1.2 DAG 4.3GE Card Product Description
Description The DAG 4.3GE card is a PCI-X bus card designed for cell and packet
capture and generation on Ethernet networks.
Figure
Figure 1-1 shows the DAG 4.3GE PCI-X card.
Figure 1-1. DAG 4.3GE PCI-X Card.
The DAG 4.3GE card collects packet header and payload from Ethernet
networks and is protocol independent. Full packet capture at line rate
allows recording of all header information and/or payload with a high
precision timestamp.
The DAG 4.3GE is capable of transmitting packets at 100% line rate on
both ports while simultaneously receiving packets at 100% line rate on
both ports.
1.3 DAG 4.3GE Card Architecture
Description Serial Ethernet optical network data received by two 1000baseSX optical
interfaces flow into an Ethernet Framer ASIC then immediately into the
Field-Programmable Gate Array [FPGA].
The FPGA contains an Endace DAG Universal Clock Kit
[DUCK]
timestamp engine, packet record processor, and PCI-X interface logic.
Because of component close association, packets or cells are time-stamped
accurately. Time stamped packet records are stored in an external FIFO
memory before transmission to the host.
