Abstract: A method, computer readable medium, and system are provided for synchronizing a slave clock time with reference time signals received from a master clock. A first basis set of reference time signals received from a master clock is collected. A first comparison set of slave time signals from a slave clock is identified such that each of the slave time signals in the first comparison set correspond with receipt of each of reference time signals in the first basis set. A difference between each of the reference time signals in the first basis set and the slave time signals in the first comparison set is calculated. An average difference between each of the reference time signals in the first basis set and the slave time signals in the first comparison set is then calculated and a slave time kept by the slave clock is adjusted by the average difference.

Abstract: 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.
