Abstract
A system for processing packets is disclosed and may including a network interface card (NIC). The NIC may include a TCP enabled Ethernet controller (TEEC). The TEEC may include an internal elastic buffer. The TEEC may process received incoming TCP packets once and may temporarily buffer at least a portion of the incoming TCP packets in the internal elastic buffer. The processing may occur without reassembly or retransmission. The internal elastic buffer may include a receive internal elastic buffer and a transmit internal elastic buffer. The receive internal elastic buffer may temporarily buffer at least a portion of the received incoming TCP packets. The transmit internal elastic buffer may temporarily buffer at least a portion of TCP packets to be transmitted. The TEEC may place at least a portion of the received incoming TCP packets data into at least a portion of a host memory.
