Abstract In the client-server model predominant in today’s Internet, the load on a server has a significant impact,on the level of service perceived by its clients. In particular, given that a server is connected to its clients via an access link of finite capacity, the data transfer rate to each of its clients dropsinversely as the number of clients served by the server. This limitation significantly hampers,the scalability of such a setup, especially when long-lived connections are involved in the transfer of large files. It is now,commonplace,for a particular piece of content on the Internet to experience,a sudden,spike in popularity,and hence also in request rate. Such an occurrence, called a “flash crowd” in Internet parlance, is difficult to address via adjusting the provisioning level alone, as it may come and go so quickly for administrative,actions to be taken. To mitigate the problem of theflash crowd, many solutions have beendeveloped. Some of them involve setting up a load-balancing infrastructure, while others rely upon,the altruism of clients to provide,additional capacity to handle the increased load. Inthis thesis,we describe a novel hybrid approach, based onthe technique of swarming, for scaling up the delivery of large files to many clients. Our design allows machines on the Internet to contribute,their bandwidth,resources even when they are not interested in the content being disseminated. These peers, known as helpers, are specially tuned to maximize their upload rates while keeping their own,download,rates to a minimum.,We evaluate our approach through

    • ...We have developed a new cooperative downloading protocol which makes use of social groups, where members who trust each other cooperate to improve their download performance (See Figure 4). The idea of download with the help of others was first introduced in [16], where altruistic peers contribute their bandwidth by joining a swarm even if they are not interested in the content being distributed in this swarm...
