Network Capacity Planning

Prepare your network for future growth with professional Network Capacity Planning services.

As organisations add more users, devices, cloud applications, remote workers, branch locations, wireless systems, and business-critical services, network demand can increase quickly. Without proper planning, this can lead to congestion, slow applications, poor call quality, reduced productivity, and unplanned infrastructure upgrades.

Our Network Capacity Planning services help businesses understand current network usage, forecast future demand, identify potential bottlenecks, and plan upgrades before performance problems begin.

What Is Network Capacity Planning?

Network Capacity Planning is the process of measuring current network usage and forecasting how much capacity will be required in the future.

It helps organisations determine whether existing infrastructure can continue to support:

• User growth

• Additional devices

• Cloud applications

• Remote working

• VoIP and video conferencing

• Wireless networks

• Branch offices

• Data transfers

• Backup traffic

• New business applications

The goal is to ensure sufficient capacity is available without investing unnecessarily in oversized infrastructure.

Why Network Capacity Planning Matters

Network demand rarely remains static.

A business may start with a small number of users and applications, but over time it may introduce:

• Microsoft 365

• Microsoft Teams

• Cloud storage

• Azure Virtual Desktop

• SaaS applications

• Additional offices

• More wireless devices

• IoT systems

• Cloud backup

Without capacity planning, infrastructure may gradually become overloaded.

A structured approach helps organisations prepare for growth rather than reacting after users begin experiencing poor performance.

Router Capacity Planning

Routers must be able to support increasing traffic and routing requirements.

We review:

• Throughput

• CPU

• Memory

• Interface capacity

• Routing tables

• VPN usage

• WAN growth

This helps ensure routing infrastructure can scale with business demand.

VPN Capacity Planning

Remote working can place additional demand on VPN gateways.

We assess:

• Number of concurrent users

• Bandwidth usage

• Encryption overhead

• Gateway capacity

• Peak login periods

• Application usage

This helps ensure remote workers can connect reliably during periods of high demand.

SD-WAN Capacity Planning

SD-WAN environments may use multiple links across different locations.

We analyse:

• Link utilisation

• Application traffic

• Failover capacity

• Branch demand

• Cloud traffic

• Performance trends

Capacity planning helps ensure backup links can support essential traffic if primary connections fail.

Cloud Connectivity Capacity Planning

As organisations move applications to cloud platforms, internet and private connectivity requirements may increase.

We help plan connectivity for:

• Microsoft Azure

• Amazon Web Services

• Microsoft 365

• Hybrid Cloud

• Multi-Cloud

This helps ensure cloud adoption does not create unexpected network bottlenecks.

Microsoft Teams & VoIP Capacity Planning
