Message at the data link layer.
The data link layer consists of two sub layers; .
As per the OSI model,Ethernet provides services up to and including the data link layer.
Unlike LANs, you cannot send a data link layer broadcast over Frame Relay.
In IPv6,bit-level error detection for the entire IPv6 packet is performed by the link layer.
The data link layer is often implemented in software as a"network card driver".
Tunneling techniques supporting VPNs such as L2TP orPPTP are used to encapsulate link layer frames(PPP).
Error control: Like the data link layer, the transport layer is responsible for error control.
The processing of any packet sent to a loopback address,is implemented in the link layer of the TCP/IP stack.
Flow control: Like the data link layer, the transport layer is responsible for flow control.
The problem is that to discover information about devices, Windows Vista uses a new protocol,called Link Layer Topology Discovery.
The data link layer lies on top of the physical channel, which maintains the wireless communication between the users and the network.
At first glance, the standards of communication set in the Internet Protocol Suiteseem to be working well enough: the Link Layer puts some data on a wire;
ISO 11898-1 which covers the data link layer, and ISO 11898-2 which covers the CAN physicallayer for high-speed CAN.
The transaction layer receives read and write requests from the software layer andcreates request packets for transmission to the link layer.
Switch works on Layer-2(Data Link Layer), but Layer-3(Network Layer) switches are also available.
Since LVDS is a physical layer specification only, many data communication standards and applications use it butthen add a data link layer.
A frame is"the unit of transmission in a link layer protocol, and consists of a link layer header followed by a packet.".
The link layer can also be the layer where packets are intercepted to be sent over a virtual private network.
MPLS-SHIM specifies that a different label space is used for unicast packets than for multicast packets,and uses a data link layer codepoint to distinguish the two label spaces.
The Data Link layer also provides basic error detection and correction to ensure that the data sent is the same as the data received.
While a repeater is a physical layer device operating on electromagnetic and optical signals,a L2 Switch is a data link layer device that operates on L2 frames.
The IS-95 data link layer only provided"best efforts delivery" for data and circuit switched channel for voice(i.e., a voice frame once every 20 ms).
Access Control: When two or more devices are connected to the same communication channel,then the data link layer protocols are used to determine which device has control over the link at a given time.
Error control: The data link layer adds reliability to the physical layer by adding mechanisms to detect and retransmit damaged or lost frames.
Neighbor Discovery Proxy(ND Proxy)(RFC 4389) provides a service similar to IPv4 Proxy ARP and allows bridging multiple network segments within a single subnet prefixwhen bridging cannot be done at the link layer.
To accomplish these goals, the data link layer takes the packets it gets from the network layer and encapsulates them into frames for transmission.
Access control: When more than two or two devices are connected to the common link, data link layer protocols are necessary to determine which device has control over the link at any point of time.
The HDLC and PPP are the crucial data link layer protocols used in WAN(wide area network) where the HDLC can also be implemented with PPP for the efficient results.
In addition, the managed switch can exchangeinformation between adjacent devices using LLDP(Link Layer Discovery Protocol), which enables PROFINET DCP(Discovery and Configuration Protocol) in accordance with the IEC 61158 standard.
