  drcl.inet.protocol.cbt.CBTTimingPack

public class CBTTimingPack

extends java.lang.Object

Defines all the timing parameters used by CBT. Refer to draft-ietf-idmr-cbt-spec-v3-01.txt for the default values and formula. The values that are defined in the draft but not defined here are [HelloInterval], [HelloPreference] and [DrTransTimer].

Constructor Summary

CBTTimingPack()
See all the getter methods for the default values.

CBTTimingPack(double holdTime_, int maxRtx_, double rtxInterval_, double echoIntervalBase_)
Default formula for other values: [JoinTimeout] = 3.5 * [RtxInterval] [TransientTimeout] = [JoinTimeout] [ChildDelTimer] = 1.5 * [HoldTime] [UpstreamExpireTime] = [MaxRtx] * [RtxInterval] + [HoldTime] [DownStreamExpireTimeBase] = [UpstreamExpireTime] +[EchoIntervalBase]
