ADOBE CONNECT 6.0

Technical Overview

Lowered demand on the origin Enterprise Server cluster when edge servers are deployed. Connection aggregation occurs on a per meeting basis;

in this figure, all users at the edge are attending the same meeting.

Data flow

Connect Edge Server is designed to allocate and balance access to an Enterprise Server by using the existing

bandwidth resources more efficiently. After the edge servers are deployed, users access Enterprise Server through

their configured edge server. Edge servers forward authentication requests to Enterprise Server, but after they are

authorized and if the data requested is found in the edge server’s cache, the edge server returns the cached meeting

or training content data to the requesting client (the user’s computer) without calling on Enterprise Server. This

detour to Enterprise Server is transparent to users. In this scenario, aside from authentication, no additional

demands are placed on the origin Enterprise Server servers.

If the requested data is not found in the edge server’s cache, the edge server forwards the client’s request to the origin

servers, where the user is authenticated and the request for services is authorized. The origin servers return the

results to the requesting edge server, which in turn delivers the results to the requesting client. The edge server also

stores this information in its cache, where other authenticated users can access it. In this scenario, fewer requests for

services are forwarded to the origin servers.

An edge server is configured to intercept the requests for Enterprise Server services from a particular zone. The

Connect Edge Server then collects or aggregates these requests, and transmits them to the origin Enterprise Server

servers (see the following example for data flow with edge servers). The origin server returns the results to the edge

server, which forwards the data to the user’s client computer.

Sample scenario

A networked Enterprise Server deployment might have multiple edge servers installed. For example, one edge server

might aggregate and forward requests from San Francisco and another might aggregate and forward requests from

Chicago. Each edge server then performs the following steps:

• Gathers the requests from its clients for each meeting and forwards them to the origin servers located in the data

center in Chicago.

• Receives the responses from the origin.
