You are evaluating your WAN (Wide Area Network) and I wonder commentary can optimize performance across the network’ What are realistic options for a solution?
Note that this is not necessarily a solution for bandwidth, such as MPLS or ethernet say’ Rather, it is a matter of bandwidth usage’
I suggest looking for WAN optimization applications: Riverbed, Juniper, Packet’ In many cases, they do a very good job with the latency, especially if the main source of the problem is ignored issues CIFS WAN (copy / open / edit files using Windows)’
The first step, in my opinion, is finding the path IP packets take’ May cause a delay if your connection is via satellite and not a land line (Earthbound wireless, fiber or basement, etc)
First, I would say that the way of tracking packages ””’ then an SLA with your service provider and see if they can guarantee the quality you have in the configuration of biological weapons, delay, jitter, etc’
I will not jump into buying or installing anything before!
Note that all-latency WAN accelerators issues’ Therefore, choose a provider that has the WAN acceleration’ But the choice of law is not easy’ It depends on your WAN traffic’
If you use applications (like Citrix, SAP), an accelerator to prioritize traffic (or PACKET Ipanema) offers the best results’ However, if the traffic is directed to the file (MS-Office) ””’ you get the best results with the data reduction accelerators like Riverbed, Juniper and Cisco Citrix’ In general, it is likely to get better results with Riverbed’
Wan aircraft optimizations only affect the flow of TCP’ If you have any problems with the latency of UDP flows (VoIP) I do not think you can do something against this (real-time traffic is very sensitive to latency)
About the optimization of generic TCP streams, you will find many suppliers in the market for the sale of products that matches your needs: WanScaler Citrix, Cisco WAAS, Juniper, Riverbed, Expand, and probably many other suppliers ” ‘
Here’s the catch, they used to mask the effects of latency (not to hide the latency, because there are hidden effects), the WAN optimization solutions as a transparent TCP proxy, spoofing d ” IP address of the server to the client and the client IP spoofing and the server TCP Ack messages sent locally’ So you do not have to wait for the travel time back and forth to get the message ACK’ Enables you to ” fill the pipe fast’ This is a great solution to avoid the effects of latency, the performance of TCP is very sensitive to latency, because of the return Ack messages, including control of congestion has a terrible start when TCP connections’
Also apply selective ACK with large windows and the initial flow control using the total bandwidth of the WAN link’ Add to that the mechanisms of compression to artificially increase the available bandwidth, and some optimizations of the layer 7 (mainly for file sharing CIFS, HTTP, but also basa compression), QoS built things, and you have a vision of set of so-called “Wan optimization’
Whatever supplier you choose, all of them to implement what has been described previously’
