Deep Packet Inspection

Deep packet inspection (DPI), also known as complete packet inspection, is used to monitor network traffic at the packet level. Unlike conventional packet filtering, DPI looks beyond just packet headers and examines the actual content of packets passing through a given checkpoint, like an APCON switch or a firewall, to locate, identify, and classify packets of a specific type or those with a certain payload and react accordingly.

Understand your traffic

Since DPI allows IT teams to categorize traffic based not just on data — like origin server IP, destination IP, or ports used— but also things like traffic type, relative or total traffic volume, and actual payload, they can search for non-compliance with protocols and filtering rules, spam, viruses, and malware. Based on inspection results, they can then classify, reroute, or block packets.

This kind of packet inspection can provide immediate insight into network threats or slowdowns and determine whether reduced throughput is caused by the network or an application. For instance, with DPI, IT teams can identify harmful, excess, or unnecessary traffic that may need to be rerouted, filtered, or eliminated entirely.

Optimize and secure your traffic

Teams can also isolate and analyze traffic flowing over a specific network link or to/from specific servers or applications, allowing for more informed capacity management. Using various techniques including pattern matching, deep protocol dissection, semantic and conversational awareness, behavioral analysis, and flow registration, APCON deep packet inspection allows network operators to pinpoint the traffic in question, revealing malicious traffic, performance bottlenecks, failing applications, or excess levels of non-business traffic. Deep traffic awareness can be acted upon to analyze user behavior, prioritize business-critical traffic, or stop data leaks. Identifying and blocking the source IP of malicious traffic, for example, is very effective against buffer overflow and distributed denial-of-service (DDoS) attacks.
