EDM 01-17 DAG 7.1S Card User Guide
Chapter 1:
Introduction
Overview Endace DAG 7.1S 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 7.1S is a Network Monitoring Interface card specifically designed
to provide high efficiency monitoring and transmission of ATM or POS
traffic with precision timestamping capability on 4 x STM-1 or 2 x STM-2
interfaces
