What protocol does my ISP (Verizon) use at the data link layer to transport them? Google has not been much help so far.

In networking and communications, the formats, codes and procedures for transmitting a unit of data (frame, packet) from one node to another. Known as a "layer 2 protocol," the data link protocol ...

On a shared medium, data link addresses are unique within the medium. In the enterprise, data link protocols provide functions such as finding a path and managing parallel paths.

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 ...

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 ...

A protocol stack is a prescribed hierarchy of software layers, starting from the application layer at the top (the source of the data being sent) to the data link layer at the bottom (transmitting ...

The data-link and physical layers add new optional features. Elements in blue are required, those in green are unchanged from Ethernet, and those in beige are optional.

It is also worth noting that most underlying link layer protocols such as Ethernet or similar MAC-based systems may discard damaged frames of data anyway unless something interfaces with those link ...

Network Layer: Handles routing of data packets across networks and includes protocols like IP. Transport Layer: Ensures reliable data transfer and includes protocols like TCP and UDP. Session Layer: ...
