Squid webcache

If you were to create a webcache, that could be optionally accessed by customers from their browser settings, you could probably reduce external bandwidth and speed-up web surfing.

Squid webcache

Hi,

Unfortunatly, a web-cache service doesn't solve the problem in the slightest.

External bandiwdth costs are relativly low cost, compared to the BT Central bandwidth.

When a customers transfers data from a clean-feed or via a web-cache, the data will still need to be transfered accross the central pipes.

There is unfortunatly no way to avoid this process.

Squid webcache

There are two very good reasons why a web cache will not help in any way with the bandwidth problems:

1) A diagram:

User <-> BT network <-> PN BT central pipes <-> webcache -> the Internet

The bit in bold is where the bandwidth bottleneck is. So you can see, having a webcache makes 0 diference to the bandwidth on the BT centrals. i.e. it makes no difference where the data comes from (webcache or outside world), it still has to go through the BT centrals to get to you. All the webcache does is help reduce the traffic between the rest of the internet and the Plusnet Network and that is one area where there is no bottleneck in terms of traffic due to there being many multiple redundant gigabit connections to the main peering companies in Docklands.

2) PN have been there, it made a mess of the whole system with frequent out of date pages (especially when updating PN websites), slow loading times and frequent timeouts, so it was canned. And yes, they were using squid.

I hope they don't try anything like it again.

That wasn't quite the same thing AFAICT.
