---|---|
AUTH | The AUTH protocol adds a layer of authentication to JGroups |

Digest | Message digest, collecting the highest sequence number seen so far for each member, plus the messages that have higher seqnos than the ones given. |
DISCARD | Discards up or down messages based on a percentage; e.g., setting property 'up' to 0.1 causes 10% of all up messages to be discarded. |
Discovery | The Discovery protocol layer retrieves the initial membership (used by the GMS when started by sending event FIND_INITIAL_MBRS down the stack). |

FLOW_CONTROL | FLOW_CONTROL provides end-end congestion control and flow control. |
FLOWCONTROL | Title: Flow control layer 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 Copyright: Copyright (c) 2000 Company: Computer Network Laboratory |
FLUSH | The task of the FLUSH protocol is to flush all pending messages out of the system. |

HTOTAL.HTotalHeader | |
JMS | Implementation of the transport protocol using the Java Message Service (JMS). |
JMS.JMSAddress | Simple Address representing the JMS node ID or JMS topic group. |
LOOPBACK | Makes copies of outgoing messages, swaps sender and receiver and sends the message back up the stack. |
LOSS | Example of a protocol layer. |
MERGE | Simple and stupid MERGE protocol (does not take into account state transfer). |
MERGE.MergeHeader | |
MERGE2 | Protocol to discover subgroups; e.g., existing due to a network partition (that healed). |
MERGE3 | Protocol to discover subgroups; e.g., existing due to a network partition (that healed). |
MERGE3.CoordAnnouncement | |
MERGEFAST | The coordinator attaches a small header to each (or every nth) message. |
MERGEFAST.MergefastHeader | |
MessageProtocolEXAMPLE | |
MPING | Uses its own IP multicast socket to send and receive discovery requests/responses. |
NAKACK | Negative AcKnowledgement layer (NAKs), paired with positive ACKs. |
NakAckHeader | |
ParticipantGmsImpl | |
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. |
PERF | Measures time taken by each protocol to process a message. |
PERF_TP | Measures the time for a message to travel from the channel to the transport |
PerfHeader | Inserted by PERF into each message. |
PIGGYBACK | Combines multiple messages into a single large one. |
PIGGYBACK.PiggybackHeader | |
PING | The PING protocol layer retrieves the initial membership (used by the GMS when started by sending event FIND_INITIAL_MBRS down the stack). |
PingHeader | |
PingRsp | |
PingSender | Sends num_ping_request GET_MBRS_REQ messages, distributed over timeout ms |
PingWaiter | Class that waits for n PingRsp'es, or m milliseconds to return the initial membership |

PRINTOBJS | |
QUEUE | Queuing layer. |
RpcProtocolEXAMPLE | |
SEQUENCER | Implementation of total order protocol using a sequencer. |
SEQUENCER.SequencerHeader | |
SHUFFLE | This layer shuffles upcoming messages, put it just above your bottom layer. |
SIZE | Protocol which prints out the real size of a message. |
SMACK | Simple Multicast ACK protocol. |
SMACK.SmackHeader | |
STABLE | Computes the broadcast messages that are stable; i.e., that have been received by all members. |

TOTAL_OLD | ************************************************************************** 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, ... |
TOTAL_OLD.TotalHeader | class TotalHeader 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 |
