Although the information is conceptual, you should learn the names of the protocols. You should also learn what each protocol does. At the time of this writing, you obtain this address from an Internet service provider ISP. If hosts on your network are to participate in the Internet Domain Name System DNSyou must obtain and register a unique domain name.
Each host involved in a communication transaction runs its own implementation of the protocol stack. Physical Network Layer The physical network layer specifies the characteristics of the hardware to be used for the network. For example, it specifies the physical characteristics of the communications media.
It also provides error control and "framing. Internet Layer This layer, also known as the network layer, accepts and delivers packets for the network. IP is responsible for: Packet formatting - IP assembles packets into units known as IP datagrams.
Datagrams are fully described in "Internet Layer". Fragmentation - If a packet is too large for transmission over the network media, IP on the sending host breaks the packet into smaller fragments.
IP on the receiving host then reconstructs the fragments into the original packet. Previous releases of the Solaris operating environment implemented version 4 of the Internet Protocol, which is written IPv4. However, because of the rapid growth of the Internet, it was necessary to create a new Internet Protocol with improved capabilities, such as increased address space.
This new version, known as version 6, is written IPv6. The Solaris operating environment supports both versions, which are described in this book. To avoid confusion when addressing the Internet Protocol, the following convention is used: When the term IPv4 is used in a description, the description applies only to IPv4.
When the term IPv6 is used in a description, the description applies only to IPv6. ARP assists IP in directing datagrams to the appropriate receiving host by mapping Ethernet addresses 48 bits long to known IP addresses 32 bits long.
This type of communication is known as "end-to-end. TCP sends data in a form that appears to be transmitted in a character-by-character fashion, rather than as discreet packets. This transmission consists of a starting point, which opens the connection, the entire transmission in byte order, and an ending point, which closes the connection.
TCP attaches a header onto the transmitted data. This header contains a large number of parameters that help processes on the sending machine connect to peer processes on the receiving machine.
TCP confirms that a packet has reached its destination by establishing an end-to-end connection between sending and receiving hosts. TCP is therefore considered a "reliable, connection-oriented" protocol.
It does not provide any means of verifying that connection was ever achieved between receiving and sending hosts. Because UDP eliminates the processes of establishing and verifying connections, applications that send small amounts of data use it rather than TCP.
Application Layer The application layer defines standard Internet services and network applications that anyone can use. These services work with the transport layer to send and receive data.
There are many applications layer protocols, some of which you probably already use. Some of the protocols include:Introduction to TCP/IP The Ohio State University Columbus, OH Nayna Networks TCP/IP Model TCP/IP Protocols OSI Ref Model. 4 © Raj Jain Layered Packet Format!

This is an 8 bit field. This is an 8 bit field. In Internet Protocol version 6 (IPv6) [ RFC ], this field is called the "Next Header" field. Biography I received the B.S.E.
