Constructor Detail

RoutingConfiguration

                    int maxFailures,
                    int parallel)

RoutingConfiguration

public RoutingConfiguration(int maxNoNewInfoDiff,
                    int maxFailures,
                    int maxSuccess,

RoutingConfiguration

public RoutingConfiguration(int directHits,
                    int maxNoNewInfoDiff,
                    int maxFailures,

RoutingConfiguration

public RoutingConfiguration(int maxDirectHits,
                    int maxNoNewInfoDiff,
                    int maxFailures,
                    int maxSuccess,
                    int parallel,
                    boolean forceTCP)

Sets the routing configuration and its stop conditions.

Parameters:

maxDirectHits - Number of direct hits (d): This is used for fetching data. If d peers have been contacted that have the data stored, routing stops.

maxNoNewInfoDiff - Number of no new information (n): This is mainly used for storing data. It searches the closest peers and if n peers do not report any closer nodes, the routing stops.

maxFailures - Number of failures (f): The routing stops if f peers fail to respond.

maxSuccess - Number of success (s): The routing stops if s peers respond.

parallel - Number of parallel requests (p): This tells the routing how many peers to contact in parallel.

forceTCP - Flag to indicate that routing should be done with TCP instead of UDP

Method Detail

maxDirectHits

public int maxDirectHits()

maxNoNewInfoDiff

public int maxNoNewInfoDiff()

This returns the difference to the min value of P2P configuration. We need to have a difference, because we need to search at least for min peers in the routing, as otherwise if we find the closest node by chance, then we don't reach min.

Returns:

maxNoNewInfo

public int maxNoNewInfo(int minimumResults)

maxFailures

public int maxFailures()

maxSuccess

public int maxSuccess()

parallel

public int parallel()

isForceTCP

public boolean isForceTCP()

Returns:

True if the routing should use TCP instead of the default UDP
