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.

  • 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.

  • 1 Writing Mini-Protocol Stacks As an Aid to Teaching Networking Protocols
    1 Writing Mini-protocol stacks as an aid to teaching networking protocols Anand Richard, Saint Joseph’s College, Rensselaer, IN Introduction Current research literature abounds with many innovations in approaches to teaching networking. Simulators like NS2 (Network Simulator version 2) and NS3 are widely used in academia to teach network protocols. Zenghin and Saroughian present an OSPF (Open Shortest Path First) simulator called the DEVS-Suite (Discrete Event Discrete Time Simulator) that helps students study and understand the OSPF protocol (Zengin & Sarjoughian, 2010). Yang, Yang, Gao, Shen, Zhu and Tan contend “Network protocols are mass, stuffy, abstract and difficult to understand for students to learn” and suggest a layered task based method based on the layered TCP/IP protocol itself as a solution to teach networking (Yang et al., 2010). Feitelson looks at the pros and cons of using two different textbooks by different authors that can be used to teach networking courses (Feitelson, 2007). These text books emphasize building small networks that students can use as labs to gain a better understanding. Feitelson concludes that while these approaches equip the students to become better network administrators they do not do much to make them network researchers. One is inclined to agree with Feitelson because knowing how to use a protocol is only a first step to understanding it. The ‘learn by implementation’ paradigm is also recommended by Uldag and McBride in implementing Bluetooth stacks as a method to teach networking (Uludag & McBride, 2010). We can summarize the approaches in the research literature as a 4 step continuum: 1. Learn what the protocol does.
