The maximum size of a data packet on an Ethernet is about fifteen Packets are normally quite smaller, as the network hardware can be a limitingįactor. The maximum size of a TCP/IP packet is approximately 64 KB. Transmit is collected into packets (it cannot be sentĪll at once). The data link and physical layers represent the physical networkĪlmost all hardware protocols work on a packet-oriented basis. The special functions of each layer are mostly implicit in theirĭescription. The uppermost layer, however, is almostĪ complete abstraction from the hardware. The diagram provides one or two examples for each layer. Is supported by the underlying hardware-dependent protocol, such as Ethernet.įigure 19.1: Simplified Layer Model for TCP/IP # Guarantees, to a certain extent, security of the data transfer. On top of IP, TCP (transmission control protocol) The actual network layer is the insecure data transfer via Internet Group Management Protocol: This protocol controls machineĪs shown in Figure 19.1, “Simplified Layer Model for TCP/IP”, data exchange takes place inĭifferent layers. In addition, it provides a special echo mode that can be viewed The end user, but a special control protocol that issues error reports andĬan control the behavior of machines participating in TCP/IP data Internet Control Message Protocol: This is not a protocol for It features a smaller latency period than TCP. UDP is suitable for record-oriented applications. Order in which the data arrives at the recipient is not guaranteed andĭata loss is possible. Transmit is sent in the form of packets generated by the application. User Datagram Protocol: a connectionless, insecure protocol. Implemented wherever the data sequence matters. TCP determines whetherĪny data has been lost or jumbled during the transmission. Original data stream format it was initially sent.
The dataĪrrives at the respective application on the destination host in the Theĭata to transmit is first sent by the application as a stream of data andĬonverted into the appropriate format by the operating system. Transmission Control Protocol: a connection-oriented secure protocol. Several Protocols in the TCP/IP Protocol Family # TCP The operating system and its applications.

Single network protocol, but a family of network protocols that offer various
Linux and other Unix operating systems use the TCP/IP protocol.
