Abstract
Official abstract text for this publication.
In one embodiment, a computer program product includes a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code including computer readable program code configured to initialize an internal look-up table cache provided internally to a switching processor, the internal look-up table cache being configured to store a plurality of look-up entries and being organized into at least three segments: a persistent flows entries segment, a non-persistent flows entries segment, and an access control list (ACL) segment. Each look-up entry relates to a traffic flow which has been or is anticipated to be received by a switching processor configured to access the internal look-up table cache. The computer readable program code is also configured to manage the internal look-up table cache to store entries relating to a particular segment type into a corresponding segment of the internal look-up table cache.
First claim
Opening claim text (preview).
What is claimed is: 1. A system, comprising: a switching processor, comprising: a packet processor, comprising: a look-up interface, fetch and refresh logic (LIFRL) module; and a packet processor logic (PPL) module, wherein the LIFRL module and the PPL module are configured to operate in parallel; and an internal look-up table cache comprising a plurality of look-up entries, each look-up entry relating to a traffic flow which has been or is anticipated to be received by th…
