Protocol Protocol enable network communication from one host through the network to another host. A protocol is a formal description of a set of rules and conventions that govern a particular aspect of how devices on a network communicate. Determine the format, timing, sequencing, and error control in data communication. Without protocols, the computer cannot make or rebuild the stream of incoming bits from another computer into the original format
Protocol
How the physical network is built How computers connect to the network How the data is formatted for transmission How that data is sent How to deal with errors

Peer-to-Peer Communication
Protocol TCP/IP
DoD Model Standard for Military Open standard First Protocol used in Internet 4 layer Encapsulation Data Packet
17
TCP is a connection-oriented protocol Connections Reliable Cirinya :semua paket mendapat tanda terima, paket error maka akan dikirim ulang, setelah sampai paket akan diurut kembali
TCP/IP Model
18
Applications Layer Telnet, FTP, SMTP, TFTP, DNS, SMTP
Transport Layer (host to host) Protocolnya TCP (Transmision Control Protocol) dan UDP (user datagram protocol) TCP berfungsi untuk mengubah satu blok data yang besar menjadi segmen-segmen yang dinomori dan disusun secara berurutan UDP jenis protocol connectionless oriented, dimana penerima tidak menerima tanda terima, namun unggul dalam penggunaan bandwidth
19
Internet Layer Protocolnya : } } } } } }
IP (internet protocol) ARP (address resolution protocol) DHCP (dynamic host control protocol) ICMP (internet control configuration protocol) RARP (Reverse address resolution protocol) BOOTP (Boostrap Protocol)
Network Access layer Protocolnya : ethernet, Token ring dan FDDI

Router User Interface Modes
45
User EXEC mode User EXEC mode : mode ini level paling bawah, logon pertama ke router, digunakan untuk memeriksa statistik dan informasi dasar router. Perintahnya : ping, traceroute, telnet,en, exit,logout, show Router >
Privilege EXEC mode Lapisan lebih tinggi user EXEC mode, mendapatkan informasi lebih detail, melakukan pengujian, debugging, dan manipulasi file Peritah : clock, config, copy, debug, disable,disconnect, exit, erase, ping reload Router> Router>en router#
46
Global Config Mode Lapisan paling tinggi, dpt melakukan konfig secara global, seting acl atau firewall, banner, FR, nama host Perintah : access-list,banner,cdp,configregister,en, exit,exec-timeout, framerelay, hostname,int,login Router# Router#config t Router(config)#
