1 1 2010 Geheugen, distributie en netwerken Netwerken: de basis voor distributie van gegevens en taken (processen) –bestaan zo’n 40 jaar, zeer snelle ontwikkeling –“naadloze” inpassing van nieuwe hardware / software –basis daar voor: Protocol Hierarchy Models –security aspecten: in apart college Veel nieuwe ontwikkelingen in gedistribueerde systemen –multi-core computers, parallelle systemen, the Cloud Geheugen –enige lang bestaande onderwerpen (virtueel geheugen) –nieuwe ontwikkelingen

2 2 2010 Introduction Networks Chapter 1

3 3 2010 Transmission Types of transmission methods Broadcast links –wired –wireless –medium access control (chapter 4) Point-to-point links –usually wired –routing

4 4 2010 Wireless-Mobile combination Combinations of wireless networks and mobile computing.

5 5 2010 Local Area Networks Two broadcast networks (a) Bus (b) Ring, hardly used anymore

6 6 2010 Metropolitan Area Networks A metropolitan area network based on cable TV.

7 7 2010 Wide Area Networks Relation between hosts on LANs and the subnet.

8 8 2010 Software Protocol Hierarchies Layers, protocols, and interfaces.

9 9 2010 Information flow information flow supporting virtual communication in layer 5

10 10 2010 Example Hierarchy The philosopher-translator-secretary architecture.

11 11 2010 Design Issues for the Layers Independence Services Addressing Error Control Flow Control Multiplexing Routing

12 12 2010 Connection-Oriented and Connectionless Services Six different types of service.

13 13 2010 TCP/IP –OSI models

14 14 2010 OSI Reference Model The OSI reference model. Nice theoretical framework

15 15 2010 Hybrid Model The hybrid reference model to be used in this book. Best of the two Largely in use, enhanced with “sublayers” Trend: management in third dimension

16 16 2010 Initial TCP/IP protocols Protocols and networks in the TCP/IP model initially.

17 17 2010 IP packets A stream of packets from sender to receiver. Packets may go over different routes Currently practically only IP packets (also for voice), possibly internally packed in larger packets or distributed over smaller cells like in ATM

18 18 2010 IEEE 802 Standards The 802 working groups. The important ones are marked with *. The ones marked with  are hibernating. The one marked with † gave up.
