Our fiber solutions can be tailored and engineered to each unique customer. Unlike national carriers which provide straightforward data services to the masses, we partner with private fiber construction companies which allow us to custom build a data solution based on our customers’ needs.
Layer 2, also known as the data link layer is the second level in the seven-layer OSI Reference model for network protocol design. The 2 sublayers are:
Logical Link control (LLC) sublayer: is responsible for managing communications links and handling frame traffic.
Media access control (MAC) sublayer: governs protocol access to the physical network medium. By using the MAC addresses that are assigned to all ports on a switch, multiple devices on the same physical link can uniquely identify on another.
Layer 2 switches learn MAC addresses automatically, build a table which can be used to selectively forward packets. The benefit of this is when a switch receives packets from MAC address X on Port 1, it knows that packets destined for MAC address X can simply be forwarded out of that port rather than having to try each available port in turn.
