SECTION 1 OSI, Objective 1 01 Explain compare and contrast the. OSI layers, 1 01 Describe the function of each OSI layer.
Ref 1 pp 168 181, Networking Basics Part 17 The OSI Model. The OSI Model s Seven Layers Defined and Functions Explained. The OSI Model, The term OSI Model is short for Open System Interconnection Basic Reference Model The OSI Model. consists of seven different layers Each layer of the model is designed so that it can perform a specific task. and facilitates communications between the layer above it and the layer below it You can see what the OSI. Model looks like in the figure below, The Application Layer. The top layer of the OSI model is the Application layer The first thing that you need to understand about the. application layer is that it does not refer to the actual applications that users run Instead it provides the. framework that the actual applications run on top of. F5 STUDY GUIDE 101 Application Delivery Fundamentals. To understand what the application layer does suppose that a user wanted to use Internet Explorer to open. an FTP session and transfer a file In this particular case the application layer would define the file transfer. protocol This protocol is not directly accessible to the end user The end user must still use an application. that is designed to interact with the file transfer protocol In this case Internet Explorer would be that. application, The Presentation Layer, The presentation layer does some rather complex things but everything that the presentation layer does can. be summed up in one sentence The presentation layer takes the data that is provided by the application layer. and converts it into a standard format that the other layers can understand Likewise this layer converts the. inbound data that is received from the session layer into something that the application layer can understand. The reason why this layer is necessary is because applications handle data differently from one another In. order for network communications to function properly the data needs to be structured in a standard way. The Session Layer, Once the data has been put into the correct format the sending host must establish a session with the.
receiving host This is where the session layer comes into play It is responsible for establishing maintaining. and eventually terminating the session with the remote host. The interesting thing about the session layer is that it is more closely related to the application layer than it is. to the physical layer It is easy to think of connecting a network session as being a hardware function but. sessions are established between applications If a user is running multiple applications several of those. applications may have established sessions with remote resources at any time. The Transport Layer, The Transport layer is responsible for maintaining flow control An operating system allows users to run. multiple applications simultaneously and it is therefore possible that multiple applications may need to. communicate over the network simultaneously The Transport Layer takes the data from each application. and integrates it all into a single stream This layer is also responsible for providing error checking and. performing data recovery when necessary In essence the Transport Layer is responsible for ensuring that. all of the data makes it from the sending host to the receiving host. The Network Layer, The Network Layer is responsible for determining how the data will reach the recipient This layer handles. things like addressing routing and logical protocols Since this series is geared toward beginners I do not. want to get too technical but I will tell you that the Network Layer creates logical paths known as virtual. circuits between the source and destination hosts This circuit provides the individual packets with a way to. F5 STUDY GUIDE 101 Application Delivery Fundamentals. reach their destination The Network Layer is also responsible for its own error handling and for packet. sequencing and congestion control, Packet sequencing is necessary because each protocol limits the maximum size of a packet The amount of. data that must be transmitted often exceeds the maximum packet size Therefore the data is fragmented into. multiple packets When this happens the Network Layer assigns each packet a sequence number When. the data is received by the remote host that device s Network layer examines the sequence numbers of the. inbound packets and uses the sequence number to reassemble the data and to figure out if any packets. are missing If you are having trouble understanding this concept then imagine that you need to mail a large. document to a friend but do not have a big enough envelope You could put a few pages into several small. envelopes and then label the envelopes so that your friend knows what order the pages go in This is exactly. the same thing that the Network Layer does, The Data Link Layer. The data link layer can be sub divided into two other layers the Media Access Control MAC layer and the. Logical Link Control LLC layer The MAC layer basically establishes the computer s identity on the network. via its MAC address A MAC address is the address that is assigned to a network adapter at the hardware. level This is the address that is ultimately used when sending and receiving packets The LLC layer controls. frame synchronization and provides a degree of error checking. The Physical Layer, The physical layer of the OSI model refers to the actual hardware specifications The Physical Layer defines.
characteristics such as timing and voltage The physical layer defines the hardware specifications used by. network adapters and by the network cables assuming that the connection is not wireless To put it simply. the physical layer defines what it means to transmit and to receive data. 1 01 Differentiate between the OSI layers, OSI Open Source Interconnection 7 Layer Model. OSI Layers, Application Layer 7, This layer supports application and end user processes Communication partners are identified quality of. service is identified user authentication and privacy are considered and any constraints on data syntax. are identified Everything at this layer is application specific This layer provides application services for file. transfers e mail and other network software services. F5 STUDY GUIDE 101 Application Delivery Fundamentals. Presentation Layer 6, This layer provides independence from differences in data representation e g encryption by translating. from application to network format and vice versa This layer formats and encrypts data to be sent across. a network providing freedom from compatibility problems It is sometimes called the syntax layer. Transport Layer 4, This layer provides transparent transfer of data between end systems or hosts and is responsible for end to. end error recovery and flow control It ensures complete data transfer. Network Layer 3, This layer provides switching and routing technologies creating logical paths known as virtual circuits for.
transmitting data from node to node Routing and forwarding are functions of this layer as well as addressing. internetworking error handling congestion control and packet sequencing. Network Layer 2, This layer provides switching and routing technologies creating logical paths known as virtual circuits for. transmitting data from node to node Routing and forwarding are functions of this layer as well as addressing. internetworking error handling congestion control and packet sequencing. F5 STUDY GUIDE 101 Application Delivery Fundamentals. 1 01 Describe the purpose of the various address types at different. OSI layers, OSI layers functional, 1 Physical Hubs Repeaters Cables Optical Fiber SONET SDN Coaxial Cable Twisted Pair Cable and. Connectors, 2 Data Link 802 11 WLAN Wi Fi WiMAX ATM Ethernet Token Ring Frame Relay PPTP L2TP and ISDN. 3 Network IPv4 IPV6 IPX OSPF ICMP IGMP and ARP, 4 Transport TCP SPX and UDP. 5 Session layer Logical Ports 21 22 23 80 etc, 6 Presentation layer SSL WEP WPA Kerberos.
7 Application Layer DHCP DNS FTP HTTP IMAP4 NNTP POP3 SMTP SNMP SSH TELNET and NTP. Objective 1 02 Explain Protocols and Technologies, Specific to the Data Link Layer. 1 02 Explain the purpose of a switch s forwarding database. Forwarding Database, A forwarding database is a table used by a Layer 2 device switch bridge to store the learned MAC addresses. of nodes on the attached local broadcast domain domains VLANS and the port interface that MAC address. was learned on The MAC addresses are learned transparently as the switch forwards traffic. How it works, When an Ethernet frame arrives at a Layer 2 device the Layer 2 device will inspect the source MAC address of. the frame and associate it to the port that the frame arrived on in the forwarding database This simply creates a. table that can be cross referenced for device locations When the table is populated it allows the Layer 2 device. to look at the destination MAC address of the arriving Ethernet frame and find the destination port for that MAC. address to know where to send that specific Ethernet frame If the FDB table doesn t have any information on.
