public class CBT

extends Routing

implements McastRouting, CBTConstants, ActiveComponent

Implements the Core Based Tree (CBT) Multicast Routing protocol. This version does not work on virtual or tunnel interfaces. Doesn't implement - support of (*, Core) and (S, G) - unidirectional pruned state (instead, a quit simply deletes the child interface from the entry) - broadcast LAN, HELLO protocol, determining DR - Bootstrap - check on incoming interface for data forwarding - exact tunneling for a non-member source to send pkts (instead, just forward it hop-by-hop toward the core, the pkts may be picked up by an on-tree router along the way)

Returns the (informational) name of the component.

Overrides:

getName in class Component

getDebugLevelNames

public java.lang.String[] getDebugLevelNames()

Description copied from class: Component

Returns the names of defined debug levels; subclasses should override this method if debug levels are defined.

Overrides:

getDebugLevelNames in class Component

duplicate

public void duplicate(java.lang.Object source_)

Description copied from class: Component
