Switches & Routers

Switch & Router by Service Providers

Switches are networking devices that connect multiple devices within a LAN (Local Area Network) and enable communication between them.

Types of Switches

Unmanaged Switches

- Plug-and-play functionality
- No configuration required
- Ideal for small networks with minimal traffic

Managed Switches

- Allows custom configuration and monitoring
- Offers features like VLANs, Quality of Service (QoS), and port mirroring
- Suitable for larger or more complex networks

Layer 2 vs. Layer 3 Switches

- Layer 2: Operates at the data link layer and forwards traffic based on MAC addresses.
- Layer 3: Incorporates routing capabilities and works with IP addresses.

PoE (Power over Ethernet) Switches

- Delivers power and data over a single Ethernet cable. .
- Commonly used to power devices like IP cameras and access points.

Use Cases

Small businesses

Unmanaged or simply managed switches.

Enterprises

Managed switches with Layer 3 functionality for enhanced scalability.

Types of Routers

Home Routers

- Connect homes to the internet
- Built-in Wi-Fi capability

Enterprise Routers

- Designed for high performance and scalability
- Includes advanced features like VPN support, firewalls, and QoS

Core Routers

- Operate within the backbone of a large network, managing high volumes of data.

Edge Routers

- Operate at the network boundary, managing traffic between internal and external networks.

Virtual Routers

- Software-based, offering flexible deployment options in virtualized environments.

Use Cases

Home and small offices

Home routers or entry-level enterprise routers.

Data centers

Core and edge routers for efficient traffic management.

Types of Access Points

Standalone APs

- Operate independently
- Best suited for small environments

Controller-Based APs

- Managed centrally through a controller
- Ideal for larger, enterprise-level deployments

Cloud-Managed APs

- Managed via a cloud interface
- Enables remote configuration and monitoring

Mesh APs

- Work together to provide seamless Wi-Fi coverage over large areas.

Key Features

Dual-Band/ Tri-Band

Support for multiple frequency bands (2.4 GHz and 5 GHz).

MU-MIMO

Supports simultaneous connections for multiple devices.

Wi-Fi Standards

Compatible with Wi-Fi 5, Wi-Fi 6, and newer standards.

Use Cases

Small businesses

Standalone or mesh APs for simple setups.

Enterprises

Controller-based or cloud-managed APs for advanced management.

Public spaces

Mesh APs for seamless and broad coverage.

Key Considerations for Deployment

Scalability

Choose devices that can scale with your network.

Performance

Assess bandwidth and traffic-handling requirements.

Management

Decide between centralized and decentralized control.

Security

Ensure support for encryption, firewalls, and secure protocols.
