A self-managed network refers to a computer network where the organization or entity takes full responsibility for the configuration, maintenance, and management of the network infrastructure. In a self-managed network, the organization handles tasks such as setting up network devices (routers, switches, access points), establishing network connectivity, managing security measures, monitoring network performance, and troubleshooting network issues.

Here are some key aspects and considerations related to self-managed networks:

1. Network Design: The organization needs to plan and design the network architecture, including the placement and configuration of network devices, IP addressing, subnetting, and network segmentation.

2. Device Configuration: Network devices such as routers and switches require proper configuration to enable connectivity, routing protocols, security features, and Quality of Service (QoS) settings. This involves tasks like assigning IP addresses, configuring access control lists (ACLs), and implementing virtual private networks (VPNs) if necessary.

3. Security: Protecting the network from unauthorized access, data breaches, and malicious activities is crucial. This involves implementing firewalls, intrusion detection and prevention systems (IDPS), virtual LANs (VLANs), and secure authentication mechanisms like WPA2 for wireless networks.

4. Network Monitoring and Maintenance: Regular monitoring of network performance, bandwidth utilization, and identifying and resolving network issues are vital. This can involve using network monitoring tools, analyzing logs, and implementing backup and disaster recovery solutions.

5. Staff Expertise: Managing a self-managed network requires technical knowledge and expertise in networking concepts, protocols, and troubleshooting. It's important to have skilled IT staff or network administrators who can handle the configuration, maintenance, and ongoing management of the network infrastructure.

While self-managed networks provide organizations with control and flexibility over their network infrastructure, they also require ongoing investment in terms of time, resources, and expertise. Alternatively, organizations may opt for managed service providers (MSPs) or outsource network management to specialized companies if they prefer to focus on their core business operations without the burden of network management responsibilities.
