udpOut output

gate to the UDP layer

tcpIn input

gate from the TCP layer

tcpOut output

gate to the TCP layer

Unassigned submodule parameters:

Name Type Default value Description
nTree.rpcUdpTimeout double

default timeout value for direct RPCs

nTree.rpcKeyTimeout double

default timeout value for routed RPCs

nTree.optimizeTimeouts bool

calculate timeouts from measured RTTs and network coordinates

nTree.rpcExponentialBackoff bool

if true, doubles the timeout for every retransmission

nTree.localPort int

UDP port for overlay messages

nTree.overlayId int

identifies the overlay this node belongs to (used for multiple overlays)

nTree.debugOutput bool

enable debug output

nTree.keyLength int

overlay key length in bits

nTree.nodeId string

optional nodeId as string in hexadecimal notation

draw arrow to successor node?

nTree.hopCountMax int

maximum number of overlay hops

nTree.recNumRedundantNodes int

numRedundantNodes for recursive routing

nTree.joinOnApplicationRequest bool

only join the overlay on application request

nTree.collectPerHopDelay bool

delay statistics for single hops

nTree.routeMsgAcks bool

use RPCs for route messages

nTree.lookupRedundantNodes int

number of next hops in each step

nTree.lookupParallelPaths int

number of parallel paths

nTree.lookupParallelRpcs int

number of nodes to ask in parallel

nTree.lookupVerifySiblings bool

true, if siblings need to be authenticated with a ping

nTree.lookupMajoritySiblings bool

true, if sibling candidates are selected by a majority decision if using parallel paths

send a new RPC immediately after an RPC timeouts

nTree.lookupNewRpcOnEveryResponse bool

send a new RPC after every response, even if there was no progress

nTree.lookupFinishOnFirstUnchanged bool

finish lookup, if the last pending RPC returned without progress

nTree.lookupVisitOnlyOnce bool

if true, the same node is never asked twice during a single lookup

nTree.lookupAcceptLateSiblings bool

if true, a FindNodeResponse with sibling flag set is always accepted, even if it is from a previous lookup step

nTree.routingType string

default routing mode (iterative, semi-recursive,...)

nTree.rejoinOnFailure bool

rejoin after loosing connection to the overlay?

nTree.sendRpcResponseToLastHop bool

needed by KBR protocols for NAT support

nTree.recordRoute bool

nTree.maxChildren int

the maximum number of childs in the laodbalancing tree

nTree.AOIWidth double

the size of the area of interest (i.e. subscriptionSize)
