White Paper: Successful High-Precision QoS Measurement In Widely Deployed 10-Gbit/s Networks Based On General-Purpose Personal Computers
By Kenji Shimizu, Katsuhiro Sebayashi, and Mitsuru Maruyama, NTT Science and Core Technology Laboratory Group
NTT Laboratories has developed a 10-Gbit/s PCI (peripheral component interconnect) network interface card (NIC) with network measurement extensions (measurement NIC). It works both as a normal NIC for a 10-Gbit/s network and as a measurement NIC. Its extensions enable precise measurements of the network status and quality of service (QoS). It will let us develop a reliable network measurement system based on inexpensive general-purpose personal computers (PCs). This article describes techniques for building 10-Gbit/s wire-rate precise network measurement systems that can measure the quality of service (QoS) of high-speed networks precisely and quickly, even with non-sampling measurements.
