Abstract
Methods for reserving call units of bandwidth and for using the reserved call units to manage call requests are disclosed. Reservations are requested by a first host device (e.g., zone controller) for a path of a packet network communication system. The reservations are granted or denied by the network based on the availability of the requested bandwidth. Once a reservation has been obtained, the number of call units of bandwidth associated with the reservation may be reduced or increased by the network based, for example, on link failures, repairs, etc. Call requests are granted or denied by the zone controller based on the path(s) needed for the call, the number of reserved call units associated with the path(s) and the amount of call units required to support the call. If there are sufficient reserved call units to support the call, the call may proceed by sending, from a second host device (e.g., repeater), a message that is distributed over the number of units of bandwidth needed for the call.
