Open Linux NOS lineage, OVS/OpenFlow readiness, enterprise fabric features and D-Link value-adds that make this product production-ready across core, DC and industrial use-cases.
D-LinkNOS combines an enterprise L2/L3 stack with modern automation and telemetry primitives — agents and management tooling running natively on the switch.
Overview:
D-LinkNOS runs on a Debian userspace and exposes Linux kernel interfaces — making the switch a first-class citizen in CI/CD pipelines. Operators can run configuration management, telemetry collectors and custom scripts directly on the device. No additional servers or out-of-band orchestration boxes required for day-2 operations.
Why it matters:
Deployments that treat the network as code gain faster rollouts, reproducible configurations and integrated telemetry-driven operations. D-LinkNOS supports common automation frameworks so network changes can be managed using the same toolchains as compute and storage.
Business value: accelerated feature delivery, lower operational friction, consistent lifecycle and monitoring across infrastructure.

Overview:
ToR leaf connecting server racks to 100G spine uplinks. Ideal for dense compute racks and east-west application traffic within an EVPN-VXLAN fabric.
Business value:
Low-latency east-west fabric, simplified automation and predictable microburst behaviour for cloud-native workloads.
Overview:
Campus core delivering active-active gateway services with symmetric forwarding and high availability for multi-building enterprise networks.
Business value:
Seamless failover and simple gateway operations across multi-building campus networks.
Overview:
Edge aggregation for carrier peering, CDN connectivity and ASBR integration. Handles route policy, VRF leaking and controlled boundary exchange.
Business value:
Localized peering and controlled route exchange for multi-homed enterprise and carrier sites.
Overview:
Consolidate DHCP server (10K leases), built-in NAT for labs, and 4K SVI segmentation on one platform. EVPN-VXLAN virtualizes the network from the underlay — enabling isolated tenant or IoT segments at scale.
Business value:
Reduces appliance sprawl, speeds SD-WAN and testbed deployments, and supports large multi-tenant VLAN footprints.
