Class Summary |
AUTOCONF |
Senses the network configuration when it is initialized (in init()) and sends a CONFIG event up
and down the stack. |
CAUSAL |
Implements casual ordering layer using vector clocks
|

CoordGmsImpl |
|
DEADLOCK |
Tests the deadlock detection mechanism of RequestCorrelator. |
DELAY |
Delays incoming/outgoing messages by a random number of milliseconds (range between 0 and n
where n is determined by the user). |
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. |
DUMMY |
|
EXAMPLE |
Example of a protocol layer. |
FD |
Failure detection based on simple heartbeat protocol. |
FD_PID |
Process-ID based FD protocol. |
FD_PID.FdHeader |
|
FD_PROB |
Probabilistic failure detection protocol based on "A Gossip-Style Failure Detection Service"
by Renesse, Minsky and Hayden. |
FD_PROB.FdHeader |
|
FD_SIMPLE |
Simple failure detection protocol. |
FD_SIMPLE.FdHeader |
|
FD_SOCK |
Failure detection protocol based on sockets. |
FD_SOCK.FdHeader |
|
FD.FdHeader |
|
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

Company: Computer Network Laboratory |
FLUSH |
The task of the FLUSH protocol is to flush all pending messages out of the system. |
FlushRsp |
|
FRAG |
Fragmentation layer. |
FRAG.FragHeader |
|
GMS |
Group membership protocol. |
GmsImpl |
|
HDRS |
Example of a protocol layer. |
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. |
MessageProtocolEXAMPLE |
|
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. |
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 |
|
PRINTMETHODS |
|
PRINTOBJS |
|
QUEUE |
Queuing layer. |
RpcProtocolEXAMPLE |
|
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. |
STATE_TRANSFER |
State transfer layer. |
TCP |
TCP based protocol. |
TCPGOSSIP |
The TCPGOSSIP protocol layer retrieves the initial membership (used by the GMS when started
by sending event FIND_INITIAL_MBRS down the stack). |
TcpHeader |
|
TCPPING |
The TCPPING protocol layer retrieves the initial membership (used by the GMS when started
by sending event FIND_INITIAL_MBRS down the stack). |
TOTAL |
Implements the total ordering layer using a message sequencer
|
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 |
TOTAL_TOKEN |
Total order implementation based on
The Totem Single-Ring Ordering and Membership Protocol
|
TOTAL_TOKEN.RingTokenHeader |
|
TOTAL_TOKEN.TotalTokenHeader |
|
TOTAL.Header |
The header processed by the TOTAL layer and intended for TOTAL
inter-stack communication |
