Filename of the routing table [RoutingTable]

The P-Grid routing table file includes information about the P-Grid network. The file can be set at RoutingTable. If the given file does not exist a new file will be created at startup.
Default: RoutingTable.xml

Filename of the data table [DataTable]

The managed data items are stored in the DataTable file. If this file does not exists, a new one is created at startup.
Default: DataTable.xml

Initialization file of the P-Grid mapping tree [TreeIniFile]

The initialization file is used to construct the P-Grid mapping tree to map ASCII string to binary strings. If the initialization file does not exist the tree is constructed by the database file. The tree is stored in the initialization file after construction to speed up consecutive startups.
Default: PGridTree.ini

Database file of the P-Grid mapping tree [TreeDbFile]

The database file is used to construct the P-Grid mapping tree if the initialization file does not exist.
Default: PGridTree.dat

Amount of stored fidget hosts [MaxFidgets]

MaxFidgets references are stored in the local routing table used to initiate exchanges.
Default: 10

Maximum amount of recursive exchanges [MaxRecursions]

The maximum amount of recusive initiated exchanges during an exchange.
Default: 3

Amount of stored references per routing level [MaxReferences]

MaxReferences references are stored for every level of the local routing table to route queries.
Default: 10

Amount of random searches [RandomSearches]

RandomSearches random searches are initiated for every search created by the local user to improve search results. Less random searches lead to lower network bandwidth consumption and possible smaller result sets, whereas a greater amount of random searches lead to a higher bandwidth consumption and possible greater result sets.
Default: 2

Exchange rate [ExchangeRate]

The minimum period before initiating an exchange with a peer. The ExchangeRate can vary depending on the current amount of managed data items, the length of the local path, and when the local peer is bootstrapping. The period should be given in milliseconds.
Default: 60000

Balancing replication load [ReplicationBalance]

Load-balancing is guaranteed by P-Grid during network construction for static content. If the amount of peers and data is changing during P-Grid's operation time, balancing replication load is necessary to analyze the current load distribution. If not it can be disabled to reduce bandwidth consumption of P-Grid.
Default: true

Protocol compression level (ZLIB compression) [CompressionLevel]

CompressionLevel indicates the used compression level before sending messages over the P-Grid network. The compression level can be between 0 (no compression) and 9 (best compression).
For further details see the Java java.util.zip package description.
Default: 9

Addresses of bootstrap hosts [BootstrapHosts]

P-Grid bootstrap hosts are required for new hosts to join the P-Grid network the first time. A list of bootstrap hosts can be given at BootstrapHosts represented by their IP-address or their name and the listening port (<ip:port> or <name:port>). The hosts should be separated by white space.
Default: www.p-grid.org:1805

Connection speed of local host [ConnectionSpeed]

The maximum speed Gridella can communicate with other host over the network. ConnectionSpeed should be a valid integer representing the speed in kb/second.
Default: 56

Is the local host behind a firewall [BehindFirewall]

If Gridella is running at a host behind a firewall, the BehindFirewall property must be set to true, false otherwise.
Default: false

Resolve IP addresses to host addresses [ResolveIPs]

If IP addresses should be resolved to host names, the ResolveIPs property must be set to true, false otherwise.
Default: true

Initiate exchanges automatically [InitiateExchanges]

If exchanges should be initiated by the local host, InitiateExchanges must be set to true, false otherwise. If a new host wants to join the P-Grid network the first the property must be set to true.
Default: true
