Abstract

   This memo describes a generic application protocol kernel for
   connection-oriented, asynchronous interactions called the BEEP
   (Blocks Extensible Exchange Protocol) core.  BEEP permits
   simultaneous and independent exchanges within the context of a single
   application user-identity, supporting both textual and binary
   messages.
