Connect & Unified Voice (UV) Traffic Flow Diagram

Issue: Plan for the flow of traffic to enable UV among the various components in any Connect deployment: Connect, Flash Media Gateway (FMG), Session Initiation Protocol (SIP)

There are numerous documents on the topic of Unified Voice (UV) with Connect:

This diagram shows the flow of traffic and the protocols used for UV with Connect and is offered as a planning and a troubleshooting tool; click on the diagram to expand it for viewing:

The Adobe Connect Deployment Guide on the F5 Website needs Updating

Issue: Be careful when following the Adobe Connect Deployment Guide posted on the F5 Website. While the article is be helpful, there are some ambiguities that can lead to trouble. I have tried to update their deployment guide but have not succeeded; the LTM is the most popular load-balancing device and SSL accelerator in the Connect niche and when it is set up properly it works splendidly. Here are corrections, updates and things to watch out for when deploying Connect behind an LTM:

1. Do not use an HTTP profile for an RTMP VIP. An HTTP profile for RTMP VIPs may affect playback of video as well as break remote Edge connectivity. Remember that you have two servers running on each box, a Tomcat application server and an FMS server. Do not treat the FMS server as though it were an application server; RTMP is a streaming protocol that requires a TCP profile at the HLD VIP.

2. Use the health monitor documented here for LTM.

3. Do not use session-awareness or stick-sessions even if you use SSL. The Round Robin algorithm should float freely to the Tomcat application pool.

4. Do not use Nagle’s Algorithm with SSL; it will have a negative effect on performance.

Adobe Connect Servers and Hardware-based Load-balancing Devices

This updated article offers a best-practice configuration of a basic Connect pool/cluster behind a high-end, application-aware HLD such as F5 BIG-IP LTM. This article does not discuss SSL-acceleration. This article does not describe all the possible configurations, but offers a general working example of a basic HTML/RTMP non-SSL cluster/pool of Connect servers.

What Camera should I use in my Connect Meeting?

Issue: Many customers ask Adobe what camera to use with Connect

The short answer is, most any camera you would like. Adobe does not recommend specific cameras but we do have this posted for guidance:  Peters’ Camera Options Recordinghttps://my.adobeconnect.com/p11223582/?launcher=false&fcsContent=true&pbMode=normal

 

Clustering Adobe Connect Servers with Microsoft Network Load Balancing

Many software-based server load-balancing and fail-over options have prematurely reached the end of the product life cycle. The market prediction that effectively swept software-based options off the enterprise landscape was that the price of superior hardware-based solutions would decrease enough to make the software options superfluous. The problem with this prediction is obvious to anyone who has tried to cluster a small pool of application servers on a tight budget: the price of the hardware options that are worth having have not dropped enough to fill the niche occupied by software clustering applications….

Accessing and Editing Adobe Connect Recordings

When most people think of meeting recordings, they often expect a standard video capture of the original meeting. For most web conferencing platforms, this is the case. Adobe Connect recordings however provide much more functionality. It’s certainly possible to generate a static video by clicking the ‘Make Offline’ button. By default however, Adobe Connect recordings are much more interactive and completely indexed….

Adobe Connect server pools/clusters and hardware-based load-balancing devices with SSL acceleration

The most robust means of implementing secure socket layer (SSL) with Adobe Connect servers is through a hardware-based SSL accelerator and similarly, the most robust means of clustering Connect servers is with a hardware-based load-balancing device (HLD). Since all enterprise-class HLDs are also SSL accelerators (any that are not both are either legacy or low-end by definition), this example-based article offers a best-practice configuration of a Connect Server pool or cluster running Connect Meetings, Adobe Presenter on-demand content, Adobe Connect Training, Curriculum and Virtual Classrooms securely behind a high-end, application-aware HLD and SSL acceleration device such as F5 BIG-IP LTM. This article does not exhaust the possible configurations, but offers a general working example.
