Interface Summary
QUEUE.Observer  
 

Class Summary
AUTOCONF Senses the network configuration when it is initialized (in init()) and sends a CONFIG event up and down the stack.
BSH Beanshell ("www.beanshell.org") interpreter class.
BSH.BshHeader  
CAUSAL Implements casual ordering layer using vector clocks
CAUSAL.CausalHeader  
ClientGmsImpl Client part of GMS.
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  
ENCRYPT1_4 ENCRYPT1_4 layer.
ENCRYPT1_4.EncryptHeader  
EXAMPLE Example of a protocol layer.
FC Simple flow control protocol based on a credit system.
FC.FcHeader  
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 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.
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.
MERGEFAST The coordinator attaches a small header to each (or every nth) message.
MERGEFAST.MergefastHeader  
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
TRACE  
TUNNEL Replacement for UDP.
TunnelHeader  
UDP IP multicast transport based on UDP.
UdpHeader  
UNICAST Reliable unicast layer.
UNICAST.UnicastHeader  
VectorTime Vector timestamp used in CAUSAL order protocol stack
VERIFY_SUSPECT Catches SUSPECT events traveling up the stack.
VERIFY_SUSPECT.VerifyHeader  
VIEW_ENFORCER Used by a client until it becomes a member: all up messages are discarded until a VIEW_CHANGE is encountered.
WANPING Similar to TCPPING, except that the initial host list is specified as a list of logical pipe names.
WANPIPE Logical point-to-point link.
WanPipeAddress Logical address for a WAN pipe (logical link)
