RE: [ssm] Apple patent search

["Michael Luby" <[e-mail]>]

I don't think that is the correct patent.  More likely the one I list here:

United States Patent  5,517,494

Method and system of multicast routing for groups with a single transmitter


Abstract
A method of implementing a multicast routing protocol in routers is provided
to manage the assignment of multicast transport addresses and to forward
data from a single transmitting endpoint to multiple receiving endpoints.
This method in conjunction with a method for implementing the multicast
routing protocol as a transport protocol layer service for endpoints
provides an internet wide multicast transport service. The multicast
transport service provides the capability of transmitting data from a single
source to multiple receivers on interconnected networks efficiently and
without having to send duplicate copies of the data on any single network.
Routers and endpoints transmit and receive multicast packets in a manner
which is independent of the network layer datagram protocols used by the
multicast transport service. Multicast control packets are exchanged using a
multicast transaction protocol which allows routers and endpoints to execute
transactions in a manner that does not require either routers to know the
state of specific endpoints or endpoints to know the state of specific
routers.

>  Multi-level conference management and notification
>
> Abstract
>
> A multi-level conference in which an originator of a telephone conference
> of the multi-level conference controls the parties that can be added to
> that conference and can terminate any party at any time. Further, if two
> existing telephone conferences are combined together to form the
> multi-level conference, the party that originated the combining of these
> two conference calls can control not only the parties on its conference
> call but can disconnect all of the parties on the second conference call.
> In addition, the control of the conference resides in the telephone
> terminals being utilized by the participants, rather than in a centralized
> service computer. Information concerning the conference and control of the
> conference is communicated between the telephone terminals utilizing the
> standard telecommunication communication control channel and does not
> require the establishment of a separate data call to a centralized service
> computer. In addition, the telephone terminals display the names and
> telephone numbers of parties on the multi-level conference and identifies
> parties controlling the individual conferences. In addition, when two
> conferences are combined together, each originator of a conference
> maintains control over their subconference and can independently separate
> that subconference from the other conference in a multi-level conference.
