How It Works

Five steps from empty building to full AI Office Ready™ infrastructure — designed, deployed, and operated entirely by inBuilding.

The Architecture at a Glance

One Upstream. Every Building. Every Tenant.

Hardware-enforced at every layer. No software rate limiting. No carrier congestion.

Five Steps

From Empty Building to AI-Ready Infrastructure

1
Dark Fiber & Upstream Connectivity
One upstream · Per-building allocations enforced by physics

inBuilding establishes a single high-capacity upstream at the data center. The aggregation switch assigns one dedicated dark fiber port per building — the transceiver speed is the physical bandwidth ceiling, regardless of software configuration.

Building A: 10G  |  B: 50G  |  C: 100G  |  D: 400G+
Port speed = physical ceiling — no software policing required
2
Building-Wide Fiber Backbone
Installing the physical infrastructure layer

Install a switch with H-QoS policies enforcing per-tenant bandwidth in hardware, or install a spine-leaf architecture for lossless GPU workloads.

3
Core Switching Fabric
Deploying the intelligence of the network

Buildings A–C receive a Nexus 93180YC-FX3 MPoE switch with H-QoS child policies enforcing per-tenant bandwidth in hardware. Building D receives a full spine-leaf architecture for lossless GPU workloads.

Buildings A–C: H-QoS enforcement at line rate
Building D: Lossless fabric with PFC, ECN, and DCQCN
4
Tenant Connectivity Provisioning
Hardware-enforced bandwidth guarantees

Each tenant gets a dedicated connection via H-QoS policies enforced in hardware. One dark fiber run simultaneously serves 1 Gb, 10 Gb, and 100 Gb tenants — no separate carrier circuits per tier.

1 Gb — under $400/mo vs. $800–$1,200 from carriers
10 Gb — under $3,000/mo  |  100 Gb — under $9,000/mo
5
Edge Compute for AI Tenants
GPU clusters inside commercial office space

For AI and HPC tenants, the inBuilding fabric functions as a lossless GPU networking fabric — the same architecture found in purpose-built data centers, now available where engineers actually sit.

Responsibilities

Who Manages What

inBuilding handles the entire digital infrastructure layer. Building owners and tenants have no operational complexity.

inBuilding Owns & Operates

  • Tier 1 upstream and data center aggregation
  • All dark fiber — data center to building and building-wide
  • Core switching fabric and H-QoS configuration
  • Monitoring, SLA enforcement, and performance reporting
  • Tenant provisioning and bandwidth tier changes

Building Owner Provides

  • Main data/telecom room access
  • Conduit access for fiber distribution
  • IDF space on each floor

Tenants plug in and receive connectivity. No configuration, no carrier negotiations.
