What is Akamai Netsession Interface?

What is Akamai Netsession Interface Client

Akamai Technologies is a very popular content delivery network used by large websites and popular software applications like Microsoft Azure, IBM, HP and even NASA.

An internet software, NetSession interface is particularly designed for the sole purpose to deliver faster and more reliable applications, data and media downloads. Not only it improves the overall efficiency and speed of the demanding downloads but also aids the system to have considerably good streams over the internet.

It has been reported that NetSession Interface is being used by many software and popular media publishers to deliver files and streams to the public. The application is helping the companies and the customers to get more downloads done in no time.

Slower download speeds are certain to piss one off, and this is where the NetSession Interface comes into rescue. It basically helps you to get faster access to the company resources which you are after, by using the nearest Akamai servers. What it primarily does is, it reduces the load on the client-server by mirroring their content on Akamai servers that in turn enables the users to get access to the content faster.

For instance, if you are running a video streaming site that is having the central servers located in New York, but your users are distributed all across the globe. So, how will you reach out to them with faster and reliable services?

In such cases, the Akamai NetSession Interface mirror the demanded content from the primary server to its local server to have the users get their hands without waiting for too long.

Now, before you may ponder, if NetSession Interface has any bad effect on your system resources, here you got our insight:

Since the Akamai NetSession Interface is a background application that tends to reside on the computer, therefore, it has a small impact that is almost negligible on your memory or CPU capacity.

Furthermore, if you are making use of any services or software using the NetSession Interface feature and you have it enabled, then it may also use a small amount of your upload bandwidth facilitating other users of NetSession Interface to download pieces of the publisher’s content from your computer.

The prime purpose of Akamai is to serve their client’s data by mirroring their content on Akamai servers and reducing the load on client servers. Many web busy companies use Akamai to off-load their hardware work and provide data to the user from the nearest host.

For Example: If you run a site like YouTube, you would require lot of storage hardware & best Internet connectivity. If your company is based in New York and you have users browsing your site from Asia, you need to have a local server in Asia to provide fast data delivery. This is what Akamai does, it will provide data to Asia users from their Asia servers so you don’t need to install new hardwares in Asia. You can also call Akamai as a Content Delivery Network (CDN).

The Working and Algorithm

If a person browsing a website from Hong Kong China, has downloaded all the files from the Akamai’s Singapore server, now serves as a local server to Hong kong users. How does this help you? This reduces the overall wait time. So, all of this helps in providing you faster access to resources from the Internet.

The entire Akamai network algorithm works on calculating the nearest server location and upload speed of that server. This calculations help to provide the users with fast download speeds by reducing the wait time. In this calculations, sometimes a user’s PC which has the resources already download and provides good upload speed is used as a server to provide to the requesting users locally.

While you might be wondering how this program got installed on your computer, you’ll be shocked to see the customer list of Akamai Technologies as it includes many big brands like Microsoft, Adobe, Best Buy, American Idol, Audi and many more.

Why Akamai is running on your computer?

Akamai Netsession also allows other users of the NetSession Interface to download pieces of the publisher’s content from your computer. It does this by constantly monitoring your network use, and sending this information to the Akamai Server. 

The reason for file sharing going on between clients is that those common files (which are downloaded anyway, even if Akamai wasn’t in the background) are always common to a particular web presence – such as fixed banners and company logos.

According to Akamai,

NetSession can also use a small amount of your upload bandwidth to enable other users of the NetSession Interface to download pieces of the publisher’s content from your computer. The NetSession Interface runs in the background and uses a negligible amount of your computer resources or upload bandwidth when you are not actively downloading content.

Whether Akamai Netsession is safe?

Akamai Netsession doesn’t store or transfer any of your personal data. Only the company files are transferred whenever a user requests any resource from the company. Its main purpose is to improve speed, reliability, and efficiency for downloads and streams. Also, Akamai NetSession Interface only downloads or streams content to you only after you have requested it from your software or media publisher’s interface.

While there’s no loss of resources, at some situations users have reported very high CPU and bandwidth usage with over 2-3GB of data being uploaded from their computer. Many of the users are completely unaware of their system is being used as a local host for resources to server some company’s data. Also Akamai does admit

There have been some cases in which a particular busy computer with high bandwidth usage has experienced reduced download performance.

Akamai is safe

While installing, Akamai doesn’t ask the user about using the computer as a local host of resources. But there are chances of you using someone else’s computer as a host to get data more quickly. Overall it’s an ecosystem which works on give and take basis.

So, if Akamai Netsession safe? Yes, it’s completely safe. But if you’re facing any issues like slow Internet speed, high CPU usage or anything else, you can disable the Netsession Interface. But, the softwares of the companies you have been using, might not work as expected and the softwares would request you to enable Netsession interface for proper functioning.
