public class sIGMP

extends Protocol

A very preliminary IGMP protocol. This component only implements REPORT and LEAVE. REPORT retransmission and QUERY are not implemented. And this component can be used in both a host and a router.

Contracts:

• .service_id@: IDLookup and IDConfig as client.
• .mcast_service@ (for host): IDConfig as reactor.
• .mcastHost@ (for router): McastHostEvent as initiator.
• down@: PktSending and PktDelivery as client.

Reference:

• RFC2236.

Method Detail

getName

public java.lang.String getName()

Description copied from class: Component

Returns the (informational) name of the component.

Overrides:

getName in class Component

duplicate

public void duplicate(java.lang.Object source_)

Description copied from class: Component

Duplicates the content of source_, including ID, name, child components and connections among them, to this component. Subclasses need to override this method to copy its own variables.

info

public java.lang.String info()

Provide multicast group membership information on each interface.

Overrides:

info in class Component

reset

public void reset()

Description copied from class: Component

Resets the component for being used anew. All the internal variables must be set to the initial state. All the ports and child components are reset as well.

Overrides:

reset in class Component

join

public void join(long group_)

Makes this host joins the multicast group.

leave

public void leave(long group_)

Makes this host leaves the multicast group.
