ISO 21323:2016旨在适用于任何类型的空间任务或基础设施，这些任务或基础设施缺乏通信资源，并且无论其复杂性如何，都会受到长延迟和/或临时网络分区的影响。本推荐标准旨在成为所有CCSDS机构的统一标准。此外，本规范的存在是为了利用地面和天基资产之间机载和传输中的各种互联协议的基础服务。 ISO 21323:2016适用于声称符合CCSDS捆绑协议的所有系统。 对于底层传输协议的选择是不可知的，因为BP可以在AOS、空间数据包、邻近1空间链路协议以及各种互联网和地面协议上运行。 CCSDS认为，重要的是记录所选建议的基本原理，以便未来对拟议变更或改进的评估不会忽略之前的决定。在空间链路中使用捆绑协议的概念和原理见参考文献[H1]。

ISO 21323:2016 is designed to be applicable to any kind of space mission or infrastructure that is communication-resource poor and is subject to long latencies and/or temporary network partitions, regardless of complexity. It is intended that this Recommended Standard become a uniform standard among all CCSDS Agencies. In addition, this specification exists to utilize the underlying service of various internetworking protocols both onboard and in transit between ground and space-based assets. ISO 21323:2016 is intended to be applied to all systems that claim conformance to the CCSDS Bundle Protocol. It is agnostic to the choice of underlying transmission protocol in that BP can function over AOS, Space Packet, Proximity-1 Space Link Protocol, and various Internet and ground based protocols. The CCSDS believes it is important to document the rationale underlying the recommendations chosen, so that future evaluations of proposed changes or improvements will not lose sight of previous decisions. The concept and rationale for the use of a bundle protocol in space links may be found in reference [H1].
