Give your WAN a boost

摘要

Optimizing WAN links can reduce telco charges in either of two ways. For mature links with fairly steady usage (neither growing nor shrinking), you can use WAN optimization devices to compress the data and then tell your telco to dial back the bandwidth you're leasing.You pay less for the link, yet the same information flows through it. For links with rapidly increasing bandwidth usage that you plan to upgrade soon,WAN optimization devices can compress the data and thus let you defer the upgrade to a much later date. A WAN link that was near maximum capacity suddenly can handle present and future traffic with ease.
