  • The Time Has Come for Greater Precision

    Time-stamping and time synchronization, once the domains of specialists, is now required knowledge for developers of high performance network monitoring and analysis appliances. In this white paper, we provide an introduction to the key fundamentals of time-stamping and time synchronization with a review of technology choices and testing scenarios. Most importantly, the white paper will show that nanosecond time-stamping and time synchronization is now essential for accuracy and precision especially as we move to 40 and 100 Gbps networks.

  • The Time Has Come for Greater Precision
  • Building Intelligent Mobile Data Services Using Deep Packet Inspection

    The introduction of mobile data services has proven to be a great success. Perhaps too great! The subsequent pressure on mobile networks is placing mobile carriers in the same dilemma that fixed-line carriers have already experienced; namely the “revenue gap” or “scissor effect” where traffic and network costs grow faster than revenue. By building more intelligence into the network, it is possible to address this dilemma by offering user friendly services with more intelligent pricing models that are user rather than network focused. Deep Packet Inspection is a key technology in making this a reality.

  • Building Intelligent Mobile Data Services Using Deep Packet Inspection
  • Consolidating Multiple Network Appliances

    Space and power are major concerns for enterprises and carriers. There is therefore focus on consolidating the number of physical servers in data centers. Application server consolidation is already taking place via virtualization, but what about the various network appliances used to monitor, analyze, measure, secure and optimize IP networks? These are typically stand-alone devices installed at critical points in the network. How can weconsolidate these appliances into fewer servers?

  • Consolidating Multiple Network Appliances
  • Traffic Generation for the Mainstream Ethernet Market

    This white paper provides a new vision for test and measurement equipment vendors: Make sure that every engineer who needs a test and measurement system can get one! The availability of commercial off-the-shelf hardware and software now makes it possible to build affordable test and measurement systems that can help test and measurement equipment vendors to broaden their market to include development engineers who are normally deprived test resources due to cost. To take advantage of this opportunity, test and measurement equipment vendors need to re-think their product development strategy for the mainstream market.

    By combining the latest generation of standard PC servers  with Intelligent Real-time Network Analysis adapters, OEM appliance manufacturers can reduce cost, risk and time-to-market, while also improving the performance of 1 Gbps and 10 Gbps network security appliances.
  • High Performance Network Security Appliances
  • A Guide to Building High Performance Capture and Replay Appliances

    Find out how the latest generation of standard PC servers combined with Intelligent Real-time Network Analysis adapters can be used to build high-performance Capture and Replay appliance for 1 Gbps and 10 Gbps networks.
    Standard PC servers now provide the processing power and efficient memory architecture to ensure high-performing application software capable of recording and replaying 10 Gbps data at line-speed. Napatech intelligent Real-time Network Analysis adapters ensure that data can be captured and transmitted in real-time at 10 Gbps line-rate, while also providing intelligent features that help achieve the 10 Gbps recording and data retrieval necessary for high performance capture and replay applications.

  • Scaling Policy Enforcement and Deep Packet Inspection

    The growth in mobile data networks provides a lucrative opportunity for vendors of Deep Packet Inspection and Policy Enforcement systems. However, in order to take advantage of this opportunity, vendors need to ensure that their solutions can scale to keep up with the projected doubling of mobile data traffic each year. By basing development on Deep Packet Capture technology and standard PC servers, it is possible to scale Deep Packet Inspection systems and Policy Servers to meet the challenge. In addition, it allows vendors to focus on the software development of smarter service discovery algorithms, correlation and more user friendly presentation rather than hardware development.
