Zoom Mesh is a native, zero-click, and zero-install client-based Mesh (eCDN) solution for Zoom Webinars and Events. The Zoom Mesh service minimizes network congestion for Webinars & Events while preserving the native Zoom attendee and host experience. Overall with Zoom Mesh, customers can take advantage of:

When multiple attendees and participants are connected to a Webinar from the same local network, this can put an unnecessary strain on the network due to the requirements for the incoming bandwidth to handle the webinar media streams from the Zoom Cloud to each webinar attendee. Zoom Mesh lowers this bandwidth using a number of clients to route media from the Zoom Cloud to the rest of the attendees within the network.
This is achieved via the service designating a number of Zoom Clients connected to a webinar as Mesh Parents. The parent clients send and receive media from the Zoom Cloud and distribute incoming streams to the other Zoom Clients (designated as Mesh Children) connected to the webinar within the same local network as the Parents.
Zoom Mesh features include:
In the normal Zoom Webinar and Events experience, all attendees joining the webinar or event from the same local network receive individual but identical streams from the host. If the attendees are for the most part working in the office this can cause a large strain, or even overwhelm an organization's WAN or internet connection, especially if the Host and attendees are in different offices or branches. To accommodate the bandwidth necessary to handle the streams, an organization would need to ensure the WAN or internet bandwidth is provisioned based on the potential maximum attendees in each branch or office in the organization.
With the Zoom Mesh architecture, only Zoom Clients designated by the Mesh service receive the stream from the Zoom Cloud. These designated hosts forward the media stream to the rest of the attendees within their LAN, greatly reducing the WAN or internet bandwidth necessary to stream to all attendees.

An important part of the Zoom Mesh is the survivability component. During an event or webinar, if a Mesh parent ends up losing connectivity, its children as well as the sublayer parents will automatically be distributed amongst the other active parents.
In the event that all Mesh parents are down, and there are no other clients that meet the requirements to be a parent, then all attendees will connect directly to the Zoom Cloud for the media streams.
