The Illustrated Network- P82

The Illustrated Network- P82:In this chapter, you will learn about the protocol stack used on the global public Internet and how these protocols have been evolving in today’s world. We’ll review some key basic defi nitions and see the network used to illustrate all of the examples in this book, as well as the packet content, the role that hosts and routers play on the network, and how graphic user and command line interfaces (GUI and CLI, respectively) both are used to interact with devices. | Index 779 routing 218-19 routing tables 322-23 SNMP 610-11 sockets 302-3 SONET link display 76-78 SSH 634-35 SSL 586-87 TCP 280-81 UDP 260-61 VLANs 660-61 VoIP 736-37 VPLS 673 Web servers 560-61 Web sites 586-87 wireless link display 81-83 In-band management 248 Independent basic service set IBSS 98 Indirect delivery 229 packet destination address 232-33 router and 231-34 Informational RFCs 20 Ingress routers 446 450 Institute of Electrical and Electronics Engineers IEEE .
