Looking for the best Ethernet Private Line providers in Charleston, South Carolina? Here's your ultimate guide to making an informed choice.
What is Ethernet Private Line?
Ethernet Private Line is a dedicated, secure Layer 2 data connection between two locations, forming a private network that does not traverse the public internet. This ensures high bandwidth, low latency, and minimal packet loss, making it ideal for businesses requiring reliable and secure WAN connections.
Ethernet Private Line providers are also location-based, as their services depend on the proximity of their network infrastructure to the customer's facilities. This means the availability and quality of service can vary based on the physical location of the endpoints.
