REQUIREMENT

3

  • The HealthCare hospital is a chain of hospitals that has 10 branches all around the country.
  • The main branch is in Colombo, and it has 9 sub branches in Gampaha, Kaluthara, Galle, Matara, Kandy, Jaffna, Anuradhapura, Negombo, and Trincomalee.
  • They share medical reports about their patients with the help of HIPAA with TLS.

REQUIREMENT

4

  • The main branch needs to provide access to 500 IP enabled devices and each sub branch needs to provide access to 200 IP enabled devices.
  • A layer 3 device (Router) needs to place as a backbone device to connect all the branches together, and layer 2 devices to connect all the IP enabled devices to each branch.
  • All the branches need to provide wireless connection to their users by using appropriate devices.

TASK

  • Design a network for the HealthCare hospital chain by using the appropriate devices.
  • Design an IP addressing schema to interconnect all the branches by using an appropriate private IP address range.
  • Suggest the protocols for each layer according to ISO/OSI layered architecture.

CHOOSING PRIVATE IP ADDRESS RANGE

8

172.16.0.0/20

​

    • The main branch needs 500 IP addresses.
    • The other nine branches need 200 IP addresses each.

​

Therefore, this is the optimal range to use to avoid wasting IP addresses.
