17 17 Brief History of the Internet Late 50s, early 60s: SAGE Late 60s: ARPANET –In 1969 there were 4 nodes: UCLA, UCSB, SRI, U. of Utah –In July 1970: MIT, SDC, RAND and BBN were added Early 70s: TCP/IP (Vint Cerf and Bob Kahn) Late 80s: NSFNET : World Wide Web (Sir Tim Berners-Lee) Early 90s: Commercial Internet NetHui 2012, Auckland

22 22 Evolution of the Internet Connectivity Commodity: plain old data service No integrated infrastructure for service creation New differentiated services Services tailored to market segmentation and value Rapid deployment for services evolution and creation Todays Internet Intelligent Internet Source: Cisco NetHui 2012, Auckland

23 23 Business Requirements are the Driver Do more with less… –Support evolving applications quickly –Scale the network to accept new users –Reduce WAN and management costs –Consolidate infrastructure Source: Cisco NetHui 2012, Auckland

27 27 Internet Architecture Characteristics Characteristics of the Internet that help it scale to meet user demand –Hierarchical –Common standards –Common protocols Source: Cisco

28 Function of Protocol in Network Communication The importance of protocols and how they are used to facilitate communication over data networks –A protocol is a set of predetermined rules Source: Cisco 28NetHui 2012, Auckland

29 Function of Protocol in Network Communication Network protocols are used to allow devices to communicate successfully Source: Cisco 29

30 Function of Protocol in Network Communication Example of different protocols and how they interact Source: Cisco 30NetHui 2012, Auckland

31 Function of Protocol in Network Communication Technology independent Protocols Many diverse types of devices can communicate using the same sets of protocols. This is because protocols specify network functionality, not the underlying technology to support this functionality. Source: Cisco 31NetHui 2012, Auckland

32 Layers with TCP/IP Benefits of using a layered model: - assists in protocol design - fosters competition - changes in one layer do not affect other layers - provides a common language Source: Cisco 32NetHui 2012, Auckland

33 Layers with TCP/IP Protocol data units (PDU) and encapsulation Source: Cisco 33NetHui 2012, Auckland

34 Layers with TCP/IP The process of sending and receiving messages Source: Cisco 34

35 Addressing and Naming Schemes Source: Cisco 35NetHui 2012, Auckland

37 Infrastructure pre- and UFB NetHui 2012, Auckland37 Internet access network market share in the pre UFB world (approx.): 85% are on chorus copper 10% are on other cable networks with remaining 5% mainly mobile Source: NZ Herald, 6 July 2012 UFB:

38 FTTN Cabinet Chorus Internet Infrastructure - Copper Internet Provider www DSLAM Chorus Exchange DSLAM Chorus provides xDSL service to ISPs Each home has ADSL, ADSL2+ or VDSL modem installed Chorus UBA service aggregates traffic from homes and delivers to ISP via handover connection Chorus provides second tier faults service to ISP ISP provides authentication and first tier help desk Analogue voice service provided over same copper pair ISPs can alternatively install their own equipment in exchanges and cabinets then rent dark copper to provide xDSL services NetHui 2012, Auckland38

39 FTTH Cabinet Chorus Internet Infrastructure – UFB Fibre Internet Provider www Chorus Exchange OLT Chorus provides UFB service to ISPs Each home has ONT (Optical Network Terminator) installed with Ethernet and analogue voice ports. Up to 20 homes connected via one fibre to equipment using splitter in cabinet or exchange Chorus UFB service delivers ISP a VLAN with traffic from homes via handover connection Chorus provides 2 nd tier faults service to ISP ISP provides authentication and 1 st tier help desk ISPs can alternatively install their own equipment in exchanges and rent dark fibre to provide services NetHui 2012, Auckland39
