本文档提供了错误和流量控制协议（EFCP）规范。EFCP向应用进程提供进程间通信(IPC)服务，该应用进程可以是(N+1)-IPC进程(IPCP)，具有所请求的服务质量(QoS)。一个或多个服务数据单元(SDU)在(N)端口id上传递到(N)DIF(分布式IPC设施)以发送到目的地应用进程。由(N)-DIF传送的协议数据单元(PDU)被传送到(N)-port-id以用于使用应用程序处理。本文档描述了EFCP在RINA中的位置、EFCP包含的组件、EFCP工作中涉及的机制和策略，以及管理连接所需的计时器和控制机制。EFCP包括两个逻辑组件，即提供紧绑定机制的数据传输过程(DTP)和提供松绑定机制的数据传输控制过程(DTCP)。本文件规定:-服务定义；-EFCP概述；-对递归互联网络架构(RINA)内EFCP的放置的描述；-数据传输协议(DTP)和数据传输控制协议(DTCP)的共同要素；-DTP结构和功能；-DTCP结构和功能；-EFCP中所有策略的信息列表。

This document provides the Error and Flow Control Protocol (EFCP) specification. EFCP provides an inter-process communication (IPC) service to an application process, which can be a (N+1)-IPC process (IPCP), with the requested Quality of Service (QoS). One or more service data units (SDUs) are passed on the (N)-port-id to the (N)-DIF (distributed IPC facility) to be sent to the destination application process. Protocol data units (PDUs) transferred by the (N)-DIF are delivered to the (N)-port-id for the using Application Process. This document describes 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 procedures (DTP), providing tightly bound mechanisms and the data transfer control procedures (DTCP), which provides loosely bound mechanisms.
This document provides:
- the service definition;
- an overview of EFCP;
- a description of the placement of EFCP within recursive internetwork architecture (RINA);
- the common elements of data transfer protocol (DTP) and data transfer control protocol (DTCP);
- DTP structure and functions;
- DTCP structure and functions;
- an informative list of all policies in EFCP.
