The Defense Advanced Research Projects
Agency (DARPA) Requirement



In the late 1960s, DARPA noticed the following trends:
- Rapid proliferation of computers in military communications
- Deployment of multivendor equipment in communication
networks
The U.S. Department of Defense (DoD) mandated a common set
of protocols
- Advantages are
-- Procurement simplification
-- Competition
-- Interoperability
-- Vendor productivity and efficiency
As a result of DoD efforts, the ARPAnet was formed, which later
evolved into the Internet
The Internet community


Earlier Internet community consisted of
- Universities
-- Stanford, UCLA, Massachusetts Institute of Technology (MIT)
-- UCSB
-- University of Utah, University of Hawaii
- Research organizations
-- SRI International, Rand Corporation
-- The Institute of Advanced Computation
-- Bolt, Beranek, and Newman (BBN)
Current Internet Community includes
-
All major universities
Research organizations
Corporations
Individual users

Proprietary Networks

Early commercial computer network
- Proprientary solutions
-- Examples: IBM’s SNA, DEC’s DECnet
- Locked users to vendor platform

Commercial Uses of TCP/IP
Driving Force Behind TCP/IP Support


Currently, the driving force behind TCP/IP support is
- Growth in network-management tools
- Promise of interoperability
- Commercialization of the Internet
Most widely implemented network-management protocol is
- Simple Network Management Protocol (SNMP)
-- Makes use of TCP/IP protocols

TCP/IP Applications

A few popular application-level services are
- Terminal emulation (TELNET)
- File Transfer Protocol (FTP)
- Simple Mail Transfer Protocol (SMTP)
- Network File System (NFS)
- Simple Network Management Protocol (SNMP)
- Domain Name System (DNS)

TCP/IP Implementation Concerns

Vendors’ TCP/IP implementations should comply with the Official Protocol
Standart

Practical experience suggests that vendors are not 100 percent compliant

May have interoperability problems between vendors’ TCP/IP
implementations
--Differences in interpretation of standards
--Willful ignoring of standard recommendations

This course and other courses in the TCP/IP curriculum will emphasize vendorspecific issues by using the following icon:
