Accurate classification of traffic flows is essential for network administrators to enable network tasks such as quality of service (QoS), detect threats, and restrict forbidden applications. Most tools utilize well-known signatures for network traffic classification. In recent years, more applications have begun encrypting traffic to protect subscriber content. With encrypted traffic on the rise, the amount of traffic that can be recognized by inspection of IANA-assigned port numbers and well-known application signatures has reduced drastically.
The 128T Session Smart™ Router operates on the principle of applying intelligent heuristics to detect network traffic without decryption. Read this feature brief to better understand how the the 128T Session Smart Routers can identify traffic in all routers, not only at the edges. And how they can also share previously detected traffic information among themselves for quick detection.
