All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for installing firmware on a network interface controller (NIC) comprising:
accessing a computer readable medium to obtain the firmware; and
installing the firmware on the NIC, wherein the firmware comprises executable instructions for:
receiving a first signal to use a transport layer protocol selected from a plurality of transport layer protocols embedded in the NIC,
determining whether the transport layer protocol is currently available on the NIC;
transmitting, in response to determining that the transport layer protocol is currently available on the NIC, a data packet via a network interface using the transport layer protocol;
receiving a second signal to use a new transport layer protocol, wherein the new transport layer protocol is not in the plurality of transport layer protocols embedded in the NIC when the second signal is received; and
updating the firmware, in response to determining that the transport layer protocol is not currently available on the NIC, to add the new transport layer protocol to the plurality of transport layer protocols embedded in the NIC in response to the second signal.
2. The method of claim 1, wherein at least one of the plurality of transport layer protocols is embedded in the firmware, and wherein at least one of the plurality of transport layer protocols is embedded in the NIC as firmware.
3. The method of claim 1, wherein at least one of the plurality of transport layer protocols is embedded in the NIC as an integrated circuit, and wherein at least one of the plurality of transport layer protocols is embedded in the NIC as firmware.
4. The method of claim 1, wherein the first signal comprises a modified transport layer protocol designation variable stored on the NIC.
5. The method of claim 1, wherein the first signal comprises a stored transport layer protocol designation flag in a header of the data packet.
6. The method of claim 1, wherein the plurality of transport layer protocols comprises at least one selected from a group consisting of transmission control protocol (TCP) Tahoe, TCP Reno, TCP Vegas, TCP NewReno, TCP Hybla, TCP Westwood, TCP Selective Acknowledgement Options (SACK), Hamilton TCP (HTCP), HighSpeed TCP (HSTCP), Binary Increase Congestion (BIC) TCP, Cubic BIC (CUBIC) TCP, Fast Active Queue Management Scalable TCP (FAST), Scalable TCP (STCP), Smart Acknowledgement (ACK) Dropper (SAD), and User Datagram Protocol (UDP).
