Internet Protocol Suite
IP Suite commonly known as TCP/IP (stands for Transmission Control Protocol / Internet Protocol) is a set of communication protocols used for the Internet and other similar networks. There are many types of protocol in IP Suite, including TCP and IP. They choose TCP/IP as the name because both TCP and IP was the first two networking protocols defined in this standard.
IP Suite may be viewd as a set of layers. Like many protocol suites, upper layer are logically closer to the user and deal with more abstract data, replying on lower layer protocols to translaate data into forms that can eventually be physically transmitted. From the highest layer; Application Layer, Transport Layer, Internet Layer, and Link Layer.
TCP/IP suite uses encapsulation to provide abstraction of protocols and services. In general, an application (the highest level of IP Suite Model) uses a set of protocols to send its data down the layers, being further encapsulated at each level.
In computer networking, encapsulation is a method of designing modular communication protocols in which logically separate functions in the network are abstracted from their underlying structures by inclusion or information hiding within higher level objects.
| Application | DNS, TFTP, TLS/SSL, FTP, Gopher, HTTP, IMAP, IRC, NNTP, POP3, SIP,
SMTP,SMPP, SNMP, SSH, Telnet, Echo, RTP, PNRP, rlogin, ENRP |
|---|---|
| Routing protocols like BGP and RIP which run over TCP/UDP,
may also be considered part of the Internet Layer. |
|
| Transport | TCP, UDP, DCCP, SCTP, IL, RUDP, RSVP |
| Internet | IP (IPv4, IPv6) ICMP, IGMP, and ICMPv6 |
| OSPF for IPv4 was initially considered IP layer protocol since it
runs per IP-subnet, but has been placed on the Link since RFC 2740. |
|
| Link | ARP, RARP, OSPF (IPv4/IPv6), IS-IS, NDP |
*types of protocol in each respective layer.
p/s: This notes was based from WIKIPEDIA: Internet Protocol Suite. For more information, why don’t you read over there? 
nice topic, its like network OSI details..
if u got time please post for basic OSI layer? its like an advance OSI details for me.. ^_^
connection from Router A to Router B need trunking configuration rite?
how to trunk it??
thank you
I don’t think a connection from A to B requires a trunk. (I’m not really expert in Network, seriously.)
Trunking is required for VLAN (as far as I know). If you know about it, mind to share with me?
