In just a few years’ time, the Internet has changed significantly. Starting as a hierarchical Tier-1, Tier-2 and Tier-3 topology, it is evolving more and more towards a mashup of directly interconnected networks, thus increasing its complexity both physically and logically. Driven by higher quality demands and lower transit network cost, content providers have been working on increasing the content to user speed by shortening the path, which positions the content as close to the consumer as possible. Content delivery networks (CDNs) started to develop enhanced algorithms to choose the “best” – or at least a better path – to the user in order to make the connection faster. Continue reading

Overcoming today’s network visibility limits

General, Products

In times of rapidly increasing internet traffic, it is becoming important for internet service providers (ISP) to seek more visibility and control over how and where content is entering its network, and how this can affect the user’s quality of experience.

Instead of facing rising infrastructure costs, let us help you get over the “best effort” principle and make content delivery and Quality of Experience (QoE) for your end users great.

We may venture to project some trends:
