Application Layer
• Combines the Application, Presentation and Session Layers of the OSI Model
• Server Message Block (SMB)– Use of network applications and files
Transport Layer
• Remote end-to-end data transfer
• Protocols– TCP– User Datagram
Protocol (UDP)

Transport Layer Protocols
• TCP– Fixed connection– Data delivery verification– Full duplex
• UDP– Connectionless– No verification

Internetwork Layer
• Responsible for routing data
• Protocols– IP– Internet Control Message Protocol (ICMP)– Address Resolution Protocol (ARP)– Reverse Address Resolution Protocol (RARP)– Routing Information Protocol (RIP)– Open Shortest Path First (OSPF)– Dynamic Host Configuration Protocol (DHCP)
Internetwork Layer Protocols
• IP– Connectionless– Breaks down data– Addressing – Ex: 12.133.222.15
• ICMP– Delivered in IP packets– Error messaging
Internetwork Layer Protocols
• ARP– Maps IP addresses to MAC addresses– 411 service
• RARP– IP address request from gateway server cache
• RIP– Factors number of hops
Internetwork Layer Protocols
• OSPF– No hop limit– Reroute data
• DHCP– Provides client’s IP addresses– Eliminates static IP addresses– Bootstrap Protocol (BOOTP)
Network Interface Layer
• Provides the interface to hardware
• Defines necessary hardware characteristics.– Voltage levels– Pin configurations– Cable requirements
