MPLS – VPN Assessment Part 1 - Design and Planning
About this assessment:
These assessment tasks provide an opportunity to demonstrate the competencies covered in the IT Networking and Telecommunications Network Engineering MPLS-VPN subject.
You are allowed to refer to your text books, notes and the Internet during the Assessment.
The documentation and research work must be entirely your own. The ACIT/IFTV academic honesty policy should be read and understood.
Successful completion of this assessment contributes towards attaining competency in the following:
ICTTEN610 Design and configure an IP-MPLS network with virtual private network tunnelling
ICTTEN612 Design and manage internet protocol TV in a service provider network
ICTPMG611 Prepare a detailed design brief
ICTTEN611 Produce an ICT network architecture design
ICTNWK529 Install and manage complex ICT networks
Scenario
Pacific Internet Solutions, a multinational Internet Service Provider (ISP) offers a range of internet services to customers. The company also offers Layer 3 VPN's and Virtual Private LAN Services (VPLS) to corporate customers. The company has recently secured a contract with a major provider of pay (cable) television to deliver IPTV to its customers. Pacific Internet Solutions needs to incorporate efficient delivery of IPTV services into its delivery capabilities. The company has not previously provided multicast services. The current network only supports unicast services. The company is in need of an efficient IPTV delivery method.
Pacific Internet Solutions expects that after IPTV is available to subscribers its number of subscribers will increase from the present number of 20,000 to 100,000 over the next 5 years.
Requirements
1. You are required to design and implement Virtual Private LAN Services (VPLS) to meet the requirements of corporate customers.
2. You are required to design an end to end IPTV functional architecture and implement the core network infrastructure using MPLS. The design should minimise Pacific Internet Solutions costs by reducing bandwidth requirements while maintaining a high level of customer experience by providing high quality video and fast channel changes.
Tasks
You are required to prepare network diagrams. You may use Visio or any other drawing/graphics software. The final drawings must be submitted as a pdf.
1.Produce a network diagram of a baseline layer 3 MPLS VPN network within the service providers network. References - Juniper MPLS network diagram Lab 6 part 1
2.Produce a network diagram of a layer 3 MPLS VPN network that shows the connectivity between the Provider Edge router and the Customer Edge router at each end of the VPN. References - Juniper MPLS network diagram Lab 7
3.Produce a network diagram of a Mulitcast MPLS network that would be suitable for IPTV distribution. References - Juniper Junos MPLS and VPN's course notes chapter 13
4.Produce a functional diagram of an IPTV network showing network architecture from the IPTV standards bodies. Include the broadband forum standard that relates to each functional component. Provide a detailed description of what each functional area does. References - Delivering Residential Services Using Juniper, Driving_the_Costs_out_of_IPTV
Submission requirements
1.The written tasks must be completed on a word processor and submitted to the learning portal in word or pdf format.
2.The drawing tasks can be completed using Visio or any other drawing tools and submitted to the learning portal in pdf format.

Requirements
1. You are required to design and implement Virtual Private LAN Services (VPLS) to meet the requirements of corporate customers.
2. You are required to design an end to end IPTV functional architecture and implement the core network infrastructure using MPLS. The design should minimise Pacific Internet Solutions costs by reducing bandwidth requirements while maintaining a high level of customer experience by providing high quality video and fast channel changes.
Your task is to redesign the network infrastructure for Pacific Internet Solutions so that it meets the business requirements for the organisation, and to write a detailed proposal which you will submit to Pacific Internet Solutions for consideration.
The questions below will guide you through some of the things you need to consider for your proposal. You need to answer the questions and then write your proposal.
Question 1.
Describe the function and operation of a Virtual Private LAN Service (VPLS). References - Juniper Junos MPLS and VPN's student guide- Chapter 17
Question 2
Describe the different sources of video content accessed by subscribers (end users) and the impact/challenges that each of these have on Network Service Providers. References - Delivering Residential Services Using Juniper- Chapter 1
Question 3
Estimate the IPTV bandwidth required to service an area with 2000 subscribers. How can bandwidth requirements be contained as subscribers in the area increase? References - IPTV Bandwidth Management Juniper
Question 4
Describe how content caching can reduce bandwidth requirements and improve customer experience. Describe a typical caching infrastructure architecture - you may use a diagram if needed. References - Delivering Residential Services Using Juniper- Part 4
Question 5
You are required to write a design proposal to Pacific Internet Solutions. Your proposal must provide the following:
• an assessment of the client's business problems, opportunities and objectives
• an assessment of the client's current needs and possible future needs
• a detailed list of business requirements that must be met by the new network design including the need to contain bandwidth requirements while maintaining a high level of customer experience by providing high quality video and fast channel changes.
• an explanation of why the current network configuration does not meet the business requirements
• a prediction future network demands and the impact of this on the proposed network design. Determine estimated network traffic and planned growth
• a description of the network design that you propose presented in a clear and logical fashion. Provide advice to client on reasons for your design choice. Inform the client of design limitations, performance expectations and possible unanticipated outcomes
Document the network design and present documentation to appropriate person (your instructor) for approval. Present the design in a clear and logical fashion. The most important idea to keep in mind is that the goal of any proposal is to convince potential clients to award you their contracts.
Submission requirements
1. The written tasks must be completed on a word processor and submitted to the learning portal in word or pdf format.
