EDM 01-18 DAG 4.5G2/G4/GF Card User Guide
Chapter 1:
Introduction
Overview
Note: Unless specifically stated otherwise, throughout this User Guide
“ DAG 4.5 card ” refers to the DAG 4.5G2/G4/and GF cards.
The Endace DAG 4.5 card provides the means to transfer data at the full
speed of the network into the memory of the host PC, with zero packet loss
guaranteed in even worst-case conditions. Further, unlike a NIC, Endace
products actively manage the movement of network data into memory
without consuming any of the host PC's resources. The full attention of the
CPU remains focused on the analysis of incoming data without a constant
stream of interruptions as new packets arrive from the network. For a busy
network link, this feature has a turbo-charging effect similar to that of adding
a second CPU to the system.
The DAG 4.5 card provides independent two or four port Ethernet network
monitoring at Gigabit speeds and supports header only or variable length
capture. It is capable of transmitting and receiving on each channel
simultaneously allowing a single card to operate inline, monitoring and
transmitting in both directions on a full duplex link.
