Local IP network in a district of Beijing after 10 years of use , in many ways , has been unable to meet customers' growing network needs in order to better serve the local customers , launched for business transformation broadband value-added products , the imminent transformation of the local network . The papers for the local network of the status quo , in-depth analysis to identify the main problems of the original network , under which comparative analysis of several mainstream access technology today to identify a suitable transformation technology EPON technology . On the basis of theoretical analysis of EPON technology , combined with the local broadband demand , develop a local network transformation program and implement . After the completion of the transformation of the local network , the paper how to carry IPTV services are analyzed and discussed , with a focus on IPTV bearer network networking technology . The paper has a major problem in the choice of on -demand hosting technology , multicast replication point and user authentication , network QOS EPON IPTV services support solutions for carrying focus . According to the analysis of the results , considering the status of the network , user requirements , and other factors , and learn from some of the existing successful IPTV operator program finalized CDN technology bearer on demand service , multicast replication tap in the OLT to take the set-top box curing private address and SR binding does not authenticate IPTV business hosting program . Paper - based work , through collaboration with the superior network department and the engineering department , the existing network optimization and adjustment , so you can carry IPTV services , and related test after deployment . The thesis also work to do in the future outlook. Network transformation optimization to solve a series of problems that exist in the local IP network can carry and make IPTV services to meet customer needs , made ??a certain contribution to the better development for the branch .
