Introduction to TCP/IPand Internet Governance

What is TCP/IP

Transmission Control Protocol / Internet Protocol

TCP/IP refers to an entire suite of networking protocol, developed for use on the Internet.

TCP and IP are certainly two of the most important.

3

TCP/IP Characteristics

TCP/IP provides the services necessary to interconnect computers and to interconnect networks, creating the Internet.

Independent from underlying network topology, physical network hardware, and OS.

Unique IP address Universal connectivity through out the network

TCP/IP Internetworking

5

TCP/IP Networking Software

TCP/IP protocol suites define a set of universal communication service/

Service can be implemented in standardized manner in the networking software, normally bundled in OS.

TCP/IP and Internet

1957 USSR Spunik , USA establish ARPA 1969 ARPA funded ARPANET 1971 Network with 15 nodes 1973 Ethernet (Bob Metcalfe, Ph.D.

Dissertation) 1983 TCP/IP as a core protocol 1983 BSD 4.2 (U. Berkeley ) with TCP/IP

7

TCP/IP Implementations

1983 4.2BSD: first widely available TCP/IP release

1986 4.3BSD: performance improvements 1988 4.3BSD Tahoe: add slow start,

congestion avoidance and fast retransmit 1990 4.3BSD Reno: add TCP header

prediction. SLIP compression, new routing table

1993 4.4BSD: add multicasting

The world wide group of networks combined with TCP/IP

Who control Internet?No single administrative organization IETF determines standards industry also preemptive control standards

ICANN

Formed in October 1998Internationalization of Policy Functions

for DNS and IP Addressing systems and Private Sector (Non-governmental) Management

Internet Corporation for Assigned Names and Numbers

14

What does ICANN do?

Coordinates policies relating to the unique assignment of:

Top Level Domain Names (gTLDs, cTLDs) IP Address Protocol Port and Parameter Numbers

Coordinates the DNS Root Server System- through Root Server System Advisory Committee

Does ICANN regulate/govern?

ICANN coordinates. What ICANN is NOT

Technical Standard-Setting Body Internet Police Force Consumer Protection Agency Competition Authority Legislature or Court

Situation Before ICANN

Most Internet DNS and IP Address coordination functions performed by, or on behalf of, the US government

Defense Advanced Research Projects Agency (DARPA) Information Sciences Institute (ISI) of University of

Southern California Stanford Research Institute (SRI)

National Science Foundation (NSF) IBM, MCI, and Merit AT&T, General Atomics, Network Solutions, Inc.

Need for Change

Globalization of Internet Commercialization of Internet Need for accountability Need for more formalized management structure Dissatisfaction with lack of competition Trademark/domain name conflicts

Status of Transition from USG

25 November, 1998 - ICANN recognized in MoU June, 1999 - Cooperative agreement among ICANN, US Government,

root server operators 10 November, 1999

• ICANN and Network Solutions sign gTLD registry and registrar agreements

• DoC transfers root authority over gTLDs to ICANN 9 February, 2000

• Contract with US Government to complete transfer of IANA functions Year 2000:

ccTLD registry agreements RIR (Regional Internet Registries) agreements
