Network Protocols – Data Communication and Networks

  • ethernet – Provides for transport of information between physical locations on ethernet cable. Data is passed in ethernet packets
  • SLIP – Serial line IP (SLIP), a form of data encapsulation for serial lines.
  • PPP – Point to point protocol (PPP). A form of serial line data encapsulation that is an improvement over SLIP.
  • IP – Internet Protocol (IP). Except for ARP and RARP all protocols’ data packets will be packaged into an IP datapacket. Provides the mechanism to use software to address and manage data packets being sent to computers.
  • ICMP – Internet control message protocol (ICMP) provides management and error reporting to help manage theprocess of sending data between computers.
  • ARP – Address resolution protocol (ARP) enables the packaging of IP data into ethernet packages. It is the system and messaging protocol that is used to find the ethernet (hardware) address from a specific IP number. Without this protocol, the ethernet package could not be generated from the IP package, because the ethernet address could not be determined.
  • TCP – A reliable connection oriented protocol used to control the management of application level services between computers.
  • UDP – An unreliable connection less protocol used to control the management of application level services between computers.
  • DNS – Domain Name Service, allows the network to determine IP addresses from names and vice versa.
  • RARP – Reverse address resolution protocol (RARP) is used to allow a computer without a local permanent data storage media to determine its IP address from its ethernet address.
  • BOOTP – Bootstrap protocol is used to assign an IP address to diskless computers and tell it what server and file to load which will provide it with an operating system.
  • DHCP – Dynamic host configuration protocol (DHCP) is a method of assigning and controlling the IP addresses of computers on a given network. It is a server based service that automatically assigns IP numbers when a computer boots. This way the IP address of a computer does not need to be assigned manually. This makes changing networks easier to manage. DHCP can perform all the functions of BOOTP.
  • IGMP – Internet Group Management Protocol used to support multicasting.
  • SNMP – Simple Network Management Protocol (SNMP). Used to manage all types of network elements based on various data sent and received.
  • RIP – Routing Information Protocol (RIP), used to dynamically update router tables on WANs or the internet.
  • OSPF – Open Shortest Path First (OSPF) dynamic routing protocol.
  • BGP – Border Gateway Protocol (BGP). A dynamic router protocol to communicate between routers on different systems.
  • CIDR – Classless Interdomain Routing (CIDR).
  • FTP – File Transfer Protocol (FTP). Allows file transfer between two computers with login required.
  • TFTP – Trivial File Transfer Protocol (TFTP). Allows file transfer between two computers with no login required. It is limited, and is intended for diskless stations.
  • SMTP – Simple Mail Transfer Protocol (SMTP).
  • NFS – Network File System (NFS). A protocol that allows UNIX and Linux systems remotely mount each other’s file systems.
  • Telnet – A method of opening a user session on a remote host.
  • Ping – A program that uses ICMP to send diagnostic messages to other computers to tell if they are reachable over the network.
  • Rlogin – Remote login between UNIX hosts. This is outdated and is replaced by Telnet.
