Accelerate validation of Google Meet eCDN configuration at scale with Silent Test Mode
What’s changing
We are introducing Silent Test mode, a new offering that lets you run a large-scale eCDN (Enterprise Content Delivery Network) test with your users and devices, across your entire network, while minimizing any risk of impacting the viewer experience.
Google Meet eCDN provides peer-assisted media delivery for Meet live streams, saving up to 95% of the original bandwidth. To optimize bandwidth savings, administrators may want to fine-tune peering policies and custom rules to match their network topology. Silent Test is a risk-minimizing mode that helps admins validate those configurations by running large-scale eCDN tests with real user profiles and devices across large or global networks.
When Silent Test mode is turned on, Meet eCDN will run in a full simulation mode during large meetings and live streams. Live stream clients collect and report real-world data and statistics on how peer-based delivery through eCDN would perform, while showing viewers media that is directly served from Google's servers. This allows admins to quickly and with low risk test various configuration options.
In Silent Test mode clients will:
- Stream media directly from Google's servers and use it for viewer playback
- Discover and connect to peers to form Peering Groups
- Operate in their client role (Root, Leaf or Branch) in a full P2P topology
- Exchange actual media for simulation purposes and to generate real-world network load
- Report back any connectivity bandwidth issues between peers
- Collect all statistics in Meet Quality Tool and clearly mark metrics from Silent Tests
Advanced operation
In addition to simulating eCDN for regular live streams administrators can now also perform large-scale network tests by scheduling* workload scripts on users' devices to run transparently in the background. Since no live stream needs to be arranged for actual users to join, those tests can run as often as needed or use non-peak hours. This is a powerful way for admins to faster validate iterative changes.
*Using an existing endpoint management system that allows remote script execution.
