Importance of Processor Speed on Originating Computer

[JJones]

I'm running a Connect Pro session on a older PC with a low processor speed. Everything seems to be working fine but I'm concerned that the low speed could affect the quality of my video. Can anyone offer advice on this? Is there a minimum system standard for maximizing video quality?

[Guest]

Video is streamed from the Adobe Connect server and not the host. The server has control of the streaming not the host machine. So when you upload a video the server takes it and runs with it irregardless of your machine.

So if our participants are seeing significant video artifacts and

occasional audio dropouts, are you saying that the problem is NOT with the

system hosting the event and generating the audio/video? If so, where is

the most likely source of the problem? Could we be bumping up against some

bandwidth threshold with Adobe that causes the video quality to degrade?

Yes, your network has to have the ability to handle the load of the meeting. Any kind of bandwidth contention at the local level or at the ISP will affect any web conference meeting regardless of vendor.

How far away are you from the server? If you are in a different country than the Connect server the long distance can cause network latency. It's best to use a server located on your continent. It's best to have a network that is designed properly and scaled to handle web conferencing. It's all a matter of bandwidth, firewalls, QoS, ISP quality, etc.

Thanks. I'll follow up with our network folk, but can you tell me if there

would be any bandwidth issues on the server side? Are there any conditions

under which the server would lower the video quality below that specified

by the room host?

Well..since I do not have your specifics on hand...it's hard to answer....

For on-premise customers the AC Server is on their LAN or in their DMZ and it depends on their ISP and network routers as to any bandwidth contention issues. Sometimes firewalls are a pain in the you know what if they are not properly maintained and programmed. I've seen "messes" when the IT folks have a team running Connect and another team running the firewalls and a third team running the network. All three groups want to kill each other and it's a mess. So, I recommend a joint effort whereby all three groups get on board and optimize web conference traffic. It takes some coordination to make sure the firewalls allow port 80, 443 and 1935 traffic 100% of the time and it takes someone to measure how much bandwidth is being consumed by email, file sharing, applications, and then Connect. A lot of times no one has taken a look in a long time and their LAN is way too undersized to handle large web conferences.

For Adobe hosted customers, it's important to make sure the same ports are always open for Connect traffic. Adobe hasoted servers are in the US in a couple places, UK and Japan. So, it would be best that customers make sure their accounts are on the right server for the continent they will be doing most of the hosting. Usually this works out great when customers get theoir accounts. But if you are located in Japan and you got your account a year ago then most likely you are using the US based servers. A new japan based server was added and customers would need to request their account be moved. That can affect/improve latency.

If you are using a partner server, then it all depends on their ISP and level of service.

Usually the bandwidth issue is not at the server side as Adobe has tons of servers that are optimized for fail-over and redundancy, They are scaled to rollover if a server gets too overloaded in the cluster.

I've sen university customers have bandwidth issues when students were using Netflix and completely overloading the network. Consequently, all services were affected like Connect. Traffic should be optimized to allow Connect a higher priority over email or Nteflix traffic.

Thanks for your thorough response. It was very helpful. I'd like to ask a

few brief follow-up questions if you don't mind.

Are all Connect Pro servers owned and operated by Adobe or are some owned

and operated by licensed vendors?

Does Connect Pro create a client/server stream with meeting attendees?

If so, does the server adjust the quality of the signal based on the speed

of the attendee's connection?

Thanks in advance!

Thanks. Great questions...all easy to answer!

1. Adobe Hosted uses Adobe servers in the US, UK and Japan and those are fully controlled by Adobe on Adobe facilities

2. Adobe Connect partners offer hosting services such as ConenctSolutions which has a US Government FISMA compliant facility (highly secure)...there are other partners as well depending on the country

3. Adobe Connect Managed Services is an Adobe Hosted via Amazon's AWS Cloud Service and allows you to run the server as a single tenant owner of the virtual server machine and it includes full redundancy and fail-over.

Yes, Adobe Connect is a client/server technology based on Adobe Flash Player (client) and the server includes Adobe Flash Media Server (FMS), Adobe Flash Media Gateway, App Server and others in the mix to handle security, authentication/LDAP, and audio integration. It uses port 1935 for Flash based (RTMP) streams of data very efficiently.

No, the host of a room controls the rate at which the stream is controlled. So, if the host reduces the bandwidth connection to DSL grade then it adjusts the stream fer everyone. It does not have the ability to detect each attendees network quality or condition (too much overhead would be needed to do that).

If you desire the AC Technical Guide I can send it. Just send me an email to hdrummon@adobe.com

I also have a computer but I try to install SSD on my personal computer which is good for my work. And it will increase the pc speed. So I have found some information from a facebook page. But I want to know more.
