Overview

The Deeper Application Recognition (DAR) feature identifies packets of dynamic protocols like BitTorrent, HTTP, FTP, and RTP by examining Layer 4 to Layer 7 content other than the IP header. The feature helps service providers and businesses limit aggressive bandwidth use by applications like BitTorrent to ensure fairness and network performance.

BitTorrent is a P2P file sharing communications protocol, which enables personal computers to directly exchange data or services. P2P has been widely used for content (such as audio and video) file sharing. It represents a large amount of bandwidth on the Internet.

DAR can limit, block, or manipulate identified application traffic depending on your configuration.

The DAR feature is applicable to IP packets.
