PTN 网络 QoS 技术应用分析

摘要

PTN 网络服务能力较强，能够根据客户业务特性平衡服务质量和带宽耗用。PTN 网络以分组交换为核心，将传统的分组城域网改变成端对端的运用级传送网。PTN 网络研究对提高网络服务质量、促进网络技术发展具有重要意义。PTN 网络支持层次化的 QoS 技术应用，能够提高网络服务质量。%Packet Transmission Network (PTN)is very powerful and it can balance quality of service against band-width occupancy according to customer service features.With fundamental feature as packet switching,PTN changes tradi-tional Packet Metropolitan Networks (PMN)into end-to-end applicable transmission network.Research on PTN has sig-nificance in improving service quality of network and promoting development of network technology.PTN supports hierar-chical QoS technology which can improve service quality of network.
