THE FATHER OF THE INTERNET

Vinton Cerf & Bob Kahn “A protocol for packet network Interconnection”, IEEE Journal Com, 1974

Gateway notion is introduced Interconnection of Packet network via Gateway Flow control, sequencing, failures with TCP Communication via Host’s IP address TCP: Transmission Control Protocol IP: Internet Protocol (IP packet, IP header...)

TCP/IP is the heart of the Internet !

THE DESIGN PHILOSOPHY OF TODAY’S INTERNET • Packet switching • No connection setup • Forwarding packet regarding the host address

• TCP/IP suite • TCP for flow control, reliable delivery • IP for forwarding packet based on Host’s IP address • Multiple layer (Application, Transport, Network, Host…)

• Host-centric approach • End-to-end communication between Hosts • HOST as the center of all consideration

Wired networks & End-to-end communication !

WHAT HAS CHANGED • Wireless networks, Mobile devices • Mobility, Multi-homing,

• Online video entertainment • multiparty communication

• Cloud computing and services • Focusing on Sharing Information and Services

WHAT HAS CHANGED • Wireless networks, Mobile devices • Mobility, Multi-homing,

• Online video entertainment • One-to-many communication

• Cloud computing and services • Focusing on Sharing Information and Services

• Peer to Peer applications • Many-to-many communications

WHAT HAS CHANGED • Wireless networks, Mobile devices • Mobility, Multi-homing,

• Online video entertainment • Multimedia communication, multiparty communication

• Cloud computing and services • Focusing on Sharing Information and Services

• Peer to Peer applications • Many-to-many communications

• Reviewing Internet traffic • P2P, Web (is not the End-to-end communication)

WHAT HAS CHANGED

Communication Many-to-many via Information’s identifier

• Communication End-to-End via Host’s IP address

Change communication style • Internet is redesigned !

INFORMATION CENTRIC NETWORKS • Shift from connecting end nodes to connecting users to content • One to many nodes communication (Multiparty) through replication, caching • Interaction model via Publish/Subscribe paradigm • Concentrate on the Content, Information rather than Host address • Information-centric approach • INFORMATION as the center of all consideration

INTERNET IN VIETNAM • Hot news: Established Vietnam Internet Union (VIA) 9/10/2010 by Ministry of Information and Communications • 1/12 as usual Internet Vietnam Day (13 years ago) • Currently 66 partners (VDC, Netnam, FPT Telecom, …) • To achieve the No.1 of using Internet in Asian • VNTelecom Webinar is one of good demonstration of innovative conference, the powerful of Internet • From three countries( France, Japan, Vietnam), the presentation via Webinar using Internet connection. • People can join from any where, any countries (just need an Internet connection)

INTERNET IN VIETNAM • • • • • •

Internet come to Mobile: 3GPP, LTE 4G (Testing) Surround every region, Come to all families 100% universities have internet access Internet to Island, Rural area To obtain over 70% Vietnam’s population in 2020 Internet is the Key of Information Society, Society Evolution • Work business, education, entertainment, social life • E-Government, E-Commerce • …
