Cisco Content Engines accelerate content delivery for end-users by transparently caching frequently accessed content and then locally fulfilling content requests rather than traversing the Internet/intranet to a distant server farm. This solution helps to protect your network from uncontrollable bottlenecks and accelerate the delivery of content, enabling service providers to offer higher service quality and enabling enterprise employees to be more productive. All used and refurbished Cisco Content Engines are rigorously inspected and tested to ensure quality and performance like new equipment.
