transfer information. TCP/IP is responsible for transmitting the data and to make sure that the data makes it to the correct address. The link that is used to search for the web page is separated in to different sections, the link layer, the internet layer, the transport layer and the application layer. These layers each have a job and provide the internet what to search for. The link layer navigates through routers to reach where it needs to be.

4. link layer encapsulates the datagram received from the network layer into a frame? In order for a datagram to be transferred from source host to destination host, it must be moved over each of the individual links in the end-to-end path. Over a given link, a transmitting node encapsulates the datagram in a link-layer frame and transmits the frame into the link; the receiving node then receives the frame and extracts the datagram. A link-layer protocol is used to move a datagram over an individual

Solution Scope Our network solution will be MPLS IP VPN; MPLS IP VPN is a fast, packet data transport service that uses high speed switching architecture instead of the typical routers. This type of network will be a change from your traditional network; it will make sure that packet-forwarding decisions are made solely on the contents of this label, without examining the packets. It will also allow all individuals to create end-to-end circuits across any type of transport medium, while using any

What are the parts of TCP/IP and what do they do? Who is the primary user of TCP/IP? TCP performs packetizing: breaking the data into smaller packets, numbering ensuring each packet is reliably delivered, and putting them in the proper order at the destination. IP performs routing and addressing. IP software is used at each of the intervening computers through which the message passes; it is IP that routes the message to the final destination. The TCP software only needs to be active at the sender
