IP protocols are defined in the relevant IETF RFCs. The networks topologies may be based on LANs (e.g. Ethe

48、rnet), Point to Point leased lines, PSTN, ISDN, X.25 or WANs using switched technology (e.g. SMDS, ATM). 4.3 Key characteristics of Ethernet The Ethernet is a family of computer networking technologies commonly used in LAN and is often used to refer to all Carrier Sense Multiple Access/Collision Det
