They say you can’t squeeze blood out of a turnip. And if you could, why would you? However, you can squeeze more bandwidth into your network. And by doing so, you can support more users and applications, and gain more throughput for faster delivery of applications.
With the abundance of IP-enabled devices and converged networks, new and expanding business opportunities are opening up using innovative business and consumer applications. That’s the good news. Unfortunately, these opportunities are producing ever-increasing demands on network bandwidth.
With the increasing stress on network resources, IT administrators are looking to WAN optimization solutions to gain back valuable lost bandwidth consumed by bandwidth-hungry applications and inefficient network protocols. WAN optimization solutions are key technologies that solve bandwidth problems, and allow network administrators to flexibly scale networks to provide faster responses to users requesting applications and content.
Squeezing more bandwidth into your network is done using data reduction technologies that dramatically improve bandwidth utilization and user response times. By reducing the amount of data sent over the network, more applications and users can be supported with existing bandwidth.
WAN optimization techniques both fill the network link, and optimize traffic throughput by reducing the amount of unnecessary data sent over the WAN, reducing the number of TCP and application turns (handshakes) required to complete a transaction, and eliminating packet re-transmissions due to dropped or out-of-order packets.
The idiom that says, “You can’t squeeze blood out of a turnip”, reminds us that you can’t get something from a person, or object, that they don’t possess. But, within networks, although you can’t get more bandwidth than you paid for, you can reclaim lost bandwidth unnecessarily consumed by applications and inefficient technologies, and hence, you actually get what you paid for by fully using the available bandwidth.
