Public struct FNetConnectionSaturationAnalytics Struct wrapping Per Net Connection saturation analytics.  
Public class FNetControlMessage Forward declarations.  
Public class FNetControlMessageInfo Contains info about a message type retrievable without static binding (e.g. whether it's a valid type, friendly name string, etc)  
Public class FNetPacketNotify FNetPacketNotify - Drives delivery of sequence numbers, acknowledgments and notifications of delivery sequence numbers  
Public class FNetPing Central class for handling all Player/NetConnection ping collection and calculation.  
Public struct FNetQueuedActorDelinquencyAnalytics Tracks data related specific to a NetConnection that can can result in prolonged periods of apparent network inactivity, despite actually receiving traffic.  
Public class FNetworkCongestionControl One implementation of network traffic control based on the unacked bytes in flight and the estimated uplink bandwidth and propagation round-trip time.  
Public class FNetworkProfiler Network profiler, using serialized token emission like e.g. script and malloc profiler.  
Public class FNetworkProfilerHeader    
Public struct FNetworkProfilerScopedIgnoreReplicateProperties Can be used to enforce a scope where we don't want to track properties.  
Public struct FNetworkReplayDelegates    
Public class FNetworkTrafficAnalyzer A Network traffic analyzer that keeps track of useful information including the RTT and uplink bandwidth of the latest received packet to help the congestion control module work.  
Public class FObjectReplicator Represents an object that is currently being replicated or handling RPCs.  
Public class FOutBunch A bunch of data to send.  
Public struct FPingValues Struct for returning ping values, in seconds.  
Public class FReceivingRepState Replication State needed to track received properties.  
Public class FRepChangedHistory Represents a single changelist, tracking changed properties.  
Public class FRepChangelistState Stores changelist history (that are used to know what properties have changed) for objects.  
Public struct FRepClassDescriptor    
Public class FRepHandleIterator Iterates over a changelist, taking each handle, and mapping to rep layout index, array index, etc.  
Public class FRepLayout This class holds all replicated properties for a given type (either a UClass, UStruct, or UFunction).  
Public class FRepLayoutCmd Represents a single property, which could be either a Top Level Property, a Nested Struct Property, or an element in a Dynamic Array.  
Public struct FReplayPlaylistParams Set of parameters used with UGameInstance::PlayReplayPlatlist to control how the playlist is started.  
Public struct FReplayPlaylistTracker Used with UGameInstance::PlayReplayPlaylist to manage playing a set of Replays in succession.  
Public struct FReplayPlaylistUpdatedOptions Set of options that can be updated before starting each replay in a playlist.  
Public struct FReplicatedActorProperty Struct containing property and offset for replicated actor properties  
Public class FReplicationChangelistMgr FReplicationChangelistMgr manages a list of change lists for a particular replicated object that have occurred since the object started replicating Once the history is completely full, the very first changelist will then be merged with the next one (freeing a slot) This way we always have the entire history for join in progress players This information is then used by all connections, to share the compare work needed to determine what to send each connection Connections will send any changelist that is new since the last time the connection checked  
Public class FRepParentCmd A Top Level Property of a UClass, UStruct, or UFunction (arguments to a UFunction).  
Public struct FRepPropertyDescriptor    
Public struct FRepSerializationSharedInfo Holds a set of shared net serialized properties  
Public struct FRepSerializedPropertyInfo Holds the unique identifier and offsets/lengths of a net serialized property used for Shared Serialization  
Public struct FRepSharedPropertyKey    
Public class FRepState Replication State that is unique Per Object Per Net Connection.  
Public struct FRepStateStaticBuffer Holds deep copies of replicated property data for objects.  
Public struct FRPCDoSCounters Struct containing RPC counters covering any time period (e.g. frame/second/arbitrary-period)  
Public class FRPCDoSDetection RPC DoS detection  
Public struct FRPCDoSState Stores the RPC DoS detection state (either settings from the config file, or the active DDoS detection state)  
Public struct FRPCDoSStateConfig Configuration for RPC DoS Detection states
