Abstract
Abstract Client computers on a computer network send messages informing their management computer on the network of the status of transmissions such as those for conferences involving the client computers. Managers use the messages to maintain records of active transmissions to (1) discover transmissions that started without explicit authorization from the managers and (2) delete transmission records corresponding to transmissions that terminated without explicitly notifying the managers.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
126 words
A computer for a computer system comprising a management computer and one or more client computers interconnected over a computer network, wherein: the computer is one of the management computer and a client computer; the client computers can communicate over the computer network; the management computer allocates bandwidth to the client computers for communication sessions over the computer network; each client computer that is participating in an active communication session periodically transmits a message over the computer network to inform the management computer of current status of the active communication session; and if the management computer receives a message from a client computer about a communication session of which the management computer was not previously aware, then the management computer allocates bandwidth for the communication session.
Claim 2
Dependent Claim
126 words
A computer for a computer system comprising a management computer and one or more client computers interconnected over a computer network, wherein: the computer is one of the management computer and a client computer; the client computers can communicate over the computer network; the management computer allocates bandwidth to the client computers for communication sessions over the computer network; each client computer that is participating in an active communication session periodically transmits a message over the computer network to inform the management computer of current status of the active communication session; and if the management computer receives a message from a client computer about a communication session of which the management computer was not previously aware, then the management computer allocates bandwidth for the communication session.
Claim 3
Dependent Claim
14 words
The computer of claim 1, wherein the computer network is a packet-switched computer network.
Claim 4
Dependent Claim
43 words
The computer of claim 1, wherein each message identifies an address for a client computer that sent the message about a communication session, an address for another computer participating in the communication session, and an amount of bandwidth allocated for the communication session.
Claim 5
Dependent Claim
45 words
The computer of claim 1, wherein, if the management computer fails for a specified duration to receive a message from a client computer about a communication session of which the management computer was previously aware, then the management computer deallocates bandwidth for the communication session.
Claim 6
Dependent Claim
57 words
The computer of claim 1, wherein, if the management computer receives a message from a client computer about a communication session of which the management computer was not previously aware and if there is insufficient bandwidth for the communication session, then the management computer instructs one or more of its client computers to terminate their communication sessions.
Claim 7
Dependent Claim
45 words
The computer of claim 5, wherein, if the management computer fails for a specified duration to receive a message from a client computer about a communication session of which the management computer was previously aware, then the management computer deallocates bandwidth for the communication session.
Claim 8
Dependent Claim
116 words
The computer of claim 1, wherein: when the management computer receives a message from a first client computer about a first communication session of which the management computer was not previously aware, then the management computer adds the first client computer and the first communication session to the list and allocates external bandwidth for the first communication session as an external communication session; and if, before the first communication session is terminated, the management computer subsequently receives a message from a second client computer about the first communication session, then the management computer deallocates the external bandwidth for the first communication session and allocates local bandwidth for the first communication session as a local communication session.
Claim 9
Dependent Claim
142 words
The computer of claim 7, wherein: if the management computer fails for a specified duration to receive a message from a client computer about a communication session of which the management computer was previously aware, then the management computer deallocates bandwidth for the communication session; if the management computer receives a message from a client computer about a communication session of which the management computer was not previously aware and if there is insufficient bandwidth for the communication session, then the management computer instructs one or more of its client computers to terminate their communication sessions; the computer network is a packet-switched computer network; and each message identifies an address for a client computer that sent the message about a communication session, an address for another computer participating in the communication session, and an amount of bandwidth allocated for the communication session.
