Abstract :
Hybrid content distribution network (HCDN) makes use of the highly complementary advantages of conventional CDN (content distribution network) and pure P2P (peer-to-peer). In HCDN, clients can concurrently retrieve content from both CDN and P2P networks. In this paper, service differentiation is formulated as a constraint optimization problem, in which two critical factors are taken into consideration: quality factor of a link and demand factor of a file. With the convex optimization theory, two bandwidth allocation algorithms, HBAA-P for source peer and HBAA-S for surrogate server, are proposed and proved for service differentiation in the hybrid architecture. Some experimental results are illustrated to make sense of the performance features of our approaches.
