  1. Network monitoring on 10GbE Y. Kodama ITRI (Information Technology Research Institute) AIST (National Institute of Advanced Industrial Science and Technology) NEGST2008 @ Toulouse 2008/6/24

  2. ITRI, AIST • GTRC (Grid Technology Research Center) was finished March 2008. • Research activities of GTRC were merged to ITRI (Information Technology Research Institute), and continues research of Grid middleware and infrastructure. • The director of ITRI is Sekiguchi who was the director of GTRC. NEGST2008 @ Toulouse 2008/6/24

  3. GtrcNET-10 • GtrcNET is a fully programmable hardware network box. • GtrcNET-1, which has 4 ports of GbE, was produced in 2003. • GtrcNET-10, which has 3 ports of 10GbE, was produced in 2005. NEGST2008 @ Toulouse 2008/6/24

  4. SO-DIMM DDR333 10GbE XENPAK. SO-DIMM DDR333 10GbE XENPAK SO-DIMM DDR333 10GbE XENPAK Architecture of GtrcNET-10p3 1GBytes 4bit x 3.125GHz FPGA (XC2VP100) 64bit x 162MHz x 2 10GbE MAC 10GbE MAC 64bit x 156.25MHz 10GbE MAC System ACE/CF USB2.0 MICTOR GPS NEGST2008 @ Toulouse 2008/6/24

  5. Functions • Delay emulation: Up to 800 ms delay without packet losses by 1 us step. • Random frame loss: The rate of frame losses is controlled by 2-31. • Output bandwidth Control: pacing (154Mbps-10Gbps) or shaping / policing by token bucket (1Mbps-10Gbps) • Buffer size control: It controls the buffer size storing input frames up to 1 GByte by 1 KByte step. • Frame generation: It generates UDP frames with several parameters, such as frame length, bandwidth, burstiness, VLAN tag, etc. • Bandwidth measurement: It measures all of input and output bandwidth every 10ms. Two of ports are measured more precisely every 100 us. • Per-stream bandwidth measurement:using stream ID specified by any 8 bit field in header, per-stream bandwidth is measured every 1 ms. • Frame capture:Itcaptures frames in 1 GBytes of memory. It is available to capture any combination of all frames or filtered frames, and whole fields or selected header fields. • Capture Forwarding:Captured header fields are transmitted by frames. The number of captured data in a frame is controlled. Destinations are distributed up to 16 nodes. NEGST2008 @ Toulouse 2008/6/24
