| ChecksumConfigurationElement | Provides configuration for the file checksums used by both the data server and client. |
| DataServerClientProtocolGetLogFileContentsHeader | Header sent to the data server for the GetLogFileContents command. |
| DataServerClientProtocolHeader | Abstract base class for the header sent by a client when communicating with a data server. |
| DataServerClientProtocolReadHeader | Represents the header sent by a client to the data server when reading a block. |
| DataServerClientProtocolWriteHeader | Represents the header a client sends to a data server when writing a block. |
| DataServerConfigurationElement | Provides configuration settings for the data servers. |
| DataServerMetrics | Provides metrics about a data server. |

| HeartbeatData | Abstract base class for the data sent by a DataServer to a NameServer during a heartbeat |
| HeartbeatResponse | Represents the response sent by the NameServer to a Heartbeat message from the DataServer. |
| InitialHeartbeatData | Heartbeat data sent by the name server the first time it sends a heartbeat to the server. |
| InvalidPacketException | Exception that is thrown when a Packet's data does not match its checksum. |
| NameServerConfigurationElement | Provides configuration information about the name server. |
| NewBlockHeartbeatData | Represents the data sent by a data server during a heartbeat when it informs the name server it has received a new block. |
| Packet | Represents a part of a block. |
| ReplicateBlockHeartbeatResponse | Provides data for a ReplicateBlock command. |
| SafeModeException | Exception that is thrown if the name server is accessed while still in safe mode. |
| StatusHeartbeatData | Provides some general status data about the data server. |
Interfaces| Interface | Description | |
