However, both will be dwarfed by the anticipated emergence of the Internet of Things (IoT), in which everyday objects are able to connect to the Internet, tweet or be queried. Whilst the impact onto economies and societies around the world is undisputed, the technologies facilitating such a ubiquitous connectivity have struggled so far and only recently commenced to take shape. To this end, this paper introduces in a timely manner the cornerstones of a technically and commercially viable IoT which includes a detailed discussion on the particular standard of choice at each protocol layer. This stack is shown to meet the important criteria of power-efficiency, reliability and Internet connectivity. Industrial applications have been the early adopters of this stack, which has become the de-facto standard, thereby bootstraping early IoT developments. -

Comparison of OSI and TCP/IP Reference Model
Department Of Computer Application Dr. Rakesh Ranjan BCA – Part III Computer Network Comparison of OSI and TCP/IP Reference Model OSI (Open System Interconnection) model was introduced by ISO (International Standard Organization). Currently OSI (Open System Interconnection) model is just a reference model. Means that, there are no real working implementations of OSI Model on any of latest network infrastructure devices or Operating Systems. OSI (Open System Interconnection) model is used these days only as a reference model for teaching computer networking concepts and for understanding how computer networks operate. The roots of TCP/IP (Transmission Control Protocol Internet Protocol) are with US Department of Defense (DoD). Original TCP/IP (Transmission Control Protocol/Internet Protocol) model had only four layers, and later an updated model evolved with five layers. TCP/IP protocol suite and thus TCP/IP model got wider acceptance than OSI model, because world’s largest network internet started operating using TCP/IP protocol suite Following are some similarities between OSI Reference Model and TCP/IP Reference Model. Both have layered architecture. Layers provide similar functionalities. Both are protocol stack. Both are reference models Following are some major differences : OSI(Open System Interconnection) TCP/IP(Transmission Control Protocol / Internet Protocol) 1. OSI is a generic, protocol independent 1. TCP/IP model is based on standard protocols standard, acting as a communication around which the Internet has developed. It is a gateway between the network and end communication protocol, which allows connection user. of hosts over a network. 2. In OSI model the transport layer 2. In TCP/IP model the transport layer does not guarantees the delivery of packets. -

A Network Protocol Stack in Standard ML∗
Higher-Order and Symbolic Computation, 14, 309–356, 2001 c 2002 Kluwer Academic Publishers. Manufactured in The Netherlands. A Network Protocol Stack in Standard ML∗ EDOARDO BIAGIONI [email protected] University of Hawai’i at Manoa,¯ ICS Department, 1680 East-West Road, Honolulu HI 96822, USA ROBERT HARPER [email protected] PETER LEE [email protected] Carnegie Mellon University, School of Computer Science, 5000 Forbes Avenue, Pittsburgh PA 15213, USA Abstract. The FoxNet is an implementation of the standard TCP/IP networking protocol stack using the Standard ML (SML) language. SML is a type-safe programming language with garbage collection, a unique and advanced module system, and machine-independent semantics. The FoxNet is a user-space implementation of TCP/IP that is built in SML by composing modular protocol elements; each element independently implements one of the standard protocols. One specific combination of these elements implements the standard TCP/IP stack. Other combinations are also possible and can be used to easily and conveniently build custom, non-standard networking stacks. This paper describes in detail the final design and implementation of the FoxNet, including many of the details that are crucially affected by the choice of SML as the programming language. Keywords: Standard ML, computer networks, modules, signatures, types 1. Introduction The Fox project was started in 1991 with the goal of writing systems-level code in high-level programming languages. The purpose of doing this was and is twofold: to improve the state of the art in systems development by using more advanced languages, and to challenge both the design and implementations of advanced languages by applying them to some of the hardest programming problems known.
