Network TCO & ROI difference
Network TCO includes costs associated with Day 0 to Day N operations, such as hardware, software, and personnel.
Return on Investment (ROI) is a superset of TCO that includes the cost of benefits realized from an efficient TCO.
By calculating ROI and TCO, businesses can better understand the cost-benefit analysis of their network infrastructure.
What are the components of Network TCO?
Network TCO does not include staff and time costs for hardware refreshes of wireless or wired infrastructure (every three-five years).
Business Value Assessment
Organizations across different industries are realizing the business, TCO, and ROI value of NaaS.
What are the Wi-Fi configurations across a college campus?
Selecting the optimal Wi-Fi configuration for a college campus hinges on several elements such as campus size, user count, usage variety (academic, recreational, administrative), and campus layout. However, these are some general recommendations for a robust campus Wi-Fi setup:
Wireless LAN (WLAN) Configuration
Description: Devices communicate with a central gateway or controller.
Strengths: Provides a stable and centralized way to manage traffic. It’s scalable, making it suitable for large campuses. Administrators can easily manage security settings, update firmware, and monitor traffic through a central dashboard.
Mesh Network Extension
Description: Nodes (or access points) interconnect with each other, allowing data to hop from one node to another to reach its destination.
Strengths: Offers high resilience and redundancy. If one node fails, the network can still operate using other nodes. This topology can cover large areas, like a sprawling campus, and can automatically reroute data for the best path, ensuring consistent connectivity.
Point-to-Multipoint Bridge Outdoors
Description: A central wireless access point communicates with multiple other access points.
Strengths: Effective for connecting multiple buildings on a campus without laying physical cables. It provides a stable and centralized communication channel across vast distances.
Point-to-Point Bridge Outdoors
Description: Connects two locations using a wireless link.
Strengths: Ideal for connecting two campus buildings that are separated by physical barriers, such as roads or rivers. It’s a cost-effective way to bridge two points without the need for extensive cabling.
Repeater Extension
Description: Extends the range of the wireless signal by rebroadcasting it.
Strengths: Useful for campuses with architectural features that impede Wi-Fi signals. It can effectively push the signal to more distant or hard-to-reach areas.
How is Network ROI calculated?
Network Return On Investment (ROI) is the relationship between the total return on the network and the total network TCO. The total return on the network includes cost savings from efficient network deployment, including the following intangible benefits:
Cost savings, including a decrease in hard costs, efficiencies via fewer man-hours spent on tasks, and the elimination of money spent on additional tools.
Productivity increases through lower downtime costs, fewer man-hours spent on troubleshooting, and streamlining personnel numbers assigned to specific network tasks or project management.
Risk reduction due to improved risk and compliance management. This includes reduced cost of network breach and fewer man-hours spent reacting to security threats and alerts.
How Does a Consumption Model Affect Network TCO?
The cost model of today’s networks is complex. It involves many stages, including network planning, procuring, deploying, managing, and securing. Each requires different tools with their own costs.
Consumption models centered around “as a service” allow organizations to shift network costs from a CapEx to an operational expense (O
pEx) model. This improves network cost efficiency and predictability.
Network as a Service (NaaS) consumption models offer the ability to scale network services up or down as needed to meet changing business needs. By paying only for what is used, network costs are further reduced.
