single-pass, per-packet basis. Reassembly free virus scanning functionality of the SonicWALL 
GAV engine is inherited from the Deep Packet Inspection engine, which is capable of scanning 
streams without ever buffering any of the bytes within the stream.

Building on SonicWALL's reassembly-free architecture, GAV has the ability to inspect multiple 
application protocols, as well as generic TCP streams, and compressed traffic. SonicWALL 
GAV protocol inspection is based on high performance state machines which are specific to 
each supported protocol. SonicWALL GAV delivers protection by inspecting over the most 
common protocols used in today's networked environments, including SMTP, POP3, IMAP, 
HTTP, FTP, NetBIOS, instant messaging and peer-to-peer applications and dozens of other 
stream-based protocols. This closes potential backdoors that can be used to compromise the 
network while also improving employee productivity and conserving Internet bandwidth.
