Answer to Question #288405 in Computer Networks for kath

Question

A company wants to deploy 4 new studio offices to their network. the company headquarters in Los Angeles with 50000 users. The other 4 new branches are in Australia, BranchA(10000 users), BranchB(8000), BranchC(6000), and BranchD(4700). Each branch's building has 8 levels and 6 servers on the fifth floor of each branch.

The internet access for each office as well as inter-branch-office networking is crucial. The connectivity between Los Angeles and the cities in Australia is a must. you need to think about cost-effectiveness and creating a VPN for this company. What would be the best choice of network, network topology, and hardware to be used in this example?

Answer 1

Using a virtual LAN (VLAN): any broadcast domain that is partitioned and isolated in a computer network at the data link layer. VLANs work by applying tags to network frames and handling these tags in networking systems – creating the appearance and functionality of network traffic that is physically on a single network but acts as if it is split between separate networks. In this way, VLANs can keep network applications separate despite being connected to the same physical network, and without requiring multiple sets of cabling and networking devices to be deployed.

Using Network address translation (NAT): a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device. One Internet-routable IP address of a NAT gateway can be used for an entire private network.

Hardware: routers, switches
