The Packet Slicing feature of the GigaSMART® engine truncates packets while preserving the portion of the packet (the protocol headers) required for network analysis. Packet Slicing can parse variable header packets, starting slicing after a named header (IP, TCP, etc.) with or without VLAN and other tags. Thus, there's no need to rely on a fixed offset to slice packets.
Packet Slicing removes payload that may be irrelevant to network monitoring and security analysis. This reduces tool throughput and disk space while improving performance and data retention. It also removes sensitive data before it is stored, which makes regulatory and privacy compliance easier.
