How does ping plotter work

Hop hop count A hop count of X equates to having X gateways between the source host and destination host. Router A networking device that routes or forwards data packets from one computer network to another. Server A computer that provides data to other computers. This could be confined to a house, apartment, or office floor but could very well apply to an entire building.

Access can be granted via different links, such as virtual private networks VPNs , wireless networks, cellular networks, or Internet access. The Internet The internet is a global WAN meaning that it can connect with other wide area networks as well as local area networks.

It includes many high-bandwidth data lines that comprise the Internet "backbone" backbones interconnect various pieces of WANs. These lines are connected to major hubs that distribute data to other locations, such as web servers and ISPs Internet Service Providers. It is a global network of connections from millions of devices that facilitates the exchange of information not to be confused with the World Wide Web.

This network utility helps to determine the path that packets take your data through various networks to the destination by exploiting a field in the IP Packet Header called TTL Time-To-Live , which is normally used to prevent routing loops using Layer 3 of the OSI model. What can we determine from the graph below? There's a problem someplace in the route, but we need to determine where Hop 5 doesn't show packet loss, though, so you know that the problem in hop 16 isn't because of hop 4.

This is a huge indication of where the problem lies. Over time a graph is created to the right of the application providing statistics of packet loss and latency for each individual hop between your PC and the data center. From this, the 8x8 Network Engineering team can provide recommendations to resolve the issue.

A complete graph is created showing the results over the duration of the test. To provide the most complete information, we recommend running the test for a minimum of 2 hours or for at least the duration of your business hours, if not 24 hours.

This graph provides the three most important metrics graphed simultaneously: Jitter, Packet Loss, and Latency. The blue "X" is the average ping for a hop. You can manually specify a different IP address or WhoIs server by changing the values at the top of the window shown in Figure D. Another shortcut option allows you to query the WhoIs database for a device somewhere along your ping route. As is the case with the IP address block lookup, you can manually change the query information at the top of the screen to get information for other domains.

In Figure B, you saw a single graph at the bottom of the screen. This initial graph corresponds to the last device along the route.

However, you can add graphs for as many hops as you like. This view Figure E can be useful if you need to watch interactions between more than one hop. By default, PingPlotter displays graphing information on a minute scale. Whether you have very little information or whether you have a whole lot of information, PingPlotter gives you a way to change the graph scale so you can get a look at the information in a way that makes sense for you. When you're troubleshooting a problem, you sometimes need to make note of a particular anomaly so you can check up on it later.

By right-clicking on the graph at the time of a particularly interesting event and choosing Create Comment, you can add a comment to your graph. Take a look at the graphs at the bottom of Figure F. Each graph has a little red triangle pointing to a spot along the timeline. By hovering the mouse over that triangle, you can reveal any added comments. You can stop and start the plotting process at any time for any of your addresses.
