Inheritance diagram

The following diagram shows inheritance relationships for this type. Unresolved types are missing from the diagram.

Known subclasses

Name	Type	Description
EthernetLink	channel	Base for Ethernet link types. Propagation delay can be specified with the length of the cable, i.e. in meters instead of nanoseconds or microseconds.
ThruputMeteringChannel	channel	This channels adds support for thruput metering to the datarate channel. A cDatarateChannel extended with throughput calculation. Values are displayed on the link, using the connection's "t=" or "tt=" display string tag.

Parameters

Name	Type	Default value	Description
disabled	bool	false
delay	double	0s	propagation delay
datarate	double	0bps	bits per second; 0=infinite
ber	double	0	bit error rate (BER)
per	double	0	packet error rate (PER)

Properties

Name	Value	Description
