Only advanced DPI technology meets future network challenges
The massive increase in internet traffic and expanding technologies, such as cloud computing, the internet of things, the move to 5G and increased encryption, are challenging network connectivity and security. Deep packet inspection (DPI) is a key technology to master these challenges delivering networks of today what they need most - intelligence. Deep packet inspection is a technique for monitoring network and application traffic at the packet level. In recent years, it has evolved from a basic signature-based security mechanism to an advanced behavioral and statistical analysis tool delivering full insights into IP-based network traffic.
With continuously evolving network protocols and applications, increasing network traffic and fast-evolving advanced threats reliable and up-to-date DPI software is vital to classifying network traffic reliably to ensure efficient network operation and the highest security. Application awareness is key to disclose performance bottlenecks and provide data usage insights in order to improve network performance, security and to optimize policies.
Where and why is DPI technology used?
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. Deep packet inspection 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. DPI helps to reroute mission-critical enterprise applications like CRM tools, without any loss of performance, it helps to achieve a holistic view of networks to stay ahead of threats and embedding DPI software in wireless access points helps network providers to improve the quality of experience for their customers.
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, the best-performing DPI engine delivering full visibility into IP-based network traffic in real time despite encryption and frequent application changes. This makes it a critical tool for advanced network management and IT security.

Encrypted traffic intelligence
As most of the internet traffic is now encrypted, reliable DPI software needs a tool kit of advanced techniques to classify traffic. 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.
