WebSocketin

WebSocketin is a term used to describe a hypothetical evolution of the WebSocket protocol intended to improve real-time, bidirectional communication between clients and servers. It is not an official standard, and no formal specification has been published by standards bodies. In discussions and educational materials, WebSocketin is presented as a concept rather than an implemented technology.

Conceptually, WebSocketin would extend WebSocket by introducing multiplexed channels over a single connection, allowing multiple logical streams to share the same underlying TCP connection. It would aim to reduce handshake and connection overhead for applications that require many simultaneous real-time links, such as collaborative editors or live dashboards. It could also provide enhanced framing and subprotocol negotiation, enabling richer message routing and automatic fallbacks.

Implementation and adoption: There are no widely deployed implementations of WebSocketin. Some researchers and hobby projects have prototyped ideas similar to multiplexing or multi-channel real-time protocols, but these are not standardized or interoperable with standard WebSockets. Compatibility with existing WebSocket servers and clients is a consideration in any proposal.

Security and interoperability: Any proposal would need to address per-channel authorization, cross-origin access, and buffering strategies to avoid head-of-line blocking and ensure predictable performance. Since WebSocketin is not standardized, interoperability with current WebSocket clients requires adapters or dual-stack support.
