Destructable, TransportLayer<Identifier,java.nio.ByteBuffer>

All Known Implementing Classes:

IdentityTransportLayerImpl, TableTransprotLayerImpl

public interface TableTransportLayer<Identifier,Key,Value>
extends TransportLayer<Identifier,java.nio.ByteBuffer>

Keeps a store of information at each node, such that other nodes can query for the information. This is useful for example, for certificates. The information in this table must be constant, and must be able to propagate epidemically.
