You can use the Test TCP utility (TTCP) to measure TCP throughput through an IP path. In order to use it, start the receiver on one side of the path, then start the transmitter on the other side. The transmitting side sends a specified number of TCP packets to the receiving side. At the end of the test, the two sides display the number of bytes transmitted and the time elapsed for the packets to pass from one end to the other.

Network Performance Test Tool Available. 0; 0; NTttcp (Windows port of Berkley's TTCP winsock based test tool) has officially gone live. Available downloads include the TTCP Guide for Understanding and Implementing Defense Experimentation (GUIDEx) and the TTCP Roster forms. TTCP Technical Documents: This page contains TTCP technical documents of broad interest. TTCP Groups: The tasks of TTCP are carried out within the 10 Groups described on this page.

You can then use these figures to calculate the actual throughput on the link. For general information on TTCP, refer to. The TTCP utility can be effective in determining the actual bit rate of a particular WAN or modem connection. However, you can also use this feature to test the connection speed between any two devices with IP connectivity between them. For more information on document conventions, see the. Readers of this document should be knowledgeable of the following: • TTCP requires Cisco IOS ® Software Version 11.2 or higher and Feature Sets IP Plus (is- images) or Service Provider (p- images).

Note: The ttcp command is a hidden, unsupported, privileged mode command. As such, its availability may vary from one Cisco IOS software release to another, such that it might not exist in some releases. Some platforms, for instance, require the Cisco IOS Enterprise feature set in order to perform this activity. This document is not restricted to specific software and hardware versions. • Ensure that there is IP connectivity between the two devices involved in the test.

• Download and install the TTCP software for non-IOS clients, if necessary. In the example shown below, we try to determine the connection speed of a modem connection between a Microsoft Windows PC and an AS5300 Access Server.

Even though many of the topics and explanations that are included here are specific to modem connections, the TTCP utility can be used between any two devices. Use the show modem operational-status command (for a modem link) to check the connection parameters. For other LAN or WAN scenarios, this step is not necessary. Customer-dialin-sj>show modem operational-status 1/51 Parameter #1 Connect Protocol: LAP-M Parameter #2 Compression: None.!--- Output omitted. Parameter #8 Connected Standard: V.90 Parameter #9 TX,RX Bit Rate: 0 This edited output shows that the client is connected in V.90 at a 45333 bps downlink rate and a 24000 BPS uplink rate. Data compression is disabled on the client modem. Epson L100 Waste Ink Pad Resetter L210 on this page.

Since the TTCP test pattern is highly compressible, any data compression would skew our measure of true modem link throughput. • Start the ttcpw program on the PC (in a DOS window), running as a receiver. Refer to the Readme file provided with the windows TTCP software for the appropriate syntax. C: PROGRA~1 TTCPW>El Jardin De Al Lado Pdf Printer. Download Game Gameloft Spongebob Untuk Hp Nokia 320 Kali 240 there. ttcpw -r -s ttcp-r: buflen=8192, nbuf=2048, align=16384/0, port=5001 tcp ttcp-r: socket • Launch the TTCP sender (transmitter) on the AS5300. Leave most settings at the default, except for the number of buffers to transmit. The default number of buffers is 2048, with which the TTCP test would take a long time to complete.

By reducing the number of buffers, we are able to finish the test in a reasonable timeframe. In the example shown below, we try to determine the connection speed of a modem connection between a Microsoft Windows PC and an AS5300 Access Server. Even though many of the topics and explanations that are included here are specific to modem connections, the TTCP utility can be used between any two devices. Note: Try to get a snapshot of the modem (port) operational-status, as described above, just before you begin the TTCP test.
