Sideband

Appearance

Sideband Protocol (SBP) ​

Authority: Navigation (Non-normative)
Purpose: Overview and navigation for SBP application framing layer.

SBP defines application-level framing for Sideband. It is topology-agnostic and can be carried over relay (SBRP) or direct (SBDP) session layers.

Scope ​

  • Frame types and wire encoding
  • Handshake, message, ack, error semantics
  • Ordering and delivery guarantees

Not Included ​

  • Transport (see @sideband/transport)
  • Encryption (see SBRP or SBDP)
  • Authentication
