Infrastructure Architecture Blueprints

Architectural layout and implementation directives across core technological disciplines.

🌐 Enterprise LAN & Wireless

HLD Paradigm: 3-Tier Hierarchical Resilient Architecture (Core, Aggregation, Access Stack) with dual multi-chassis uplinks.

[ Edge Router / Internet ] │ [ Core Switch Stack ] ╱ ╲ [ Agg Switch A ] [ Agg Switch B ] ╲ ╱ [ Access PoE+ Switches ]

LLD Execution: Spanning-Tree Optimization, Port-Channels, isolated VLAN profiles, 802.1X NAC, SSID profiles.

🖥️ Enterprise Data Center Architecture

HLD Paradigm: Next-Generation Leaf-Spine low-latency fabric, integrating non-blocking wire-speed elements.

[ Core Spine 1 ] ─── [ Core Spine 2 ] │ \ / │ [ Leaf 1 ] [ Leaf 2 ] [ Leaf 3 ] │ │ │ [ Hypervisors ] [ SAN ] [ Backups ]

LLD Execution: Rack elevations, PDU layouts, fiber optic schedules, inter-VRF transit configurations.

📹 Physical IP Surveillance

HLD Paradigm: Isolated high-throughput surveillance engine connected to highly available central NVR arrays.

[ IP Cameras (4K/PTZ) ] │ [ Edge PoE+ Switches ] │ (10G Uplinks) [ VMS Headends ] │ [ RAID-6 Storage ]

LLD Execution: IOPS calculations, dynamic stream bitrates, camera IP schedules, storage retention plans.
