Add()

void node::TxOrphanageImpl::PeerDoSInfo::Add ( const Announcement & ann )

Here is the call graph for this function:

GetDosScore()

FeeFrac node::TxOrphanageImpl::PeerDoSInfo::GetDosScore ( TxOrphanage::Count max_peer_latency_score, TxOrphanage::Usage max_peer_memory ) const

inline

There are 2 DoS scores:

• Latency score (ratio of total latency score / max allowed latency score)
• Memory score (ratio of total memory usage / max allowed memory usage).

If the peer is using more than the allowed for either resource, its DoS score is > 1. A peer having a DoS score > 1 does not necessarily mean that something is wrong, since we do not trim unless the orphanage exceeds global limits, but it means that this peer will be selected for trimming sooner. If the global latency score or global memory usage limits are exceeded, it must be that there is a peer whose DoS score > 1.
