Does OnSync support origin/edge? How will an origin/edge server deployment help me manage bandwidth?
Posted by Robert Strobl on 25 January 2013 11:12 AM

OnSync fully supports Adobe Flash Media Server's origin / edge capabilities. You can use these to optimise bandwidth usage in your deployment, scale your application, create a redundant set up and more. Adobe offers a lot of good information on their website which we recommend you read into.

This article will introduce you to some basics of bandwidth management and how an origin / edge deployment can help you adapt to bandwidth bottlenecks.

Since version 4.2.0 we support automatic IP detection for the customer to connect to the closest server. This is currently configured to work on a country level. We can help configure the origin edge setup once you know your exact requirements. 

The attached a diagram illustrates 4 Flash media servers in an origin/edge setup - 1 origin and 3 edges called S1, S2, S3

It shows a single OnSync session. In this session, 6 users are broadcasting 256Kbps video each. 1 is broadcasting from S1, 2 from S2 and 3 from S3. All users are receiving each others streams.

The diagram illustrates how the network handles traffic distribution and allows you to make decisions about network design and bandwidth allocation.

Note, each individual user has the exact same bandwidth requirement of upload 256kbps and download 5*256 = 1280kbps.

You will immediately see how an origin edge architecture will help you save bandwidth. It could make sense to put edges into LANs where several users connect, then connect each edge to the origin via dedicated bandwidth over the internet or an intranet.
