Running a Byzantine clock synchronization protocol interleaved with consensus protocol might lead to a protocol with lower latency, since the timeouts are dynamically adjusted instead of being increased for each failed iteration.
The optimal waiting time, derived within [12], depends on the target delivery latency (NT) and the timeout probability and is approximated in (3).
Ping with a longer timeout to identify latency problems.
This is because the probability of packet loss because of a timeout of target delay latency becomes more decreased with higher delay latency in scheduler.
However, in the current test-bed implementation, the simple HTTP request/response latency measurement approach is used with a timeout threshold (i.e. in a corresponding way to the previous tHigh threshold).
where P n, i (T) is the estimated probability of successfully completing delivery of the media data unit n in discrete time interval T on channel i, NT is the target chunk delivery latency and t n, i * is the optimal waiting threshold (timeout in terms of intervals T) for receipt of the media chunk before triggering a switch to channel i.
Of course, there are certain cases where serverless just doesn't make sense, but those are disappearing at a rapid rate (for example, Lambda's 5-minute timeout was recently tripled to 15 minutes)—and reasons such as lock-in or latency are generally nonsense or a thing of the past.
The timeout detection threshold is set to 500 ms. The mean of the link latency is 50 ms. As shown in Figure 9, the changes of group size are in the range of +/-10+/-10%25%, +/-50+/-50%he original group size.
Resolutions of larger chains, e.g., 200, can often result in timeouts and unnecessary retransmissions, overloading the network and the name server, and increasing the latency for clients' queries.
