PCAP Express Delivers Simple Path to 10Gigabit Monitoring

nPulse Networks demonstrates 10Gig Sensor at Interop New York

CHARLOTTESVILLE, VA, USA –  September 26th, 2008 – nPulse Network Systems LLC, a
leading OEM designer of powerful network sensors for monitoring and security applications, has
announced PCAP Express 10G, its latest hardware-accelerated implementation of the popular
PCAP API. The product extends the functionality of nPulse’s PCAP Express technology up to
line-rate 10Gbps monitoring and packet capture.

By transparently applying the power of hardware-acceleration to packet capture, time-stamping,
measurement, filtering and multi-CPU load-balancing, PCAP Express 10G enables easy scaling
of libpcap-based applications such as Wireshark, tcpdump or Snort, to 10Gbps performance, with
standard, cost-effective server hardware.  Software developers seeking higher performance can
quickly move their existing development investment to a completely new level of performance,
opening up entirely new markets and opportunities.
 
Working with its technology partner, Napatech Inc, nPulse demonstrated a 10Gbps packet
capture sensor using tcpdump at last week’s Interop show in New York.  Porting of the tcpdump
application to PCAP Express, and configuration for 10Gbps performance on a standard server
appliance, took less than 10 minutes of effort.  No source code modification was required.  With a
simple recompile using the PCAP Express 10G library in lieu of the standard PCAP library,
tcpdump was capturing traffic at full 10Gbps line rate.  The technology is readily applicable to
other PCAP-based applications in monitoring, capture and storage, and network security.
 
Chad Keefer, networking and security author, industry blogger and consultant with the Minor
Group said, “10Gig technology is proliferating as network traffic continues to grow.  The whole
market needs a quick way to take the familiar tools we already use for gigabit networks, and
power them up for 10Gig.  nPulse’s PCAP Express now makes that a simple proposition.”
 
PCAP Express 10G is available for the Linux and FreeBSD operating systems.  The technology is
embedded in all of nPulse’s sensor products, including the reference designs at
www.npulsenetworks.com and the custom solutions nPulse develops  for its OEM and channel partners. For more about PCAP Express, visit www.pcapexpresss.com.
