Transport layer provides services to the application layer and takes services from the network layer.<\/p>\n<p><strong>Duties of Transport Layer:-<\/strong><\/p>\n<p>Transport layer is meant for the process to process delivery and it is achieved by performing a number of functions.<\/p>\n<p>Following are the functions of transport layer:-<\/p>\n<p>1. Packetizing:<\/p>\n<ul>\n<li>The transport layer creates packet out of the messages received from the application layer. Packetizing is a process if dividing a long message into smaller ones.<\/li>\n<li>These packets are then encapsulated into data field of the transport layer packet and headers are added .<\/li>\n<li>The length of the message which is to be divided can vary from several lines to several pages.<\/li>\n<\/ul>\n<p>2. Connection Control:<\/p>\n<ul>\n<li>Transport layer protocols maybe divided into following two categories:<\/li>\n<li><em>Connection oriented delivery-\u00a0<\/em>A connection oriented transport layer protocol establishes a connection I.e. virtual path between sender and receiver. This is a virtual connection. The packet may travel out of order. The packets are numbered consecutively and communication is bidirectional.<\/li>\n<li><em>Connectionless delivery-\u00a0<\/em>A connectionless transport protocol will treat each packet independently. There is no connection between them. Each packet can take it&#8217;s own different route.<\/li>\n<\/ul>\n<p>3. Addressing:-<\/p>\n<ul>\n<li>The client needs the address of the remote computer it wants to communicate with.<\/li>\n<li>Such a remote computer have a unique address so that it can be distinguished from the other computers.<\/li>\n<\/ul>\n<p>4. Providing reliability:-<\/p>\n<ul>\n<li>For high reliability the flow of control and error control should be incorporated.<\/li>\n<li>Flow of control provided by transport layer and is used to perform end to end flow rather than across a single link.<\/li>\n<li>Error correction is generally achieved through retransmission.<\/li>\n<\/ul>\n<p><a href=\"http:\/\/www.vskills.in\/certification\/information-technology\">Click here for government certification in Information Technology<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Definition:- The transport layer is the core of the Internet model.
