Struct PacketSizeStatistics

A structure to hold statistics and counters about packet sizes. Usually this will be returned through GetStatistics().

Inherited Members
Namespace: Unity.Networking.Transport.Analytics
Assembly: Unity.Networking.Transport.dll
Syntax
public struct PacketSizeStatistics
Remarks

Sizes tracked in this structure include headers for IP and UDP/TCP but do not include any link-layer headers (Ethernet, Wi-Fi, etc.) as those are too dependent on the deployment environment. Similarly, the sizes do not account for any padding that could be added to meet minimum frame size requirements (e.g. 64 bytes for Ethernet).

For WebSocket connections, the TCP header is assumed to be 32 bytes long. Furthermore even though Nagle's algorithm is disabled in Unity Transport (for non-web platforms), the nature of TCP means that the packet sizes reported here may not correspond one-to-one with sizes observed on the wire since the OS may opt to segment the traffic differently. Nevertheless, they should represent a good approximation of the shape of the traffic.

Note that if using a custom INetworkInterface, no assumptions are made about the size of headers that could be added by the OS and the sizes reported here will be exactly what is being passed to/from the network interface.
