Network Protocols Identify the characteristics of TCP/IP, IPX/SPX, NetBIOS, and AppleTalk Understand how network protocols correlate to layers of the OSI Model Identify the core protocols of the TCP/IP suite and describe their functions Identify the well-known ports for key TCP/IP services Understand addressing schemes for TCP/IP, IPX/SPX, NetBEUI, and AppleTalk Describe the purpose and implementation of DNS (Domain Name System) and WINS (Windows Internet Naming Service) Install protocols on Windows XP clients. | NETWORK+ GUIDE TO NETWORKS, FOURTH EDITION Chapter 4 Network Protocols OBJECTIVES Identify the characteristics of TCP/IP, IPX/SPX, NetBIOS, and AppleTalk Understand how network protocols correlate to layers of the OSI Model Identify the core protocols of the TCP/IP suite and describe their functions Identify the well-known ports for key TCP/IP services OBJECTIVES (CONTINUED) Understand addressing schemes for TCP/IP, IPX/SPX, NetBEUI, and AppleTalk Describe the purpose and implementation of DNS (Domain Name System) and WINS (Windows Internet Naming Service) Install protocols on Windows XP clients INTRODUCTION TO PROTOCOLS Protocols vary according to purpose, speed, transmission efficiency, utilization of resources, ease of setup, compatibility, and ability to travel between different LANs Multiprotocol networks: networks running more than one protocol Most popular protocol suite is TCP/IP Others: IPX/SPX, NetBIOS, and AppleTalk TCP/IP (TRANSMISSION CONTROL PROTOCOL/INTERNET . | NETWORK+ GUIDE TO NETWORKS, FOURTH EDITION Chapter 4 Network Protocols OBJECTIVES Identify the characteristics of TCP/IP, IPX/SPX, NetBIOS, and AppleTalk Understand how network protocols correlate to layers of the OSI Model Identify the core protocols of the TCP/IP suite and describe their functions Identify the well-known ports for key TCP/IP services OBJECTIVES (CONTINUED) Understand addressing schemes for TCP/IP, IPX/SPX, NetBEUI, and AppleTalk Describe the purpose and implementation of DNS (Domain Name System) and WINS (Windows Internet Naming Service) Install protocols on Windows XP clients INTRODUCTION TO PROTOCOLS Protocols vary according to purpose, speed, transmission efficiency, utilization of resources, ease of setup, compatibility, and ability to travel between different LANs Multiprotocol networks: networks running more than one protocol Most popular protocol suite is TCP/IP Others: IPX/SPX, NetBIOS, and AppleTalk TCP/IP (TRANSMISSION CONTROL PROTOCOL/INTERNET PROTOCOL) Suite of specialized subprotocols TCP, IP, UDP, ARP, and many others De factor standard on Internet Protocol of choice for LANs and WANs Protocols able to span more than one LAN are routable Can run on virtually any combination of NOSs or network media TCP/IP core protocols operate in Transport or Network layers THE TCP/IP CORE PROTOCOLS: TCP (TRANSMISSION CONTROL PROTOCOL) Provides reliable data delivery services Operates in Transport layer Connection-oriented Ensures reliable data delivery through sequencing and checksums Provides flow control Port hosts address where an application makes itself available to incoming or outgoing data THE TCP/IP CORE PROTOCOLS: TCP (CONTINUED) Figure 4-1: A TCP segment THE TCP/IP CORE PROTOCOLS: TCP (CONTINUED) Figure 4-2: TCP segment data THE TCP/IP CORE PROTOCOLS: TCP (CONTINUED) Figure 4-3: Establishing a TCP connection by three handle UDP (USER DATAGRAM PROTOCOL) Figure 4-4: A UDP segment IP (INTERNET PROTOCOL) Provides information about
