Even though they were initially associated exclusively with copyright infringements and, thus, provoked considerable public odium, their good properties supersede and the overlay networking technology is here to stay. On one hand, overlay networks can provide specific applications without being supported by current underlay network, e.g., multicast. On the other hand, the client-server model does not scale in different respects, and many content distributors find it more efficient to deliver their content using overlay networks. For example, free Linux distributions (e.g., Red Hat’s Fedora or Debian) are distributed via BitTorrent. Furthermore, the Internet traffic stemming from overlay-based applications, e.g., Peer-to-Peer (P2P) applications, increases rapidly with the increase of available bandwidth of end-nodes. Therefore, a slow paradigm shift from centrally offered services to services offered by end-nodes is in progress. For today’s Telecommunication Service Providers (telcos) and Internet Service Providers (ISP) the key issue arising is how to control and manage network traffic stemming from such overlaybased applications. As the structure of overlays determines traffic flows in ISP networks, it is highly efficient for an ISP to influence the overlay configuration based on information on their structure. Thus, the management of overlays aims (a) to maximize the benefit for multiple operators/ISPs involved and (b) to increase the capability to withstand faults and balancing the network load. Traditional traffic engineering methodologies are insufficient to satisfy simultaneously the provider’s goal to maximize network usage and the user’s goal to maximize his utility, since most of current overlay networks are deployed oblivious of the underlying physical network Awduche99. E.g., traffic between two nodes in the Telefonica network in Madrid can go via Tokyo, incurring large and unnecessary costs. This is why network operators show a strong interest in influencing overlay network operations and shaping the overlay traffic as to comply with their needs. Within that context, SmoothIT proposes a new traffic management mechanism termed Economic Traffic Management (ETM), which provides for an incentivecompatibility in those interactions foreseen between overlay applications and the underlying ISP networks in order to gain the following measurable impacts: 1. Cost saving for ISPs: lower operation costs, due to ETM-based traffic engineering, lower interconnection costs, since traffic can be kept inside an ISP’s domain, and lower capacity extension cost, since capacity requirements can be forecasted with much higher accuracy. 2. Lower prices for end-users, due to competitive pricing by the ISP, which are enabled by new ETM mechanisms. 3. Better Quality-of-Service (QoS) for overlay-based applications across ISP domains, due to the usage of ETM-based traffic engineering. This leads to an improved media consumption experience for end users.
