基于星球机器人分布计算系统的原子组播协议

Atomic multicast protocol for distributed computing systems of planetary rover

针对星球机器人分布计算系统容错的可靠组播通信,提出了一种基于向量时间的原子组组播协议。协议从星球机器人分布计算系统及通信模型的特点出发,使用向量时间和令牌进程来标识和保证全局投递顺序,通过令牌进程对不稳定消息的转发和两阶段提交来保证投递原子性和虚同步。模拟实验表明,协议提供了一个代价较小的可靠组播方法,具有快速和轻量的优点。

An atomic multicast protocol based on vector time is proposed for reliable group communication ot alsmoutea computling system of planetary rover. According to the features of distributed computing system of planetary rover uses vector time and token process to achieve total ordering of message. Atomicity and virtual synchrony are assured through two phases commit and the retransmission of unstable messages. The experiment shows that it provides an inexpensive way to achieve reliable group multicast and has the advantages of lightweight and fastness.
