Solutions: Qcheck - Network Performance Measurement

Qcheck - Network Performance Measurement

What's good-looking, powerful, improves your quality of life, and is FREE?

Qcheck, the network troubleshooting utility from Ixia, slices, dices, and checks network response time, throughput, and streaming performance. It even runs anywhere-to-anywhere traceroute!

How Qcheck Works / Start using Qcheck:

Install Qcheck on the computer you'll use to run the Qcheck console. Qcheck runs on any computer running Windows 2000, NT or XP.

Install an Ixia Performance Endpoint (or Qcheck itself, which has the endpoint built in) on any other computers. (You can download Performance Endpoint software free from Ixia!)

That's it! Based on the parameters you select, the Qcheck console will instruct any two endpoints to run a test and return the results to you at the Qcheck console.

• For a response time test, Qcheck returns the minimum, maximum and average number of seconds it took to complete a transaction.
• For a throughput test, Qcheck returns the amount of data per second that was successfully sent between the two endpoints.
• For a streaming test, Qcheck returns the rate at which the streaming data was received by the second endpoint and the amount of packet loss that occurred.
• For a traceroute test, Qcheck returns the number of hops, average hop latency, and the address and names of the host at each hop.

Qcheck vs. Ping	Qcheck	Ping
Tests the response time of traffic on IP networks.
Emulates real application flows across the network to test connectivity and performance.
Tests network throughput.
Tests whether a network can support multimedia traffic.
Tests a network link using the application flows generated by streaming multimedia applications.
Determines at what rate streaming traffic is received and how much packet loss occurs.
Tests the connectivity between your own computer and another computer.
Supports a variety of protocols and can test network performance using TCP, UDP, IPX, and SPX networks.
Shows a workstation's physical memory, operating system levels and CPU utilization.
Runs traceroute between any two workstations on your network, regardless of their locations.

Qcheck and Traceroute

Qcheck's anywhere-to-anywhere traceroute function sets you free! You can now originate a traceroute from any user's workstation on the network that is running a Performance Endpoint. Run anywhere-to-anywhere traceroute from our most popular Performance Endpoints to any other TCP/IP connection. The receiving end in a traceroute test doesn't even need to have endpoint software installed!

Setting up a traceroute is easy:

• Press the Traceroute button and select a protocol (TCP OR UDP)
• Identify the IP addresses of the two endpoints you're targeting (Endpoint 1 must be running a Performance Endpoint)
• Press the Run button
• Qcheck runs the traceroute and reports results, the sequence of hops, the hop latency in ms, and the name of each hop location.

Your Problem	The Qcheck Solution
Someone in accounting calls the Help Desk saying he can't access the database server.	A Qcheck response time test determines if this is a network connectivity problem or not. Qcheck can also determine if this is a problem being experienced by one user, one department, or many employees.
I've got a lot of remote employees connected to my network by 56 Kbps dial-up modems. I wonder what kind of throughput they see.	A Qcheck throughput test indicates how quickly a computer can transmit data across any network. And, from your desk, you can drive Qcheck tests between any two computers on your network.
The reception from the company's videoconferencing system is lousy.	A Qcheck streaming test evaluates the network's ability to support multimedia traffic, letting you know the rate at which traffic is received and how many packets get lost along the way.
You've detected a slow connection between New York & San Francisco but you're in Houston.  How do you isolate the problem?	A Qcheck on-demand traceroute initiates a traceroute test between any two workstations on your network, regardless of their location.
