一般来讲DPI知道你是从IP A发送到IP B，但是如果发送的是加密的数据，DPI是看不懂的。但是也有例外，...
Deep packet inspection, which is also known as DPI, information extraction, IX, or complete packet inspection, is a type of network packet filtering. Deep packet inspection evaluates the data part and the header of a packet that is transmitted through an inspection point, weeding out any non-c...
华为的深度包检测技术(Deep Packet Inspection, DPI) 是一种先进的网络管理和安全技术,它允许网络运营商和服务提供商深入检查经过网络的数据包。这项技术不仅能识别数据流量的类型,还能提供更深层次的数据包内容分析。以下是对华为DPI技术的详细分析: 技术原理:DPI技术通过深入分析数据包的头部和有效载荷(payload)来识别...
DPI is normally more effective than typical packet filtering, which inspects only the packet headers. DPI inspects the packet’s data part (and sometimes the packet header) when it goes over an inspection point, attempting to find protocol noncompliance, intrusions, spam, viruses or other predef...
网络深度包检测;包深入检查 网络释义
DPI (Deep Packet Inspection) 深度包检测技术 一、DPI 技术产生的背景 近年来,网络新业务层出不穷,有对等网络(Peer-to-Peer,简称 P2P)、VoIP、流媒体、Web TV、音视频聊天、互动在线游戏和虚拟现实等。这些新业务的普及为运营商吸纳了大量的客户资源,同时也对网络的底层流量模型和上层应用模式产生了很大的冲击,...
DPI(Deep Packet Inspection)深度包检测技术是在传统IP数据包检测技术(OSI L2-L4之间包含的数据包元素的检测分析)之上增加了对应用层数据的应用协议识别,数据包内容检测与深度解码。 通过对网络通讯的原始数据包捕获,DPI技术可使用其三大类的检测手段:基于应用数据的“特征值”检测、基于应用层协议的识别检测、基于行为...
Deep packet inspection (DPI), also known as packet sniffing, is a method of examining the content of data packets as they pass by a checkpoint on the network.With normal types of stateful packet inspection, the device only checks the information in the packet’s header, like the destination...
Deep packet inspection has three significant limitations: It can create new vulnerabilities in the network, even as it provides protection against existing vulnerabilities. While effective againstbuffer overflowattacks,denial-of-service attacksand certain types ofmalware, DPI can also be exploited to facil...
