深度业务感知与电信网P2P业务

分析了深度业务感知的需求与现状,及其用于识别P2P的应用;对比了现有网络和NGN的区别,总结了运营商应对P2P的措施及各措施的优缺点,以及运营P2P的可能性和必要性。分析了深度业务感知现有技术的优缺点,明确了深度业务感知未能完全达到电信级要求的背景,提出了电信运营商介入P2P运营的具体方式。该运营方法与传统方法的区别在于合理利用了P2P技术的优点,是一种融合各方优势的运营模式,深度业务感知技术在其中得到了应用。

Deep Packet Inspection and P2P Service in Telecommunication Network

The requirement and current status of deep packet inspection are analyzed with applications in Peer-to-Peer (P2P). The difference of traditional network and Next Generation Network (NGN) is presented, and the operator's measures of managing P2P are also summarized. The possibility and necessity of operating P2P are also discussed. After the analysis of current Deep Packet Inspection (DPI) technology, the fact that DPI can not satisfy the telecommunication level requirement is pointed out. A concrete mechanism of telecommunication operator dominating P2P service operation is proposed. This mechanism is different from traditional method in utilizing the superiority of P2P technology properly and synthesizing every participant's advantage.
