What is TCP/IP(continued)
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
Proprietary Networks (continued)
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 ApplicationsTCP/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 vendor-
specific issues by using the following icon:
