Research on P4PCDN Automatic Construction Strategy Based on Network Measurement

ISP must provide the effective information for completing the P4P (Proactive network Provider Participation for P2P, P4P) networking. Aiming at this P4P CDN networking defects, this paper proposes a P4P CDN automatic construction strategy based on network measurement. Using the network measurement subsystem to acquire the key information, the distance and status of the network between the node and the cache node can be measured; the ISP ID the node belongs to can be obtained. Finally around each CDN edge cache node, an autonomous domain can be built automatically. This strategy improves the rationality of P4P CDN node service domain and the stability of P4P CDN service.
