Manage Networks
This service outsources the responsibility for the design, implementation, monitoring, and maintenance of an organization’s network infrastructure to a specialized provider. The objective is to guarantee secure, high-performance, and always-available connectivity, both for physical sites and for remote users.
📡 What Does the Service Cover?
The managed network service covers all the components and processes necessary for the network to function as a “utility” within the company: reliable, transparent, and worry-free for users. It encompasses the following areas:
- Physical and Virtual Network Infrastructure: The provider takes charge of the comprehensive management of all network hardware. This includes the configuration, updating, and maintenance of firewalls, routers, switches, and Wi-Fi access points . They also manage Wi-Fi network controllers and any virtual network infrastructure (such as VPCs in the cloud) .
- Connectivity and Routing: It ensures that data flows correctly, both within the local network (LAN) and externally (WAN and the Internet). This involves managing routing protocols (such as BGP or OSPF), configuring Virtual Private Networks (VPNs) for remote employee access, and potentially managing carrier circuits (such as fiber or MPLS lines) .
- Perimeter and Access Security: Security is a central pillar. The service includes the management of next-generation firewalls, Intrusion Prevention/Detection Systems (IPS/IDS), and network segmentation to isolate different types of traffic (e.g., corporate data, guests, IoT devices) . Secure access protocols, such as 802.1X, are also implemented and managed to control which devices can connect to the network .
- Monitoring and Performance: The provider supervises the network continuously and proactively. Critical metrics such as bandwidth usage, latency, packet loss, link performance, and device availability are monitored . This allows for the detection of bottlenecks and anticipation of potential saturation .
- Support and Incident Resolution: Users and the internal IT department have a point of contact to report connectivity issues. The provider is responsible for resolving incidents, ranging from a single user’s connection problem to widespread network outages .
⚙️ How Does It Work Technically?
The operation is based on centralizing control and automation to ensure the stability and security of the entire network infrastructure.
- Network Design and Architecture: The service begins with a network design tailored to the organization’s needs. The provider’s engineers define the network topology, switch hierarchy, routing policies, and IP addressing schemes (subnetting) to create a solid, scalable, and secure foundation .
- Orchestration and Centralized Management: Administrators use unified management platforms (such as Cisco Meraki, Aruba Central, or SD-WAN controller-based solutions). Through a central cloud console, they can:
- Configure and provision new devices remotely (zero-touch provisioning model).
- Apply security and Quality of Service (QoS) policies consistently across all organization sites from a single location .
- Update the firmware of all firewalls, switches, and access points in a coordinated and scheduled manner .
- Software-Defined Wide Area Networks (SD-WAN): Many modern managed network services are based on SD-WAN technologies. This allows the provider to create a more intelligent and cost-effective WAN. The SD-WAN controller can dynamically route traffic across multiple links (MPLS, broadband, 4G/5G) based on performance and application priority (e.g., sending VoIP traffic over the lowest-latency link, even if it is the cheapest) .
- Proactive Monitoring and Automated Alerts: The provider deploys agents or uses standard protocols (like SNMP and NetFlow) to collect data from all network devices. This data is analyzed for anomalies. If unusual behavior is detected, such as a switch starting to drop packets or a Denial of Service (DDoS) attack, an alert is generated so the provider’s engineers can intervene before the end-user experiences a service outage .
- Backup and Disaster Recovery: Periodic backups of the configurations of all network devices (switches, firewalls, routers) are performed. This allows for rapid and predictable recovery in case of hardware failure, simply by replacing the physical device and restoring its configuration from the backup .
In summary, the “Managed Networks” service turns the network into a reliable, high-performance business asset. The provider acts as an external team of network engineers who design, implement, monitor, and protect all connectivity, allowing the organization to focus on its business without worrying about the technical complexity of its network infrastructure.
