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.

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 ...

TCP and other higher-layer protocols make sure all 100 are delivered (see TCP/IP). Following are the primary data link protocols: Asynchronous Transmission ...

Building enterprise networks with routers and switches requires interoperability of key protocols at Layer 2 and Layer 3. Without them, the network falls apart; with them, it’s a finely tuned and ...

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 ...

Fig. 3: The ultra Ethernet stack includes transport and network layers, with the transport layer being mandatory. So far, the network layer employs IP with no changes. The data-link and physical ...

The set of protocols used in a communications network. A protocol stack is a prescribed hierarchy of software layers, starting from the application layer at the top (the source of the data being ...

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 ...
