Hi dear administrator!
Every time you need to start a proyect of this kind, the first you should do is to launch a Planification design.
This means to make a deep analysis about the current network (if there is one) and the purpose of this new implementation, taking into account the following parameters.
*Bandwith
*QoS
* Applications to be used and vlan implementation
*Scalability, which means
- be able to adapt the network topology (hardware)
- be able to update to new technologies the operation equipement constantly
* Network security
- definition of security policies at the edges of the network.
- VPN and data encryption
- General management best practices.
* Accessibility
- People who si going to access to the network
- Places and mechanisms for access to the network
- Equipement administrators and best practices on the use of passwords.
As an electronic engineer working in a Telecomunication company, I specialize in the start up of new network proyects, providing the desing of the network, including what kind of equipement you have to buy, rules to have the best pratices on the network and a portfolio of recomendations about technology providers (Cisco, Meraki, Huawei and recently, juniper).
Feel free to ask me about my proyects and experience.
Best regards.
