I need a bank network design that meets the following requirements: The bank has - offices on the 3rd and 4th floors of PrincipalBank, - branches at Abank, Bbank (ground floor), CBank, Dbank- ATMs at the train station, on principal street, at metro, and at anotherShop, respectively at each branch. It requires: - data communication - voice communication - appropriate security Total number of network users: Approximately 50 employees. Future expansion: Provide for the possibility of 2 more branches and more ATMs. Unified, secure network that interconnects all locations (head office, branches, ATMs). ATMs connected via dual connection (2 ISPs); those in branches can also use the connection of the respective branch. Telephony: combination of traditional + mobile telephony. A unified VoIP solution is required. The cabling infrastructure will be completely redone at all locations (in steps).The locations are described by sketches (attached). An updated security solution is requested (e.g., centralized firewall, VLANs, end-to-end encryption). The existing Active Directory will be used for centralized authentication. Compliance with standards (e.g., ISO 27001 / PCI-DSS) is possible but not a priority in this project. Maximum allowable downtime: 10 minutes during operating hours. Required availability: > 99.99% annually. Request for proposals for redundant solutions (e.g., double VPN, ISP backup, etc.). The applications are web-based and run on owned servers in the data center (DC). Each agency also has a local server, some with additional storage for off-site backup. The backup is managed at the DC level, but a traffic of 1 TB daily to off-site locations is anticipated.
