Edge caching in an enterprise context caches inside your own network, on servers at the edge of your WAN. A CDN reduces the distance from origin to your building; an enterprise edge cache eliminates duplicate traffic within it. Large organizations typically use both." } }, { "@type": "Question", "name": "What is an enterprise content delivery network (eCDN)?", "acceptedAnswer": { "@type": "Answer", "text": "An eCDN is a content delivery network built for private corporate networks rather than the public internet. It uses techniques such as edge caching, peer-to-peer distribution and multicast to deliver video to large internal audiences without saturating WAN links. Vbrick Universal eCDN combines all three." } }, { "@type": "Question", "name": "Do I need edge caching if I already have a CDN?", "acceptedAnswer": { "@type": "Answer", "text": "Usually yes, if you broadcast to large numbers of employees in shared offices. A CDN delivers one copy to the edge of your network; without an eCDN, that copy is then duplicated once per viewer across your internal links. Edge caching is what stops that duplication." } }, { "@type": "Question", "name": "What does it take to deploy Vbrick Edge Caching?", "acceptedAnswer": { "@type": "Answer", "text": "It is software-only and installs on existing servers at each location, with a one-time setup and no dedicated hardware. Caches are then managed centrally from a cloud console." } }, { "@type": "Question", "name": "How does edge caching differ from peer-to-peer and multicast?", "acceptedAnswer": { "@type": "Answer", "text": "Edge caching stores video on a server at each location. Peer-to-peer distributes fragments between viewer devices with no server required. Multicast sends a single stream that the network replicates to many viewers. Each fits a different network topology, which is why Vbrick Universal eCDN offers all three and lets you combine them." } } ] }
