Abstract: A system selectively drops data from queues. The system includes a drop table that stores drop probabilities. The system selects one of the queues to examine and generates an index into the drop table to identify one of the drop probabilities for the examined queue. The system then determines whether to drop data from the examined queue based on the identified drop probability.

Abstract: In one embodiment, a method includes sending a configuration signal to a virtual network switch module within a control plane of a communications network. The configuration signal is configured to define a first network rule at the virtual network switch module. The method also includes configuring a packet forwarding module such that the packet forwarding module implements a second network rule, and receiving status information from the virtual network switch module and status information from the packet forwarding module. The status information is received via the control plane.

Abstract: A method performed by an I/O unit connected to another I/O unit in a network device. The method includes receiving a packet; segmenting the packet into a group of data blocks; storing the group of data blocks in a data memory; generating data protection information for a data block of the group of data blocks; creating a control block for the data block; storing, in a control memory, a group of data items for the control block, the group of data items including information associated with a location, of the data block, within the data memory and the data protection information for the data block; performing a data integrity check on the data block, using the data protection information, to determine whether the data block contains a data error; and outputting the data block when the data integrity check indicates that the data block does not contain a data error.
