ADOBE CONNECT 6.0

Technical Overview

The Connect Enterprise application server is stateless and follows a service-oriented architecture (SOA). Because the

application server is stateless, scaling is near-linear. The transactional and application metadata that the application

server manages can be stored in either single or multiple replicated SQL databases.

Meeting server

Enterprise Server includes an embedded instance of Macromedia® Flash® Media Server from Adobe. In the context

of Connect Enterprise, Flash Media Server is referred to as the meeting server. This component handles all of the real-

time streaming of audio, video, synchronization of data, and delivery of rich-media content, including Acrobat

Connect Professional meeting interactions.

Flash Media Server streams audio, video, and accompanying meeting data using the Adobe Real-Time Messaging

Protocol (RTMP). Flash Media Server can also act as a proxy to route internal system HTTP traffic in a single-server

or software-based SSL configuration.

Some Flash Media Server tasks include meeting recording and playback, timing the synchronization of audio and

video, and transcoding—converting and packaging data for real-time screen sharing and interaction. Flash Media

Server also plays a vital role in reducing server load and latency by caching frequently accessed streams and shared

data.

Flash Media Server and Connect Enterprise application server components work together on the same computer to

deliver the Connect Enterprise solution.

Database

The Enterprise Server database is used for persistent storage of transactional and application metadata, including

user, group, content, and reporting information.

Enterprise Server can use either the embedded database engine (MSDE) or the full version of Microsoft SQL Server

2000 or Microsoft SQL Server 2005. The embedded database engine is included with Enterprise Server and must be

installed on the same computer as Enterprise Server. SQL Server can reside on the same computer Enterprise Server,

or you can deploy it on a different computer or in a cluster (a configuration with multiple computers) for scalability

and redundancy.

When Enterprise Server is deployed in a cluster, or with multiprocessor computers with Hyper-Threading

Technology (HTT), you must use SQL Server and it cannot be installed on the same computer as Enterprise Server.

Data flow

Enterprise Server uses the following communication protocols: HTTP, HTTPS, RTMP, and RTMPS. Adobe’s Real-

Time Messaging Protocol (RTMP) is optimized to deliver real-time, high-impact streams. RTMPS is the secure

implementation of RTMP.
