A few years ago, we watched television from a sofa, viewed films on a DVD, listened to music or the radio over a hifi system or the car radio, and read the news in a newspaper.
Today we watch TV and listen to the radio via Web streaming, we publish our personal videos on our preferred social network, and watch videos on YouTube.
While file compression techniques have improved considerably, bandwidth usage continues to increase—along with its price.
This type of Internet usage requires extensive bandwidth, often at the expense of business applications, because the network is saturated by these bandwidth-hungry applications—which are often for private use.
Confronted with this over-consumption of bandwidth, many businesses initially tried to increase their bandwidth capacity. Today there is a real craze for proxy cache QoS solutions.
This first level is effective if it allows to limit bandwidth for sites and site categories which have been specifically recognized as non-professional. Filtering is also vital for optimizing streams in order to ensure that priority bandwidth is available for business applications.
Yet with the growing presence of businesses on sites and Web 2.0 media, the filtering tool must also enable users to have specific rights to 2.0 platforms, based on their position.
Likewise, for videos, the tool must be able to filter out certain sites (e.g. YouTube) but allow access to professional videos according to the user's profile.
By adopting this philosophy, businesses can reap the benefits of the Internet while protecting their network performance.
