The purpose of my work

• To find some Network benchmark Software which can
  provide the information of Network and do some
  test on these system
• max and real-time speed of bit/second,
• max and real-time speed of package/second,
• CPU time for network
• TCP replay function to perform testing

4
What have been found in internet?

• Netperf
• NetPIPE
• AnalogX Netstt Live
• Any Speed 1.3
• Ativa Dun Meter 2.2
• ICB 2000 V4.0.7
• Qchecj1.3
• Stat n Perf 1.1

5
What may suitable for us?

• Observe
• NetPIPE

6
Netpipe

• NetPIPE is a protocol independent performance
  tool that encapsulates the best of ttcp and
  netperf and visually represents the network
  performance under a variety of conditions.
• By taking the end-to-end application view of a
  network, NetPIPE clearly shows the overhead
  associated with different protocol layers.
• NetPIPE runs on the UNIX Operating System

7
The Function of Netpipe

• Netpipe answers such questions as
• how soon will a given data block of size k
  arrive at its destination?
• Which network and protocol will transmit size k
  blocks the fastest?
• What is a given network's effective maximum
  throughput and saturation level?
• Does there exist a block size k for which the
  throughput is maximized? How much communication
  overhead is due to the network communication
  protocol layer(s)?
• How quickly will a small (lt 1 kbyte) control
  message arrive,
• Which network and protocol are best for this
  purpose?

8
What information provide by the test result

• By testing the Netpipe in our lab, it gave the
  result of
• time to transfer the block,
• bits per second,
• bits in block,
• bytes in block,
• and variance.
• These columns may be graphed to represent and
  compare the network's performance.

Observe

• Observe is a network monitor and protocol
  analyser for Ethernet, Token Ring and FDDI.
• Observer is 32-bit Microsoft Windows-based
  network monitor and LAN troubleshooting tool.
• Observer can monitor single-segment LANs and
  multi-segment LANs and WANs, with the addition of
  Probes.

11
The function of Observe

• Monitor and graph real-time bandwidth
  utilization, save historical data
• Use the Efficiency History mode to baseline your
  LAN
• Collect Network Trending using advanced sampling
  for days, weeks, or months. Graph, chart or
  create comparative reports with results
• Capture, view, and decode LAN traffic in real
  time. Decode TCP/IP, IPX/SPX, NetBIOS/NetBEUI,
• Collect statistics by user, packet size, or
  protocol
• Traffic generator and packet buffer replay for
  stress testing, problem duplication
• Network activity display shows at a glance
  critical performance information
