8 What is X? X Window System Network-based infrastructure for graphical user interface Runs primarily on UNIX and Linux operating systems Sometimes referred to as X11 8

9 First Generation X Two Tier X Windows application (X client) Reflection X (legacy) (PC X server) High speed internal corporate network Two tier architecture: direct TCP connection between X client and X server All components of the X server run on the same system X server runs only on a Windows operating system Unix host 9

10 First Generation X Network issues X Windows application (X client) Low bandwidth Reflection X (legacy) (PC X Server) Unix host 10

11 First Generation X Network issues X Windows application (X client) High latency Reflection X (legacy) (PC X server) Unix host 11

12 First Generation X Limitations X Windows application (X client) X protocol - chatty Reflection X (legacy) (PC X server) Unix host Performance is limited by network bandwidth and latency Can t suspend / resume sessions No built in collaboration / sharing No centralized management 12

14 Next Generation X Three Tier X Windows application (X client) Reflection X Advantage (platform independent X Server) Node Unix host Can distribute X server components Improved performance over latent and constricted networks Can suspend / resume sessions Built in collaboration / sharing Centralized management Platform independence 14

15 Next Generation X Suspend / Resume X Windows application (X client) Office Node Unix host Home 15

16 Next Generation X Sharing X Windows application (X client) You Node Unix host Coworker 16

17 Reflection Advantage 2 or 3 Tier X Windows application (X client) X Server (platform independent) Unix host 17

18 Reflection Advantage 2 or 3 Tier X Windows application (X client) X Server (platform independent) Node Unix host 18

19 Reflection Advantage 2 or 3 Tier X Windows application (X client) X Server (platform independent) Domain Controller (settings repository) Unix host 19
