RoundTripTimeStatistics structure

Represents round trip time information for a StreamSocket object.

Syntax


public value struct RoundTripTimeStatistics

Members

The RoundTripTimeStatistics structure has these fields.

FieldData typeDescription
Max | max

Number [JavaScript] | System.UInt32 [.NET] | uint32 [C++]

The maximum sampled round trip time, in microseconds, for a StreamSocket object.

This value is always 0 on systems that do not have extended TCP statistics enabled by default.

Min | min

Number [JavaScript] | System.UInt32 [.NET] | uint32 [C++]

The minimum sampled round trip time, in microseconds, for a StreamSocket object.

This value is always 0 on systems that do not have extended TCP statistics enabled by default.

Sum | sum

Number [JavaScript] | System.UInt32 [.NET] | uint32 [C++]

A smoothed value round trip time, in microseconds, computed from all sampled round trip times for a StreamSocket object. The smoothing is a weighted additive function that uses the Variance member.

This value is always 0 on systems that do not have extended TCP statistics enabled by default.

Variance | variance

Number [JavaScript] | System.UInt32 [.NET] | uint32 [C++]

The round trip time variation, in microseconds, for a StreamSocket object. This value is used for receive window auto-tuning.

This value is always 0 on systems that do not have extended TCP statistics enabled by default.
