TAILIEUCHUNG - Lecture Network Certification: Chapter 6 - Microsoft Press

Chapter 6 - Network layer protocols. Chapter summary: Network layer protocols are responsible for end-to-end communications across the network; IP is a connectionless protocol that encapsulates transport layer data into datagrams; IPX is a proprietary standard that performs routing, addressing, and protocol identification; NetBIOS Extended User Interface (NetBEUI) is used by small Windows networks for LAN networking; AppleTalk provides basic networking to small networks. | Chapter Overview IP IPX NetBEUI AppleTalk Network Layer Protocols Responsible for end-to-end communications on an internetwork Contrast with data-link layer protocols, which provide communications on the same local area network (LAN) IP Encapsulation IP Functions Encapsulation Addressing Routing Fragmentation Protocol identification The IP Datagram Format IP Addresses Internet Protocol (IP) is the only network layer protocol with its own addressing system. IP addresses are 32 bits long. IP addresses have two parts: a network identifier and a host identifier. IP addresses are assigned to network interface adapters, not to computers. The Source IP Address field in the IP header always identifies the computer that generated the packet. The Destination IP Address field in the IP header always identifies the packet’s final destination. End Systems and Intermediate Systems Fragmentation Routers connect networks that support different-sized packets. The largest .
