  2. Packet Tracer - Wikipedia

    en.wikipedia.org/wiki/Packet_Tracer

    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.

  3. Address Resolution Protocol - Wikipedia

    en.wikipedia.org/wiki/Address_Resolution_Protocol

    Computer 1 has a packet to send to Computer 2. Through DNS, it determines that Computer 2 has the IP address 192.168.0.55. To send the message, it also requires Computer 2 ' s MAC address. First, Computer 1 uses a cached ARP table to look up 192.168.0.55 for any existing records of Computer 2's MAC address (00:EB:24:B2:05:AC).

  4. traceroute - Wikipedia

    en.wikipedia.org/wiki/Traceroute

    On Unix-like operating systems, traceroute sends, by default, a sequence of User Datagram Protocol (UDP) packets, with destination port numbers ranging from 33434 to 33534; the implementations of traceroute shipped with Linux, [5] FreeBSD, [6] NetBSD, [7] OpenBSD, [8] DragonFly BSD, [9] and macOS include an option to use ICMP Echo Request ...

  5. EtherType - Wikipedia

    en.wikipedia.org/wiki/EtherType

    With the advent of the IEEE 802 suite of standards, a Subnetwork Access Protocol (SNAP) header combined with an IEEE 802.2 LLC header is used to transmit the EtherType of a payload for IEEE 802 networks other than Ethernet, as well as for non-IEEE networks that use the IEEE 802.2 LLC header, such as FDDI. However, for Ethernet, Ethernet II ...

  8. Packet processing - Wikipedia

    en.wikipedia.org/wiki/Packet_Processing

    In digital communications networks, packet processing refers to the wide variety of algorithms that are applied to a packet of data or information as it moves through the various network elements of a communications network. With the increased performance of network interfaces, there is a corresponding need for faster packet processing. [1]

  9. Packet analyzer - Wikipedia

    en.wikipedia.org/wiki/Packet_analyzer

    Packet capture is the process of intercepting and logging traffic. As data streams flow across the network, the analyzer captures each packet and, if needed, decodes the packet's raw data, showing the values of various fields in the packet, and analyzes its content according to the appropriate RFC or other specifications.
