Disclosed is a method, apparatus and computer program product for reducing memory power consumption in a server system. The server system includes a memory controller and a plurality of Dual Inline Memory Modules (DIMMs). The method for reducing the memory power consumption includes determining a status of a channel of a plurality of channels of the memory controller. The plurality of channels is associated with the plurality of DIMMs of the server system. The status of the channel represents a presence of at least one scheduled transaction in the channel. The method further includes monitoring the status of the channel by checking whether the status of the channel is in an idle mode for a period of at least equal to a first threshold time. Thereafter, the method includes driving the channel into a power down state based on the monitoring of the status of the channel.

Flow control is provided for a packet switch. An incoming packet is classified according to its priority based on predefined rules to produce a weight value based on the priority of the packet. A lifetime value associated with the packet is produced based on the weight value and the queue occupancy in a queue to which the packet is assigned. The packet is discarded if its associated lifetime value is less than or equal to a threshold value. Otherwise the packet and associated lifetime value are sent to the queue. The lifetime value is periodically changed and compared to a threshold value. The packet is removed from the queue when its lifetime value reaches the threshold value.
