A protocol, method, and apparatus for managing network communications which are particularly well suited for ATM communications across a wireless medium. Contiguous time slots within a frame are allocated to each node having traffic to send. Each node is assured a nominal bandwidth, and excess bandwidth is distributed by demand. The allocation of excess bandwidth can be dependent upon the size of the buffer at each node, as well as the time-criticality of each message. Nodes communicate their requests for allocation by appending such control information to the first of their transmitted packets. The allocation, of each node's transmit and receive time slots, is transmitted to all the nodes at the beginning of each frame. Thereafter, each node need not participate on the network until their allocated time periods, thereby allowing portable devices to enter inactive states to conserve power. The network is operated in a connection mode; connections are established in a relatively non-interfering manner by the use of periodically occurring beacons. Inactive, unconnected, nodes need only monitor the network during these beacon periods, further allowing for power conservation.

A method comprises receiving into a planning tool a representative workload for a consumer. The method further comprises receiving into the planning tool quality of service desires of the consumer which define permitted degraded performance. In certain embodiments, the permitted degraded performance is time-limited wherein demands of the representative workload may exceed a pre-defined utilization constraint for at least one resource servicing the demands for no more than a pre-defined amount of contiguous time. The planning tool determines an allocation of demand of the consumer for each of a plurality of different classes of service (COSs). In certain embodiments, a first COS provides guaranteed resource access for servicing demand allocated thereto, and a second COS provides non-guaranteed resource access for servicing demand allocated thereto. In certain embodiments, the allocation of demand to the different COSs may be determined for both a normal mode and a failure mode of operation.

A method of forecasting, allocating and scheduling in a single or multi-site skills-based contact or call center environment organized into a hierarchy of zero or more business units at a first, upper level, one or more contact types at a second, intermediate level, and one or more management units at a third, lower level. A user creates (a) a set of given contact allocations that define how contacts are distributed from a given business unit to multiple contact types, and (b) a set of given requirement allocations that define how agent requirements are distributed from a contact type to one or more management units. Agent availability by contact type is then predicted to generate agent availability data. Thereafter, forecasted contacts and forecasted agent requirements are allocated based on the given contact and requirement allocations as well as the agent availability data. Preferably, the agent availability data is predicted using a schedule simulator and is characterized by contact type for agents in the same skill group.

A computational network system that permits service a group of technicians access to the manufacturer network to provide their work capacity and availability for a specific area. A customer contacts the manufacturer via the computational network system, requesting a service call. Service call request processing results in assigning a service request/demand to a technician based on their qualifications, availability, and proximity. When a service technician is assigned, their availability is decremented. Cancellation of a service call yields an increment in the affected service provider's availability. This information is stored in a in an on-line database residing in the network system. Updates are dynamically reflected as they occur resulting in automated schedule administration of a customer's service requests/demands.
