1 Data Communications and Networking Overview Raj Jain Washington University Saint Louis, MO These slides are available on-line at: 2-1
2 Overview! Data Comm vs Networking vs Distributed Systems! Communications Tasks! Types of Networks! Protocol Layers! ISO/OSI Reference Model! TCP/IP Reference Model 2-2
3 Data Communication vs Networking! Communication: Two Nodes. Mostly EE issues.! Networking: Two or more nodes. More issues, e.g., routing 2-3
4 Distributed Systems vs Networks! Distributed Systems:! Users are unaware of underlying structure. E.g., trn instead of \n\bone\0\trn! Mostly operating systems issues.! Nodes are generally under one organization s control.! Networks: Users specify the location of resources. Nodes are autonomous. Server 2-4
5 Simplified Communications Model! Transmitter: encodes the information 2-5
6 Data Communications: Example! Modem is used to transmit/receive digital information over analog phone system 2-6
7 Communications Tasks! Transmission System Utilization (Multiplexing)! Interfacing! Signal generation (Coding)! Synchronization between transmitter and receiver! Exchange management (Connection Management)! Error detection and correction! Flow control! Addressing! Routing! Recovery! Message formatting! Security! Network Management 2-7
8 Types of Networks! Point to point vs Broadcast WAN Bus LAN Ring LAN! Circuit switched vs packet switched 2-8
9 Types of Networks (Cont)! Enterprise vs Telecom Networks Ethernet is the most common interface in Enterprise Frame relay and ATM are common in Telecom Networks! Local Area Networks (LAN) 0-2 km, Single Ownership Metropolitan Area Networks (MAN) 2-50 km, Wide Area Networks (WAN) 50+ km! Telecom Networks:! Access: Between subscriber and the service provider! Metro: Covering a city! Core: Between cities 2-9
10 An Example Configuration 2-10
11 Protocol Layers! Problem: Philosophers in different countries speak different languages. The Telex system works only with English. I believe there is a God! Philosopher Translator Secretary 2-11
12 A Sample Protocol Architecture 2-12
13 ISO/OSI Reference Model Application Presentation Session Transport Network Datalink Physical File transfer, , Remote Login ASCII Text, Sound Establish/manage connection End-to-end communication: TCP Routing, Addressing: IP Two party communication: Ethernet How to transmit signal: Coding 2-13
14 Service and Protocol Data Units Application 1 Application 2 Application 1 SDU Application 2 Transport PDU Transport Network Access! Service Access Points (SAPs)! Service Data Units (SDUs)! Protocol Data Units (PDUs) Network Access 2-14
15 Service Data Unit (SDU) Application PSDU Presentation SSDU Session TSDU Transport NSDU Network DSDU Datalink PhSDU Physical 2-15
16 Protocol Data Unit (PDU) Application Presentation Session Transport Network Datalink Physical APDU, Message PPDU SPDU TPDU NPDU, Packet DPDU, Frame PhPDU, Frame Application Presentation Session Transport Network Datalink Physical 2-16
17 Use of a Relay 2-17
18 ! Indication = Interrupt Service Primitives Higher Layer Higher Layer Lower Layer Lower Layer 1. Request 2. Indication 3. Response 4. Confirm Unconfirmed service: No confirmation or response 2-18
19 TCP/IP Reference Model! TCP = Transport Control Protocol! IP = Internet Protocol (Routing) TCP/IP Ref Model TCP/IP Protocols Application FTP Telnet HTTP Transport TCP UDP Internetwork IP Host to Network Ether net Point-to- Point Packet Radio Physical Coax Fiber Wireless 2-19
20 OSI vs TCP/IP 2-20
21 OSI vs TCP Reference Models! OSI introduced concept of services, interface, protocols. These were force-fitted to TCP later It is not easy to replace protocols in TCP.! In OSI, reference model was done before protocols. In TCP, protocols were done before the model! OSI: Standardize first, build later TCP: Build first, standardize later! OSI took too long to standardize. TCP/IP was already in wide use by the time.! OSI became too complex.! TCP/IP is not general. Ad hoc. 2-21
22 TCP/IP Concepts Sub Sub! Network Attachment Point (NAP) 2-22
23 PDUs in TCP/IP Architecture Sub Sub 2-23
24 TCP/IP Applications 2-24
25 Summary! Communication, Networks, and Distributed systems! ISO/OSI s 7-layer reference model! TCP/IP has a 5-layer model! PDU, SDU, SAP! Request, Indication, Response, Confirmation 2-25
26 Reading Assignment! Read Chapters 0, 1, and 2 of Stallings 7th Edition Appendix 2A can be skipped at this time! 0.2 Internet and Web Resources! 0.3 Standards! Visit some of the web sites mentioned in 0.2 and
27 Homework! Visit and find the titles of RFC 1 and RFC 780! Submit answers to Problems 2.2 and 2.7 of Stallings 7th Edition! Problem 2.2: Communications between France and China! Problem 2.7: Segmentation and Blocking 2-27
