For example, Microsoft Windows’ Winsock, and Unix’s Berkeley sockets and System V Transport Layer Interface, are interfaces between applications (layer 5 and above) and the transport (layer 4). NDIS and ODI are interfaces between the media (layer 2) and the network protocol (layer 3).
Transport layer offers peer-to-peer and end-to-end connection between two processes on remote hosts. Transport layer takes data from upper layer (i.e. Application layer) and then breaks it into smaller size segments, numbers each byte, and hands over to lower layer (Network Layer) for delivery.
Introduction The transport layer is the fourth layer from the bottom in the OSI reference model. It is responsible for message delivery from process
Transport Layer •E.g. HTTP (used by web services) typically uses TCP • Reliable transport between client and server required •TCP • Stream oriented, not transaction
• used for layer 3 (network layer) forwarding MAC (or LAN or physical or Ethernet) address: • function: used ‘locally” to get frame from one interface to
nicate only with the Network and the Session layers. Finally, the flow of data starts at the Application layer of the sending computer, flows down the layers, across the wire to the receiving computer,

The data unit created at the application layer is called a message, at the transport layer the data unit created is called either a segment or an user datagram, at the network layer the data unit created is called the datagram, at the data link layer the datagram is encapsulated in to a frame and finally transmitted as signals along the transmission media.

The Transport layer also determines what type of service to provide to the Session layer, and, ultimately, to the users of the network. The most popular type of transport connection is an error-free point-to-point channel that delivers messages or bytes in the order in which they were sent.
Computer Networking and Management Page 2 of 9. Here, the channel access protocol serves to coordinate the frame transmissions of the many nodes; Frame headers also often include fields for a node’s so -called physical address, which is completely distinct from the node’s network layer (for example, IP) address.

Notes on Computer Networks v 3. Network layer Climbing up one level above data link layer is the network (or internet) layer. This layer conveys a packet across different networks to any addressable destination. This is split into two units, the first about IP, and the second about routing; it is only split to allow more time to cover it. The topics are: •IP addressing, •packet format
