Method and system for efficient buffer management for layer 2 (L2) through layer 5 (L5) network interface controller applications

摘要

Method and system for efficient buffer management for layer 2 through layer 5 network interface controller applications are provided. Aspects of the method may comprise determining whether an active NIC connection is an L2 type, an L4 type, or an L5 type. At least one buffer descriptor may be cached locally on a network interface controller (NIC) managed by a NIC application. The buffer descriptor is associated with the determined type of the active NIC connection. If the at least one active NIC connection is of the L2 or L4 type, the buffer descriptor may comprise at least one of a receive (RX) buffer descriptor and a transmit (TX) buffer descriptor. If the NIC connection is of the L5 type, the buffer descriptor may comprise at least one of a upper translation page table (TPT) entry and a lower TPT entry.
