NIC Method for dynamic packet buffer allocation in multi-core based Network Interface Card

摘要

The present invention relates to a dynamic packet buffer allocation method for packet reception in a multicore-based NIC. In a situation where a packet is inputted from a network to an NIC, a packet buffer engine counts a packet size according to traffic inflow information, reallocates the packet buffer with new packet inflow information, and notifies it to the buffer stack engine. So, it is possible to increase memory usage efficiency and packet processing performance.
