For the best experience, Adobe Connect requires suitable connectivity from each user to the server. Adobe Connect can accommodate different bandwidth levels such as modem, DSL, and LAN. But each type of connection requires a certain minimum for acceptable performance.
In addition to the throughput on any given type of connection, there are other factors that can affect the overall bandwidth of each connection. These factors include firewalls and proxy servers.
Adobe Connect presentations are normally delivered as HTTP data on port 80, while meeting audio and video streams are delivered as RTMP data on port 1935. When users are inside a corporate firewall that blocks these optimal ports, Adobe Connect uses fallback mechanisms to deliver RTMP data on ports 80 and 443. This fallback technology is called tunneling. This tunneling mechanism results in additional overhead that impacts overall throughput and the end user experience.
