Interaction Between OSI Layers. In document CCNAEXAM pdf (Page 118-122) Imagine a Web browser displaying a Web page that it received from a Web server. Before that happened, the browser somehow interacted with the software implementing other layers of TCP/IP on the client computer, causing a request to flow to the server. filexlib. The last layer of our upper layers is Layer 5, the Session Layer. This establishes, manages, and terminates sessions between two communicating hosts. The Session Layer also synchronizes dialogue between the Presentation Layer of the two hosts and manages data exchange. For example, we might have web servers that have got many users that are ISO-OSI Model Data Flow Functions (PDU-Protocol Data Unit) 7 - Application (Network processes to applications) (provides services to applications and a window for applications to gain access to the OSI environment.) SIP, Telnet, FTP, HTTP, SMTP, POP, RAS, Client/Server Process Data Interface from the OSI model to the end user's applications.

The upper layers of the OSI model (application, presentation, and session—Layers 7, 6, and 5) are oriented more toward services to the applications. The lower four layers (transport, network, data link, and physical—Layers 4, 3, 2, and 1) are oriented more toward the flows of data from end to end through the network. CCNAs work mostly with
Second, the Network layer must provide encapsulation . During the encapsulation process, Layer 3 receives the Layer 4 PDU and adds a Layer 3 header, or label , to create the Layer 3 PDU. When referring to the Network layer, we call this PDU a packet . Layer 4 PDU + Layer 3 header, or label = packet
They operate at Layer 3 of the OSI model. The Network Layer provides connectivity and path selection between two host systems that may be located on geographically separated networks. The Network Layer is the layer that manages the connectivity of hosts by providing logical addressing. IP addressing is our logical addressing.

As you look at the OSI Model tab with Layer 7 highlighted, a description of what is occurring is listed directly below the In Layers and Out Layers ("1. The DNS client sends a DNS query to the DNS server."). This is very useful information to help understand what is occurring during the communication process. d. Click the Outbound PDU Details tab.
