ASN DPI

Deep Packet Inspection (DPI) is a powerful technique that analyzes network traffic at the packet level, going beyond basic header inspection to examine the payload—the actual data being transmitted.

Application, Protocol, and Category Identification with DPI

ASN Deep Packet Inspection enables precise identification of 2,700+ applications and 9,000+ subcategory applications, and their attributes by analyzing network traffic in detail. This capability allows organizations to know exactly which apps are running—whether it’s video, audio, gaming, file transfer, or chat—along with the underlying protocols they use. Categorizing traffic helps in applying tailored policies for security, bandwidth allocation, and compliance. By understanding both the app and its category, enterprises and telcos can optimize network performance, enforce acceptable use policies, and gain valuable insights into user behavior and traffic trends

DPI Benefits for Telcos

For telecom operators, ASN DPI delivers detailed application, protocol, and category identification—covering over 2,700+ apps—combined with critical session KPIs such as average, max, and min bandwidth, uplink/downlink latency, and packet retransmissions. This data helps telcos monitor how many users are engaging with each app and how network resources are being consumed in real time. By correlating user behavior with network performance metrics, telcos can optimize bandwidth allocation, improve quality of service for high-priority applications, and quickly troubleshoot performance issues. Additionally, rich metadata like HTTP hostnames and user-agent information aids in refining subscriber analytics, enabling personalized service offerings and efficient network management.

DPI Benefits for Data Centers/Enterprise

In data centers and enterprise networks, ASN DPI combines accurate app, protocol, and category identification with detailed session metrics—such as bandwidth usage, latency, and packet loss—to provide deep visibility into application performance and user experience. Tracking how many users access specific applications and the bandwidth consumed per session allows IT teams to optimize resource allocation and enforce security policies effectively. Latency and retransmission data help identify network bottlenecks or faulty links, enabling proactive issue resolution. Supplemented by metadata like HTTP URLs and user agents, this granular insight empowers enterprises to manage complex traffic flows, ensure compliance, and enhance overall network reliability and efficiency.

DPI Dynamic Upgrade: Always Stay Current:

In a fast-changing digital landscape where new applications and protocols constantly emerge, a static DPI quickly becomes outdated. ASN-DPI addresses this challenge with a robust DPI dynamic upgrade mechanism, allowing its detection engine and protocol signature database to be updated on the fly—without service interruption or the need for full software redeployment.
