Apa itu Internet

• Jaringan dari jaringan hubungan dari jutaan
  device komputer host, end-system
• PC, servers
• PDA
• Aplikasi jaringan
• Communication link
• Fiber (FDDI), copper (UTP, cable model ethernet),
  radio (Wifl), satelit
• Router mengirim paket (chunks) (dari data)
  melalui jaringan

22
Apa itu Internet (lanjutan)

• Protokol control sending, receiving of messages
• Cth TCP, IP, HTTP, FTP, PPP
• Internet "network of networks"
• loosely hierarchical
• public Internet versus private intranet
• Standarisasi Internet
• RFC Request for comments
• IETF Internet Engineering Task Force

23
Struktur Network

• network edge applications and hosts
• network core
• routers
• network of networks
• access networks, physical media communication
  links

24
The Network Edge

• end system (host)
• run application program
• e.g., WWW, email
• at "edge of network"
• client/server model
• client host requests, receives service from
  server
• e.g., WWW client (browser)/ server email
  client/server
• peer-peer model
• host interaction symmetric
• e.g. Gnutella, KaZaA

Protokol

• Berisi suatu set penataan aturan pengartian dan
  format frame, packet, atau message yang saling
  bertukaran antara peer entities dalam suatu
  layer.
• Protokol digunakan untuk berkomunikasi antara
  entity pada sistem.
• Entity menggunakan protokol untuk
  mengimplementasikan service definition.
• Kunci elemen protokol
• Syntax Termasuk format data waktu dan level
  sinyal
• Semantic Termasuk informasi control and error
  handling.

Proses Rekayasa Protokol

• Need for protocol engineering
• Many protocols if not properly designed and
  implemented as per the requirements, leads to
  improper behavior of network and system may jam
  the networks.
• Hence it is required to, engineer the protocols
  for their correctness reliability, optimized
  performance, reusability, and code optimization
• Deals with application of formal techniques and
  software engineering methodologies to protocol
  design and implementation
