Determining How Much Bandwidth an ISP Needs and How Many Users it Can Lease To

o determine how a lot bandwidth an ISP requires to offer customers with a set bandwidth, you could do a little division with a calculator.

To determine the suitable variety of customers that an ISP can lease its bandwidth to, you need to know two things: the total bandwidth out there (the SUM of all of their connections) in addition to the marketed speed allotted to the end user. To determine the variety of customers, you'll divide (utilizing the same units) the total out there bandwidth by the bandwidth allocated to each user.

For instance, utilizing your determine, say a small ISP is sub-leasing a T1 line to DSL subscribers, and they promote that their clients may have 128kbps speeds. A T1 line is rated at 1.544 megabits per second. This is equal to 1544.0Kbps. So we divide:

1544kbps / 128kbps = 12.06, which rounded down could be equal to bandwidth out there for 12 (twelve) - 128kbps users.

The first quantity must be the SUM of the ISPs strains, as a result of usually an ISP may have quite a lot of massive strains that they use as spine connectors; i.e., 6 (six) - OC3 lines.

The above instance is for a small-scale ISP, however you get the concept how these volumes are calculated. Giant ISPs need gigabits price of obtainable bandwidth, and have hundreds of hundreds of users. The amount of cash the bigger strains value will be staggering, some in extra of $one hundred,000 a month.

ISPs could enable more customers on their networks than they actually have assist for, which most likely happens fairly steadily, besides as long as everyone would not start closely utilizing their connections at once, it would not cause too many problems.

This article isn't an all-encompassing discussion on the elements figuring out the quantity of bandwidth an ISP needs or how many customers it could assist, however merely a "scratching of the floor" have a look at what to think about when calculating these amounts.
