Group Literature Research and Riverbed Simulation Model

Technologies used in modern enterprise networks

The objective is to perform group literature research and individually build a Riverbed simulation model based on the network architecture given and evaluate the behaviour of network parameters gained by simulating the use cases. The design, implementation and simulation discussion imply the inclusion of graphs and justification of made decisions or the results achieved through the simulation.

1. Perform literature research on the technologies that used in modern enterprise networks.
These technologies are Distributed Denial of Service Protection, Load Balancing and Cloud Virtualization. There are multiple providers of such services, some examples, Amazon AWS, CloudFlare and Akamai ologies. Critically discuss these technologies concerning the scalability and transparenoy of communication, providing examples. Identify two or more commercial risks arising due to the failure of such cloud services. The discussion should be
documented and should be approximately 700 words. The group should consist of two roles risk assessor and upgrade engineer. The upgrade engineer must review the technolagies from a benefit point of view, whilst the risk assessor evaluates the potential threats.

2. Design, implement and simulate your model in the RIVERBED simulator guided by the given network architecture overview. The design requires detailed documentation on the application and performance settings in the RIVERBED Simulator for each user and these settings justifications. Following the implementation, you are required to simulate your scenario for 20 minutes. [NDIVIDUAL TASK]

3. The documentation must contain subnetting schemes for each LAN. Note: You are NOT required to confizure Riverbed to use subnets. You must provide the following: Netwark Address, Broadcast Addres, Usable Addresses, and 1P Address assignments to hosts. You must use at least two classes from Private Address Space.

4. Investigate the behaviour of the network performance in a variety of cases. The analysis must be done regarding your expectations. Discuss the scenario and hypothesize on the possible outcomes of provided use-cases followed by the analysis of the results that were received from the simulation. [INDIVIDUAL TASK]

5. You must review the following:
i. Utilization of a T1 link.
ii. Average FTP download response time
ii. HTTP page response time.
iv. The behaviour of voice and video applications
v. Ethernet delay
vi. Simulate the following use-case: The new call centre office will communicate with Chicago and Sydney offices. It is planned that 10 users will communicate with the Sydney office and 5 users will communicate with the Chicago office. All offices will communicate via the video-conferencing application. Investigate the behaviour of the video-conferencing application.
vil. Evaluate the network performance in a use-case, where you would introduce at least one of the improvements that you have identified. 

Note:
Perform the analysis of the results starting from the first minute. This should be done, to reduce the noise from the data caused by the initiolization of network devices such as routers and Switches which may have an Impact on vour investiaation.
The group assessment should be completed in pairs and must include the following:
1. You must provide the names of all participants who contributed to the group work.
2. Your submission must include exact copies of the group work. 

Deliverables:
A good structure report, which must include the following:
A literature review on the technologies that are used in a provided network architecture and the benefits of usage of cloud services. Refer to Task 1.
Description of the designed and implemented scenarios, including the justifications for the design and choice of performance parameters. Refer to Task 2.
Documentation on the investigation of required features and use-cases, including graphs and analysis of the results of the simulation. Refer to Task 3 and its subcategories.
Based on the results; recommend your choice of consideration to improve the network model.
A critical reflection, which is evaluative and reflective.

Assessment Criteria:
1. Review of technologies and cloud services discussion.
2. Justified design and simulation of the network architecture and applicationmodels.
3. Investigation and analysis of the results. 30%
4. Recommendation of your choice for improvement of network architecture.
5. Critical reflection
