Web(a)(2 points) A total ordered multicast is also causal. (b)(3 points) If the processes in a system use R-multicast, and each channel follows FIFO order, then causal ordering is satisfied. (c)(3 points) We can implement the ISIS algorithm for total ordering on top of (or using) causal-ordered multicast, to achieve a total causal multicast. Page 2 Web1. Explain the difference between FIFO order, casual order, and total order multicast with examples. 2. Show how to implement a causal order multicast using vector time stamps. 3. In Byzantine agreement protocol k+ 1 rounds of message exchanges are needed to tolerant kfaults. The number of processes nis at least 3k+ 1. Assume P 1 and P 2
