Google ramps up plans for Edge Caching
Tuesday, December 16th, 2008
With the ever increasing traffic volumes generated by users with a thirst for video and other content increasing exponentially, Google has for some time now been investigating and implementing many technologies and solutions to ensure that it’s own content is delivered in the most efficient manner possible.
You may already be aware of Google’s significant investment in the Unity cable, which will join the US to Japan in order to meet increasing bandwidth demands. Google is now looking at going beyond just expanding and enlarging the Internet pipes, to bringing content closer to end users. This is what is known as Edge Caching.
Under this implementation, Google intends to house servers within the infrastructure of Internet Service Providers, therefore bringing content closer to end users. With the content closer to end users Google can improve the service it provides on sites such as Youtube. Why serve content to users in New Zealanders from the United States when you can push content to them through a local New Zealand server.
Opponents would complain that this ‘Edge Caching’ technique is going against net neutrality. I would disagree on this as in using this technique Google is not having traffic prioritized over competing traffic, but simply moving the content closer to it’s users. Of course with Google having closer relationships with Internet Service Providers it is not hard to guess what could arise from such an arrangement.
