What is ILL (Internet Lease Line)? Different Between ILL and Broadband Internet?

 Internet Lease Line is a fixed circuit line & an enterprise-grade service which provides full-duplex, symmetric, and fixed dedicated speed to an enterprise. It is backed by the Service Level Agreements (SLAs) for better scalability & reliability.

To caters different requirements in businesses ILL plans come in various ranges from 2-Mbps, 5-Mbps to 1-Gbps. All the range can give symmetrical speed so the user can Download and Upload their files without any hassle or waiting for better network connectivity. Businesses can subscribe desired plan as per their requirement and need.

On the other hand, Broadband Internet is purely designed for home users. In broadband, users get the asymmetric speed and the speed is not dedicated all time. If the user subscribes to a 10-Mbps Broadband plan, then they would get up to 10-Mbps speed for Download and 2-Mbps for upload because Bandwidth is shared with other users. The reason of it that broadband users are more focused on downloading instead of uploading the data. When all users start using the internet at the same time, it is hard to get the subscribed speed. The user will get the speed as per its availability at the provider nodes.

Choosing an Internet Lease Line for your business provide many benefits like:

1. Dedicated Speed: With ILL businesses can have the dedicated speed as per their plans, their bandwidth won't be shared with others. As you have experienced in Broadband Internet, sometimes your connection speed drops drastically and you have to wait for better speed. But with ILL you don't have to wait for the bandwidth availability. You will get dedicated bandwidth all along.

2. SLAs and Uptime:  ILL services are backed with Service Level Agreements.  In this agreement, the provider commits to providing the dedicated and symmetrical bandwidth. Any interruption in services will be fixed within few hours, approx. ETR is 04 Hrs. ILL service is more scalable because it promises to provide higher uptime, low latency, and low jitters. In broadband internet Service provider is not committed to providing the above services. Broadband users will get what will be available at the provider node. No SLAs in broadband connection make it unreliable.

So, ILL service differs from Broadband in terms of its dedicated and symmetric speed and SLAs. These features make ILL more reliable because your provider has signed an agreement with you to provide the promised services.

Disadvantage: ILL  is costly as compare to Broadband Internet connection. In ILL connection Internet Service Provider (ISP) have to provide you a separate dedicated line for you, which somehow costs you too. Monthly or Yearly subscription plans are costly as compare to Broadband plans.
