CAUSAL |
Implements casual ordering layer using vector clocks
Causal protocol layer guarantees that if message m0 multicasted
by a process group member p0 causes process group member
p1 to multicast message p1 then all other remaining process group
members in a current view will receive messages in order m0
followed by m1. |

Description: This layer limits the number of sent messages without a receive of an own message to MAXSENTMSGS,
just put this layer above GMS and you will get a more

MERGEFAST.MergefastHeader | |
NAKACK | Negative AcKnowledgement layer (NAKs), paired with positive ACKs. |
NakAckHeader | |
PARTITIONER | This layer can be put on top of the bottommost layer and is useful to simulate partitions. |
PARTITIONER.PartitionerHeader | The Partitioner header normally (type = NORMAL) contains just the partition number that is checked to discard messages
received from other partitions. |

by sending event FIND_INITIAL_MBRS down the stack). |

class TOTAL_OLD extends Protocol
TODO: (more comments)
Sequencer based total ordering protocol layer
- requires the following layers "below" it in the stack
(or layers with equivalent functionality):
GMS, FD, PING, UDP, ... |

The header that is prepended to every message passed down through the TOTAL_OLD layer
and removed (and processed) from every message passed up through the TOTAL_OLD layer
|

Total order implementation based on
The Totem Single-Ring Ordering and Membership Protocol
However, this is an adaption of algorithm mentioned in the research paper above since we reuse
our own membership protocol and failure detectors. |
