Abstract
In a network search processor, configured to handle search requests in a router, a scheduler for scheduling rule matching threads initiated by a plurality of initiating engines is designed to make efficient use of the resources in the network search processor while providing high speed performance. According to at least one example embodiment, the scheduler and a corresponding scheduling method comprise: determining a set of bundles of rule matching threads, each bundle being initiated by a separate initiating engine; distributing rule matching threads in each bundle into a number of subgroups of rule matching threads; assigning the subgroups of rule matching threads associated with each bundle of the set of bundles to multiple scheduling queues; and sending rule matching threads, assigned to each scheduling queue, to rule matching engines according to an order based on priorities associated with the respective bundles of rule matching threads.
