Abstract

Embodiments of the present invention provide a message processing method, a DPI network element and a DPI device. The method includes: according to the message characteristics of the first message of the deep packet inspection DPI performed according to the needs of the service flow, determining that the first DPI device is used to perform DPI on the first message; sending to the first DPI device A first DPI request, where the first DPI request includes all or part of the first message; receiving a first DPI response sent by the first DPI device according to the first DPI request, where the first DPI The response includes DPI results. The message processing method, the DPI network element and the DPI device in the embodiment of the present invention can support a network environment in which multiple DPI devices are deployed.

Description

technical field [0001] The present invention relates to the communication field, and more specifically, to a message processing method, a deep packet inspection request network element and a deep packet inspection device. Background technique [0002] With the emergence of network broadband technology, while bringing opportunities to telecom operators, it also brings many problems that need to be solved. Currently, in the bearer network of telecom operators, various new applications are carried on the transmission control protocol / Internet Protocol (Transmission Control Protocol / Internet Protocol, referred to as "TCP / IP") upper-layer network transmission, but operators It cannot be directly sensed, resulting in the gradual pipeline of the operator's network, leading to problems such as difficult business management, content billing cannot be realized, and information security requirements cannot be met. In order to solve these problems, a deep packet inspection (Deep Packet...
