How to Design a Highly Available URL Shortening Service

To design a url shortening service that is highly available, you need to follow a few important steps. Those steps include: Creating a unique, short URL that is not easy to copy and paste, tracking clicks, and a 16-bit CRC. To get started, you can follow the steps below:

Create a url shortening service

Whether you’re looking for an alternative to Google’s URL ย่อลิงค์ service, or you want to create your own, it’s important to consider several factors when choosing a provider. First of all, a URL shortening service should be highly available, scalable, and fault-tolerant. It should be able to process millions of requests per second. Another key element is a good security record.

The ability to track analytics is also a great benefit of using a URL shortening service. These services offer various analytics tracking tools, such as link clicks, as well as link length. Many URL shortening services also allow users to provide their own custom domains. This feature allows businesses to track how many visitors click on a certain URL and how often they visit it.

Has a distinct short URL

A short URL is useful if you use it once and then need to access a website again. In addition, a short URL can be used more than once, and statistics are stored in the URL’s history. The US patent application process makes patents public within 18 months of being filed. These statistics can be useful to businesses and marketers. However, it is important to remember that short URLs aren’t a permanent solution.

You may wonder how to track the number of times your shortened URL is clicked. One way to track your website’s performance is to track the number of visitors to specific pages or links. Shortened URLs are easier to remember and fit better into messages. But there are two risks. First, they can reveal information about your visitors’ location, browser, operating system, and social media channel.

Services to determine

URL เว็บย่อลิงค์ services offer several features, including link tracking. This feature allows you to monitor how many people have clicked on your links and how many of those people shared them. Depending on your purpose, URL trackers can also help you determine which demographic groups your marketing efforts are most effective. You can even use these services to determine which ad campaigns work best for certain demographic groups.

What is the difference between a 1-Wire and a 16-bit CRC? In short, the CRC-bit is one byte of the registration number. Its primary Short URL function is to ensure the integrity of data communication. The CRC-byte is generated in the hardware of select 1-Wire devices. If the two CRC-bytes are the same, the resulting hex value will be 0000.

Operation to calculate it

A 16-bit CRC starts with a non-zero initial value, so the leading zero bits have no effect on the CRC value. The 16-bit CRC doesn’t require an additional XOR operation, unlike the CRC32, which requires an additional XOR operation to calculate it. Furthermore, a 16-bit CRC can be calculated faster than a 32-bit CRC and requires less space than a 32-bit one. Its long length is sufficient for data that is less than a few thousand bytes.


The difference between a 16-bit and a 32-bit CRC is the oddness of the polynomial used to calculate the value. In a 16-bit CRC, the highest degree of the polynomial is represented by n+1 bits, whereas the remainder of the polynomial is represented by only one bit. This makes the CRC value the same as the original value, with the same odds.
