What you should consider wan optimization solutions

Please note that this should take ISN bandwidth solutions, such as MPLS or Ethernet to say is. Instead of using Bandwidth question.
I would recommend seeing Wan optimization tools: the river bed, Juniper, Packeteer. In many cases, they work very well and latency, especially if the source of the problem is lax CIFS Wan-issue (copy / open / modify a file using Windows).
The first step in my opinion is to find your way using the IP packet. A delay could be caused if your relationship will be via satellite and not a land line (earthbound wireless, fiber-Underwater or country, etc.).
First I would recommend to track the package ..... and the decision of the SLA and the service provider to see if they can prove the quality of your desired parameters of BW, delay, etc. Matter
I will not jump them to buy or install anything before that!
Please note that all accelerators Wan-Latency solve the problem. Then choose a retailer that does not Wan-faster. But choosing the right is not easy. Wan-Depending on your traffic.
If you use applications (like Citrix, SAP) from priorizing traffic accelerators (as Packeteer or Ipanema) will give better results. However, if traffic from file-oriented (MS-Office) ..... than you will get better results and reduce the data Accelerators, such as rivers, Juniper and Cisco Citrix. In general, you ll probably get better results with the riverbed.
Wan Optimization devices only have the effect of TCP flows. If you have latency problems UDP flow (VoIP) I do not think you can do anything against it (real-time traffic is very sensitive to latency)
About the generic TCP flow optimization, you ll find plenty of sellers on the market to sell well according to your needs: Citrix WanScaler, AAS Cisco, Juniper, rivers, Expand, and probably many other vendors ...
Here is a trick to hide all the latency effect (they do not t hide the latency, because it was already there, hiding the effect), Wan optimization solution serves as a transparent TCP proxy, spoofing the IP address of the server to the client, spoofing the client IP address of the server, and send their messages Mack TCP in this country. So you do not wait t Mack round trip to the message. This helps to fill-the-pipe quickly. This is a solution to avoid the effects of latency, such as TCP throughput is very sensitive to latency, with a message back Mack, congestion control also has a terrible effect when the TCP connection starts.
They also apply selective Acks initial flow of the window to control the use of total link bandwidth Wan. Add to this compression mechanisms to artificially increase the available bandwidth, and approximately 7 layer optimization (especially for the CIFS file sharing, but also based HTTP compression), embedded QoS stuff, and you have a total of what we call the Wan optimization.
Whatever vendor you choose, all implement what I described above.
