According to Cisco\u2019s\u00a0Impact of AI on WAN Traffic\u00a0research, tasks performed by AI agents can generate up to\u00a0450% more network traffic\u00a0than traditional user-driven workflows, with approximately\u00a070% of that traffic attributed to AI inference. As organizations embrace AI at scale, inference traffic is rapidly becoming mission\u00a0critical.<\/p>\n<p>This new reality is transforming networking requirements. Infrastructure must move unprecedented volumes of data across campuses, metro networks, data centers, and cloud environments while\u00a0maintaining\u00a0security, reliability, and operational simplicity.<\/p>\n<p>Meeting that challenge requires more than faster links. It requires a platform approach.\u00a0At Cisco,\u00a0we\u2019re\u00a0building a networking platform that brings together silicon, optics, systems,\u00a0and\u00a0software,\u00a0with security fused into\u00a0every\u00a0layer. By engineering these layers to work together, we help customers\u00a0gain greater value from their network investments\u00a0by simplifying operations and accelerating innovation.\u00a0As AI traffic scales across networks, securing that traffic becomes just as important as transporting it.<\/p>\n<h2><strong>Why\u00a0security\u00a0matters\u00a0more in the\u00a0age of AI\u00a0<\/strong><\/h2>\n<p>Historically, network security strategies focused on protecting the perimeter. Today\u2019s AI-driven networks\u00a0operate\u00a0differently.\u00a0AI training clusters move massive datasets between locations. Agentic AI systems continuously exchange information across applications, clouds, and data centers.\u00a0Hyperscalers, service providers,\u00a0and\u00a0enterprises alike are carrying increasingly valuable data across optical infrastructure.<\/p>\n<p>The network itself has become part of the security perimeter.\u00a0This creates two critical requirements:<\/p>\n<p>Protect the data.\u00a0As AI models, datasets, and business intelligence become strategic assets, protecting data in motion against interception and tampering is paramount.<\/p>\n<p>Preserve performance.\u00a0Security cannot become a bottleneck. AI workloads are\u00a0highly sensitive\u00a0to latency, throughput, and network efficiency. Encryption must\u00a0operate\u00a0at line rate and\u00a0near-zero\u00a0latency.<\/p>\n<p>Organizations need both. They cannot afford to compromise one for the other.<\/p>\n<h2><strong>Rethinking\u00a0encryption for\u00a0scale-across\u00a0networks\u00a0<\/strong><\/h2>\n<p>Today\u2019s networks require a flexible, multi-layered approach to encryption that aligns with operational goals, infrastructure investments, and performance requirements. Whether supporting hyperscale AI clusters, service provider transport networks, or enterprise WAN deployments, organizations need encryption solutions that fit their environments.<\/p>\n<p>MACsec (Media Access Control Security) is a network standard from IEEE 802.1AE that protects data moving across local Ethernet links.\u00a0Cisco offers the flexibility to deploy MACsec at different layers as needed by network operators.<\/p>\n<h2><strong>Encryption in\u00a0silicon\u00a0<\/strong><\/h2>\n<p>Embedding MACsec directly into network silicon allows operators to combine advanced routing capabilities with high-performance security.\u00a0Cisco Silicon One\u00a0exemplifies this approach. By integrating encryption capabilities directly into the forwarding architecture, organizations can secure traffic at scale while preserving operational simplicity and performance. Cisco\u2019s Silicon One P200 processor extends this model with integrated MACsec capabilities designed for the next generation of high-capacity routing infrastructure.<\/p>\n<h2><strong>Encryption at the\u00a0physical\u00a0layer\u00a0<\/strong><\/h2>\n<p>PHY-based encryption\u00a0remains\u00a0attractive where minimizing latency is the highest priority. Operating extremely close to the physical transmission layer enables exceptional performance.\u00a0However, dedicated PHY-based implementations may introduce power and design tradeoffs, requiring operators to carefully balance security requirements against system-level efficiency.<\/p>\n<h2><strong>Encryption in\u00a0optical\u00a0transport\u00a0systems\u00a0<\/strong><\/h2>\n<p>Encryption in optical transport systems helps secure data as it moves across metro, regional, and long-haul networks, providing an\u00a0additional\u00a0layer of protection for traffic traversing shared or third-party infrastructure. By securing traffic at the transport layer, organizations can extend consistent security policies across network domains while helping meet compliance, sovereignty, and data protection requirements.\u00a0Transport systems continue to play\u00a0an important role\u00a0in environments requiring network demarcation, regeneration, or multi-vendor interoperability.\u00a0These architectures can provide clear security boundaries across network domains, though they may also add operational complexity, power consumption, and equipment footprint compared to\u00a0pluggable\u00a0alternatives.<\/p>\n<h2><strong>Encryption in the\u00a0pluggable\u00a0<\/strong><\/h2>\n<p>Coherent pluggable optics introduce a compelling alternative.\u00a0By integrating encryption directly into coherent optical modules, operators gain the flexibility to add security exactly where it is needed without replacing existing\u00a0routers\u00a0or switch\u00a0infrastructure. This approach extends the life of deployed platforms, especially for switches or routers that\u00a0don\u2019t\u00a0have integrated MACsec. It\u00a0allows security investments to be introduced incrementally and enables future cryptographic innovations to be deployed through module upgrades.<\/p>\n<p>This flexibility is becoming increasingly important as organizations prepare for a future that may require new cryptographic algorithms and quantum-resistant capabilities.\u00a0To address these evolving requirements, Cisco recently announced\u00a0MACsec capabilities for its 800ZR coherent pluggable, extending secure transport directly into the optical layer.\u00a0By combining high-performance coherent optics with integrated encryption, customers can simultaneously address capacity growth and security requirements without introducing additional devices or operational complexity.<\/p>\n<p>The key advantage\u00a0is\u00a0choice.\u00a0Cisco offers the flexibility to deploy MACsec at different layers as needed by network operators. As AI drives higher traffic volumes and more distributed infrastructure, no single encryption model fits every deployment. Supporting encryption across multiple layers gives organizations the flexibility to balance security, latency, operational simplicity, and investment protection as their networks evolve.<\/p>\n<h2><strong>The Cisco\u00a0full-stack\u00a0advantage:\u00a0trust at\u00a0every\u00a0layer\u00a0<\/strong><\/h2>\n<p>The location of encryption is important.\u00a0Trusting the infrastructure that performs\u00a0the encryption\u00a0is equally critical.<\/p>\n<p>Cisco\u2019s platform advantage extends beyond encryption itself. It encompasses the complete lifecycle of trust, from silicon to software to optics.<\/p>\n<p>At the\u00a0foundation is Cisco\u2019s\u00a0Root of Trust (RoT)\u00a0architecture, which\u00a0establishes\u00a0a hardware-based security anchor across the network.<\/p>\n<p>When encryption is deployed inside a pluggable coherent module, Root of Trust technology verifies firmware integrity through secure boot procedures and ensures device authenticity. This helps prevent unauthorized modifications and protects against counterfeit hardware entering the network.<\/p>\n<p>When encryption\u00a0resides\u00a0within routing platforms and silicon, the Root of Trust extends protection across the operating environment. It\u00a0validates\u00a0system software integrity and helps safeguard the cryptographic policies and keys that secure customer traffic.<\/p>\n<p>The result is a security architecture that protects not only data in transit, but also the infrastructure responsible for securing that data.<\/p>\n<p>This is the advantage of a platform designed with security integrated at every layer, extending protection from the silicon and operating environment to the network infrastructure that powers AI-driven operations.<\/p>\n<h2><strong>Preparing\u00a0networks for the\u00a0future\u00a0<\/strong><\/h2>\n<p>The demands of AI will continue to reshape networking as organizations will need to manage increased traffic volumes, more distributed data, and intensified security requirements.<\/p>\n<p>Cisco is helping customers prepare for that future through a platform that brings together secure silicon, advanced optics, resilient systems, and intelligent software.<\/p>\n<p>The networks powering the AI era must be secure by design, trusted from the silicon to the optical layer, and flexible enough to evolve with the opportunities ahead.<\/p>\n<p>That is the promise of Cisco\u2019s platform advantage.<\/p>\n<p>\u00a0<\/p>\n<p>\u00a0<\/p>\n<hr\/>\n<h2><strong>Join us at ECOC and PONC<\/strong><\/h2>\n<p><b><span data-contrast=\"auto\">ECOC 2026<\/span><\/b><span><br \/><\/span><span data-contrast=\"auto\">September 20 \u2013 24, M\u00e1laga, Spain<\/span><span><br \/><\/span><span><br \/><\/span><span data-contrast=\"auto\">Visit Cisco at\u00a0<\/span><b><span data-contrast=\"auto\">Booth #2008<\/span><\/b><span data-contrast=\"auto\">\u00a0to see our latest\u00a0optical, optics, and routing\u00a0innovations and hear how customers are deploying\u00a0them\u00a0to power\u00a0AI\u00a0networks.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:2,&quot;335559740&quot;:300}\">\u00a0<\/span><\/p>\n<p><b><span data-contrast=\"auto\">Cisco Packet Optical Networking Conference (PONC)<\/span><\/b><span><br \/><\/span><span data-contrast=\"auto\">September 29 \u2013 October 1, Dallas, Texas<\/span><span><br \/><\/span><span><br \/><\/span><span data-contrast=\"auto\">Attend in person or\u00a0virtually to\u00a0explore the latest innovations in AI networking,\u00a0optical systems, routing,\u00a0optics, and secure transport infrastructure.\u00a0Please reach out to your Account Executive for registration information.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:2,&quot;335559740&quot;:300}\">\u00a0<\/span><\/p>\n<p><span data-contrast=\"auto\">We look forward to\u00a0connecting with\u00a0you.<\/span><span data-ccp-props=\"{&quot;134233117&quot;:true,&quot;134233118&quot;:true,&quot;201341983&quot;:2,&quot;335559740&quot;:300}\">\u00a0<\/span><\/p>\n<p>\u00a0<\/p>\n<\/div>\n<p><p><a href=\"https:\/\/dmsretail.com\/online-workshops-list\/\"><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-full wp-image-496\" src=\"https:\/\/dmsretail.com\/RetailNews\/wp-content\/uploads\/2022\/05\/RETAIL-ONLINE-TRAINING-728-X-90.png\" alt=\"Retail Online Training\" width=\"729\" height=\"91\" srcset=\"https:\/\/dmsretail.com\/RetailNews\/wp-content\/uploads\/2022\/05\/RETAIL-ONLINE-TRAINING-728-X-90.png 729w, https:\/\/dmsretail.com\/RetailNews\/wp-content\/uploads\/2022\/05\/RETAIL-ONLINE-TRAINING-728-X-90-300x37.png 300w\" sizes=\"auto, (max-width: 729px) 100vw, 729px\" \/><\/a><\/p><br \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Welcome to the\u00a0agentic\u00a0AI era, where\u00a0AI agents are becoming\u00a0the new\u00a0network power users,\u00a0operating\u00a0at\u00a0machine speed\u00a0rather than human speed.
