摘要
卫星互联网是满足未来无处不在的网络接入的重要手段,具有覆盖范围广、通信容量大、全球无缝连接等优点,在灾害预防、海洋作业等方面具有广泛的应用场景。从卫星互联网如何实现确定性传输的愿景出发,结合现有的确定性网络技术,提出卫星确定性网络架构,指出卫星确定性网络中确定性接入、多业务差异化保障、动态资源分配和路径备份方面存在的挑战以及未来的发展方向。
Satellite internet is an important means to meet the ubiquitous network access in the future.It has a wide range of application scenarios in disaster prevention,marine operation and scientific research broadband on account of its wide coverage,large communication capacity and global seamless connection.Started from the vision of the deterministic transmission of satellite internet,combined with the existing deterministic network technology,the satellite deterministic network architecture was put forward,and the existing challenges and future development in deterministic access,multi-service differentiation guarantee,dynamic resource allocation and path backup of satellite deterministic network were pointed out.
