The assignment is divided into 2 parts. You may start working with this assignment from Week 5 and submit your answers before Week 10. A single word/pdf file may be uploaded by an individual.in drop box and as such you will be provided with a similarity score. This will be considered when grading the assignment. Note that incidents of plagiarism will be penalized.
You are asked to create a network design for VIT. You have options to choose either
Hierarchical network model or Cisco enterprise composite network model.
Considering your campus, design network with respect to both the models and conclude which one you will prefer for implementation. Use necessary figures and explanations for both the models.
Is the network fully converged?
Is router 1, router 2 or router 3 is missing the route to any network? If yes, mention the router and the missing network.
For this network, suggest a routing protocol and justify your selection.
ITNE3006 Design Network Infrastructure Assignment
1. We compare both cisco enterprise composite network model and hierarchical network model. Based on their provided features, we select the cisco enterprise composite network model to create network design of VIT.
The hierarchical network works on layered architecture. It has three layers namely core, distribution and access layer. The primary or main connectivity device that is the entry point for the entire network, is placed at the core layer. ISP routers, edge routers, manageable switches are placed in this layer. This layer connects second layer, distribution layer. Several routers can be placed at this layer. This layer is responsible for access control, security policies and primarily create a boundary between core and access layer to separate access layer devices. Access layer handles all the types of end user connecting devices such as switch, hub, access points etc. and provide end user connectivity in both wired or wireless networks. This model provides modularity in design, resiliency, easy manageable network hierarchy and flexibility in the network. A sample network design to elaborate this concept is presented here.
The enterprise composite network model separates the entire large network in to smaller functional networks that are called as modules. Modules are further creating a small hierarchical network that connect the end user connecting devices. These modules provide flexibility in design and made the implementation easier to manage. Combined modules, provide high availability, advance security, QoS and easy access management. A sample network design based on enterprise network model, is presented here.
2. A typical switching network design is represented in the below figure. We use cisco enterprise network model in this network designing.
Here are the designing policies used in this design:
