Abstract
The present disclosure provides mechanisms to optimize filter processing. Conventional filter processing techniques involve dividing a batch of received data packets into multiple Access Control Lists (ACLs) per filter group, and thus, cannot leverage of optimal ACL processing of large packet batches using the latest processor instruction sets such as 512 bit wide instructions. The filter processing techniques discussed in the present disclosure, some or all rules for a batch of packets are included in a single ACL look-up by including a filter group identifier (ID) in each rule, and also adding the filter group ID to a field of the packet undergoing the ACL look-up. This avoids false matches while also employing a single ACL look-up for an entire batch of packets, regardless of batch-size. The filter processing techniques can be applied to DOCSIS packet processing pipelines and/or other filtering mechanisms.
