Although this figure shows only three subscribers or proxies per distributor or proxy, up to 40 subscribers can be serviced by one distributor or proxy. Therefore, if you were to hook up 40 proxies to a distributor and connect 40 servers to each proxy, you would be able to reach 1600 servers from one distributor. The inclusion of proxies also decreases traffic across WAN links. If the distributor had to send a 340MB database to each of the 13 remote servers, it would need to send more than 4.4GB across the WAN link. Distributions and Channels Figure 3 illustrates the method by which TED organizes and distributes data.
Distributions contain file grouping or SSPs.
The distributions are assigned to one or more channels to which subscribers subscribe. Likewise, the distributions are TV programs broadcast on each channel, and the TV viewers are subscribing servers. However, unlike a TV viewer, a ZFS subscriber can receive content from multiple channels at once. It ZFS integrates with eDirectory, the most mature and scalable directory in the industry. ZFS leverages your eDirectory tree structure to facilitate distribution assignments.
