Constructor Details

TraversingInternetDiscoveryChildrenHandler

public TraversingInternetDiscoveryChildrenHandler(int myNetworkId,
 IdentityPublicKey myPublicKey,
 IdentitySecretKey mySecretKey,
 ProofOfWork myProofOfWork,
 long initialPingDelayMillis,
 long pingIntervalMillis,
 long pingTimeoutMillis,
 long maxTimeOffsetMillis,
 Map<IdentityPublicKey,InetSocketAddress> superPeerAddresses,
 long pingCommunicationTimeoutMillis,
 long maxPeers)

Parameters:

myNetworkId - the network we belong to

myPublicKey - own public key

mySecretKey - own secret key

myProofOfWork - own proof of work

initialPingDelayMillis - time in millis after InternetDiscoveryChildrenHandler.channelActive(ChannelHandlerContext) has been fired, we start to ping super peers

pingIntervalMillis - interval in millis between a ping

pingTimeoutMillis - time in millis without ping response before a peer is assumed as unreachable

maxTimeOffsetMillis - time millis offset of received messages' timestamp before discarding them

superPeerAddresses - inet addresses and public keys of super peers

pingCommunicationTimeoutMillis - time in millis a traversed connection to a peer will be discarded without application traffic

maxPeers - maximum number of peers to which a traversed connection should be maintained at the same time
