osi layer for ping

[Shivkumar]

Dear Sirs,

Ping work under which layer of OSI model ?

Thanks,
Shiv

Hi,

Ping uses "ICMP" protocol. This protocol works at Network layer.

osi layer 3

[Shivkumar]

does it use layer 3 or layer 4 ?

[Shivkumar]

what are the protocols in layer 4 ? why layer 4 is basically used ?

[Deoncia Grayson_1]

The fourth layer of the OSI model is the Transport Layer, which is used for data transfer between a source and a destination. data are divided into packets at this layer.

Layer 3 is the Network layer used for network addressing, routing, point-to-point data error detection and recovery. (ping if found in this layer)

[Sameer_Nirmal]

Hi,

The protocols works at OSI layer 4 are
NetBEUI, DLC, SPX/ NWLink, TCP, UDP, RARP, SOCKS, SSL3/ TLS1, PCT, SChannel, WTLS, WDP.

The OSI layer 4 is called as "Transport Layer". At this layer, transport of protocol packets is done. The transport operation consists of sequence & divide/re-combine packets to assure reliability of connections.
The error free delievery of data is achieved tthrough
1.resolving logical address/names by starting sessions of TCP or UDP services used for establishing end-to-end connection between Transport Layer peer computers.
2. sends acknowledgement for data packets received;
3. manages error and flow control.

Hi Shiv:

'ping' would be at the Network layer (layer-3) in the OSI model.

Shiv,

as other's already mentioned, Ping uses ICMP (protocol) at Layer3.

Layer 4: is Transport layer that handles the transmission, reception and error checking of the data.

ping works at layer 3. It is ICMP protocol.

[rick jones]

A purist would say layer 3, but as ICMP makes use of the services of IP, which is itself a layer 3 protocol, one might say that ICMP is a "greater than layer 3" protocol. However, it would be considered a lesser than layer 4 protocol.

Call it Layer 3.5.

This underscores a fundamental point about the OSI model - all those layers are there as much as guidelines to thinking as anything else. If one takes them _too_ literally then bad things happen and one rapidly escallates to layers 8 and 9:

Hi Shiv,
PING is working in Network Layer .

Hi Shiv,
Please find the attached document for more details on OSI Layer.

Hi Shiv,

"ping" uses ICMP requests which is on network layer. Network layer is responsible for switching and routing technologies, creating logical paths, known as virtual circuits, for transmitting data from node to node. Routing and forwarding are functions of this layer, as well as addressing, internetworking, error handling, congestion control and packet sequencing.

Hi Shiv,

Here is a good material on "How Ping works" from Cisco,
