OSI Model and Network Protocols
CHAPTER4 FOUR OSI Model and Network Protocols Objectives 1.1 Explain the function of common networking protocols . TCP . FTP . UDP . TCP/IP suite . DHCP . TFTP . DNS . HTTP(S) . ARP . SIP (VoIP) . RTP (VoIP) . SSH . POP3 . NTP . IMAP4 . Telnet . SMTP . SNMP2/3 . ICMP . IGMP . TLS 134 Chapter 4: OSI Model and Network Protocols 4.1 Explain the function of each layer of the OSI model . Layer 1 – physical . Layer 2 – data link . Layer 3 – network . Layer 4 – transport . Layer 5 – session . Layer 6 – presentation . Layer 7 – application What You Need To Know . Identify the seven layers of the OSI model. Identify the function of each layer of the OSI model. Identify the layer at which networking devices function. Identify the function of various networking protocols. Introduction One of the most important networking concepts to understand is the Open Systems Interconnect (OSI) reference model. This conceptual model, created by the International Organization for Standardization (ISO) in 1978 and revised in 1984, describes a network architecture that allows data to be passed between computer systems. This chapter looks at the OSI model and describes how it relates to real-world networking. It also examines how common network devices relate to the OSI model. Even though the OSI model is conceptual, an appreciation of its purpose and function can help you better understand how protocol suites and network architectures work in practical applications. The OSI Seven-Layer Model As shown in Figure 4.1, the OSI reference model is built, bottom to top, in the following order: physical, data link, network, transport, session, presentation, and application. -
Lecture: TCP/IP 2
TCP/IP- Lecture 2 [email protected] How TCP/IP Works • The four-layer model is a common model for describing TCP/IP networking, but it isn’t the only model. • The ARPAnet model, for instance, as described in RFC 871, describes three layers: the Network Interface layer, the Host-to- Host layer, and the Process-Level/Applications layer. • Other descriptions of TCP/IP call for a five-layer model, with Physical and Data Link layers in place of the Network Access layer (to match OSI). Still other models might exclude either the Network Access or the Application layer, which are less uniform and harder to define than the intermediate layers. • The names of the layers also vary. The ARPAnet layer names still appear in some discussions of TCP/IP, and the Internet layer is sometimes called the Internetwork layer or the Network layer. [email protected] 2 [email protected] 3 TCP/IP Model • Network Access layer: Provides an interface with the physical network. Formats the data for the transmission medium and addresses data for the subnet based on physical hardware addresses. Provides error control for data delivered on the physical network. • Internet layer: Provides logical, hardware-independent addressing so that data can pass among subnets with different physical architectures. Provides routing to reduce traffic and support delivery across the internetwork. (The term internetwork refers to an interconnected, greater network of local area networks (LANs), such as what you find in a large company or on the Internet.) Relates physical addresses (used at the Network Access layer) to logical addresses. -

A Comparison of Iot Application Layer Protocols Through a Smart Parking Implementation
A Comparison of IoT application layer protocols through a smart parking implementation Paridhika Kayal and Harry Perros {pkayal,hp}@ncsu.edu Computer Science Department North Carolina State University Abstract—Several IoT protocols have been introduced in order to high performance, real-time data sharing or real-time device provide an efficient communication for resource-constrained control. In many cases data is collected for subsequent applications. However, their performance is not as yet well “offline” processing. The WebSocket (WS) standard provides understood. To address this issue, we evaluated and compared bi-directional Web communication and connection four communication protocols, namely, CoAP, MQTT, XMPP, management. WebSocket is a good IoT solution if the devices and WebSocket. For this, we implemented a smart parking application using open source software for these protocols and can afford the WebSocket payload. Other protocols, such as, measured their response time by varying the traffic load. SMQ and CoSIP are also gaining traction. All these protocols Keywords—CoAP, MQTT, XMPP, WebSocket, smart parking, are positioned as real-time publish-subscribe IoT protocols, response time. with support for millions of devices. Depending on how you define “real time” (seconds, milliseconds or microseconds) I.

2017 21st International Conference on Control Systems and Computer Science Security in the Internet of Things: A Survey on Application Layer Protocols Lavinia Năstase Faculty of Automatic Control and Computer Science, University Politehnica of Bucharest, Romania [email protected] Abstract – The rapid development of technology provide a critical approach towards the security of each one nowadays led people to a new and revolutionary concept, of them. We also make a comparison of the discussed named the Internet of Things. This model imposes that protocols. Section IV focuses on vulnerabilities and all “objects”, such as personal objects (smartphones, possible issues in the application layer. The last two notebooks, smart watches, tablets etc), electronic equipment embed with sensors and other environmental sections provide some ideas for future research in this field elements are always connected to a common network. and conclusions on the paper. Therefore, one can access any resource at any time, by using a device recognized in the network. While the IoT II. IOT GENERAL ARCHITECTURE may be economically and socially beneficial, the Figure 1 illustrates the main underlying technologies, implementation of such a system poses many difficulties, according to [1], as following: risks and security issues that must be taken into consideration. Nowadays, the architecture of the Internet - RFID (Radiofrequency identification), that uses a tag must be updated and rethought in order to interconnect to identify and track the objects to which they are trillions of devices and to ensure interoperability between attached, them. Nevertheless, the most important problem is the - Sensors, that have the purpose of collecting data and security requirements of the IoT, which is probably one digitizing it for further processing, and actuators, for of the main reasons of the relatively slow development of this field. -
How to Make a Communication System Using Sora Devise
How to Make a Communication System using Sora Devise Amir Aghdasi [email protected] Abstract Tried to demonstrate and simplify the way that Sora Board works and explained how components in Sora associate each-others I. TCP/IP A layer is a collection of conceptually similar functions that provide services to the layer above it and receives services from the layer below it. This is a new version of OSI model. Everything had been explained in TCP/IP but associated in the way that how OSI model modified. A. Application Layer: In OSI model Presentation Layer and Session Layer and also application layer were separated but in TCP/IP layer , they are all defined within application layer. Both OSI model and TCP/IP model has the application. application layers are included all appllications layers that are in the windows, but all application which are existed on the windows and also are not changeable(????). application layer is a term of categorizing the protocol. in TCP/IP , the application layer contains all protocol and methods that fall into the process of communication in IP. B.TCP( Transmission Control Protocol): TCP is a protocol that most of Internet applicants can rely on it such as the World Wide Web, e-mail, and file transfer. TCP provides ordered delivery and reliable of a stream of bytes from a program on one computer to another program on another computer. TCP is one of the main protocol in Internet Protocol Suite . TCP is one of the two original of Suit and it complements the Internet Protocol which is IP and consequently these two layers and the whole collection are know as a TCP/IP. -
