Discuss TCP/IP Architecture ?

TCP/IP Architecture:

• Developed with ARPANET and NSFNET
• Internet Engineering Task Force (IETF)

1. Culture: implement, then standardize
2. OSI culture: standardize, then implement

• Became popular with the release of Berkeley Software Distribution (BSD) Unix; i.e. free software
• Standard suggestions traditionally debated publically through “Request For Comments” (RFC’s)
• Implementation and design have done together
• Hourglass Design (the bottleneck is IP)
• Application vs Application Protocol (FTP, HTTP)
