302 content routing
HTTP Content Routing.
astats (stats_over_http)
An ATS plugin that allows you to monitor vitals of the ATS server. See Cache Monitoring.
A caching proxy server. See Caching Proxies.
A group of caches that together create a combined larger cache using consistent hashing. See Cache Group.
consistent hashing
See the Wikipedia article; Traffic Control uses consistent hashing when using HTTP Content Routing for the edge tier and when selecting parents in the mid tier.
content routing
Directing clients (or client systems) to a particular location or device in a location for optimal delivery of content See also HTTP Content Routing and DNS Content Routing.
coverage zone map
The coverage zone map (czm) or coverage zone file (zcf) is a file that maps network prefixes to cachegroups. See Localization.
delivery service
A grouping of content in the CDN, usually a determined by the URL hostname. See Delivery Service.
edge (tier or cache)
Closest to the client or end-user. The edge tier is the tier that serves the client, edge caches are caches in the edge tier. In a Traffic Control CDN the basic function of the edge cache is that of a Reverse Proxy. See also Cache Group.
(traffic ops) extension
Using extensions, Traffic Ops be extended to use proprietary checks or monitoring sources. See Traffic Ops Extension.
forward proxy
A proxy that works that acts like it is the client to the origin. See Forward Proxy.
geo localization or geo routing
Localizing clients to the nearest caches using a geo database like the one from Maxmind.
health protocol
The protocol to monitor the health of all the caches. See Health Protocol.
Finding location on the network, or on planet earth. See Localization.
mid (tier or cache)
The tier above the edge tier. The mid tier does not directly serves the end-user and is used as an additional layer between the edge and the origin. In a Traffic Control CDN the basic function of the mid cache is that of a Forward Proxy. See also Cache Group.
The source of content for the CDN. Usually a redundant HTTP/1.1 webserver.
parent (cache or cachegroup)
The (group of) cache(s) in the higher tier. See Cache Group.
A group of settings (parameters) that will be applied to a server. See Profile.
reverse proxy
A proxy that acts like it is the origin to the client. See Reverse Proxy.
