Only advanced DPI technology meets future network challenges
In recent years, deep packet inspection (DPI) has evolved from a basic signature-based security mechanism used for identifying threats through pattern matching to an advanced behavioral and statistical analysis tool delivering full insights into IP-based network traffic. DPI software has become a powerful tool to meet new network challenges, playing a central role in today’s internet and network infrastructure. With emerging technologies, 5G, IoT/ IIoT and widespread virtualization on the network and application level, DPI becomes even more important to ensure efficient network operation and the highest security.
Where and why is DPI technology used?
DPI can look for protocol non-compliance, spam, viruses, intrusions, or other defined criteria to decide whether the packet may pass or needs to be routed to a different destination. DPI technology can be integrated into firewalls, routers, SD-WAN solutions, IoT gateways and many other devices to enhance security and improve network management.
To meet future service demands, carriers and enterprises are not only enhancing their network infrastructure for greater speed and quality of service (QoS), but also looking for ways to manage their data flows more intelligently. The key to maintaining integrity, ensuring security and optimizing the efficiency of a multi-Gbps network is a high-performant, efficient and accurate deep packet inspection software such as R&S®PACE 2 that delivers full visibility into IP-based network traffic in real time.
Encrypted traffic intelligence
As most of the internet traffic is now encrypted, a reliable DPI software needs a tool kit of advanced techniques to classify traffic and, for example, determine if an encrypted WhatsApp session is a voice call, a text message, a sent video or the like, with very high accuracy. This requires traditional DPI techniques such as pattern matching to be supplemented by heuristic and statistical approaches as well as machine learning and complex algorithms developed by a team of engineers. These techniques can analyze many flow dimensions, the flow duration, the transfer size, group attributes to parse types of traffic, and identify protocols. It’s also possible to indicate the quality of experience (QoE) of videos using buffer counts, buffer stalls, pauses, bitrate changes and so on.
In the age of ever-increasing network traffic and fast-evolving advanced threats, deep packet inspection is a critical tool for advanced network management and IT security.
