CacheFlow typically demonstrates a 40% savings on general web traffic, while savings with dedicated content caching deployment scan approach 90%. This translates into a rapid return on investment and significant long-term cost savings for service providers on international bandwidth, and reduces backhaul traffic on domestic links. By better conserving and optimizing bandwidth with caching, customers are better positioned to serve more users, deliver enhanced next generation services and better leverage existing network investments without costly upgrades.
