Abstract: Introduced here are approaches to classifying traffic that comprises data packets. For each data packet, a classification engine implemented on a computing device can identify an appropriate class from amongst multiple classes using a lookup table implemented in a memory. The memory could be, for example, static random-access memory (SRAM) as further discussed below. Moreover, the classification engine may associate an identifier with each data packet that specifies the class into which the data packet has been assigned. For example, each data packet could have an identifier appended thereto (e.g., in the form of metadata). Then, the data packets can be placed into queues based on the identifiers. Each queue may be associated with a different identifier (and thus a different class).

Abstract: Introduced here are insertion schemes in which queues can be branched into one or more sub-queues for more effective management of queuing elements. Often, a computing device will have a primary buffer into which queuing elements are populated for execution by a processor. However, the amount of contiguous memory space allocated for the primary buffer may be fixed. To address this, a queue manager may insert indicators that link to secondary buffers into the primary buffer in order to expand the number of effective entries in the primary buffer.
