Study Notes
Network Functions and Architectures
- End user devices require direct connectivity for efficient access.
- Traffic policing is essential at the edge of the network to manage data flow.
- Uninterrupted forwarding service is critical for maintaining network performance.
- Packet inspection is necessary to detect and mitigate malicious activities.
- Timely data transfer between different network layers enhances overall functionality.
Core Layer Functions
- The collapsed core layer enforces routing policies in a two-tier architecture.
Cloud and Virtualization Concepts
- Virtual machines run efficiently via hypervisors, enabling virtualization of physical components like CPU, memory, and storage.
- Infrastructure-as-a-Service (IaaS) allows users to install custom operating systems on virtual machines.
- Cloud services contribute to reducing energy costs and promoting telecommuting, supporting environmental sustainability.
- A fundamental of virtualization includes enabling logical network devices to manage traffic between virtual machines and physical networks.
Virtual Machine Operations
- Virtual machines are operating system instances that function independently from server hardware, facilitating resource management.
- Access points connect wireless devices to wired networks, playing a vital role in enterprise connectivity.
Layer 3 Device Functionality
- The primary role of a Layer 3 device is passing traffic between different networks.
SFP Module Interfaces
- Both copper and fiber interfaces using SFP modules provide hot-swappable functionality, allowing minimal service interruption.
Topology Architectures
- In spine-and-leaf architecture, each device is equidistantly separated by the same number of hops, ensuring efficient communication.
- Three-tier network topologies consist of a core layer that guarantees connectivity continuity during device failures, and the distribution layer operates using both Layer 2 and Layer 3 technologies.
