Data Collection System The XBC (X Broadband Company) is an imaginary ISP (Internet Service Provider) based in Denmark. Its strategy is to reach a customer base of some 2 million Internet customers. It has been decided to investigate the feasibility of changing from flat-rate charging to volume based charging, where customers pay a fixed subscription fee for the basic subscription and in addition pays for the amount of data transmitted. In order to support volume based accounting it is needed to have a data collection system which can reliably keep track of the volume of data transmitted by each customer. According to the OSS (Operations Support System) architecture recommended by TeleManagement Forum, such data collection system is useful for supporting other features such as performance management an QoS (Quality of Service) assurance. Therefore XBC wants to undertake a feasibility study to determine the system needed to support such data collection and in particular to establish the expected cost such a system would incur to be able to handle the expected number of customers. The feasibility study should also determine if there are any inexpensive spin-offs to be achieved in supporting additional features than the mere volume based accounting. The XBC broadband network is based on access servers from Cisco (or Juniper, Redback … if the group prefers these alternatives). 8.

Inventory Tracking System The XBC (X Broadband Company) is an imaginary network operator based in Denmark. It is providing DSL (Digital Subscriber Line) services to the Danish population. The DSL services are based on the use of DSLAMs (DSL Access Multiplexer) connected via an ATM (Asynchronous Transfer Mode) network to B-RAS (Broadband Remote Access Servers), providing the access to the XBC IP network. The XBC has a problem with keeping track of the equipment and resources allocated to customers. Therefore XBC want to implement an Inventory Tracking System which can correlate the equipment and resources allocated to customers with the equipment and resources actually deployed in the network. The purpose of such a system is to identify stranded assets and to support a roll-out of network equipment and resources witch is optimal in respect to the growth rate of the customer base. The project should develop a system design and a business case for such a system, i.e. develop the specification needed for management to decide on the actual realisation of the system. 8.

Traffic and Performance Modeling in GPRS Networks Goal of this project is to investigate traffic models for GPRS networks and subsequently use them in simple performance models for network planning purposes. In cooperation with a local operator actual traffic data should be analysed and this analysis should impact the choice of the traffic models and the parameter estimation. Possible steps: Analysis of GPRS architecture and performance impacting factors; Survey of applications and traffic models for wired IP scenarios Analysis of traffic data from operator network with respect to selected properties Traffic model(s) selection and parameter fitting Application of traffic models in the scope of simple performance models for network planning purposes 8.

Traffic Engineering with MPLS Goal of this project is to investigate the usability of MPLS traffic engineering in static and dynamic scenarios. Practical experience with the establishment of such paths (set-up delays, etc.) and with corresponding traffic engineering methods should be obtained in a n experimental set-up using the CISCO routers in the IPLab experimental network ( Possible steps: Survey of MPLS traffic engineering approaches; analysis of MPLS configuration possibilities in the experimental network Development of concepts for static and dynamic traffic engineering with MPLS Theoretical/Simulation analysis of the concept Implementation of s sub-part in the experimental network Development and Documentation of a show-case 8.
