3 Network Traffic Forecast Internal and External Parameters Impacting Traffic Forecast Internal factors affecting Future Traffic Growth Internal Factors 1. New Services 2. Service Decommissioning 3. Traffic Migration 4. Traffic Routing Policy 5. Merger & Acquisition 6. Speed Upgrade Projects 7. Change in On-net / Off-net Traffic External factors affecting Future Traffic Growth External Factors 1. New Internet apps/games/service 2. New Business Development 3. Regional Economic Factors 4. Market Competition / New Providers 5. Seasonal Effect 6. Customer Churn/growth Rate 7. Special Events 2

4 Network Traffic Forecast: A top-down approach New Business Development IT Research Park Estimate potential business customers BI Traffic Data 1 Estimate market share: Customer split between the ISPs Estimate demand by type of services Map all the new services to CO level 2 Traffic Data CO level Capacity req analysis at CO level 3 At each CO level, estimate the additional capacity required At each CO, HW / SW req $$ 4 Capital $$ estimate at CO level 3

5 Project Overview: Network Traffic Forecast Project #1: Mapping Business Intelligence into Traffic Data o Project: Given a set of internal / external traffic forecast parameters, you need to develop a methodology and tool that to convert the business intelligence / data into a traffic level distribution o Category : Undergrad / Grad Project #2: Mapping Traffic Forecast into CO level o Project: Given a network topology, and traffic forecast associated to a set of internal and external parameters; you need to develop a methodology and a tool that can distribute the traffic data among the COs o Category: Undergrad 4

6 Project Overview: Network Traffic Forecast Project #3: Mapping Traffic data into Capital Forecast at CO level o Project: Given a detailed CO level network topology, current capacity parameters, and projected traffic load; you need to develop a methodology and tool that can convert the given traffic load into capital forecast (how much investment is required) o Category: Undergrad Project #4: ISP Traffic Forecast Study o Project: You need to (a) review the major recent research works done in network traffic forecast area, (b) identify whether the exisiting research findings can be effectively utilized in an ISP traffic forecast environment, and identifying the missing links (c) provide a framework that you think would be able to forecast ISP traffic effectively o Category : Grad Survey Paper 5

7 Project Overview: Network Traffic Forecast Project #5: Traffic Forecast for Content Delivery Network (CDN) o Project: Given network traffic forecast (content popularity index), you need to design a Content Delivery Network (CDN) that will both benefit ISP and its customers by brining the contents closer to home / customers o Category : Undergrad / Grad 6

8 Project Overview: Network QoS What is Network QoS Basic Quality of Service (QoS) Parameters o BW Throughout o Latency o Packet Loss o Jitter o MTBF (up-time), MTTR (down-time) QoS in Best Effort Service (Residential Internet Service) SLA, and SLO QoS in Customer Service Management QoS Monitoring in end-to-end Networks Service Specific QoS 7

9 Project Overview: Network QoS Project #1: Traffic Overbooking Ratio (OB Factor) o Project: Given a network topology, a set of capacity parameters, and QoS requirement; you need to design and develop a link capacity threshold strategy to optimize the business objectives o Category: Undergrad Project #2: Proactive QoS Monitoring o Project: Given a network topology, specific service architecture, QoS parameters, and simulated data set; you need to design a prototype for proactive QoS monitoring o Category: Undergrad 8

10 Project Overview: Network QoS Project #3: Network QoS study for ISP services o Project : Given a set of ISP services (such as DSL, VoIP, IPTV etc.), your project needs to investigate the current status of the QoS parameters that are used to measure these services o Category: Grad Survey Paper Project #4: Network QoS study for e-health services o Project : Your project will (a) investigate the current status of the QoS parameters that are used to measure today s ehealth services, (b) analyse the validity of these parameters (c) identify if there is a need to establish a new set of QoS parameters for e-health services. o Category: Grad Survey Paper 9

11 Project Overview: Network QoS Project #5: QoS Measurement for end-to-end networks o Project: Given a specific service architecture and its QoS requirements, you need to design a methodology and tool to measure the end-to-end QoS performance o Category : Undergrad / Grad 10
