An Empirical Study on the Interactions Between ALTO-Assisted P2P Overlays and ISP Networks
Source: University of Surrey
The recently proposed Application Layer Traffic Optimization (ALTO) framework has opened up a new dimension for Internet traffic management that is complementary to the traditional Application-Agnostic Traffic Engineering (AATE) solutions currently employed by ISPs. In this paper, the authors investigate how ALTO-assisted Peer-To-Peer (P2P) traffic management functions interact with the underlying AATE operations, given that there may exist different application-layer policies in the P2P overlay. By considering specific P2P peer selection behaviors on top of a traffic-engineered ISP network, they conduct a performance analysis on how the application and network-layer respective performance is influenced by different policies at the P2P side.
