We’re often asked what the specific requirements are for a company or individual to present on or attend a live WorkCast event. Here’s the low-down on all things technical.
Not using a proxy server/VPN is recommended
Why?
-
VPNs are typically not designed or configured to support real-time media.
-
Connectivity to WorkCast might not be efficient due to hair-pinning traffic through a VPN device.
When it comes to WorkCast traffic over proxies, we recommend bypassing proxies. Proxies don't make WorkCast Studio more secure because the traffic is already encrypted.
And having a proxy can cause issues. Performance-related problems can be introduced to the environment through latency and packet loss. Issues such as these will result in a negative experience in such WorkCast Studio scenarios as audio and video, where real-time streams are essential.
Some organisations have no option to bypass a proxy for WorkCast traffic. If that's the case for you, the problems mentioned above need to be kept in mind.
We also strongly recommends:
- Using direct UDP based routing
- Allowing UDP traffic
For attendees and presenters there are no WorkCast downloads or plugins required.
