Study Notes
Network Architectures
Peer-to-Peer Network Architecture
- All devices have equal status and can act as both clients and servers.
- Devices can share resources directly without a central server.
- Suitable for small networks or file sharing among a limited number of devices.
- Environment where centralized control or dedicated server resources are not needed.
Client-Server Network Architecture
- Dedicated servers provide services or resources to client devices.
- Clients request services from servers, which respond to these requests.
- Servers have higher processing power, storage capacity, and specialized software.
- Commonly used in enterprise environments where centralized control, security, and management are essential.
Three-Tiered Network Architecture
- Consists of access, distribution, and core layers.
- Access layer connects end devices to the network.
- Distribution layer aggregates traffic from access layer switches.
- Core layer provides high-speed connectivity between distribution switches.
- Offers scalability, redundancy, and efficient traffic flow in large networks.
Spine-and-Leaf Network Architecture
- Utilizes a leaf layer of access switches connected to a spine layer of core switches in a full-mesh topology.
- Provides high bandwidth, low latency, and scalability for modern data centers.
- Offers better east-west traffic handling compared to traditional three-tier architectures.
- Ideal for cloud environments and high-performance computing clusters.
Mesh Network Architecture
- Each device is connected to every other device, creating multiple paths for data to travel.
- Offers high redundancy and fault tolerance.
- Data can take different routes if one link fails.
- Commonly used in wireless networks, IoT deployments, and ad-hoc networks.
Hierarchical Network Architecture
- Organizes network devices into multiple layers based on their functions and importance.
- Helps in efficient network management, scalability, and troubleshooting.
- Often seen in large enterprise networks with distinct core, distribution, and access layers.
- Provides clear segmentation of network functions for better control and security.
Software-Defined Networking (SDN)
- Separates the control plane (network intelligence) from the data plane (packet forwarding).
- Allows centralized management and programmability of network devices through software controllers.
- Enables dynamic network configuration, automation, and policy-based control.
- Revolutionizing network management and deployment in modern data centers and cloud environments.
