(Gawkwire.com) Napatech today launched two new important product features sets to address Traffic Generation and Capture & Replay applications. The Traffic Generation feature set addresses Ethernet full line-rate traffic generation applications, while the Capture & Replay feature set addresses Capture & Replay applications. The introduction of the Traffic Generation and Capture & Replay feature sets coincides with the announcement of Napatech’s new NT20E2 2×10 Gbps PCI-Express Gen 2 In-line and Capture network adapters.
 
“Napatech has identified a need for network adapters focused on Traffic Generation and Capture & Replay applications. While many of the features provided by our existing In-line family can be used in these markets, the needs are slightly different demanding different feature focus and performance” said Erik Norup, President of Napatech Inc. “For example, in in-line applications, latency is extremely important, but not an issue in traffic generation. Similarly, in In-line there is a need to receive and transmit at the same time, while in capture & replay, it is typical that capturing data and replaying data are two separate activities that need not coincide.”
 
The Traffic Generation and Capture & Replay feature sets are supported by the current 4-port 1G and 2-port 10G Napatech products as well as the new NT20E2 2x10Gbps PCI-Express Gen 2 network adapters.
 
Key features for Traffic Generation are:
• Full line-rate 20 Gbps Ethernet traffic generation
• 10ns precision time-stamping of transmitted packets
• Transmit of packets according to individual packet time stamps
• Ethernet, TCP and UDP checksum generation
• Configurable Inter-Frame Gap (IFG)
 
Generated traffic can be application-generated traffic or traffic from a file.
 
Key features for Capture & Replay are:
• Full throughput 10 Gbps capture and analysis per port (max 20 Gbps)
• Full line-rate 10 Gbps replay per port (max 20 Gbps)
• Full capture feature set (similar to Napatech Capture adapters)
• 10ns precision time-stamping on received and transmitted packets
• Replay of packets according to individual packet time stamps
• Hardware time synchronization based on GPS, IEEE1588v2 or CDMA
• Ethernet, TCP and UDP checksum verification and generation
• Configurable Inter-Frame Gap (IFG)
 
The Napatech adapter acceleration features enable on the fly intelligent indexing of received frames for fast data retrieval from storage.
