Managing bandwidth over a computer network having a management computer that allocates bandwidth to client computers upon request

摘要

Management computers of a packet-switched computer network allocate transmission bandwidth for transmissions such as those for conferences between client computers of the network. Callers and callees request bandwidth from their associated managers for transmissions. Managers monitor and allocate bandwidth taking into account whether the transmissions are between local clients or local and external clients. Managers maintain records of active transmissions, but need not maintain lists of client computers with which the managers are associated.
