Network Layer The main purpose of the network layer packet is connecting with the destination; it must be familiar with the topology subnet and choose the appropriate paths through it. When the source and destination are on different networks, the network layer (IP), have to deal with these differences. The services provided by the network layer should be independent of the topology subnet. The transport layer must be protected in the number, type, and topology of this connection subnet addresses are available on the transport layer and should be of a single numbering plan (also LAN and WAN) for data transfer.
Four specific jobs performed by the Network layer:
1- Communication with the Transport layer
Transport layer ensures reliable arrival of messages and offers error mechanisms and data flow control activities. The transport layer provides services for sending "free space", "connection-oriented" and emissions. For connection, transmission, transfer or destination, it can send packets that have to be reconstituted at the other end the whole message. …show more content…
The transport layer encapsulates the application data with data unit. The transport layer protocol creates a virtual flow of data sent and received between the sending applications, divided by the transport port number. The port number identifies a port, a place dedicated to the memory to receive or send data presentation. The services layer protocol transport reliable delivery of the order data. The final result depends on TCP, SCTP, vs UDP handles the
