Anyway some datalink layers used by ISPs: Ethernet, PPP, VPLS. It's mostly Ethernet- although cable companies use a different layer 2- Docsis. Wireless ISP might use 802.11 and other wireless L2.
TCP and other higher-layer protocols make sure all 100 are delivered (see TCP/IP). Following are the primary data link protocols: Asynchronous Transmission ...
At the data link layer, we see protocols such as 802.11n wireless, which deal with access to the air and retransmissions between the antennae. So, let’s now return to the question of why RTP has ...
While this makes ISA100.11a highly flexible, the customer must decide which protocol to use. WirelessHART’s decision to specify only HART in the application layer was done to deliver simplicity via ...
In the enterprise, data link protocols provide functions such as finding a path and managing parallel paths. In LANs, the most common kind of learning is finding a path through a set of network ...
Data Link Layer The data link layer is responsible for transmitting packets of information across the link between hosts. If the link is shared by many hosts (for example, a LAN) this layer also ...
The technical name of a frame of data transmitted over the data link layer (layer 2) in a communications network. Ethernet and Token Ring are examples of this layer. Many people neither use the ...
FDT ® offers proven architecture for data exchange between software and automation components, regardless of the network layers or protocols used in communication. Point-to-point connections and ...
The Data Link Layer is one of my favorite layers of the OSI Model. Like a father who loves ALL of his children equally, but in different ways, I also love the other layers, but Layer 2 will always ...
