Continuous inference, agent-to-agent communication, and real-time data pipelines are generating unpredictable, always-on traffic that legacy architectures were never built to support. As AI moves from pilot project to operational backbone, the network is emerging as a critical control layer that determines performance, reliability, and cost.
The shift is forcing organizations to question assumptions that have held for decades. Legacy systems were static and rigid, and lacked the ability to manage network demand efficiently or dynamically, while AI-ready networks need to adapt in real time. A study by Cisco notes that 80% of executives believe their company’s competitive survival will depend on agentic AI, and consumer usage of AI is already prevalent and accelerating. This is driving a fundamental shift in how traffic is generated, distributed, and experienced, with implications for service providers and enterprises that manage large-scale networks.
This infrastructure gap is a global concern. A recent Bloomberg study, “The Future-Ready Enterprise,” commissioned by Tata Communications, found that while 3 in 4 leaders consider AI a board-level priority, nearly two-thirds (65%) of enterprises continue to operate on transitional or legacy infrastructure. This disconnect between ambition and reality is a primary obstacle to realizing value from AI investments.
The performance bar has also moved by an order of magnitude. Traditional business applications could tolerate 100 to 500 milliseconds of latency, while mission-critical AI workloads now require latency below 10 milliseconds.
“This isn’t just an incremental improvement,” says Kapil, Vice President, Global Network Services at Tata Communications. “It’s a completely different performance paradigm that breaks traditional network design assumptions, where such extreme low latency was never a primary consideration.”
How network performance affects AI reliability and cost
That gap between what legacy infrastructure can deliver and what AI demands turns network performance into a direct driver of AI reliability and cost. Treating the network as a best-effort transport layer introduces risk that many organizations only discover once a deployment underperforms in production. A model built for real-time fraud detection or supply chain optimization becomes worthless the moment network congestion delays the data it depends on, and Kapil notes that every millisecond of that delay can carry a direct financial or operational cost.
“Relying on a ‘best-effort’ network turns multi-million-dollar AI stack investments into a high-stakes gamble, where performance is left to chance,” Kapil says.
He adds that businesses often underestimate the complexity of using the public internet as a global enterprise network. Performance may look acceptable within a single country, but once data starts crossing borders or connecting to international cloud platforms, the lack of end-to-end control becomes an operational barrier.
Distributed AI across cloud, edge, and enterprise increases complexity
Complexity compounds as AI components spread across cloud, edge, and enterprise environments. Organizations often focus on compute power and data infrastructure while overlooking the network fabric that connects them. That blind spot often surfaces as a performance bottleneck created by high-frequency east-west traffic moving between GPUs.
Distribution also widens the surface enterprises have to defend. Applications, users, and partner ecosystems are now spread across cloud, SaaS, edge, and device environments, and Kapil notes that AI-driven malicious bots account for roughly 37 percent of online traffic, making it increasingly difficult to distinguish legitimate users from automated threats. Many enterprises have responded by layering on siloed tools, which has produced fragmentation, inconsistent security, and a lack of unified visibility rather than a coherent defense.
“SASE helps mitigate these risks by converging networking and security into a unified, cloud-delivered architecture,” Kapil says. “This convergence is enabling consistent policy enforcement across cloud, on-premises, and edge environments, while supplying the scalability and proximity needed to secure real-time AI-driven interactions.”
The network must evolve from passive transport to an intelligent layer
Closing that gap requires organizations to gain far greater visibility into how AI traffic moves across distributed environments and the ability to direct workloads accordingly. Kapil says that demands a different approach to network management.
“Leaders must realize that the network is no longer passive ‘plumbing.’ It must be managed as an active, intelligent platform foundational to the entire AI stack,” he says. “That platform requires real-time observability into how and where AI traffic flows, paired with the control to orchestrate workloads across the most efficient and secure path available.”
It’s the difference between merely connecting systems and unlocking new capability, for instance a seamless shopping experience during a peak sales period or a global sports broadcast streamed without buffering.
This intelligence also changes how infrastructure teams spend their day. The network itself is now software-defined and API-driven rather than fixed by hardware configuration, which Kapil says shifts infrastructure teams away from reacting to outages and toward designing the systems that prevent them.
“Instead of manually re-routing traffic during an outage, the team must define the rules, policies, and business outcomes for an intelligent fabric,” Kapil says. “The network itself then executes those policies automatically and autonomously.”
Tata Communications is putting this principle into practice with its recently launched IZO Data Centre Dynamic Connectivity. The software-defined platform creates a “self-healing, intelligent network” using deterministic multi-path routing to reroute traffic automatically in seconds during a disruption.
The company says the platform transforms resilience from a reactive process into an autonomous capability, providing the predictable, low-latency performance mission-critical AI applications require while reducing operational costs by up to 30%.
Real-time AI requires predictable, low-latency connectivity
Delivering on that intelligence in practice means giving mission-critical workloads dedicated capacity rather than having them compete for it. Reaching that level of consistency also requires enterprises to define performance far more precisely than they have in the past. It’s the shift from vague goals like “high performance” toward deterministic performance criteria where an organization commits to a guaranteed service level, such as latency for a specific workload not exceeding 10 milliseconds 99.999% of the time, for instance.
That same demand for predictability extends into capacity planning. As AI workloads become larger and more dynamic, networking infrastructure must be able to absorb rapid shifts in demand without sacrificing performance or efficiency.
“Without dynamic scalability, enterprises are forced into a false choice: either risk performance-killing congestion or engage in massive, inefficient overprovisioning of their network ‘just in case.’ This is incredibly expensive and unsustainable,” Kapil says.
Building this foundation for the world’s most demanding AI workloads is already underway. For example, Tata Communications is collaborating with Amazon Web Services (AWS) to build one of India’s largestAI-ready networks. This high-capacity, resilient network will connect major AWS infrastructure locations in Mumbai, Hyderabad, and Chennai, providing the ultra-low latency backbone needed to accelerate generative AI adoption and cloud innovation across the country.
He points to a consumption-based model, where software allows bandwidth and network functions to scale instantly with demand, as the operational alternative, since it lets organizations pay only for what they use while still protecting performance during spikes.
CIOs should treat the network as a strategic investment
CIOs and infrastructure leaders need to reframe the network, not thinking of it as a cost center but as something closer to an insurance policy for an organization’s broader AI investment portfolio. An intelligent network de-risks those investments in three ways:
enabling dynamic scalability that removes the need for overprovisioning
strengthening security and governance through the visibility needed to protect data and models
and providing a flexible, programmable foundation that can absorb future compute demands without a full architectural overhaul.
Getting there does not require enterprises to start from scratch.
Choosing a partner with a proven track record is critical. Tata Communications was recently named a Leader in the Gartner Magic Quadrant for Global WAN Services for the 13th consecutive year, reflecting its completeness of vision and ability to execute. That recognition reflects continued investment in areas such as SASE capabilities for AI-driven security and high-capacity 800G services designed for AI-scale infrastructure.
“We recommend a phased approach that begins with assessing the current state of the network and identifying inefficiencies, then prioritizing upgrades in areas such as AI-ready technologies, seamless data exchange, and advanced security solutions,” Kapil says. “Treating the network as a business enabler rather than overhead gives organizations the scalable, secure, and resilient infrastructure the AI economy will continue to demand.”
