1 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 Introduction Networks Chapter 1

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

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

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

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

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

8 Software Protocol Hierarchies Layers, protocols, and interfaces.

9 Information flow information flow supporting virtual communication in layer 5

10 Example Hierarchy The philosopher-translator-secretary architecture.

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

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

13 TCP/IP –OSI models

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

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

17 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 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.
