Business Network Strategy: More Cables vs More Switches – The Critical Architecture Decision

Last Updated on July 30, 2025

When planning business network infrastructure, most discussions focus on cable types, switch specifications, and wireless coverage. However, one of the most critical decisions often gets overlooked: Should you run individual cables from every connection point back to a central location or install fewer backbone cables and use distributed switches throughout your facility?

This architectural choice affects everything from initial installation costs to ongoing network management complexity. As businesses add more connected devices and expand their operations, understanding the implications of each approach helps you make informed decisions that align with your business needs, operational requirements, and budget constraints.

The Two Primary Network Architectures

Centralized Architecture: The “More Cables” Approach

In a centralized network architecture, every connection point throughout your facility connects directly back to a main network closet with a large central switch. This traditional approach treats the network like a hub-and-spoke system.

How It Works:
Every workstation, printer, wireless access point, and networked device has a dedicated cable running back to the main distribution frame (MDF). All network intelligence and management occurs at this central location, creating a single control point for the entire network infrastructure.

Key Advantages:

• Simplified network management: All configuration, monitoring, and troubleshooting happen from one central location
• Higher reliability: Fewer network devices mean fewer potential points of failure
• Centralized power requirements: Only the main network closet needs UPS backup power
• Easier security management: Network access control and monitoring from a single point
• Consistent performance: All connections have direct paths to core network resources
• Lower ongoing complexity: Reduces management overhead for smaller IT teams

Primary Limitations:

• Higher cable installation costs: Long cable runs to distant areas increase labor and material expenses
• Larger central switch requirements: Need high-port-count switches that can cost significantly more
• Complex cable management: The Main distribution frame can become crowded with numerous connections
• Distance limitations: Cable runs exceeding 100 meters need to be fiber
• Reduced flexibility: Adding connections requires new cable runs back to the central location

Distributed Architecture: The “More Switches” Approach

Distributed network architecture uses backbone cables to strategic locations and smaller switches to provide local connectivity. This approach brings network intelligence closer to end users and creates a more flexible, scalable infrastructure.

How It Works:
High-capacity backbone cables connect the main network closet to intermediate distribution frames (IDFs) throughout the facility. Local switches at each IDF serve nearby connection points, creating network zones that can operate semi-independently while maintaining centralized coordination.

Key Advantages:

• Lower cable installation costs: Fewer long cable runs reduce installation expenses
• Improved performance: Shorter cable runs and local switching improve network responsiveness
• Flexible expansion: Easy to add connections by expanding local switches
• Modular design: Network grows incrementally as business needs change
• Efficient for high-density areas: Serves many connections with minimal backbone infrastructure
• Better fault isolation: Problems in one area don't affect the entire network

Primary Limitations:

• Increased complexity: Multiple switches require more configuration and management
• Distributed power needs: Each switch location requires electrical power and potentially UPS backup
• Multiple failure points: Local switch failures can affect entire network segments
• Higher ongoing maintenance: More equipment locations need regular attention
• Network monitoring complexity: Requires tools to manage distributed infrastructure effectively

Business Application Scenarios

When Centralized Architecture Works Best

Small to Medium Offices (Under 10,000 sq ft)
Centralized architecture benefits buildings where all areas are within reasonable cable distance of a central location. The simplicity of management often outweighs the additional cable costs in smaller facilities. Consider our UniFi office network blueprint for optimized centralized designs.

High-Security Environments
Financial services, healthcare, and government facilities often prefer centralized architecture for security reasons. Having all network intelligence in one secure location simplifies compliance monitoring and reduces potential attack vectors.

Limited IT Resources
Centralized management benefits organizations with small IT teams. Troubleshooting network issues from one location reduces the expertise required and speeds problem resolution, making it ideal for businesses without dedicated network administrators.

Standard Office Layouts
Traditional office buildings with predictable layouts and standard density requirements work well with centralized approaches, especially when future expansion needs are well-defined and manageable.

When Distributed Architecture Makes Sense

Large Facilities and Campuses
Distributed architecture benefits buildings exceeding 15,000 square feet or multi-building campuses. The cost savings from reduced cable runs often justify the increased complexity of management. Our warehouse network wiring solutions demonstrate practical distributed approaches for large spaces.

High-Density Work Areas
Departments with 20+ workstations clustered together make ideal candidates for local switches. Call centers, engineering departments, and open office areas often fit this profile, where multi-gigabit network solutions can enhance performance.

Manufacturing and Industrial Environments
Facilities with distinct operational zones benefit from distributed switches. Each area can have local connectivity for inventory systems, workstations, and wireless access points while connecting to central resources via backbone connections.

Uncertain Growth Patterns
Organizations with unpredictable expansion needs benefit from the distributed architecture's flexibility. Local switches can be upgraded or added as requirements change without affecting the entire network infrastructure.

Cost Analysis Framework

Installation Cost Comparison

Current market data shows significant variation in installation costs based on approach selection. Understanding these cost factors helps you make informed budget decisions for your network infrastructure investment.

Centralized Architecture Costs:

• Cable materials: Higher total cable length for distant connections, particularly for Cat6A installations
• Installation labor: Additional time for long cable runs and complex routing through building infrastructure
• Central switching: High-port-count switches with advanced features can cost $3,000-$15,000 for business-class equipment
• Cable management: Extensive organization systems in the main closet, including patch panels and rack infrastructure

Distributed Architecture Costs:

• Backbone infrastructure: Fiber optic or high-capacity copper connections between locations
• Switch hardware: Multiple smaller switches versus one large switch, often resulting in lower per-port costs
• Power infrastructure: Electrical work at each switch location, including dedicated circuits
• Environmental considerations: Proper ventilation, cooling, and protection for distributed equipment

Technology Infrastructure Considerations

Power over Ethernet (PoE) Requirements
Modern business networks increasingly rely on PoE for wireless access points, security cameras, and VoIP phones. With Power over Ethernet requirements growing, consider how each architecture handles power distribution:

• Centralized PoE: All PoE power comes from the central switch, requiring higher-capacity power supplies
• Distributed PoE: Local switches can provide PoE closer to devices, reducing power loss over distance
• PoE+ and PoE++: Higher power requirements may favor distributed approaches for efficiency

Cable Infrastructure Planning
Your choice of Ethernet cables impacts both architecture approaches differently:

• Cat6 vs Cat6A considerations: Review our Cat6 vs Cat6A guide for performance and cost implications
• Distance limitations: Cat6 supports 10 Gigabit to 55 meters or 1 Gigabit to 100 meters, Cat6A supports 10 Gigabit to 100 meters
• Future upgrade planning: Consider bandwidth requirements for emerging technologies
