Introduction

The Bundle Protocol (BP) standard proposal was originally formulated by the Internet Engineering Task Force (IETF), and the standard proposal released is RFC5050 The Advisory Committee on Space Data Systems (CCSDS) evaluates that for the harsh space communication environment, the use of RFC5050 The BP protocol stipulated in the standard proposal can improve the communication capability: Based on the RFC5050 standard proposal, the CCSDS organization aims at Supplementary provisions have been made for inter-communication application requirements, and the CCSDSBP protocol standard proposal has been released, namely CCSDS734:2-B-1 "BundlePro- Standard, namely ISO 21323:2016: In order to ensure the integrity of the technical content, this document adopts non-equivalent adoption of ISO 21323:2016, refers to and joins the IETF Space Data and Information Transmission System bundle agreement

1 Scope

This document specifies the data unit format, protocol flow, business requirements of the aggregation layer, and security considerations of the bundle protocol (hereinafter referred to as BP protocol) and other content, supplementary provisions are made on the application of BP protocol in spatial data and transmission system, mainly including convergence layer adapter, service type extension, etc: extension, aggregate custody signaling, delay-tolerant load adjustment, and protocol management information content: This document is applicable to data transmission of space mission systems where communication resources are tight and communication time is extended, and the network may be temporarily interrupted:
