In a customer-hosted runtime plane, which method allows nodes to automatically detect each other?

In a customer-hosted runtime plane, nodes can automatically detect one another through multicast communication. This method allows a single packet to be sent to multiple destinations simultaneously, which is particularly effective in scenarios where nodes need to discover each other without requiring a dedicated address for each connection.

With multicast, a node sends out a message to a specific multicast group address, and all other nodes that are part of that group can receive the message and respond accordingly. This significantly simplifies the discovery process as opposed to methods like unicast, which involves sending messages to specific nodes one at a time, or broadcast, which sends messages to all devices within the network but can lead to excessive network congestion.

Utilizing multicast enhances scalability and efficiency by allowing nodes to communicate and collaborate without overwhelming the network with too many broadcast messages or requiring a comprehensive list for addressing each node individually.
