Technology Behind IoT (JNTUK - Unit - 1)
The document discusses the major technologies and components behind IoT systems. It describes the various entities that provide IoT technologies, including hardware, IDEs for developing device software, communication protocols, network backbones, software, internet/cloud platforms, and machine learning algorithms. It outlines the five levels of an IoT system from device platforms to data analytics. Finally, it identifies the key components of an IoT system as physical objects with embedded software and hardware, sensors, control units, communication modules, and software to process messages and commands.
Week11
ISDN is an integrated digital network that allows circuit switching and packet transmission of digitized data communication through a switchboard, trunk or subscriber line. LAN connects computers and printers within the same building using twisted pair cables, coaxial cables or optical fibers to exchange data. TCP is a standard internet protocol that operates at the transport layer of the OSI model and mediates protocols above the session layer. IP addresses distinguish hosts and networks, with the most significant bits specifying the network and the least significant bits specifying the host, and subnet masks are used to distinguish the network and host parts of an IP address.
Week 10 Group C
Network management systems use SNMP to send and receive data from network devices through standardized MIB formats. SNMP works by sending PDUs to agents on devices to retrieve stored data from their MIBs. TCP/IP is the basic communication protocol that allows network components using SNMP to exchange information. Network switches are integral parts of most Ethernet LANs that connect managed switches to route data packets.
Week10
This document discusses several key components of network management systems: Simple Network Management Protocol (SNMP) which allows sending and receiving of data from networked devices; Management Information Base (MIB) which is a database of monitored objects; and network switches which are integral parts of Ethernet local area networks. TCP/IP is also mentioned as the basic communication protocol of the Internet and private networks.
Comprehensive survey on routing protocols for IoT
This document provides an overview of routing protocols for the Internet of Things (IoT). It defines IoT and routing protocols, describes common routing algorithms like distance vector and link state, and discusses specific protocols such as RPL, RIP, and OSPF. It also covers clustering in wireless sensor networks and the LEACH clustering protocol.
Internet connectivity
Internet connectivity relies on a global network of routers that carry data packets from IP protocols from source to destination. Sources send data packets to destinations using standardized IETF formats. Internet connectivity principles involve routers transferring data packets across a global network using IP protocols and standardized formats.
Ipv6
IPv6 is the newest version of the Internet Protocol that provides a 128-bit addressing system to replace IPv4 and address the problem of looming address exhaustion, featuring a vastly expanded address space, simplified header format, and security improvements to meet future networking needs. It was developed by the IETF and became an internet standard in 2017 to support continued growth of devices connected to the internet by providing trillions of addresses for devices using hexadecimal notation groups separated by colons.
Internet protocol
The document discusses Internet Protocol (IP) and Transmission Control Protocol (TCP). It explains that IP allows data packets to be addressed and routed through a network without a direct link between sender and receiver. TCP is a set of rules that defines how computers address and send data to each other. The purpose of IP is to define the basic unit of data transfer (datagram) and perform routing functions. Each datagram contains a header and data. IP addresses uniquely identify devices on the internet and are expressed in decimal format for human readability.

IPv6 or Internet Protocol Version 6 is the next generation internet protocol that will replace the current IPv4 protocol. It features a 128-bit address space compared to IPv4's 32-bit addresses, which allows for vastly more IP addresses needed to meet the increased demands of internet-connected devices. IPv6 also provides improved routing of internet traffic and better built-in security. The presentation discusses key aspects of IPv6 including why the new protocol is needed, its features, address types, addressing structure, advantages over IPv4, and challenges in transitioning to IPv6.
Is Internet getting old !!
The document discusses the limitations of the current TCP/IP network architecture and proposes Recursive Internet Architecture (RINA) as a better alternative. RINA is based on the principle that networking is inter-process communication (IPC) that is recursed over different scopes. It was first presented in 2008 as a new architecture that supports capabilities like mobility, middleboxes, and layer violations without specific mechanisms. RINA structures the network in a way that aims to enhance its structure and economic efficiency compared to the TCP/IP model.
IPv4 and IPv6

IPv4 uses 32-bit addresses represented in decimal form, while IPv6 uses 128-bit addresses in hexadecimal form. The document outlines the classes, types, and terminologies associated with IPv4, and how IPv6 aims to address the exhaustion of IPv4 addresses by supporting a vastly larger number of unique addresses. It concludes by discussing challenges around the deployment of IPv6.
Protocols for internet of things
Internet of Things requires communication to devices that are either actuators or sensors. Each actuator and sensor has an identity. Each actuator and sensor may be either directly connected to the world wide web or indirectly connected via a type of gateway.
Communication to these devices needs to be reliable. Therefore each device may implement their most suitable communication protocol.

Similar to How Circuit-Switched Digital Networks Work
Slide
The document discusses several key concepts in circuit-switched digital networks:
TCP is a transmission control protocol that controls the data link layer and is used for communication processing in TCP/IP. LAN uses Ethernet and TCP/IP, the common internet protocol. ISDN is an integrated digital network that allows both packet and circuit-switched digital communication. IP is the internet protocol that transmits information across the internet. A modem modulates and demodulates signals to allow communication over phone lines.
Ga11
This document provides an overview of circuits-switched digital networks and their key components. It discusses routers and their functions in connecting different networks. It then explains ISDN as a digital network for digital packet transmission and circuit switching data communication. It also covers TCP/IP as a protocol suite used to construct networks and connect computers on the Internet. Finally, it discusses Ethernet as the standard for modern LANs that combines TCP/IP protocols and physical standards.
TCP/IP Modal
The document discusses TCP/IP (Transmission Control Protocol/Internet Protocol), which is a suite of communication protocols used to connect devices on the internet and private networks.

Performance Evaluation of Soft RoCE over 1 Gigabit Ethernet
Abstract: Ethernet is most influential & widely used technology in the world. With the growing demand of low
latency & high throughput technologies like InfiniBand and RoCE have evolved with unique features viz. RDMA
(Remote Direct Memory Access). RDMA is an effective technology, which is used for reducing system load &
improves the performance. InfiniBand is a well known technology, which provides high-bandwidth and lowlatency
and makes optimal use of in-built features like RDMA. With the rapid evolution of InfiniBand technology
and Ethernet lacking the RDMA and zero copy protocol, the Ethernet community has came out with a new
enhancements that bridges the gap between InfiniBand and Ethernet. By adding the RDMA and zero copy
protocol to the Ethernet a new networking technology is evolved called RDMA over Converged Ethernet
(RoCE). RoCE is a standard released by the IBTA standardization body to define RDMA protocol over
Ethernet. With the emergence of lossless Ethernet, RoCE uses InfiniBand efficient transport to provide the
platform for deploying RDMA technology in mainstream data centres over 10GigE, 40GigE and beyond. RoCE
provide all of the InfiniBand benefits transport benefits and well established RDMA ecosystem combined with
converged Ethernet. In this paper, we evaluate the heterogeneous Linux cluster, having multi nodes with fast
interconnects i.e. gigabit Ethernet & Soft RoCE. This paper presents the heterogeneous Linux cluster

Telnet is a network protocol used to provide interactive communication between devices on a network or the internet. A router is a networking device that forwards information and routes traffic. A printer is a computer peripheral that prints text and images onto paper. An IP address is a unique numerical identifier assigned to devices on a network using the Internet Protocol which allows communication between nodes.
Protocols of network in computer science
Network protocols are sets of rules that allow computers to communicate over a network. TCP/IP is a widely used set of protocols that power the internet. TCP/IP was developed in the 1970s-80s and includes protocols like TCP, IP, HTTP, and FTP. Network protocols define data formats, error handling, routing, and other aspects of network communication to ensure reliable data transmission between devices. Common protocols serve functions like file transfer, email delivery, and network management. Protocols provide benefits like increased connectivity and speed for data transmission.
Internet of Things Unit - 01 Part 3A.pptx
The document discusses several key internet protocols:
- Internet Protocol (IP) defines how data is sent between computers over the internet through unique IP addresses.
- Transmission Control Protocol (TCP) establishes and maintains network connections to allow data exchange in a reliable, ordered manner. It guarantees delivery and packet ordering.
- User Datagram Protocol (UDP) provides a simpler connectionless mode of communication compared to TCP, sacrificing reliability for speed. It is used for applications where latency is more important than reliability.
How Circuit-Switched Digital Networks Work
The document discusses how circuit-switched digital networks work. It describes key components like the central office switch, which enables temporary connections between two members. It also discusses dial-up routers, which provide internet access and connect local area networks. High-speed intraswitch trunks allow edge devices to communicate through trunk switches. The document also mentions that TCP/IP protocols are commonly used on the internet and cover data link, network, and transport layers.

POP is a communications protocol used to retrieve emails from a mail server. It was originally called POP but is now referred to as POP3. A terminal adapter (TA) connects a computer to the ISDN network and can also combine the functions of an ISDN TA and a modem, allowing connections over both ISDN and analog lines. The Internet Engineering Task Force (IETF) is an open standards organization that promotes Internet standards, particularly those related to the TCP/IP protocol suite. TCP and IP were the first two networking protocols defined in this standard and form the basis of today's Internet protocols.

"Internet Protocol Suite" prepared by Szymon M. from Poland
The document summarizes the Internet Protocol Suite (TCP/IP), which is the set of communication protocols used for the Internet and similar networks. It consists of four layers - link, internet, transport, and application layers. Some important protocols included in each layer are IP, TCP, UDP, and higher-level protocols like HTTP, FTP, and SMTP. The TCP/IP model uses encapsulation, adding headers at each layer to abstract the protocols and allow communication across networks.
The Internet Protocol Suite (commonly known as TCP/IP)
The Internet Protocol Suite (commonly known as TCP/IP) is the set of communications protocols used for the Internet and other similar networks.
It is named from two of the most important protocols in it:
the Transmission Control Protocol (TCP) and
the Internet Protocol (IP), which were the first two networking protocols defined in this standard.
Network protocals
This document discusses network protocols. It begins with an introduction and history of protocols and defines them as sets of rules that govern communications between devices on a network. Examples of common protocols are then outlined, including TCP/IP, HTTP, FTP, SMTP, UDP, and ICMP. The roles and functions of protocols are explained. Benefits include increased connectivity and transmission speed. The conclusion states that protocols have transformed human communication and networks will continue to evolve.
TCP/IP Protocols
The document provides an overview of protocol architectures and the TCP/IP protocol stack. It discusses how protocol architectures establish rules for exchanging data between systems using layered protocols. The TCP/IP model is then explained in detail through its five layers - physical, network access, internet, transport and application - and core protocols like IP, TCP and UDP. Key differences between IPv4 and IPv6 are also summarized.
Presentation on TCP\IP protocols
This document provides an overview of TCP/IP protocols. It describes the key layers of the TCP/IP model including the application layer, transport layer, network layer, and physical/data link layers. The transport layer contains TCP and UDP which handle transmission reliability and error detection. The network layer deals with packet delivery between networks using IP. Some advantages of TCP/IP are that it is nonproprietary, compatible with all operating systems and hardware. Disadvantages include its large size which can impact small networks and slower speeds due to running multiple layers.
CSS (KNC-301) 2. TCP IP By Vivek Tripathi.pptx
The document discusses the TCP/IP model, which defines how computers connect to the internet and transmit data between networks. It describes TCP/IP's four layered architecture and some key protocols like TCP, IP, HTTP, and FTP. The document also compares TCP/IP to the OSI model and outlines advantages like scalability and operating independently of hardware/software, as well as disadvantages like complexity and high overhead.
Internet Protocol(Samyak Jain 25014).pptx
The document discusses Internet Protocol (IP) which specifies the format of data packets and the addressing scheme used on networks. IP allows for addressing and dropping packets in the network system like a postal system, but does not directly connect the source and recipient. Most networks combine IP with Transmission Control Protocol (TCP) to establish a connection between hosts to send messages back and forth. Commonly used internet protocols include TCP/IP, FTP, and HTTP. IP addresses provide a unique global address for network interfaces and encode network and host numbers. While IPV4 is currently used, IPV6 is designed to replace it and provide more addresses and functionality for future internet growth.

TCP/IP-Protocol Suite-Simple Explanation
This document provides an overview of the TCP/IP model and its layers:
1) The application layer allows applications to access networked services and contains high-level protocols like HTTP, SMTP, and FTP. It uses both TCP and UDP depending on reliability needs.
2) The transport layer delivers application data using TCP and UDP, choosing the protocol based on reliability requirements. TCP provides error checking while UDP does not.
3) The internet layer handles data routing using IP. ICMP and IGMP are also used at this layer.
4) The network interface layer consists of device drivers and network interface cards that handle physical communication over cables or other media.
