DPI takes the technology further by enabling the learning system to look inside and see the contents of information traveling within the network. DPI is also used for the detection and interception of viruses and other forms of malicious traffic to help keep an enterprise network safe. DPI overall is used in network management to streamline the flow of network traffic as certain traffic may have priority over basic web browsing, for example.
Integration of sparse singular vector decomposition and statistical process control for traffic monitoring and quality of service improvement in mission-critical communication networks

DPI examines the contents of packets passing through a so-called inspection point within a network, and searches for anything out of the norm. Although DPI can be used to detect QoS problems, its major utility is to ensure network security by detecting instructions, viruses, spams, and non-compliance of contents with regulation. Various DPI systems and techniques have been developed. For example, SNORT (Roesch, 1999) is a well-known open-source system that can detect various types of worms, attacks, and probes using protocol analysis, and content searching and matching. Smith et al. (2008) proposed a DPI technique that uses regular expression with extended finite automata. Focusing on QoS, Cascarano et al. (2011) proposed and validated optimizations for DPI techniques to accelerate network monitoring and traffic classification on high-speed networks. There are several drawbacks in using DPI for QoS:DPI often requires costly dedicated devices to track, unpack, and analyze real-time packets.DPI can be time-consuming, especially with large-sized packet contents (e.g., audio, video), which makes it unsuitable for real-time QoS monitoring.As DPI examines packet contents, there is a profound concern about privacy.Due to the privacy concern, more and more network protocols such as HTTPS, SFTP, and SSL have been designed to protect private contents from being examined by DPI.
