  17. What is Telecom? Telecommunicationis the assisted transmission over a distance for the purpose of communication. Telecom companies provide the infrastructure (network) for long distance communication. Examples: Tata Communications Ltd, Reliance Communications Ltd, BSNL etc., A telecommunications network is a network of telecommunication links & nodes arranged so that messages be able to pass from one part of the network to another over multiple links and through various nodes.

  18. Terminologies Bandwidth Speed / Rate • Rate at which the data is transferred from one end to another. • In telecommunications, speed rate is the average number of unit passing between end communicating systems. • This is typically known as upload or download rate. Bandwidth Types • Asymmetric - Upload and download bandwidth differs • Symmetric - Upload and download bandwidth is same Modes • Full Duplex – Systems can send and receive simultaneously • Half Duplex – Systems can either send or receive Port • An interface or hardware where connection is terminated coming from other device. Ex: Serial, Ethernet etc.

  19. Terminologies Protocol • A communication language between systems to exchange information & for management. Ex: TCP/IP or IP, SDH, SIP, BGP Carrier • A Service-provider responsible for carrying information from one end to another. A carrier doesn’t generate any information but itself acts as an agent. Modem/Converter • A device which translates the signal from analogue to digital and vice-versa. • Modem may also perform signaling conversion. Last Mile • A last mile is that section of the network that connects the customer premises to the service provider’s network interfacing location. • Last mile could be on wire line or wireless.

  20. Media Types • Physical media for Telecommunication • Twisted pair • Coaxial cable • Optical fiber • Telecommunication through Free Space • Non-LOS • Broadcast radio frequency including television and radio • Line-of-sight • Communications satellite • Terrestrial Microwave • Wireless LAN/MAN

  21. Type of Networks Local Area Network • Responsible for connecting computers in a much smaller limited physical area. Wide Area Network • Any network that encompasses a large geographic area is referred to as a WAN. Metropolitan Area Network • A MAN is a large network that spans a medium geographic scope falls between a WAN and LAN. Extended Category • Intranet: Refers only to the organization's internal website. E.g. InCompass • Extranet: Extranets extend an Intranet onto the Internet with special provisions for access, authorization and authentication.

  22. Fiber-Optic Cable • Consists of dozens or hundreds of thin strands of glass or plastic that transmit pulsating beams of light rather than electricity. • Unaffected by random electromagnetic interference • It cannot easily be wiretapped, so transmissions are more secure. • It is commonly used for the high-speed backbone lines of network.

  25. Protocol A protocol is a set of rules that enables effective communication to occur. The most popular protocols for networking : TCP / IP – Originally developed for Unix network. It is the protocol for Internet. IPX /SPX – Originally developed by Novell for Netware network. It is still widely used for Windows network. IPX – is Layer 3 protocol and SPX is layer 4 protocol Ethernet – it is low level protocol used with both TCP/IP AND IPX/SPX.

  26. Standard A Standard is an agreed upon Protocol. Standards are industry wide protocol definitions that are not tilted to a particular manufacturer. With standard protocol you can mix and match equipments from different vendors. The most important organizations involved in setting standards are : American National Standards Institute ( ANSI ) Institute of Electrical and Electronic Engineering ( IEEE ) International Organization for Standardization (ISO ) Internet Engineering Task Force ( IETF ) World Wide web Consortium ( W3C )

  28. Application Layer ( Layer 7 ) • Deals with techniques that application programs use to communicate with the network. • Application Programs such as Microsoft Office is NOT part of Application Layer. • It represents the programming interfaces used by application program to request network services. • Examples of Application Layer Protocol – FTP, SMTP, DNS, SMB, Telnet . FTP – File Transfer Protocol DNS – Domain Name System SMTP – Simple Mail Transfer Protocol SMB – Server Message Block

  29. Presentation Layer ( Layer 6 ) • Responsible for how data is represented to application. • Most Computer use ASCII to represent data. However, some computers like IBM Mainframe use EBCDIC . ASCII and EBCDIC are NOT compatible with each other. Presentation Layer converts ASCII to EDCDIC and vice versa. • Also compresses data. ASCII – American Standard Code for Information Interchange EBCDIC – Extended Binary Coded Decimal Interchange Code

  30. Session Layer ( Layer 5 ) • Establishes Sessions between Network Devices. • A session is an exchange of connection oriented transmission between two network devices. • The session layer allows 3 types of transmission modes – Simplex, Half Duplex and Full Duplex.

  31. Transport Layer ( Layer 4 ) • Transports information from one computer to another computer. • The 2 most important layer 4 protocols are – TCP( L3) and SPX. • Important Function – Divide large messages into small packets, establishes connection between network devices, acknowledge the receipt of packets, resends packets that have not been received or corrupted when they arrive.

  32. Network Layer ( Layer 3 ) • Handles the task of routing network messages from one computer to another computer. • The 2 most important layer 3 protocols are – IP and IPX. • Important Function – Logical Addressing and Routing. • The Network Layer Protocol translates IP Address into MAC Address. • Devices – Router

  33. Data Link Layer ( Layer 2 ) • Bottom most layer of OSI Model at which meaning is assigned to the bits that are transmitted over the network. • Addresses things such as size of each packet of the data, means of addressing each packet and way to ensure that two or more nodes do not try to transmit data on the network at the same time. • Provides basic error correction and detection. • Devices – Bridges ( Intelligent Repeater ), Switch ( Intelligent Hub ), Media Access Control Access or MAC Address ( Unique hard wired into every network card by the manufactures. )

  34. Physical Layer ( Layer 1 ) • Bottom most layer of OSI Model. • Addresses the Physical Characteristics of the Network such as type of cable to be used, type of connector to be used, length of cable etc. • Governs the layout of cables and devices such as Repeaters and Hubs. • Devices – Network Adaptor ( also called Network Interface Card or NIC ), Repeater, Hub etc.

  37. What is NAT-ing ? • Network Address Translation (NAT) is the process where a network device, usually a firewall, assigns a public address to a computer (or group of computers) inside a private network. The main use of NAT is to limit the number of public IP addresses an organization or company must use, for both economy and security purposes

  38. Switching

  39. Routing

  40. Difference between Routing and switching • Router understand IP head, and switch deal with MAC address • Router has its own IP address(es), and switch don’t • Router has an operating system running inside, and allow administrator to login into the system. • You (network administrator) must configure routing table to make it works. • Switch is usually ready to use. • Router has routing software running inside, including route discovery protocol. • Routing software know how to deal with different IP packet, such as ICMP and other IP option functionality. Switches don’t. • Multiple routers can be connected together as a network. • You can’t directly multiple switches together to form a large network.
