WebMUX

Here are some of the significant goals of the WebMUX protocol:
Simple design.

• High performance.
• Multiplexing—Multiple data streams (of arbitrary higher-level protocols) can be interleaved dynamically and efficiently over a single connection, without stalling data waiting for slow producers.
• Credit-based flow control—Data is produced and consumed at different rates, and senders and receivers have different amounts of memory and CPU resources available. WebMUX uses a “credit-based” flow-control scheme, where receivers preannounce interest in receiving data to prevent resource-scarcity deadlocks.
• Alignment preserving—Data alignment is preserved in the multiplexed stream so that binary data can be sent and processed efficiently.
• Rich functionality—The interface is rich enough to support a sockets API.

Binary Wire Protocol
The HTTP-NG team proposed the Binary Wire Protocol to enhance how the nextgeneration HTTP protocol supports remote operations.
