Network Design Overview

Overview of network system design and services for both headquarter and branch.

Section

Network Services

Work From Home

  • Employees working from home can access the company network with a VPN.

Branch Connection

  • Connecting between headquarter and branch with WAN Internet ISP.

Internet

  • WLAN / LAN for every department.

Data Center

  • For storing information in organization.

3-Tier Topology Architecture

The architecture used in the design is 3-tier architecture, consisting of the core layer, the distribution layer, and the access layer.

3-Tier Network Topology Architecture

Core Layer

  • Considered as the back bone of networks

Distribution Layer

  • Works as the bidge of Access Layer and Core Layer

Access Layer

  • Connected to the end devices (Computers, Printers, Servers etc)

Benefits

  • Redundancy: Multiple links across multiple devices provides better redundancy. If one switch is down, we have another alternate path to reach the destination.
  • Scalability: Easily expand network by connecting more access switches in access layer.
