The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

WAN acceleration
Tags: WAN, acceleration, open source, bandwidth

There exist several WAN acceleration devices, like Riverbed Steelhead appliances, that reduce WAN traffic through various compression and data reduction techniques. These devices all have in common that they are very expensive, too expensive to make a business case compared to just upgrading WAN bandwidth.

I was wondering if there are any open source based solutions that do WAN acceleration ?

Well there are some, but for limited functions.  Example, if all you want to compress is HTML data from Web sites you can use Apache as a proxy server with gzip/deflate.

However, you really need to look at the costs.  We have looked at them and they are typically much cheaper than upgrading bandwidth.  Remember these devices are designed to be used over private WAN link, not the public Internet.   Private links are very expensive, in the range of 2-5 times what a Internet connection may cost, but they provide guaranteed througput, where as the Internet is not guaranteed.

Are you looking at this for things like File and Print Sharing and non-Web based applications or just Web based applications.

>We have looked at them and they are typically much cheaper than upgrading bandwidth.

This is not so in our case. We use a 10Mbit fiber connection and the cost of a pair of Riverbed boxes is 5 times higher than the yearly cost of upgrading this connection to 20Mbit.

We're using this connection for offsite data replication & backup.

Which models where you looking at?  IIRC to support 10Mbps of raw throughput it would cost about $40K for a pair and I would think that the cost of difference between a site-to-site 10 and 20 Mbps connection would be more than $8K a year, that is less than $700 a month for a 10Mbps bump up. Unless, of course, you get a real good deal or the two sites are fairly close to each other.

For data replication there is not a whole lot you can do, as you would need transparent data compression inline.  However for backups, there are a few options such as "PKZip" type products or products that are "client/server" type backups that support data compressions, such as IBM's Tivoli Storage Manager (TSM).
