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!

wingatesl:

It is really a question of what you are doing across this line. My main issue with a leased line is the service. You will always get finger pointing at who's fault something is and be without service for a while. With the public solution that outage usually affects a larger number of people and you are not the only one complaining. The internet based solutions usually yeild more bandwidth at a lower price, but you have no assurance of service. We have replace numerous "across town" T1s with 2 comcast and 2 verizon connections per side. We load share them and the users get around 4-5 Megs of bandwidth each way. I would never run a critical VPN connection over a single provider.

sabioit:

leased line is definitely better but much more expensive

Since VPN with have to over the internet using any ISP solution and they only provide you BEST EFFORT services

wingatesl:

To say definitely better is not accurate, it really depends on its use and locations. We have some clients with two sites in the same town running off comcast with increased bandwidth, 4 hour SLA, and 6ms ping times. The issue is they are not guaranteed, and will always require a backup.

techmp:

which is cost effective?
4 branch office with 40 clients each side with one head office need to trasfer data in each locations , which one is better . does leased line is dedicated permanat . still it goes through a telephone carrier .

wingatesl:

DMVPN is the winner in my mind for cost effectiveness. It is not the best option for Voice or Video (MPLS is) but is usable with extra latency

11.11.2007 at 09:15AM PST, ID: 20259665

techmp:

suppose it needs 1 mbps connected between offices , how much it costs , comparison of cost

reliabilty low means what ...vpn becomes problem
popular connection method for branch office connection is what

11.11.2007 at 09:21AM PST, ID: 20259694

wingatesl:

suppose it needs 1 mbps connected between offices , how much it costs , comparison of cost
The t1 and MPLS will have to be shopped in your area, but you can say $300 to $500 per side for public (internet VPN)and between $400 and $600 for private (point to point)

reliabilty low means what ...vpn becomes problem
The issue with the standard VPN is it is public, best effort, capable of doing down much more often than the other solutions.

popular connection method for branch office connection is what
DMVPN or MPLS are the most popluar these days (at least in this area)

11.11.2007 at 09:22AM PST, ID: 20259701

wingatesl:

As for costs of DMVPN you are looking at about $200 per side for high performance internet conections from two providers at each location

Accepted Solution

sabioit:

A T1 if you are in florida we can get you one for around 350 a month (www.sabioit.com) it is a reliable connection and it will accomplish what you need it still go trough the internet so you need to encrypt your traffic trough a VPN and encryption means speed performance

Now what i mean with leased line was a PPP which is much more expensive but is a single line directly from one branch to the other one there is no need to run a VPN or encrypt the traffic all your branch will be almost locally

PPP lines are for large enterprise you can go for the T1 if you are a small to medium business

If money is not an option, i would suggest looking into MPLS networks on leased lines.
You can also have a MPLS network based on DSL lines (cheaper).

Although the cheapest option VPN's on DSL lines are not consistent, i think the most value for money option is to have a MPLS network on DSL lines.
