2. Packet switching - Wikipedia

   en.wikipedia.org/wiki/Packet_switching

   A simple definition of packet switching is: The routing and transferring of data by means of addressed packets so that a channel is occupied during the transmission of the packet only, and upon completion of the transmission the channel is made available for the transfer of other traffic. [5][6] Packet switching allows delivery of variable bit ...

3. Forwarding information base - Wikipedia

   en.wikipedia.org/wiki/Forwarding_information_base

   Forwarding information base. A forwarding information base (FIB), also known as a forwarding table or MAC table, is most commonly used in network bridging, routing, and similar functions to find the proper output network interface controller to which the input interface should forward a packet. It is a dynamic table that maps MAC addresses to ...

4. Routing - Wikipedia

   en.wikipedia.org/wiki/Routing

   Routing is the process of selecting a path for traffic in a network or between or across multiple networks. Broadly, routing is performed in many types of networks, including circuit-switched networks, such as the public switched telephone network (PSTN), and computer networks, such as the Internet. In packet switching networks, routing is the ...

5. Packet forwarding - Wikipedia

   en.wikipedia.org/wiki/Packet_forwarding

   A broadcast forwarding pattern, typical of bridged Ethernet. The simplest forwarding model‍—‌ unicasting ‍—‌involves a packet being relayed from link to link along a chain leading from the packet's source to its destination. However, other forwarding strategies are commonly used. Broadcasting requires a packet to be duplicated and ...

6. Trivial File Transfer Protocol - Wikipedia

   en.wikipedia.org/wiki/Trivial_File_Transfer_Protocol

   The initiating host A sends an RRQ (read request) or WRQ (write request) packet to host S at port number 69, containing the filename, transfer mode, and optionally any negotiated option under the terms of RFC 2347. S replies with an option ACK if options were used, and an ACK (acknowledgement) packet to WRQ and directly with a DATA packet to RRQ.

7. Automatic Packet Reporting System - Wikipedia

   en.wikipedia.org/wiki/Automatic_Packet_Reporting...

   Automatic Packet Reporting System (APRS) is an amateur radio -based system for real time digital communications of information of immediate value in the local area. [1] Data can include object Global Positioning System (GPS) coordinates, non-directional beacon, weather station telemetry, text messages, announcements, queries, and other telemetry.

8. Deep packet inspection - Wikipedia

   en.wikipedia.org/wiki/Deep_packet_inspection

   v. t. e. Deep packet inspection (DPI) is a type of data processing that inspects in detail the data being sent over a computer network, and may take actions such as alerting, blocking, re-routing, or logging it accordingly. Deep packet inspection is often used for baselining application behavior, analyzing network usage, troubleshooting network ...

9. Acknowledgement (data networks) - Wikipedia

   en.wikipedia.org/wiki/Acknowledgement_(data...

   Acknowledgement (data networks) In data networking, telecommunications, and computer buses, an acknowledgement (ACK) is a signal that is passed between communicating processes, computers, or devices to signify acknowledgment, or receipt of message, as part of a communications protocol. Correspondingly a negative-acknowledgement (NAK or NACK[1 ...
