Practical TCP/IP and Ethernet Networking- P64: The transmitter encodes the information into a suitable form to be transmitted over the communications channel. The communications channel moves this signal as electromagnetic energy from the source to one or more destination receivers. The channel may convert this energy from one form to another, such as electrical to optical signals, whilst maintaining the integrity of the information so the recipient can understand the message sent by the transmitter | 298 Index ICMP datagram 107-8 113 IP datagram 107 message structure 107 loop-back testing 82 NetID 82-6 99 164-5 167 177 network ID 80 open shortest path first OSPF 117 119- 20 IP routing protocol 119 IPX or Appletalk protocols 119 network routing tree 120 private networks 86 private vs Internet-unique IP addresses 86 address conflicts 86 disadvantage 86 reverse address resolution protocol RARP 106-7 datagram format 106 diskless workstation 106 drawbacks 107 non-primary servers 107 router see Router routing header 97 101-2 routing information protocol RIP 117-20 authentication 118 distance vector routing protocol 118 IP identification 119 multicasting of RIPv2 messages 119 RIPv2 device 119 routing protocol 114-7 shortest path first SPF 120 source quench 109 quench messages stop 109 speed bandwidth issues 204 static versus dynamic routing 115 default route 115 distance vector dynamic routing 115 dynamic routing 115 enhanced interior routing protocol EIGRP 115 117 119 hybridized routing protocols 115 link state routing protocols 115 metric or yardstick 115 subnet masks 83-5 118 186 172 subnetting 84 LAN segment 84 86 network address 84 subnet ID 84 time-stamp request and replies 113 receive time-stamp 113 round trip time RTT 113 164 structure 113 subnet mask request and reply 114 transmit time-stamp 113 Internet Internet activities board IAB 192 Internet architecture board IAB 193 Internet assigned numbers authority IANA 124 Internet configuration and control board ICCB 192 Internet engineering steering group IESG 192 Internet engineering task force IETF 192 Internet organizational structure 192 Internet research steering group IRSG 192 Internet research task force IRTF 192 Internet service providers ISP 79 86-7 89 198-9 201-2 204 207 Internet standards 192 broadcast solution 212 cardbus 200 246 CDMA cellular technology 210 connection 2-port IP router 202 Micronet s SP86X 201 network address translation NAT 201 via dedicated router 202 via IP sharer 201 via NAT .
