Session Layer creates procedures for checkpointing followed by adjournment, restart and termination.This layer also controls single or multiple connections for each-end user application and directly communicates with both Presentation and transport layers.The Session Layer is also responsible for synchronizing information from different sources.The services offered by Session Layer are generally implemented in application environments using remote procedure calls (RPCs).This layer basically provides a mechanism of opening, closing and managing a session between the end-user application processes.This layer is also responsible for session checkpointing and recovery.This layer allows synchronization by allowing the process of adding checkpoints, which are considered as synchronization points to the streams of data.This layer is also responsible for token management, through which it prevents two users to simultaneously access or attempting the same critical operation.

Session Layer works as a dialog controller through which it allows systems to communicate in either half-duplex mode or full duplex mode of communication.Data from Presentation Layer Session layer Data from Transport Layerįollowing are some of the functions which are performed by Session Layer – The session layer being the fifth layer in the OSI model performs several different as well as important functions which are need for establishing as well as maintaining a safe and secure connection. The ability to send larger amount of data files is extremely important and a necessary thing too. Then at last, we need to monitor Data Transfer phase properly. Then we further need to transmit limited transparent user data. Next thing is we need to take care of the negotiations which should happen between session parameters. The second thing is that we need to select the required transport quality of service (also referred as QoS) parameters. Now, in order to establish a session connection, several things should be followed.įirst thing is we should map the session address to the shipping address. Session Layer, which is the 5th layer in the OSI model, uses the services provided by The transport layer, enables applications to establish and maintain sessions and to synchronize the sessions. This layer handles and manipulates data which it receives from the Session Layer as well as from the Presentation Layer. This layer basically establishes a connection between the session entities. In Session Layer, streams of data are received and further marked, which is then resynchronized properly, so that the ends of the messages are not cut initially and further data loss is avoided. It is responsible for establishing, maintaining, synchronizing, terminating sessions between end-user applications. This layer allows users on different machines to establish active communications sessions between them. The Session Layer is the 5th layer in the Open System Interconnection (OSI) model.
