Packet Tracer is a cross-platform visual simulation tool designed by Cisco Systems that allows users to create network topologies and imitate modern computer networks. The software allows users to simulate the configuration of Cisco routers and switches using a simulated command line interface.
The command reports the round-trip times of the packets received from each successive host (remote node) along the route to a destination. The sum of the mean times in each hop is a measure of the total time spent to establish the connection. The command aborts if all (usually three) sent packets are lost more than twice.
The trace command is actually a script which runs the program tracedaemon with some common options. It is possible to run tracedaemon directly and in that case, the user can use a number of command-line options to control the data which is collected. For the complete list of options supported by tracedaemon, see the online manual page for ...

Local Area Transport (LAT) [1] [2] is a non-routable (data link layer) networking technology developed by Digital Equipment Corporation [3] to provide connection between the DECserver terminal servers and Digital's VAX and Alpha and MIPS host computers via Ethernet, giving communication between those hosts and serial devices such as video terminals and printers.
The Serial Line Internet Protocol (SLIP) [1] [2] is an encapsulation of the Internet Protocol [a] designed to work over serial ports and router connections. It is documented in RFC 1055 . On personal computers, SLIP has largely been replaced by the Point-to-Point Protocol (PPP), which is better engineered, has more features, and does not ...
Wireshark is very similar to tcpdump, but has a graphical front-end and integrated sorting and filtering options.. Wireshark lets the user put network interface controllers into promiscuous mode (if supported by the network interface controller), so they can see all the traffic visible on that interface including unicast traffic not sent to that network interface controller's MAC address.
The advantages of PathPing over ping and traceroute are that each node is pinged as the result of a single command, and that the behavior of nodes is studied over an extended time period, rather than the default ping sample of four messages or default traceroute single route trace. The disadvantage is that it takes a total of 25 seconds per hop ...
