Tcp/ip vs iso

They serve similar purposes, so the comparisons are inevitable. How are they similar to or different from each other?

Which one is better? Does it make sense to compare the two? It involves four layers, namely the application, transport, internet, and link layers. The OSI model can be described as a more comprehensive reference networking framework. These are the application, presentation, session, transport, network, data link, and physical layers. The OSI model partitions data flow into these seven layers, with each layer serving as a class of functions that connects the previous layer to a higher layer.

This model was developed in the late s and was eventually adopted as a working product of the Open Systems Interconnection Group at the International Organization for Standardization. It only has the application layer directly above the transport layer. The session layer controls the dialogues connections between computers.

It establishes, manages, maintains and ultimately terminates the connections between the local and remote application. Layer 5 software also handles authentication and authorization functions. It verifies the data is delivered as well. The session layer is commonly implemented explicitly in application environments that use remote procedure calls. The transport layer provides the functions and means of transferring data sequences from a source to a destination host via one or more networks, while maintaining the quality of service QoS functions and ensure the complete delivery of the data.

The integrity of the data can be guaranteed via error correction and similar functions. It can also provide explicit flow control function. The network layer handles packet routing via logical addressing and switching functions. A network is a medium to which many nodes can be connected. Every node has an address. When a node needs to transfer message to other nodes, it can merely provide the content of the massage and the address of the destination node, then the network will find the way to deliver the message to the destination node, possibly routing through other nodes.

If the message is too long, the network may split it into several segments at one node, sending them separately and reassembling the fragments at another node.

The data link layer provides node-to-node transfer—a link between two directly connected nodes. It handles packaging and unpacking the data in frames. It defines the protocol to establish and terminate a connection between two physically connected devices, such as Point-to-Point Protocol PPP.

The data link layer is generally divided into two sublayers—media access control MAC layer and logical link control LLC layer. MAC layer is responsible for controlling how devices in a network gain access to a media and permission to transmit data.

But how stable it would be, is related to the application. Register Login. Industry Online Support. Product Support Services Forum mySupport. Rating 4. Thanks Experienced Member. Platinum Expert.
