| AckMcastReceiverWindow | Keeps track of messages received from various senders. |
| AckMcastSenderWindow | Keeps track of ACKs from receivers for each message. |
| AckReceiverWindow | Counterpart of AckSenderWindow. |
| AckSenderWindow | ACK-based sliding window for a sender. |
| Configurator | The task if this class is to setup and configure the protocol stack. |
| Configurator.ProtocolConfiguration | Parses and encapsulates the specification for 1 protocol of the protocol stack, e.g. |
| GossipClient | Local stub for clients to access one (or more) GossipServers. |
| GossipData | Encapsulates data sent between GossipServer and GossipClient
|
| GossipRouter | Router for TCP based group comunication (using layer TCP instead of UDP). |
| GossipServer | Maintains a cache of member addresses for each group. |
| Interval | Manages retransmission timeouts. |
| IpAddress | Network-dependent address (Internet). |
| LogicalAddress | Logical address that spans the lifetime of a member. |
| MessageProtocol | Based on Protocol, but incorporates RequestCorrelator and GroupRequest: the latter can
be used to mcast messages to all members and receive their reponses. |
| NakReceiverWindow | Keeps track of messages according to their sequence numbers. |
| Protocol | The Protocol class provides a set of common services for protocol layers. |
| ProtocolStack | A ProtocolStack manages a number of protocols layered above each other. |
| Retransmitter | Maintains a pool of sequence numbers of messages that need to be retransmitted. |
| Router | Router for TCP based group comunication (using layer TCP instead of UDP). |
| RouterStub | |
| RpcProtocol | Base class for group RMC peer protocols. |
| StateTransferInfo | Contains parameters for state transfer. |
