Сubro Deep Packet Inspection (DPI): In-depth Traffic Analysis

In today’s digital world, network traffic volume is growing exponentially, creating new challenges for organizations in traffic management, monitoring, and data analysis. According to Cisco’s report, by 2025, global IP traffic will reach 2 zettabytes per year, and the number of connected devices will exceed 30 billion. This rapid growth increases the risk of cyber threats, loss of data control, and overloading security systems.

Many enterprises face the problem of “blind spots” in network traffic, where traditional analysis methods (such as header filtering) do not provide a complete picture of network activity. At the same time, 70% of threats are hidden in encrypted traffic, making their detection difficult without deep packet inspection.

The solution to this problem is Deep Packet Inspection (DPI)—a method that allows organizations to analyze network traffic at the application level (L7), ensuring complete transparency and control. DPI helps detect hidden threats, optimize network resources, and enhance security without compromising performance.

What is Deep Packet Inspection (DPI)?

Deep Packet Inspection (DPI) is a network traffic management and analysis method that allows detailed inspection of data packets transmitted across the network. Unlike traditional filtering methods, which only check packet headers, DPI examines the actual content of the packets, enabling organizations to:

• Identify and classify applications and services at the application layer (L7) of the OSI model.
• Detect anomalies and potential threats in network traffic.
• Apply traffic management policies based on packet content.

Challenges in Data Analysis

Modern organizations, including Communication Service Providers (CSPs), enterprises, and government institutions, face several challenges in data analysis:

• Increasing data volume: Continuous growth in data volume complicates storage, processing, and analysis.
• Security enforcement: The need to protect confidential information and comply with regulatory requirements.
• Network performance optimization: Maintaining high-speed and reliable data transmission.

To address these challenges, organizations actively seek ways to reduce the amount of data sent to monitoring systems without losing critical information.

Cubro DPI Solutions

1. EXA6400

The EXA6400 is a powerful network device that provides:

• Filtering and deduplication: Eliminates duplicate packets for traffic optimization.
• Aggregation: Combines traffic from multiple sources for simplified analysis.
• Load balancing: Distributes traffic across multiple monitoring tools for increased efficiency.

This device ensures efficient traffic management and enhances network performance.

2. Cubro Optical TAP

The Optical TAP is a fully passive device that does not interfere with active traffic and provides:

• Continuous monitoring: Ensures a copy of traffic is available for analysis without affecting the main data flow.
• High reliability: No impact on network performance, even in the event of TAP failure.

This is an ideal solution for secure and reliable network traffic monitoring.

3. Cubro Servers with NPU/Smart NIC

Servers equipped with Cubro’s NPU/Smart NIC can analyze traffic in real time, providing:

• User and application statistics: Detailed insights into network usage.
• Application metadata filtering: The ability to apply management policies based on specific applications.

Even if traffic to the user is blocked, analytical functions continue to work, ensuring continuous monitoring.

Use Cases for DPI

Deep Packet Inspection is widely used in various industries, including:

• Network management: Traffic optimization and Quality of Service (QoS) assurance.
• Cybersecurity: Threat detection, intrusion prevention, and traffic anomaly detection.
• Application performance analysis: Identifying network bottlenecks and improving user experience.
• Regulatory compliance: Network traffic monitoring and auditing for regulatory adherence.
