This document provides the specification of the Error and Flow Control Protocol (EFCP). EFCP provides an inter-process communication service to the Application Process, which may be a (N+1)-IPC Process, with the requested Quality of Service. One or more SDUs are passed on the (N)-port-id to the (N)-DIF to be sent to the destination application process. PDUs transferred by the (N)-DIF are delivered to the (N)-Port-id for the using Application Process. In the following pages it will be described the placement of EFCP within RINA, the components EFCP consists of, and the mechanisms and policies that are involved in EFCP’s work, and the timers and control mechanisms required to manage the connection.

EFCP comprises two logical components, the Data Transfer Protocol (DTP), providing tightly bound mechanisms, as defined below, and the Data Transfer Control (DTCP) protocol, which provides loosely bound mechanisms.

This document provides the following: the service definition, an overview of EFCP, a description of the placement of EFCP within RINA, the common elements of DTP and DTCP, DTP structure and functions, and DTCP structure and functions. An informative list of all policies in EFCP is provided as well.
