Vimala Veerappan, Senior Director in the Data Center Networking Business Group at Cisco, presented the company’s evolving data center networking strategy, which focuses on solving the challenges of infrastructure fragmentation, escalating operational complexity, and advanced security vulnerabilities brought on by distributed AI workloads. The core of Cisco’s AI networking strategy is threefold: addressing the operating model, infusing security into every infrastructure layer, and driving operations at the speed of machines. Central to this strategy is Cisco Nexus One, a unified architecture that harmonizes silicon, systems, optics, software, and network operating models. This allows enterprises to build, operate, and secure standard fabrics capable of running both AI and non-AI workloads together, while leveraging recent innovations like the liquid-cooled G300 ASIC, 1.6T optics, native Splunk integration within the Nexus Dashboard, and advanced AI job observability from the fabric to the GPU.
Veerappan introduced key highlights from Cisco Live US, starting with the extension of Nexus One capabilities into Kubernetes environments through standard-based networking and Isovalent technology. Because two-thirds of organizations rely on Kubernetes to run modern AI applications, this integration eliminates traditional operational silos between platform and network teams, offering true multi-tenancy, fabric-to-pod visibility, and automated, mobile security policies that follow workloads wherever they migrate. Cisco is tackling the complexities of shared backend AI infrastructures by introducing automated multi-tenancy and micro-segmentation directly into the fabric itself via an Open API framework. This enables seamless onboarding through preferred AI infrastructure orchestrators and job schedulers, embedding tenant and job IDs into the VXLAN headers to allow precise, job-level isolation and fast root-cause analysis, a capability highly valued by NeoCloud and heavily regulated enterprise customers.
The presentation also emphasized Cisco’s commitment to fabric security and future-proofing operations in an AI-driven threat landscape. To eliminate the scale and physical limitations of centralized firewalls hairpinning distributed AI traffic, Cisco showcased its Nexus smart switches, which integrate layer 4 segmentation at the top of every rack. Addressing the rapid acceleration of software vulnerabilities highlighted by tools like Broad Project Glasswing, Veerappan introduced Cisco Live Protect, an innovative remediation model that allows operators to apply compensating controls directly to Nexus switches to eliminate vulnerability exposure windows immediately without waiting for a scheduled maintenance window. Finally, looking toward future challenges, Veerappan noted that Cisco is actively advancing into phase two of developing quantum-safe secure protocols while transitioning toward agentic ops, a model that utilizes deep reasoning, decades of networking expertise, and cross-domain visibility to shift operations from manual remediation to machine-scale reasoning and automated provisioning.
