Enjoy another issue of NetEqualizer News! This month, we continue our conversation on YouTube Caching, with articles on why you should consider Caching and how to measure its effectiveness. We also give you the Facts on QoS, in this month’s Best of Blog article. Finally, we clue you in on the upcoming edAccess Conference, in case it is a fit for you!
As always, feel free to pass this along to others who might be interested in NetEqualizer News.
Since the release of YouTube caching support on our NetEqualizer bandwidth controller, we have been able to review several live systems in the field.
Below we will go over the basic hit rate of YouTube videos and explain in detail how this effects the user experience. The analysis below is based on an actual snapshot from a mid-sized state university, using a 64 Gigabyte cache, and with approximately 2000 students in residence.
The Squid Proxy server provides a wide range of statistics. You can easily spend hours examining them and become exhausted with MSOS, an acronym for “meaningless stat overload syndrome”. To save you some time we are going to look at just one stat from one report.
From the Squid Statistics Tab on the NetEqualizer, we selected the Cache Client List option. This report shows individual Cache stats for all clients on your network. At the very bottom is a summary report totaling all squid stats and hits for all clients.
This June 22nd, NetEqualizer will be attending the edAccess conference in Hightstown, New Jersey.
The edAccess Conference is geared to small schools and colleges, and was recommended to us by long-time customer Tom Phelan of The Peddie School.
The conference is unique in that it is limited to 100 attending schools, and the attendees define the topics to be discussed during the 1st sessions! If you are a small school or college and would like to attend, please register at edaccess.
We are always open to considering conferences to attend. If you know of a conference that you think would be a good fit for us, please email us atsaleswith your recommendation.
Why Consider the NetEqualizer Caching Option (NCO)?
Over the last several years, the volume of static, deterministic Internet traffic has grown by leaps and bounds, to the point where it may comprise 40% and up of your Internet traffic.
While behavior-based shaping on its own is a great solution for reducing congestion on your network, adding on caching is a complementary approach, and should be considered as part of your overall bandwidth management strategy, as caching reduces your overall Internet traffic volume.
In this white paper, we discuss the capabilities of our add-on module, the NetEqualizer Caching Option (NCO).
Usually in the first few minutes of talking to a potential customer, one of their requests will be something like “I want to give QoS (Quality of Service) to Video”, or “I want to give Quality of Service to our Blackboard application”.
The point that is often overlooked by resellers pushing QoS solutions, is that providing QoS for one type of traffic always involves taking bandwidth away from something else.
The network hacks understand this, but for those that are not down in the trenches
sometimes we must gently walk them through a scenario.
