Networking protocols and architecture
Assignment task Description:
You are a network engineer. You need to design a network for this business site.
Task1 :
Design a network based on the specifications and the floorplan below:
Specifications:
Room 5 should have the comms.
Each office is equipped with 6 desktop PCs. Assume that all PCs operate critical functions.
In the comms room there is a need for at least one hardware firewall to be connected to the border router.
Most devices should be in the comms room. They will need racks. No rack can be installed in any room apart from room 5.
The LAN has to be 100% redundant in the case of a single point failure. Redundancy is critical. In the case that one of the circuits fails another one must be up. Address this in writing.
The network diameter is not a concern.
In the design include the full 3 layers of the hierarchical model covered in the lectures.
At this stage of the project there is no need for any configuration of the devices.
Cost is not a factor. That does not mean using a carrier class router when you only need an enterprise class router or using a 48 port switch when you need a 24 port one.
You have to consider scalability for the future and address it in writing.
There is an 40 Gbps WDM connection to the main premises of the organization. Describe and include all the equipment that would be present in your LAN only and not in the other site.
There IS ONE 10GE connection that will need to be connected to an ISP provider router. Include the router in your diagrams. This connection comes to the comms room from the ISP buildings.
You do not have to describe the software needed. For example, OS or VM technologies.
Task2. Design an Optical network able to connect the LAN in task 1 with the main premises of the organization.
