Introduction and Overview
Introducing TCP/IP networks
- What TCP/IP provides: key application services and multivendor capabilities
- TCP/IP and the Internet
- How Internet RFCs and STDs affect TCP/IP
Introducing TCP/IP protocol architecture
- Protocol layering concepts
- TCP/IP layering
- Components of TCP/IP networks
The Internet Protocol (IP)
Internet Layer functions
- Fundamental internetworking concepts
- Connecting networks
- Providing Physical Layer independence
- Internet addressing: IP address classes A, B, C, D, E
Address resolution
- Resolving MAC addresses with ARP
- Avoiding duplicate IP addresses with RARP, BOOTP and DHCP
IP address resolution
- Building your own IP network
- NIC-registered addresses
- Using private IP addresses: application proxy firewalls
- IPv6
IP on different physical networks
- IP on non-Ethernet LANs: SNAP and LLC
- Using IP on WANs
- IP on ATM
- IP on DSL
Internetworking with IP Routers
Implementing routed networks
- The role of the IP router
- Common IP routing protocols: RIP, OSPF
- Troubleshooting router problems
Going beyond the intranet
- Subdividing IP networks (subnetting)
- Control messages on IP networks: ICMP
- Subnetting and supernetting calculation formulas
- Classless Inter-Domain Routing (CIDR)
- Network Address Translation (NAT)
| Transport and Protocols: TCP and UDP
Transport Layer fundamentals
- The role of the transport protocol
- Reliable vs. best-effort services
The Transmission Control Protocol (TCP)
- Providing a reliable data delivery with TCP
- Associating remote applications using port numbers and process addressing
- TCP packet structure
- TCP performance issues
- Troubleshooting the protocol successfully
The User Datagram Protocol
- Connectionless protocol operation
- Providing reliability at the Application Layer
Applications and Management Protocols
Functions and operation of application protocols
- File transfer protocols: FTP, TFTP
- Network Virtual Terminal (TELNET)
- Employing DNS BIND
- SMTP, the basis of Internet mail
- Utilizing workstation mail: POP3, IMAP4
- Examining the mechanisms of VoIP
Vendor implementations
- Sharing files with NFS
- NFS protocols: RPC, XDR, others
- TCP/IP for Windows Server 2003/NT and XP and UNIX
Managing TCP/IP networks
- SNMP management paradigm
- Simple Network Management Protocol (SNMP)
- The management database: MIB
- SNMP evolution: MIB I and II, RMON, SNMPv2, SNMPv3
Exploring Internet Services
Internet service access methods
- Permanent direct connection
- Building virtual private networks (VPNs) with PPP
Internet service tools
- Retrieving files using Anonymous FTP
- Using World Wide Web (WWW) tools
