks complicate repairs on underwater cables that carry the world’s web traffic

Article by Drew Fitzgerald

Full Story here:  Wall Street Journal
March 3, 2024

Red Sea conflict

Conflict in the Middle East is drawing fresh attention to one of the internet’s deepest vulnerabilities: the Red Sea.

Most internet traffic between Europe and East Asia runs through undersea cables that funnel into the narrow strait at the southern end of the Red Sea. That chokepoint has long posed risks for telecom infrastructure because of its busy ship traffic, which raises the likelihood of an accidental anchor drop striking a cable. Attacks by Iran-backed Houthis in Yemen have made the area more dangerous.

The latest warning sign came Feb. 24, when three submarine internet cables running through the region suddenly dropped service in some of their markets. The cuts weren’t enough to disconnect any country but instantly worsened web service in India, Pakistan and parts of East Africa, said Doug Madory, director of internet analysis at network research firm Kentik.

It wasn’t immediately clear what caused the cutoffs. Some telecom experts pointed to the cargo ship Rubymar, which was abandoned by its crew after it came under Houthi attack on Feb. 18. The disabled ship had been drifting in the area for more than a week even after it dropped its anchor. It later sank.

Yemen’s Houthi-backed telecom ministry in San’a issued a statement denying responsibility for the submarine cable failures and repeating the government is “keen to keep all submarine telecom cables…away from any possible risks.” The ministry didn’t comment on the Rubymar attack.

Mauritius-based cable owner Seacom, which owns one of the damaged lines, said fixing it will demand “a fair amount of logistics coordination.” Its head of marketing, Claudia Ferro, said repairs should start early in the second quarter, though complications from permitting, regional unrest and weather conditions could move that timeline. 

“Our team thinks it is plausible that it could have been affected by anchor damage, but this has not been confirmed yet,” Ferro said. 

Cable ships’ lumbering speed makes draping new lines near contested waters a dangerous and expensive task. The cost to insure some cable ships near Yemen surged earlier this year to as much as $150,000 a day, according to people familiar with the matter.

Yemen’s nearly decadelong civil war further complicates matters. Houthi rebels control much of the western portion of the country along the Red Sea, while the country’s internationally recognized government holds the east. Companies building cables in the region have sought licenses from regulators on both sides of the conflict to avoid antagonizing either authority, other people familiar with the matter say.

The mounting cost of doing business also threatens tech giants’ efforts to expand the internet. The Google-backed Blue Raman system and Facebook’s 2Africa cable both pass through the region and remain under construction. Two more telecom company-backed projects also are scheduled to build lines through the Red Sea.

Most of the internet’s intercontinental data traffic moves by sea, according to network research firm TeleGeography. Submarine cables can be simpler and less expensive to build than overland routes, but going underwater comes with its own risks. Cable operators report about 150 service faults a year mostly caused by accidental damage from fishing and anchor dragging, according to the International Cable Protection Committee, a U.K.-based industry group.

“Having alternative paths around congested areas such as the Red Sea has always been important, though perhaps magnified in times of conflict,” ICPC general manager Ryan Wopschall said.

Several internet companies have considered ways to diversify their connections between Europe, Africa and Asia. Routes across Saudi Arabia, for instance, could skirt the waters around Yemen altogether. But many national regulators charge high fees or impose other hurdles that make sticking to tried-and-true routes more attractive. 

“The industry, as with any industry, reacts to the conditions set upon it, and routing in Yemen waters is a result of this,” Wopschall said.
