We demonstrate that professional service providers can provide timely reports on the quality of IPTV service delivery using this system. IPTV delivery-specific metrics are collected at various points in the delivery topology, the residential gateway and the Digital Subscriber Line Access Multiplexer through to the video Head-End. An internet protocol television (IPTV) service provides various contents on demand via television and set-top box with internet line. To achieve the load balancing over the proposed architecture, we suggest a new load-balancing algorithm that considers both the expected and the current load of both contents and servers. The first stage is the contents replication according to their expected load, while the second stage is the content-aware request distribution. The experimental results depict that the proposed algorithm outperforms the two other algorithms in terms of load balance, throughput, and request rejection rate.
