Cisco Content Engines (CEs) accelerate any Hypertext Transfer Protocol (HTTP) deliverable and streaming media-type content by storing and delivering content close to end users on their local networks. The CE can reside in headquarters, branch offices, remote campuses, and international sites where WAN bandwidth is costly and scarce.CEs combine the benefits of pull caching and content delivery (content push) in an appliance solution that features unsurpassed network integration for ease of management, deployment, and access management. By building on the intelligence in the network and tightly integrating with Cisco routers and switches, content engines make it easy for organizations to cost-effectively deploy rich-media applications without compromising the integrity of the network.The Cisco Content Engine 7320 is a high-end Internet content delivery device that is installed on the WAN edge between your large enterprise or service provider network and the Internet. It is designed to handle OC-3 traffic at 155 Mbps speed.
