标准摘要
[中文适用范围]: 本文档提供了错误和流量控制协议 (EFCP) 规范。EFCP 为应用程序进程提供进程间通信 (IPC) 服务,该进程可以是 (N+1)-IPC 进程 (IPCP),并具有请求的服务质量 (QoS)。一个或多个服务数据单元 (SDU) 在 (N)-port-id 上传递到 (N)-DIF(分布式 IPC 设施),以发送到目标应用程序进程。由 (N)-DIF 传输的协议数据单元 (PDU) 被传送到 (N)-port-id 以供使用应用程序进程使用。本文档描述了 EFCP 在 RINA 中的位置、EFCP 所包含的组件、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 包含两个逻辑组件,即提供紧密绑定机制的数据传输程序 (DTP) 和提供松散绑定机制的数据传输控制程序 (DTCP)。本文档提供: — 服务定义; — EFCP 概述; — EFCP 在递归网络间体系结构 (RINA) 中的位置描述; — 数据传输协议 (DTP) 和数据传输控制协议 (DTCP) 的共同元素; — DTP 结构和功能; — DTCP 结构和功能; — EFCP.en 中所有策略的信息列表 [外文原描述]: 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.en
