Contention resolution in wireless communication systems

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).

The present disclosure describes techniques and apparatuses for a hardware-implemented Adelson-Velskii and Landis' (AVL) tree module. In some aspects, commands are received at the AVL tree module that request operations be performed for an AVL tree table stored in memory. Each command is written to one of multiple hardware threads of the AVL tree module that perform AVL tree operations by causing records of the AVL tree table to be read from memory using a single read operation and then written to the AVL tree module, modifying those records without accessing memory, and causing modified records to be written back to memory using a single write operation. Once a command is written to a hardware thread, the hardware thread can perform the corresponding AVL tree operation. After the AVL tree operation is performed, results are returned to the requesting agent to indicate whether the AVL tree operation was performed successfully.
