Approach
We were tasked with creating a corporate network infrastructure based on specifications outlining the needs of a fictional company named GreenSoft.
We used the specifications to understand the client’s needs in order to present a concrete solutions analysis document. Analyzing the various solutions on the market allows us to stay up-to-date with the constant evolution of technologies and to present alternatives if needed.
Here is a non-exhaustive list to illustrate this phase with some examples:
| Needs | Solution(s) |
|---|---|
| Connection of the Dublin site (IPv6 Only) to the Internet (Dual Stack) | NAT64 + DNS64 protocols |
| Private virtual link between Dublin and the main headquarters in Fribourg | VPN protocols: GRE or IPsec |
| Private tunnel connection from the Lausanne site to the main headquarters in Fribourg | VXLAN or L2TP protocols |
| Stability and security | Additional equipment (Firewall + Router) with VRRP or HSRP protocols |
Architecture and deployment
Once the analysis is complete and the choice of solutions is defined, the next step is to design the network architecture. This is a crucial step in which we design two representations of the network: the logical and physical diagrams.
These diagrams support the deployment phase and are essential for the smooth progression of the work. It is at the end of this stage that a deployment plan is written to define the order in which the different services must be installed.
