Network design and implementation
While the details of your network design may differ depending on its scale and complexity, this easy-to-follow framework can guide you in developing and implementing the network design that will work.
1. Identify goals
- Requirement analysis: Outline the specific services and applications that will be used within the network, the number of users, and the requirements for bandwidth, reliability, and latency.
- Bandwidth needs: Assess the required bandwidth to ensure smooth data transmission and acceptable performance.
- Budget and resources: Evaluate the project costs and allocate the necessary budget for purchasing equipment and configuring the network.
Example: For a bank’s network, it’s critical to keep services available all the time. It should be considered when planning a network project at every stage. Contingency plans are required in case something goes wrong. This includes having spare equipment on standby, multiple Internet connection pathways, and implementing dynamic routing and link aggregation protocols. Bandwidth requirements need thorough assessment. Based on all the data, a high-level design is developed, and appropriate equipment is selected. And, of course, the project cost should be estimated.
2. Assess current network
When designing a new network for any organization, take stock of the current network setup. This involves creating an inventory of all the hardware devices, software applications, and network connections currently in use. Knowing your current network helps pinpoint upgrades for the new design.
3. Design network topology
- Outline the physical and logical components of the network, considering factors like cabling, switch ports, WiFi access points, IP addressing, VLANs, and data flows.
- Plan for backup routes and recovery mechanisms to ensure continuous communication in case of failures.
- Develop a monitoring and management system to detect and resolve issues, as well as to scale the network as needed.
Example: When designing a bank’s network, it’s essential to consider the physical hardware (routers, switches, WiFi, etc.), how everything is logically connected, how routing and switching protocols should work, and security measures. Finally, providing a secure way for employees to access the network remotely is needed.
4. Choose hardware and software
Decide on which specific hardware and software components will meet the goal you defined for your network design, ensuring flexibility and considering potential supply-chain issues.
5. Plan implementation
Develop a detailed plan for deploying, configuring, and testing the network, including milestones, change management, transition plans, and ongoing monitoring and maintenance strategies.
Example: Bank network deployment
- Form a team
- Develop high-level and low-level design
- Select and purchase hardware
- Install and configure it in branches and data centers
- Test connectivity and security
- Implement change management and a smooth transition plan
- Ensure long-term security through continuous monitoring and maintenance
The initial network deployment process may appear complex. However, if you outsource it to companies like Innowise, you can access a wealth of expertise and resources that will make this process smooth and beneficial for both your business and your clients.
