AntFarm: Efficient Content Distribution with Managed Swarms

Efficient Content Distribution with Managed Swarms

Service Routing in Multi-ISP Peer-to-Peer Content Distribution: Local or Remote?

The popularity of Peer-to-Peer (P2P) file sharing has resulted in large flows between different ISPs, which imposes significant transit fees on the ISPs in whose domains the communicating peers are located. The fundamental tradeoff faced by a peer-swarm is between free, yet delayed content exchange between intra-domain peers, and interdomain communication of content, which results in transit fe...

On P2P systems for enterprise content delivery

In this paper we address the problem of optimizing p2p systems for enterprise bandwidth cost savings. Consider a scenario where an enterprise uses p2p swarming to deliver content to its clients. A content may be a file or a package (bundle) of files. For popular and large content, our work finds that enterprise servers can exclusively rely on the cooperation among the peers in the form of a swa...

AntFarm: Towards Simulated Evolution

The most easily observed ant behavior is workers foraging for food. Foraging workers do not eat the food, but carry it back to the nest, where it is processed and consumed by all members of the colony. In many species, a high degree of coordination and cooperation between foragers is observed (usually mediated by pheromone communication). We would like to understand more about the evolution of ...

Self-organized sorting limits behavioral variability in swarms

Swarming is a phenomenon where collective motion arises from simple local interactions between typically identical individuals. Here, we investigate the effects of variability in behavior among the agents in finite swarms with both alignment and cohesive interactions. We show that swarming is abolished above a critical fraction of non-aligners who do not participate in alignment. In certain reg...
