    • A traffic control system (and associated method) according to the present invention includes a feedback control mechanism in which the controlled variable is processor occupancy, the controlling variable is the amount of resources necessary to satisfy the operational requirements of the switching system, and the set point is the average expected load based on a Poisson arrival rate. Current processor occupancy is compared, on an instantaneous basis against the set point to determine if it exceeds the average expected load. If so, the controlling variable is adjusted to allocate additional resources to process the offered traffic load. The process continues until the traffic burst expires. Additional resources may be obtained by eliminating or deferring non-essential work, and by allocating additional call registers, effectively accepting work in larger increments or batches. By instantly and proactively responding to traffic bursts, this traffic control system aids the switching system in weathering brief periods of high traffic, without actually reaching an overload condition and invoking overload controls. As a result, switching system capacity is increased, and other performance characteristics are improved.
    • 根据本发明的交通控制系统(及相关方法)包括其中控制变量是处理器占用的反馈控制机构,控制变量是满足交换系统的操作要求所需的资源量,并且该组 点是基于泊松到达率的平均预期负荷。 当前处理器占用率与瞬时基准值进行比较,以确定其是否超过平均预期负载。 如果是这样,则调整控制变量以分配额外的资源来处理所提供的业务负载。 流程持续到流量爆发到期。 可以通过消除或推迟非必要工作,并分配额外的呼叫记录,以更大的增量或批量有效接受工作来获得更多的资源。 通过立即主动响应流量突发,这种交通控制系统有助于交换系统在短时间内流量高,而不会实际达到过载状况,并调用过载控制。 结果,提高了交换系统容量,提高了其他性能特性。
