Which OSI layer handles error detection and handling?
Layer 2 of The OSI Model: Data Link Layer provides the functional and procedural means to transfer data between network entities and to detect and possibly correct errors that may occur in the physical layer.
Which of the following protocols working in the physical layer of the OSI model?
Summary
| Layer | Name | Protocols |
|---|---|---|
| Layer 4 | Transport | TCP, UDP |
| Layer 3 | Network | IPV5, IPV6, ICMP, IPSEC, ARP, MPLS. |
| Layer 2 | Data Link | RAPA, PPP, Frame Relay, ATM, Fiber Cable, etc. |
| Layer 1 | Physical | RS232, 100BaseTX, ISDN, 11. |
Can error control be implemented at any layer?
Even with the layers that you can align with some implementations in the real world, not all layers always implement error control. Many layer-1 protocols do not even have error checking. Many, but not all, layer-2 protocols have an error checking, and most that do simply drop damaged frames.
Which OSI layer is responsible for error detection and correction with example?
Data-link layer uses error control techniques to ensure that frames, i.e. bit streams of data, are transmitted from the source to the destination with a certain extent of accuracy.
Which layer is responsible for congestion control?
Transport Layer
5.1 Transport Layer The transport layer is responsible for flow control, congestion control, end-to- end connection setup, and end-to-end reliability.
On which layers the flow control and error control apply?
Flow and error control needs to be done at several layers.
Which layer is OSI model performs network routing flow control and error control function?
The fourth layer of the OSI model ensures complete and reliable delivery of data packets. The transport layer provides mechanisms such as error control, flow control, and congestion control to keep track of the data packets, check for errors and duplication, and resend the information that fails delivery.
